glossy. Prothorax rather widest behind, with the basilar angles somewhat 

 depressed : scutellum transverse, obtusangular : shoulders of the elytra 

 obscurely rufous : legs, especially the tibiae and tarsi, pale chestnut.

 A single specimen taken in Lat. 54^ 



[113,] In shape, sculpture and pubescence this species resembles the 

 preceding, but it is smaller, and the whole insect is entirely of one colour 

 --^rk ferruginous. 



N. B. — The two species last described differ from the other Crypto- 

 p^hagi in having the thorax without serratures or denticles, and the scutel- 

 lum obtusangular, and may perhaps forni a subgenus.

161. Attagenus cylindricus Kirby. Plate vii., fig. 3. — Length of 

 body 2 lines. Two specimens taken in the Rocky Mountains. 



This little species has much the air of a Cryptophagus, but belongs to 

 the present genus. The body is subcylindrical, dark-piceous, very minutely 

 punctured, and covered, but not thickly, with decumbent cinereous hairs. 

 The two first joints of the antennae are large, globular, and of the same 

 colour with the rest of the body ; the intermediate ones very minute and 

 pale rufous ; the three last are incrassated and form an oblong piceous 

 knob, of which the terminal joint is as long as the two preceding ones, 

 ovate and acute : the prothorax behind is very obsoletely trilobed with 

 the intermediate lobe rounded : the tarsi are rufous. [L'nknown to Dr. 

 Le Conte.]

This species, though particularly destructive to furs, is to be met with 

 in other animal matters, and is very common in houses. De Geer 

 describes its larva as having a very long bcdy covered with a hard, shining 

 skin of a reddish-brcwn colour and hairy ; as havijig six legs, and the 

 posterior extremity terminated by a long remarkable tail, formed of rufous 

 hairs as long as the body, and placed horizontally in ♦he same line. He 

 says that their motion is gliding, but by snatches. 



The American specimen, which is a male, is considerably larger than 

 ray British ones and blacker ; but in other respects it precisely resembles 

 them. The species may generally be known by its black or dark-piceous 

 solour, covered, especially underneath, with decumbent whitish or ciner- 

 eous hairs. The stalk of the antennae, and the tarsi, are testaceous, and 

 the Ust joint of the former, in the male, is longer than the two first and
