192 STAPHYLINIDA. 
Six specimens have been found; but most of them are in fragments, having been 
attacked by Acari during their journey to this country. 
42, Homalota basiventris. 
Breviuscula, subdepressa, subtilius punctulata, et pubescens, fusca, antennarum abdominisque basibus pedi- 
busque testaceis; antennis brevibus, apicem versus fortiter incrassatis ; prothorace fortiter transverso, 
basi rotundata; abdomine parce punctato. 
Long. 17 millim. | 
Hab. Panama, Volcan de Chiriqui, between 2500 and 4000 feet (Champion). 
This minute insect has somewhat the appearance of a species of Oligota. The 
antennee are very short and very much thickened externally; the three or four basal 
joints are yellow, the others dusky; second joint short and stout; third joint slender at 
the base, thickened outwardly, much shorter than the second; fourth and following 
joints very short, each strongly transverse; terminal joint rather short, with obtuse 
apex. Head much narrower than the thorax, this latter quite twice as broad as long, 
strongly rounded at the base and also at the short sides, feebly punctate. Elytra a 
good deal longer than the thorax, feebly and not densely punctate. Hind body finely 
and not densely punctate, the basal segments yellowish. 
The unique individual appears to indicate a species allied to H. discrepans and its 
neighbours, but with short, thick antenne. 
43. Homalota championi. (Tab. V. fig. 11.) 
Elongata, crebrius punctata, haud nitida, capite, pectore abdomineque late ante apicem nigris; thorace abdo- 
mineque basi et apice rufo-testaceis; antennis fuscis, basi cum pedibus testaceis; elytris fusco-testaceis. 
Long. 3-33 millim. 
Hab. Gvuaremata, Capetillo, Carrizal, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne rather long, but little thickened towards the extremity; third joint 
elongate, rather longer than the second; fifth to tenth differing but little from one 
another, the first of them as long as broad, the last of them rather broader than long ; 
terminal joint obtuse, as long as the two preceding together, a little paler at the tip. 
Head rather small, short and broad, rounded behind the eyes, dull, scarcely visibly 
punctate. Thorax not quite so long as broad, nearly straight at the sides, and scarcely 
narrowed behind, very finely punctate and closely pubescent. LElytra longer than the 
thorax, closely and distinctly punctured. Hind body rather elongate, subparallel; the 
two basal segments yellowish red, the following two and a half segments black, the 
extremity again brightly coloured ; segments two to four are rather closely, five and six 
more sparingly punctate. Legs clear yellow. 
In the male the dorsal plate of the sixth ventral segment bears numerous irregularly 
placed raised granules, some of them very small, others elongate and linear; the hind 
margin of the seventh plate is prominent in the middle, and emarginate so as to form
