himself placed this genus at first in the Ithyporides, later ** in 
the “Genera incertae sedis.” Finally, J. Faust *° has described 
a new species of Apries, histrio, from Burma, but without men- 
tioning the aberrant formation of its rostral canal, limited be- 
hind (similar to Mecistocerus) by the metasternum which forms 
a sinuate edge between the intermediate cox and, therefore, 
this species could be classified by others with more right as of 
the Sophrorhinides; but in the latter tribe the rostral canal is 
limited laterally by two lamelle on each side, one on the pro- 
sternum behind the coxee, and the other on the mesosternum. 
All these facts, and a series of Philippine genera, partly related 
to Deretiosus and partly to Colobodes and Apries, have brought 
me to the opinion that departure from Lacordaire’s arrangement, 
without resynopsizing the genera, is not to be recommended, as it 
would only augment the confusion in this difficult chapter of 
taxonomy; it is impossible to treat the genera mentioned with- 
out considering their relation to others. Therefore, I give here 
a preliminary key of the genera which belong partly to the 
Ithyporides and partly to the Sophrorhinides, Lacordaire’s two 
“Sous tribus,” which are hardly to be separated even in the sense 
in which that meritorious author separates them. 
Key of genera allied to Colobodes, Deretiosus, and Apries. 
Neither the postcoxal part of prosternum nor the sides of metasternum 
with a lamella limiting the rostral canal laterally as is the case 
in Mecistocerus. 
a’. Ocular lobes distinct (indistinct only in Thisus Pascoe). 
b*. Anterior coxe remote. 
ec’. Intercoxal process of metasternum between the intermediate coxe# 
slightly declivous, passing off into a plane with the mesosternum. 
Funicle of antenne 7-jointed. 
d’. Intercoxal process of mesosternum narrower than the diameter 
of intermediate coxe. 
e’. Femora strongly clavate and dentate, almost extending beyond 
the fourth sternite. 
f’. Seutellum bare. 
g’. Rostrum more than four times longer than thick, apex 
of scrobes not visible from above and nearer to the 
middle than to the apex Colobodes Boh. 
g’. Rostrum shorter, apex of scrobes visible from above. 
Eucolobodes g. nov. 
f’. Scutellum tomentose Deretiosomimus g. nov.
