and covered with short wholly black hairs. Thorax 

 lemon-yellow above, descending partially down the sides 

 in front of the fore wings; there is a short lozenge- 

 shaped black space, lying partly on the hinder edge of the 

 meso-scutum and the anterior half of the scutellum, 

 while the hinder convex edge of this last piece is rather 

 broadly margined with yellow. The two basal rings of the 

 abdomen and half of the third are black, while the side of 

 the third is yellow ; fifth ring black above, yellow on the 

 sides ; tip naked, large, triangular, incurved, with an oval 

 depression on the upper side ; beneath, the body is wholly 

 black. Legs stout, short, black : tips of the tibiae fuscous ; 

 the inside of the first tarsal joint partially, or in certain 

 lights, wholly deep fuscous ; remaining joints dark fus- 

 cous ; the fifth one including the claws darker than the 

 others. The wings are a little paler than in A. elatus, 

 with black veins. Length, .75 ; breadth, .35 ; expanse of 

 wings, 1.45 inches. 



I have taken several female specimens of this handsome 

 species during the middle and last of summer, at 

 Brunswick, Me. There is one specimen, " No. 215," not 

 labelled, in the Harris collection belonging to the Boston 

 Society of Natural History, which, as nothing to the 

 contrary is stated, must have been captured near Boston. 



In size and form and partially in its colors it is similar 

 to B.fervidus, and is perhaps a parasite upon it. 



APATHUS CONTIGUUS Cresson. 



Male. Front black ; vertex yellow ; thorax and two 

 basal joints of the abdomen yellow ; body beneath, and the 

 five terminal joints of the abdomen black. Legs black ; 

 tarsi fuscous, the basal joint blackish except on the edges. 



It very closely resembles B. vagans Smith, differing from 

 it by the nearly twice as broad front, which is black 

 instead of yellow, as in B. vagans, and the body is entirely 

 black beneath, where B. vagans has long yellow hairs. 

 Length, .67 ; breadth, .28 inch. (Mus. Comp. Zool., Mr. 

 Norton.) 



APATHUS CITRINDS Smith. 



Male. Front black, a few greyish-yellow hairs on the
