Courting green lacewings of Chrysopa carnea Stephens, C. downesi Banks, and several other species communicate with their partners by exchanging acoustical signals produced by vigorous jerking of the abdomen. Intraspecific communication was unaffected when an area of microtrichia associated with a possible stridulatory structure was excised from the wing of a sexually receptive C. carnea male. Additionally, no high-frequency audio sounds were detected by analysis of oscillographs; however, males and females of C. carnea and C. downesi responded to recordings of conspecific calls when the low-frequency oscillations were transmitted to a compliant substrate and when all high-frequency information was filtered out. Therefore, exchange of low-frequency substrate oscillations is sufficient for intraspecific communication in the lacewing species studied. Evolutionary implications are discussed briefly.

Insects make use of sound in a variety of behavioral and reproductive contexts. Acoustic signals are known to serve in defense, sexual advertisement, prey location, and in cooperative activities such as offspring care and group foraging. In airborne signals produced by insects, information associated with species identiÞcation is often related to the temporal structure of the sound, while spectral quality is more closely associated with intraspeciÞc variation. The Nicrophorine burying beetles (Insecta: Coleoptera: Silphidae) are a group known to produce sound through dorso-ventro stridulation, but the bioacoustics of this group remains understudied. Here, we examine the stridu- latory sound produced by eight North American species of Nicrophorus burying beetles, testing the hypothesis that interspeciÞc differences will be encoded in temporal characteristics of the sound, and that signal divergence will be explained by one of three mechanisms: selection as an intraspeciÞc signal, selection for interspeciÞc aposematism, or random divergence through drift. We digitally recorded stridulation in each species, and analyzed recordings to describe each in respect to four spectral and eight temporal acoustic characters. All species produced a low amplitude biphastic sound pulse consisting of from 58 to 126 syllables, and exhibiting weak dominant frequencies (5.8Ð12.7 kHz). Collapsing the 12 variables into three rotated factors using principal component analysis, we found no sex-related differences in sound, but signiÞcant interspecies divergence in respect to all three factors. We constructed a phylogeny for the group based on the morphology of the stridulatory structures and the acoustic characters, and found weak support for an intraspeciÞc signal divergence model.

While associated with the Oregon Agricultural Experiment Station, from 1919 to 1924, the writer collected and studied the Orthoptera of the state as opportunity permitted while carrying on the regular economic work. The more important results of these studies are brought together in this paper, which is not intended as a complete list of the Orthoptera of Oregon. The part on distribution and ecological relations is placed last so that reference to new species and races will not precede their description.

Cyphoderris monstrosa Uhler, one of only 2 species of Prophalangopsidae in the United States, produces intense short trills at about 13 kilohertz at 25°C. Pulse rate averages 71.4 per second and trill duration ranges from 0.5 to 2.0 second. Males switch wings regularly while calling, a phenomenon not typical in Gryllidae and Tettigoniidae.

Investigation of 4 species of the subfamily Lamiinae—Tylocerina nodosus (F.), Neacanthocinus obsoletus (Olivier), Monochamus titillator (F.), and Plectrodera scalator (F.)—shows that both sexes of each species produce a stridulatory sound when disturbed. The stridulatory apparatus of each species consists of a plectral ridge on the inner surface of the posterior margin of the pronotum and a pars stridens on the dorsal surface of the mesocutellum of the mesothorax. Scanning electron micrographs show the plectral ridges to be smooth, while the pars stridens consists of regularly spaced striae with height, width, and spacing measurements characteristic for each species. Audiospectrographic analysis of the beetle-produced sounds reveals definite frequency bands, pulse lengths, and relative intensities for each species. Investigation of behavioral aspects of the sounds indicates that they are not a necessary component of courtship and mating behavior, but they may serve as an alarm signal.

In Atlanticus gibbosus Scudder the wing-cycle rate during stridulation is a linear function of temperature: ŷ = 1.35 T — 9.56 (T = °C; r2 = .99). In A. dorsalis (Burmeister) the tooth-strike rate during stridulation can be described approximately as either a linear or an exponential function of temperature: ŷ = 33.55 T — 268.32 (r2 = .96) or Ln ŷ = .065 T + 4.523 (r2 = .96). Humidity and aging had statistically significant but ecologically unimportant effects on stridulatory rates. In A. gibbosus the wing-cycle rate at low humidities (25±5% RH) was reduced to the extent expected from 0.7°C evaporative cooling. In A. dorsalis aging beyond ecological life expectancy caused an increase in tooth-strike rate and the occurrence of gaps in the tooth-strike sequence.

In Israel, sexually mature adults of the sibling species of grashoppers Acrotylus insubricus (Scopoli) and A. patruelis (Herrich-Shaffer) occur both allopatrically and sympatrically. To distinguish between the 2 species in areas of sympatry and to help resolve their confused taxonomy, nonmorphological criteria were sought. The mating and acoustic behavior of these species and some aspects of their biology were therefore studies.

No species-specific differences in mating or acoustic behaviour were found. Stridulatory songs of the 2 species were similar for all parameters studied, as was substrate drumming, studied both as airborne sound and solidborne sound (i.e., substrate vibrations). No response to playback of either form of sound, or of substrate vibrations as such, was obtained under the conditions of our experiments.

Under identical conditions of incubation, eggs of A. patreulis hatched in a significantly hsorter time than those of A. insubricus, and gave rise to uniformly grey nymphs differing from the black-headed, light-bodied nymphs of the latter species. Under "no-choice" laboratory conditions, F1 hybrids were obtained from each of teh reciprocal parental crosses. Songs of hybrid males could not be distinguished from those of the parent species.
