122 Psyche [March-June 
eyes for half their length; sunken area traversed by a strong 
median carina; anterior margin curving uninterruptedly on to 
frons; frons much longer than broad (1.5 to 1), lateral margins 
sinuately expanding to near apex, thence incurved to suture; 
median carina forming a distinct raised band; clypeus medially 
and laterally carinate. Pronotum in middle scarcely two-thirds 
as long as vertex, anterior margin of disc convex, heavily cari- 
nate; disc narrow, subtriangular, sides not strongly diverging 
posteriorly; median carina very thick; lateral carinse of disc 
less so, a pair of carinae on each side of pronotum near and at 
lateral margins; mesonotum about twice as wide as long, flat- 
tened, tricarinate, lateral carinae not converging posteriorly. 
Post-tibiae trispinose. 
Tegmina with Sc+R+M stalk very short, Sc+R and M not 
forked before nodal line, Cul forked a short distance before 
nodal line; fourteen apical cells, six subapical; apex of clavus 
not reaching to middle of commissural margin, membrane dis- 
tinctly larger than corium. 
Genotype, A. rubrovittata Schmidt 1932 Stett. Ent. Zeit. 93:39. 
Achilorma fowleriana Kirk, is placed in this genus. The 
type locality of fowleriana is given as Teapa in Tabasco, 
Mexico. Specimens examined by the writer came from 
Teapa, Mexico. Specimens examined by the writer came 
from Teapa, Mexico and Cerro Zunil, Guatemala. The 
small fork of Cul before the nodal line is variable.

Genotype, C. furcata Uhler loc. cit. 511. 
This genus must be placed in the Paricanini as the structure 
of the frons, vertex, pro- and mesonotum and the tegminal 
venation are characteristic, though the apex of the clavus is 
distad of the middle of the commissural margin.
