792 A. E. Verrill — The Bermuda Islands. 



The specimen figured (fig. 165) has a dull brownish black surface ; 

 clypeus broadly rounded and not bidentate in front ; head scarcely 

 sculptured ; tibia? 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 tibiae, 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 L. gibbosus, 

 from which it is not distinguished by the inhabitants. 



Psammodius, sp., t. Schwarz. 



A small black scarabaeid occurs, resembling the " Hard-back " in 

 form, and with the anterior tibiae flat and three-toothed. Elytra 

 strongly sulcate ; prothorax strongly convex, slightly glossy, very 

 minutely punctate. Length 4 mm . Oct., L. Mowbray. 



Dung-beetles. {Aphodius, etc.) 



Several species of these beetles occur ; among them, Aphodius 

 ruricola Melsh. and A. fimetarlus (L.) Illig. 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 scaler 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 mm ; the second is dull 

 dark brown, with black tubercles, and brownish yellow specks ; 

 length 15 mm . 



Ptinids. Spider-beetles. (Ptinusfur 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 antennae 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.
