Ovate, black, shining, thickly and minutely punctured, pubescent ; 

 thorax usually with three white pubescent spots at the base, one at 

 each angle, the other in the middle ; elytra somewhat piceous or 

 slightly castaneous, with a white pubescent spot on the back of each 

 wine-case near the suture. The under side piceous-black, clothed with 

 yellowish pubescence; legs dark, with a reddish tinge. The color is 

 somewhat variable, being often paler than above described. Length, 

 one-sixth of an inch. The larva- feed on dry skins, furs, woolens, etc. 



anthrenus mus^eorum — Linn. (A. castan.e — Walsh.) 



Very small ; and similar in form to the preceding. 



Color a dull black, irrorated with feruginous scales; thorax with 

 the disk sparingly dusted with testaceous scales, the posterior angles 

 and central area densely clothed with whitish ones. Elytra with 

 three bands composed of whitish and lutescent scales, the basal one 

 arising at the base of the elytra, passing down the sides of the scutel- 

 lum, and bending outwards, when it becomes rather obsolete and ir- 

 regularly flexuous; the second is a little behind the middle, transverse 

 and flexuous ; the third, which is near the apex, is rather oblique, 

 and frequently united to the second on the suture or on the margin. 

 The body beneath is cinereous, with naked marginal spots ; femora 

 black ; tibia? and tarsi rufescent; antenna? ferruginous with the club 

 obscure. Variable in size and in the appearance of the bands on the 

 elytra. Length about one-tenth of an inch. 



As this is chiefly injurious in museums and cabinets of natural 

 history, I have given the full description, as found in Stephens. 



Family TROGASITID^E. 



The family characters are given in the description of the following 

 species : 



tenebrioides (Trogosita) mauritanica— Linn. 



Oblong, rather elongate, somewhat depressed; antennae short, with 

 the three last joints enlarged ; tarsi apparently four jointed, the first 

 joint being so short that it is invisible from above, last joint very 

 long; abdomen pedunculated. 



An obscure black head and thorax marked with gross scattered 

 punctures; thorax with a dorsal line, sides simeate, anterior and pos- 

 terior margins nearly straight, broader at the former than the latter, 

 posterior angles slightly acute. Elytra striate, with punctures, the 

 intervening ridges slightly convex. Abdomen and front breast 

 sparsely punctured. Antenna? and feet reddish. Length nearly two- 

 fifths of an inch : width of elytra and thorax about one-third the 

 length. *■ 



It has long been supposed this species injured grain stored in grain- 

 eries ; but it is now believed it preys upon grain-eating larva?. 



LUCANIDTE. (Stag-Beetles or tTorn-Bugs.) 



This family includes those species which have received in different 

 localities the various names of stag-beetles, horn-bugs, pinching-bugs,
