796 A. E. Verritt — The Bermuda Islands. 



Tapestry-beetle (Attagenus piceus 01.), fig. ITS, often destructive to 

 carpets and rugs. The last named feeds also on all kinds of dried 

 animal substances, even including leather, wool, silk bolting cloth, 

 feathers, etc., and not infrequently attacks flour, meal, grain and 

 various seeds and drugs, including red pepper. 



Probably Trogoderma tarsale Melsh., another related, common, 

 omnivorous beetle also occurs, though we secured no specimens. 

 Like the last, it eats all sorts of dried animal substances and occasion- 

 ally feeds on meal, grain, corn, peanut cake, oil seeds, etc. 



Hlsterids. — One species of this family was obtained. 



Epurma luteola Ev. (t. Schwarz), family Nitidulidce, a small cos- 

 motropical species, found also in Florida and Texas, was sent by L. 

 Mowbray. 



Coccinellids ; Lady-bugs • Aphis-wolves / Squash-beetle. 



Larvre of one species were observed devouring aphids.* 

 Dr. Fr. Dahl (Plankton Exped., i, pt. 1, p. 108) also records a 

 species of Coccinella. 



Staphyllnids ; Move-beetles. 



Several species of Rove-beetles were found, but are mostty unde- 

 termined. One of the most abundant under dead fishes on the 

 shores was a very small black species. 



The largest is Creophilxs villosus Kirby, an American species, 

 about .5 to .75 of an inch long, glossy black, with patches of fine 

 gray hairs, a band of which crosses the elytra ; another crosses the 

 second and third abdominal segments. 



Dytiscids ; Water-beetles. 



This family is represented by at least one North American species 

 (Thermonectes omaticollis Aube=7I irroratus Melsh., t. Lee, Cat.). 

 The* thorax is fulvous, with two transverse blue lines. Length, ] L ; '" m . 

 Its aquatic carnivorous larva? devour the larvae of mosquitoes and 

 other insects. Other related species, which are numerous in the 

 United States, could easily be introduced and would be very useful. 



* It would, doubtless, be very easy and very advantageous to introduce many 

 additional species of Lady-bugs from the United States and West Indies to 

 destroy the numerous Aphids and Scale-Insects found here. This has been done 

 in California, with admirable results, as in the case of Vedalia cardinalis, intro- 

 duced from Australia to destroy Icerya Purchasi. See p. 804.
