494 STAPHYLINIDA. 
11. Lithocharodes fuscula. 
Gracilis, rufo-fusca ; elytris fuscis, apice rufescente, antennis pedibusque testaceis; capite oblongo, anterius 
leviter angustato, crebrius punctato, linea mediali angusta levigata; thorace gracili, anterius latiore, 
_erebre fortiter punctato, linea mediali levigata; elytris subtilius parce punctulatis, quam thorax haud 
longioribus ; capite subtus crebre fortiter punctato. 
Long. 43 millim. 
Hab. GuatTeMAta, near the city, San Gerénimo (Champion). 
The six examples before me do not exhibit any sexual character. Found beneath 
dead leaves &c., on the sandy banks of streams. 
12. Lithocharodes rufula. 
Gracilis, rufa; pedibus testaceis, elytris disco subfuscescente, pedibus testaceis ; capite oblongo, anterius angus- 
tato, crebrius punctato, linea mediali angusta levigata; thorace gracili, anterius latiore, crebre fortiter 
punctato, linea mediali levigata; elytris quam thorax: paulo brevioribus, subtilius punctatis; capite subtus 
crebre fortiter punctato. 
Long. 44 millim. 
Hab. GUATEMALA, near the city, Pantaleon, Rio Naranjo (Champion). 
The three individuals do not exhibit any sexual characters. The species is distin- 
guished from L. fuscula chiefly by the rufescent colour. Found on the sandy banks 
of streams. 
13. Lithocharodes collaris. 
Fusca ; capite elytrisque nigris, thorace antennarumque basi rufis, pedibus testaceis ; capite anterius angustato, 
densius fortiterque punctato, linea mediali laevigata, angusta; thorace crebrius fortiter punctato, linea 
mediali levigata; elytris quam thorax haud longioribus, sat crebre minus subtiliter punctatis; capite 
subtus crebre fortius punctato. 
Long. 6 millim. 
Hab. Guatemata, Cubilguitz in Vera Paz 1000 feet (Champion). 
The only example found has no peculiarity by which I can form an opinion as to 
its sex. 
SOMOLEPTUS. 
Statura minor, forma gracilis. Caput elongatum, collo angusto. Palpi maxillares articulo ultimo tenue, 
lineari, basi quam articulus precedens multo angustiore. Antenne scapo magno; sulci antennarii inter- 
medii obsoleti, laterales nulli. Thorax anterius angustus, pleuris haud abbreviatis. Coxe intermediee 
sat distantes. Tibie espinulose ; tarsi omnes graciles. 
This genus will include some small but graceful forms of Xantholinina allied to 
Leptacinus, but differing by the more elongate anterior portion of the thorax and its 
larger pleure, by the obsolete antennal furrows, and the slender legs destitute of 
spinules; the species have a peculiar facies by which they are readily recognized, and 
which depends, I think, chiefly on the shape of the thorax and the large scape of the 
antenne. In these respects they agree with the eastern genus Mitomorphus, Kraatz,
