39. Acriclium ( Osmilia ) saussurei, Proc., 17, 274; Ent. Notes, 
4, 28. 1875. Peru. 
A true Osmilia. 
40. Aeolacris (octomaculata) , Proc., 17, 269; Ent. Notes, 4, 23. 
1875. 
This genus was founded on my Xiphicera octomaculata; it is a 
genus of Tropidonoti, allied to Alophonota Stai. 
41. Aplatacris colorata , Proc., 17, 271 ; Ent. Notes, 4, 25. 
1875. Peru. 
Brunner has correctly placed this genus (Rev. Syst. Orth., 134). 
It differs from Tropidaeris Scudd. in its more robust form, some¬ 
what abbreviated organs of flight, the tegmina with open recticula- 
tion and exceedingly few longitudinal veins, and the wings also with 
more open reticulation; the frontal costa is percurrent, and the 
mesosternal lobes, especially in the male, considerably elongated 
exteriorly ; the subgenital plate of the male is much shorter. 
42. Astroma hastata, Proc., 17, 266; Ent. Notes, 4, 20. 1875. 
Peru. 
This is a Cephalocaema (which is not congeneric with Astroma) 
closely allied to my C. acuminata , having the basal joint of the 
antennae of similar brevity and with 10-12 spines on the margins 
of the hind femora, but with the prothorax smooth or only very 
faintly and transversely wrinkled. The species was not noticed by 
Brunner in his Monograph of the Proscopinae. 
43. JBrachystola behrensii , Proc., 19, 33; Ent. Notes, 6, 11 ; 
Cent. Orth., 50. 1877. Mexico. 
Belongs to Brachystola. 
44. Cephalocaema acuminata , Proc., 12, 337 ; Ent. Notes, 2, 
22. 1869. Peru. 
This was afterward (Proc., 17, 266 ; Ent. Notes, 4, 20) placed by 
me in Astroma, under the supposition that these genera were syn¬ 
onymous. It differs from C. sica (Serv.), besides the points men¬ 
tioned by Brunner (Mon. Prose., 31), in having but 11-12 spines 
on the margins of the hind tibiae ; the basal joint is short as in 
that species, next which it must be placed. 
45. Chrysochraon? abbreviation, Proc., 12, 339; Ent. Notes, 
2, 24. 1869. Peru. 
Belongs to Orphulella Giglio-Tos. 
46. Coelopterna stalii, Proc., 17, 277 ; Ent. Notes, 4, 31. 1875. 
Peru. 
This genus is referred to a distinct family, Coelopternidae, by
