there, it is in the highest degree improbable that it will prove to be identical with the 
above mentioned insect from Colombia. 
Ten examples. 
4, Stilicus cribripennis. 
Nigro-subzeneus, antennis fusco-testaceis, pedibus testaceis, femoribus apice, coxis anterioribus palpisque fuscis ; 
capite prothoraceque dense fortiterque rugoso-punctatis, hoc medio longitudinaliter canaliculato; elytris 
dense profunde fortiterque punctatis, nitidis. 
Long. 44 millim. 
Hab. Mexico, Cordova (Sallé); Guatmmata, Cerro Zunil 4000 to 5000 feet, Duefias 
(Champion). 
This species is readily distinguished from 8. guatemalenus by the thorax being 
canaliculate along the middle instead of furnished with a polished raised space; the 
colour of the legs and palpi is also characteristic. The head and thorax are rather 
broad; the elytra short and broad, scarcely longer than the thorax, coarsely and very 
densely punctate, uneven. ‘The male has a broad excision of the terminal ventral plate ; 
the hind margin of the preceding segment simple. 
The unique Mexican exponent is quite similar to the small series of Guatemalan 
individuals. 
5. Stilicus nimborum. 
Niger, minus eenescens, antennis fusco-testaceis, pedibus palpisque fuscis, femorum basi tarsisque testaceis ; 
eapite prothoraceque dense fortiterque rugoso-punctatis, hoc medio longitudinaliter canaliculato ; elytris 
dense profunde fortiterque punctatis. 
Long. 53 millim. 
Hab. Guatumata, Quezaltenango 7800 feet (Champion). 
We have received only one mutilated female of this species, and except for the colour 
of the legs it almost exactly resembles S. cribripennis; as this character is, however, of 
specific importance in this genus, I have no doubt the two will prove to be distinct. 
6. Stilicus femoratus. 
Niger, opacus, elytris subenescentibus, subnitidis, pedibus testaceis, femorum apicibus, antennis palpisque 
fuscis; minus gracilis, capite prothoraceque dense fortiterque rugoso-punctatis, hoc medio vix perspicue 
canaliculato; elytris crebrius minus fortiter punctatis, 
Long. 53 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion). 
Head broad, transversely subquadrate, excessively densely punctured, quite dull. 
Thorax broad, but distinctly narrower than the elytra, scarcely longer than broad, 
much narrowed in front; lateral angles distinct, with only an indistinct trace of a 
channel along the middle. Elytra broad and short, about as long as the thorax, finely
