384 A. FE. Verrill—The Bermuda Islands. 796 
Tapestry-beetle (Attagenus piceus Ol.), fig. 173, 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, ete., 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 oceasion- 
ally feeds on meal, grain, corn, peanut cake, oil seeds, ete. 
Histerids.—One species of this family was obtained. 
Epurea tuteola Ky. (t. Schwarz), family Witidulide, a small cos- 
motropical species, found also in Florida and Texas, was sent by L. 
Mowbray. 
Coccinellids ; Lady-bugs ; Aphis-wolves ; Squash-beetle. 
Larvze of one species were observed devouring aphids.* 
Dr. Fr. Dahl (Plankton Exped., i, pt. 1, p. 108) also records a 
species of Coccinella. 
Staphylinids ; Rove-beetles. 
Several species of Rove-beetles were found, but are mostly unde- 
termined. One of the most abundant under dead fishes on the 
shores was a very small black species. 
The largest is Creophilus 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 ornaticollis Aubé= T. irroratus Melsh., t. Lec., Cat.). 
The thorax is fulvous, with two transverse blue lines. Length, 12™™. 
Its aquatic carnivorous larve devour the larve 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.
