570 STAPHYLINIDZ. 
1. Sciocharis arribalzagz. (Tab. XIV. fig. 23.) 
Fusco-rufa, densissime punctata, antennis pedibusque testaceis; capite quadrato, posterius recte truncato, 
oculis convexis, densissime vix subtiliter punctato; prothorace transverso, posterius angustato, densius 
fortiusque punctato, medio linea angusta levigata ; elytris densissime subtiliter subrugose punctatis. 
Long. 43-5 millim. | 
Hab. Guatemaua, near the city, Capetillo, San Gerénimo (Champion). 
First and second joints of the antenne moderately thick. Head quite straight behind, 
not at all emarginate, the hind angles remarkably definite, the convex eyes extending 
more than halfway to the vertex, opaque, the rather coarse punctuation as dense as 
possible. ‘Thorax more shining than the head, and rather more coarsely punctate, the 
narrow smooth line more or less distinctly canaliculate behind. Elytra infuscate- 
ferruginous, the humeral and lateral regions usually less infuscate. The male has a 
moderate angular excision on the last ventral segment. 
I have named this insect in honour of the accomplished author of the memoir styled 
‘‘ Los estafilinos de Buenos Aires,” to whom we are indebted for the generic characters 
of Sciocharis. The species is allied to the Amazonian Lithocharis quadrata, Sharp, 
but differs in numerous details. 
Seven examples from the city of Guatemala, one from each of the other localities. 
2. Sciocharis nigriceps. 
Fusco-rufa, omnino densissime punctata, opaca, capite nigricante, prothorace fusco, antennis pedibusque 
testaceis ; capite subquadrato, posterius truncato, angulis posterioribus leviter rotundatis; elytris sordide 
testaceis, regione suturali fusca. 
Long. 4 millim. 
Hab. GuateMaua, near the city, San Gerdnimo (Champion); Panama, Volcan de 
Chiriqui (Champion). 
In this species the hind margin of the head is straight, not emarginate, the hind 
angles, however, being a little rounded. The thorax is as densely and finely punctate 
as the head, and the smooth line down the middle is correspondingly definite, it is 
feebly canaliculate at the base. The elytra are very finely punctate. The front tarsi 
are scarcely dilated. 
This insect is readily distinguished from 8S. arribalzage@ by the punctuation of the head 
and thorax, as well as by the much less definite hind angles of the former, the smaller 
eyes, almost undilated front tarsi, &c. It is nearer to the Amazonian Lithocharis egena, 
Sharp, from which it differs in numerous details. 
Four examples. 
3. Sciocharis cognata. 
Fusco-rufa, omnino densissime punctata, opaca, capite nigricante, prothorace fusco, antennis pedibusque 
testaceis ; capite subquadrato, posterius truncato, angulis posterioribus leviter rotundatis ; elytris sordide 
testaceis, regione suturali fusca. 
Long. 4 millim.
