but deeply punctate, smoother on the basal part, and with an elevation on each side 
near the base. Legs rather stout, yellow, with a definite infuscation of the apices of 
the femora. The male has a slight broad emargination of the last ventral plate. 
Though similar in the colour of the legs to S. cribripennis, S. femoratus has a 
broader thorax, almost without channel along the middle, and more finely punctate 
wing-cases. Unique. 
7. Stilicus simplex. | 
Niger, opacus, antennis, palpis pedibusque testaceis, coxis fuscis ; minus gracilis, prothorace lato, medio obso- 
lete canaliculato; elytris densissime punctatis. 
Long. 5 millim. 
Hab. GuatreMa.a, near the city (Champion). 
Head broad and short, excessively densely punctate. Thorax broad, but distinctly 
narrower than the elytra, about as long as broad, very densely punctate, and with a 
very indistinct channel along the middle. Elytra broad and short, slightly longer than 
the thorax, and of a rather more fuscous colour than the anterior parts, and scarcely so 
dull, though very densely, evenly, and rather deeply punctate. Legs stout, yellow. The 
male has a very slight gradual emargination of the hind margin of the last ventral 
plate. 
Only two examples have been obtained. 
8. Stilicus chiriquensis. 
Niger, antennis, palpis pedibusque testaceis, coxis fuscis; capite prothoraceque dense fortiterque punctatis, fere 
opacis, hoc sat lato, medio minus distincte canaliculato ; elytris sat nitidis, crebrius subtiliter punctatis. 
Long. 53 millim. 
Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 
This species has a broad, short, very densely punctate head, and a moderately broad 
thorax, only obsoletely canaliculate along the middle. The elytra are short and broad, 
shining, distinctly and finely, though by no means densely, punctate, with an elevation 
near the base on each side of the suture, and a shallow longitudinal depression 
external to this; they are not longer than the thorax. The male has a shallow angular 
excision on the last ventral segment. 
Readily distinguished from S. simplex by the shining, less densely punctate elytra. 
Seven examples. 
9. Stilicus rugicollis. 
Elongatus, niger, elytris subseneis, antennis pedibusque testaceis, palpis femorumque posteriorum apicibus fuscis, 
coxis nigris; prothorace elongato, angulis lateralibus prominulis, omnino fortiter rugoso-punctato ; elytris 
dense sat fortiter substrigoso-punctatis. 
Long. 6-63 millim. 
Hab. Payama, Volcan de Chiriqui 2500 to 4000 feet (Champion).
