tibiae black or blackish, the apical half of all the spines and claws 

 black ; denticulations of ovipositor black. 



Length of body, 26.5 mm.; of antennae, 11.5 mm.; of tegmina, 23.5

34. Coslopterna Stalii nov. sp. 



Top of head and pronotum black, inconspicuously and distantly 

 spotted with yellowish ; rest of head and pronotum, as well as the

 teous, with dusky incisures, at the tip infuscated. Fore and mid- 

 dle legs yellowish, spotted and indistinctly banded with brownish; 

 hind femora dull yellowish, the upper surface with a basal, ante- 

 median and post-median, the outer border with a post-median 

 transverse bar of dark brownish ; hind tibiae dull luteous. Tegmina 

 blackish brown on basal third, beyond subhyaline, with brownish 

 fuliginous transverse clouds, most distinct on inner border. Wings 

 hyaline, with blackish nervures and cross veins, excepting next the 

 costal margin, where they are fulvous.

 which he says "exampla duo valde mutilata examinavi." Among 

 other parts that were wanting were the hind tarsi, which are very 

 peculiar in the species which I have the pleasure to add to this group. 

 They are excessively slender and strongly compressed ; so minute is 

 the middle article that at first I thought them but two-jointed ; the 

 first and third joints are equal in length, and either of them scarcely 

 longer than the produced, depressed sulcate apical spines of the 

 tibiae, between which the basal joint lies; there is a small but well 

 formed pad. 



35. Tettigidea cuspidata nov. sp. 



Blackish brown, the head a little paler ; frontal carina of the head 

 compressed, rather prominent, sulcate from the middle of the eyes 

 downward. Whole head and pronotum as well as hind femora cov- 

 ered rather profusely with minute depressed granulations, giving a 

 brighter appearance to the insect from their reflection of the light. 

 Pronotal shield extending behind nearly to the tip of the posterior 

 femora, the front border angulated, and the compressed, slightly ele- 

 vated, but very distinct, median carina produced anteriorly to a sharp
