none the less shining, and the lower part of 

 the face is slightly punctate. 



Length of body 17 mm. ; including closed 

 tegmina 21 mm. ; of antennae, 4.5 mm ; teg- 

 mina 15.5 mm; hind femora 12 mm. 



Unfortunately I have but a single 

 specimen, the colors bleached from im- 

 mersion in alcohol. It is a 9 and was 

 taken at Tighes, California, I believe 

 during one of the explorations under 

 Capt. Wheeler. 



There remain the genera of the other 

 division of acrolophitinae which by 

 their gross form, hollowed dorsum of 

 the metazona, long hind tarsi, and short 

 frontal costa, are widely separated from 

 the genera we have considered. Of 

 these I know Daemonea only from 

 Saussure's tiescription, and can only re- 

 fer thereto, but of 



HippACRis Scudder, 

 established on a Peruvian insect, I 

 have before me two species closely re- 

 sembling each other and yet widely dis- 

 tinct, which may be distinguished as 

 follows : — 



Antennae (of $ at least) nearly or quite 

 half as long again as head and pronotum to- 

 gether, tapering regularly ; tegmina relatively 

 slender, being fully four times as long as 

 broad; plates of the ovipositor of normal 



form crassa. 



Antennae (of ? at least) apparently not 

 much longer than head and pronotum to- 

 gether, several neighboring joints in two 

 groups near the middle enlarged and de- 

 pressed, forming broader areas; tegmina rel- 

 atively stout, being less than three times as 

 long as broad; plates of the ovipositor re- 

 duced to simple, straight, tapering, com- 

 pressed laminae without armature 



picticornis. 



To the first species, H. crassa, de- 

 scribed by me (Proc. Bost. soc. nat. 

 hist., 1875, V. 17, p. 268) from the east- 

 ern slope of the Peruvian Andes, I 

 have nothing to add, as the single fe- 

 male then seen is still the only one 

 known to me. The other from the op- 

 posite side of the Andes may be called 



HiPPACRis PiCTicoRXis sp. nov. 



Nearly uniform dull leaf brown. Head 

 punctate, but obscurely excepting on the 

 lower half. Antennae brownish luteous, 

 with the first and second, ninth and tenth, 

 thirteenth to sixteenth and most of seven- 

 teenth joints black, the basal joint brownish 

 luteous on the inner upper surface, the ninth 

 and succeeding joints punctate and of these 

 the black joints depressed and wider than the 

 others. Pronotum with the crested lateral 

 carinae of the prozona and the hinder edge 

 margined with black, and just above the pos- 

 terior lower angle of the lateral lobes a small 

 round luteous spot margined with blackish. 

 Tegmina with all the longitudinal veins, ex- 

 cept in the apical fourth, luteous. Wings 

 faint fuliginous, all the veins blackish fus- 

 cous, and a blackish fuliginous cloud along 

 the edges of the tip. Hind femora blackish 

 at extremity on the outer side; hind tibiae 

 luteo-fuscous, the spines dull luteous, black- 

 tipped, the tarsi dull luteous. 



Length of body 31 mm. ; including closed 

 tegmina 36 mm. ; of antennae (broken beyond 

 19th joint) 17 mm. ; of tegmina 26 mm. ; 

 width of same in middle 10 mm. ; hind fem- 

 ora 15.5 mm. ; tibiae 13 mm. ; tarsi 8 mm.

 The most remarkable thing about this 

 species is the manner in which it differs 

 from the other species and indeed from 

 all acridiodea I have examined in the 

 structure of the ovipositor. Normally,
