118 COLEOrTERA. 



loi]g brov/n pubescence and wide sub-quadrate shape, and 

 from the latter by its want of erect setae. Besides these 

 differences it appears to be distinguished by its large size, 

 sub-seneous colour, long legs and antennae (the latter being 

 entirely pale yellow), and the sculpture of its prothorax, 

 which is strongly tuberculate, with the interstices faintly 

 alutaceous. 



Mr. Matthews states that it may be found in the summer, 

 not uncommonly, in heaps of dead leaves. 



99. Trichopteryx bovina, Motsch. Bull, de Mosc. 1845 ; 



Rev. A. Matthews, Ent. Monthly Mag. vol. i. p. 174. 



Mr. Matthews states that this species differs from T. seri- 

 cans, with which it is usually associated, in its deep black 

 colour, ovate shape, and much shorter antennae ; also in the 

 peculiar sculpture of its prothorax, which is covered with 

 small distinct tubercles disposed in wavy rows, with the in- 

 terstices distinctly and elegantly alutaceous. 



It appears to be common, and found (as its name implies) 

 beneath cow-dung, though seldom met with elsewhere. 



It is needless for me to add that the compound microscope 

 is required to " bring out" sculpture in these minute insects. 



100. Trichopteryx picicornis, Mann. Bull. Mosc, 43, 



84 ; Rev. A. Matthews, Ent. M. Mag. vol. i. p. 175. 



Mr. Matthews remarks that this species (by no means 

 rare) is also usually included under the name of T. sericans; 

 and that it is easily distinguished from all its congeners by 

 its oblong, parallel, and depressed shape, long legs and 

 antennse, the dilated joints of its four anterior tarsi, and the 

 sculpture of its prothorax, which is not tuberculate, but 

 simply alutaceous.
