268 STAPHYLINIDA. 
parcius minus tenuiter pubescens; elytris sparsim punctatis, punctis quasi transversim aciculatis; pro- 
thorace transverso, convexo, basi in medio breviter lateque sublobata, angulis anterioribus obtusis. 
Long. 23-37 millim. 
Hab. Guaremata, San Geronimo, Zapote, Balheu and San Juan in Vera Paz 
(Champion). 
Antenne rather short, distinctly thickened outwardly, black in the middle, yellow or 
nearly so at the base; the apical joint again yellow; basal joint rather short and 
stout, scarcely longer than the second; third joint more slender than and only about 
half as long as the second; fourth rather small, as long as broad; fifth as long as 
broad; tenth decidedly transverse ; terminal joint rather large, obtuse. Thorax almost 
impunctate, with a scanty but conspicuous, rather rigid pubescence. LElytra in the 
middle hardly so long as the middle of the thorax, with a scanty peculiar sculpture 
consisting of short transverse very obscure fine raised lines. Hind body quite sparingly 
punctate, at the base impunctate. Legs yellow. | 
In the male the dorsal plate of the seventh segment of the hind body is narrowed 
towards the extremity and terminates on each side in an elongate spine, and between 
these is produced so as to form a small nearly acuminate lobe. In the female the 
surface of this plate is obscurely granulate, the lateral teeth are smaller, and the 
central lobe is absent or replaced by a very obscure more or less emarginate 
projection. 
Eighteen individuals have been found; they vary a good deal in size and colour, and 
even in the accentuation of the peculiar sculpture of the elytra. 
2. Brachychara brevicornis. 
Ferruginea, antennis fuscis articulo ultimo pedibusque testaceis, his tibiis fuscescentibus, nitida, parcissime 
punctata et pubescens; prothorace convexo, brevi, angulis anterioribus rectis. 
Long. 2 millim. 
Hab. Guatemata, San Juan in Vera Paz (Champion). 
Antenne short, much thickened externally ; third joint short, fourth very small, fifth 
to tenth each rather strongly transverse. Thorax very short and brvad, very convex 
transversely, the base simply rounded, the anterior angles distinct; surface without 
sculpture and with a very scanty pubescence. Elytra in the middle not longer than 
the thorax, very sparingly and obsoletely punctate. Hind body with some punctures 
on the fifth and sixth segments. 
The only individual found is probably a female, the seventh ventral segment being 
armed only with two quite minute rather distant teeth in the middle of its hind mar- 
gin. Although similar to the small individuals of B. crassa in appearance, the species 
is a very distinct one.
