on furs, the hair of which then comes out in patches ; and also 

 in stuffed animals and in natural history collections. 



Genus Anthrenus, Fabr. 

 Numerous small, rotund or shortly oval beetles, usually with 

 eleven joints to the antennas and with laterally-curved elytra, 

 which are variously marked with white and yellow scales. The 

 pronotum is expanded behind into a lobe. They live on animal 

 substances, but are also found in large numbers on flowers. 



* A. scrophularicc, Linn. (Plate YL, Fig. 26). Antennae eleven- 

 jointed; wing-cases with a red suture and extremity, and 

 with three bands. This sj)ecies is found on flowers, preferring 

 TJmbdlifcrce ; but is also common on furs and in collections of 

 insects, on the Continent, but is very rare with us. 



* A. pi'i^ipinellcc, Fabr. (Plate VI., Fig. 27). Black above, 

 varied with red and white. The elytra with a broad white 

 band, and two spots of the same colour at the extremity. 

 It is also common on Howers, and swarms in old birds' nests 

 on the Continent, but is very rare in Britain. 



* A. museorum, Linn., the Museum Beetle (Plate VI., Fig. 28). 

 Antenna with eioht segments, the club bein^^ formed of two. 

 It is blackish -brown, sprinkled with rusty -brown. The 

 wing-cases are clothed with grey and orange scales. It is 

 common on flowers in ]\Iay, and the larv?e are very destructive 

 to collections, especially to those of insects, &c. The best 

 remedy against these and against mites, is to supply the boxes 

 or cabinet-draw^ers with naphthaline.
