SCIOCHARIS. | 571 
Hab. Guatemata, near the city, Capetillo, and Tamahu (Champion). 
So far as I can see this insect differs from S. nigriceps only by the smaller eyes, which 
not only are less convex, but occupy considerably less than one half of the length of the 
sides of the head, and by the punctuation on the basal portion of the thorax being less 
extremely dense and fine. The median line on the thorax is distinct and is canaliculate 
at the base. The front tarsi are very feebly dilated, and the male has only a broad 
shallow excision of the last ventral plate. 
Four examples. 
4. Sciocharis similaris. 
Fuscula, subtiliter sed evidenter pubescens, omnino densissime punctata, opaca, capite nigricante, prothorace 
fusco, antennis pedibusque rufis, elytris sordide testaceis; capite subquadrato, posterius recte truncato, 
angulis posterioribus nullo modo rotundatis. 
Long. 5 millim. 
Hab. GuateMaa, Aceytuno (Champion). 
This species is extremely similar to S. nigriceps, though readily distinguished by the 
more sharply defined hind angles of the head. The punctuation of the head is excessively 
dense, so that the surface is minutely and finely yet roughly rugose; the thoracic punc- 
tuation too is excessively dense; there is no definite smooth line on the thorax, but a 
fine channel extends nearly the whole length. The emargination of the last ventral 
segment in the male is broader and less deep than it is in S. nigriceps, and the front 
tarsi are distinctly dilated. Unique. 
5. Sciocharis capitata. 
Subrobusta, ferruginea, capite prothoraceque fusco-ferrugineis, omnino densissime subtiliter punctata, opaca ; 
capite majore, elytris fere latiore, posterius emarginato-truncato, angulis posterioribus fere acutis. 
Long. 5 millim. 
Hab. Panama, David (Champion). 
This insect is much larger than S. nigriceps, and is readily distinguished from that 
species by the shape of the head. The punctuation of the head is excessively dense, 
subobsolete; on the posterior part of the thorax the sculpture is less dense and fine, so 
that the surface there is very feebly shining ; the channel in the median smooth line 
extends almost all the length. The elytra are only slightly longer than the thorax, very 
densely, finely punctate. The unique example is apparently a female; the front tarsi 
are feebly dilated.
