STAPHYLINUS. 885 
occupying two thirds of the length of the sides. Thorax quadrate, quite dull, very 
densely, rather coarsely, punctate, with a very short shining line in front of the 
scutellum. Elytra as long as the thorax. Hind body with a rather faint mark of 
whitish pubescence at the middle of the base of each segment—this mark is rendered 
more conspicuous by the tomentum on each side of it being blacker and more dense ; 
the sixth segment has at its hind margin a short, irregular, transverse, faint pallid fascia, 
and the terminal segment has at the extreme base a flammulate fascia extending all 
across it; the lateral portions of the anterior segments are also obscurely variegate with 
sparing griseous atoms. | 
Mr. Flohr has sent a pair of this species; the male has a deep broad excision on the 
terminal ventral plate, and there is a depression along the margins of the excision; the 
preceding segment also is broadly and conspicuously emarginate, and somewhat depressed 
in front of the emargination, and the middle portions of these two segments are more 
densely and finely punctate and more pubescent. 
This insect is about the size of S. tomentosus, but is readily distinguished by the 
different eyes and more variegate hind body.

America! 2, widely distributed. 
This is the most abundant and most variable of the Tropical-American species of the 
genus. In our region it shows much variation. I have not observed any examples 
agreeing exactly with the variety from Para described as the type of the species by 
Nordman; but an example from Chontales in my collection approaches in most respects 
thereto, but has the antenne entirely ferruginous; the examples from Bugaba differ 
but little from Colombian specimens. The species apparently is very common in 
Mexico, where also it varies a good deal, many examples having the hind body but 
little variegate, and dark even at the extremity.
