252 STAPHYLINIDA. 
Antenne rather short and stout, thickened externally ; third joint short, shorter than 
the second; fifth to tenth each a little broader than its predecessor, so that the 
penultimate joints are rather strongly transverse; terminal joint rather short, not so 
long as the two preceding together. Head small, only about half as broad as the hind 
body, nearly black, finely pubescent, shining, with a large impression on the middle in 
front. Thorax nearly twice as broad as long, narrower than the elytra; hind angles 
very indistinct ; surface very finely punctate, obsoletely impressed at the base in the 
middle. Elytra broad and short, rather longer than the thorax, extremely finely 
punctate. Hind body broad and short, the basal segments clear red, behind this nearly 
black ; all the segments very finely punctate. Breast blackish; under surface of head 
deeply impressed on each side. 
This insect has the hind body unusually broad in comparison with the head ; this 
character, in conjunction with the impressed head, will assist in its identification. Two 
individuals have been found. 
12. Diestota lativentris. 
Brevis, rufescens, antennis extrorsum fuscis, omnium subtilissime punctulata, pube molli erecta vestita ; capite

Hab. Nicaragua, Chontales (Janson). 
Antenne stout; basal joint elongate, red, the other joints darker ; second short and 
stout, hardly half as long as the first; third joint short and stout, shorter than the 
second, nearly as broad as long; fourth rather, tenth very strongly transverse ; terminal 
joint short. Head exserted, but without distinct neck; the eyes are placed quite at 
the front, and behind these it is distinctly narrowed ; in front in the middle it has a 
large impression. Thorax much broader than long, much narrower than the elytra, 
very convex transversely in front, the very depressed front angles obtuse and rounded. 
Elytra longer than the thorax, and like it with a very fine abundant pubescence 
but without distinct punctuation. Hind body broad, only sparingly and extremely 
finely punctate, and but little pubescent. Legs pale yellow. 
Only a single specimen has been found. It appears to be allied to D. microps, but 
with the peculiarities of that species exagerated.
