SCIOCHARIS. 573 
10. Sciocharis championi. 
Testacea, capite nigro, prothorace fusco, elytris apicem versus fuscescentibus, opaca, dense subtilissime punc- 
tata; prothorace minus fortiter transverso, elytris angustiore, in medio linea levigatas distincta. 
Long. 33 millim. 
Hab. GuaTEMALa, Coatepeque (Champion) ; Panama, David (Champion). 
This species has the base of the head rather rounded, its surface very densely and 
finely punctate, quite dull, the eyes occupying one half of the length of the sides. The 
thorax considerably narrower than the elytra, all the angles broadly rounded, the 
surface very densely and finely punctate, the smooth line along the middle very 
definite, not canaliculate. Elytra very densely and finely punctate, quite dull. The 
front tarsi are slightly dilated, and the male has a very broad rather shallow emargina- 
tion of the last ventral plate. 
Six examples from Guatemala, one from the State of Panama; this latter in bad 
condition and not certainly the same species. 
11. Sciocharis densicollis. 
Ferruginea, capite prothoraceque fusco-ferrugineis, elytris circa suturam fuscis, antennis pedibusque testaceis ; 
capite prothoraceque omnino densissime punctatis, opacis, illo subquadrato, posterius recte truncato. 
Long. 3 millim. 
Hab. Panama, David (Champion). 
Head quite truncate behind, the eyes occupying one half of the length of the sides. 
Thorax much narrowed behind, excessively densely and minutely punctured, quite dull, 
with a narrow, indistinct, canaliculate smooth line down the middle. Elytra quite dull, 
very densely punctate. 
This species is readily distinguished from S. champion by the shape and colour of 
the head ; it is, moreover, a broader insect. The front tarsi are feebly dilated, and the 
male has a broad shallow emargination of the last ventral plate. Six examples. 
12. Sciocharis gregaria. 
Ferruginea, capite fuscescente, elytris plus minusve late infuscatis, omnino densissime vix visibiliter punctu- 
lata, opaca. 
Long. 33 millim. 
Hab. Guatemaa, San Gerénimo (Champion). 
Of very parallel form. Head subquadrate, not rounded behind, the eyes occupying 
one half of the length of the sides; surface dull, not visibly sculptured. Thorax also 
dull, and almost without visible sculpture, with very faint trace of a channel along the 
middle. Elytra densely and finely punctate. Front tarsi distinctly dilated. Male 
with a small excision at the narrow extremity of the last ventral plate. 
Nearly three dozen examples were obtained of this species. The antenne are 
extremely delicate and are broken off from nearly all the specimens.
