THE CANADIAN ENTOMOLOGIST. 73 



lanceolate, a little curved upwards and extending about one-fourth of an 

 inch beyond the closed tegmina. 



General colour bright grass-green, with yellowish lines along the lateral 

 carina; of the pronotum. Posterior tibiae together vvith all the feet more 

 or less infuscated. Antennae testaceous or rufous.

■Habitat. — Found throughout the eastern part of the State, where it 

 occurs most frequently in the natural groves growing along our principal 

 streams. I have also seen specimens of it that were taken in Iowa and 

 Illinois, and have specimens from both of these last named States in my 

 collection. 



Amblycorypha Scudderce, n sp. — Very similar to, but smaller than the 

 A. oblongifolia. 



Pale to dark green. Disk of the pronotum flat, gradually expanding 

 posteriorly ; the lateral angles or shoulders quite sharp ; the lateral lobes 

 with their posterior lower edge broadly rounded. Tegmina quite heavy 

 and opaque, rather rough and of a dull green colour — especially so in the 

 female specimens ; the costal area full and evenly rounded. Posterior 

 femora moderately stout, slightly surpassing ($) or not quite reaching (^ ) 

 the tips of the tegmina, their inner margin furnished with 7 or 8 short 

 spines. " Shrilling " field of the tegmina large and flat, as in oblongifolia, 

 a little broader than the posterior extremity of the pronotum. Ovipositor 

 evenly curved, the apical third strongly toothed.

One of our commonest katydids throughout the eastern or wooded 

 portion of Nebraska. It is especially numerous among the groves of 

 oaks and other hard wood trees. 



Like oblongifolia, this katydid produces the peculiar chick-chick noise 

 which is so characteristic a sound in our groves at night during the months 

 of August and September. Scudderce is to be distinguished from that 

 species by its smaller size, the more evenly rounded or arcuate edges of 

 the tegmina, the comparatively shorter hind legs, and the more strongly 

 serrated point of the female ovipositor.
