380 A. EK. Verrill—The Bermuda Islands. 792 
The specimen figured (fig. 165) has a dull brownish black surface ; 
clypeus broadly rounded and not bidentate in front ; head scarcely 
sculptured ; tibie of fore legs with three short, not very stout, 
denticles and a spur; prothorax not very convex. Another speci- 
men, probably ‘the male, has a black and very glossy surface, with 
the same sculpture ; clypeus bidentate in front ; head rougher; fore. 
legs stouter, with broader tibie, bearing 3 strong denticles and a 
sharp spur. October, L. Mowbray. Identified by Mr. Schwarz. 
This species seems to have nearly the same habits as ZL. gibbosus, 
from which it is not distinguished by the inhabitants. 
Psanmodius, sp., t. Schwarz. 
A small black scarabzid occurs, resembling the ‘ Hard-back” in 
form, and with the anterior tibiz flat and three-toothed. Elytra 
strongly sulcate ; prothorax strongly convex, slightly glossy, very 
minutely punctate. Length 4™™. Oct., L. Mowbray. 
Dung-beetles. (Aphodius, etc.) 
Several species of these beetles occur; among them, Aphodius 
ruricola Melsh. and A. jfimetarius (L.) Hlig. The latter is a small 
beetle, easily recognized by its bright red elytra and black head and 
thorax. It is also very common in New England in early spring. 
Hide-beetles ; Skin-beetles. (Trox scaber L. and T. suberosus Fab.) 
Plate xcix; figures 11, 12. 
Both of these are recorded by J. M. Jones, 1876. They feed on 
dead animal substances of various kinds, including hides, and are 
widely distributed in North America. The first is brownish black 
with clearly black ribs and tubercles ; length 7™™; the second is dull 
dark brown, with black tubercles, and brownish yellow specks ; 
length 15™™. 
Ptinids. Spider-beetles. (Ptinus fur L.) Figure 166. The larva 
of this small beetle is often destructive to dried animal substances, 
such as furs and skins, woolens, museum specimens, books, etc. ; it 
sometimes feeds, also, on flour, cotton seed, red pepper, etc. It is 
widely diffused in most countries. The color of the beetle is reddish 
brown; the elytra are crossed by four white bars; the long legs 
and antenne give it a spider-like appearance. An allied plain brown 
species (P. brunneus), having nearly the same habits, is also likely 
to occur, but was not seen by us.
