Gen. ANTHRENUS, Lat. Byrrhus, Lin. 



Antennae short, with a solid club, and lodged in a lateral furrow 

 of the thorax ; mandibles small, or not projecting ; pre-ster- 

 num dilated at its anterior extremity ; body ovoid ; feet con- 

 tractile ; tarsi with five joints. 



This genus is commonly found on flowers. They draw up their feet when taken, 

 and preserve this position when dead. 



A. scrophularice, Lat. Deep black, with the suture of the elytra 

 reddish, and three gray bands. Inhabits Europe, on plants. 

 Lat. Hist. ix. pi. 79, fig. 1. 



A.fascus, Lat. Body subovate, obscure brown ; antennae and feet 

 red. The larva of this species is one of the greatest destructors 

 in museums. Inhabits Europe, in museums Lat. Gen. ii. 39. 



Gen. NOSODENDRON, Lat. Sphteridium, Fab. 

 Body ovoid, convex ; head inclined ; antennae short, thickest 

 towards the end, concealed in repose under the sides of the 

 thorax, with the last three joints forming an ovoid perfoliated 

 club ; palpi short, equal and cylindrical ; chin large ; head 

 triangular ; legs large, triangular, and dentated.

 hairs on the elytra. 2 lines long. Found near Paris. Lat. 

 Gen. ii. 44. 



Gen. CHELOSARIUM, Fab. 



Head concealed under the thorax, semicircular ; antennae mo-

 third joints very large, compressed, and the following short.

 West Indian Islands Lat. Gen. i. pi. 8, fig. 7. 



Gen. BYRRHUS, Lin. Lat. Dermestes, De Geer. 

 Body ovate ; head concealed ; antennae short, straight, terminat- 

 ing in a perfoliated club ; feet compressed, with the tarsi com- 

 posed of five filiform joints ; no furrows for the antennae.

 gitudinal lighter stripes, interrupted by blackish spots. Inhabits 

 Europe, in fields, by road sides, &c. Shaw, vi. pi. 13. 



The genera Limnkhus and AsphUophorus have been separated from this group. 



TRIBE VI. MACRODACTYLI. 



The insects of this tribe are found in the water or on the banks of marshes or ri- 

 vulets. Many have but four joints in the tarsi, the first very small. The fore part 

 of the sternum is always dilated into a kind of chin, and receives the inferior por- 

 tion of the mouth or conceals it. The antennas of some have six or seven joints ; in 

 others there are ten or twelve ; the whole scarcely longer than the head, and termi- 

 nating in a fusiform or cylindrical club, more or less dentated, commencing at the 

 third joint ; and some have the antennae filiform and the length of the head and tho- 

 rax. The tarsi are generally terminated by a broad joint with two hooks.
