702 STAPHYLINIDA. 
In this species the tip of the scutellum is minutely exposed, as in the genus T’hino- 
dromus, Kr. 
14. Trogophleus mollis, (Tab. XVIII. fig. 18.) 
Niger, femoribus antennarumque articulo basali rufo ; densissime subtilissimeque punctatus et pubescens ; capite 
lato, posterius truncato ; prothorace brevi, dorso impresso, ante basin curvatim depresso. 
Long. 33 millim. 
Hab. GuatTEMALA, Coban, San Gerénimo (Champion) ; Panama, David (Champion). 
Antenne rather short, the penultimate joint slightly transverse. Head very broad, 
rather broader than the thorax. Thorax strongly transverse, much narrower than the 
elytra ; with a large depression on the disc, a curvate depression behind this, and a vague 
depression near each side. LElytra like the thorax, very finely, scarcely perceptibly 
punctulate. Five examples. 
Closely allied to the Cuban 7. croceipes, Fauv. 
15. Trogophleus vittatus. (Tab. XVIII. fig. 19.) 
Niger, antennarum articulo basali pedibusque testaceis ; subtilissime punctulatus et pubescens; elytro singulo 
juxta suturam testaceo-vittato. 
Long. 3 millim. 
Hab. GuatemaLa, Coban (Champion). 
Head not broad, but little truncate on either side behind the eyes. Thorax obso- 
letely bi-impressed on the disc and at each side, but with a deep curvate basal depression. 
Elytra with a broad, longitudinal, pallid vitta very close to the suture. Unique. 
This species resembles 7. mollis in the excessively fine punctuation and pubescence, 
but differs from it in numerous other characters. 
TROGACTUS. 
Corpus gracile, haud depressum. Antennis pedibusque gracilibus. Palpi maxillares sat elongati; articulo 
ultimo minutissimo, setiformi. Scutellum parvum. 
These elegant insects are allied to Trogophleus, but differ strikingly by their long 
limbs, and the visible scutellum. The palpi are rather long; the pseudo-terminal 
joint slender, but still a little broader than that preceding it; the terminal joint is 
peculiar, and being like a small hair (truncate at the extremity, and not at all thicker 
at the base) is only visible with a strong magnifier. The front coxe are rather long, 
vertical, and their cavities have scarcely any extension outwards towards the front 
angles of the thorax. 
There are no known Staphylinide very similar in appearance to the species of this 
genus. These insects are found, Mr. Champion informs me, on the sandy banks of 
mountain streams in the forest.
