1 14 Mr. A. MniTay*s Monogritph of the germs Catops. 



This species is widely spread, and is found under leaves, and 

 under the carcases of birds and small nuuniuals.

Of the same size and general form as the last 

 species {nir/rita, Erichs.) ; the thora.v, however, 

 is not so broad, particularly behind. Perhaps 

 the commonest impression it makes on a first 

 introduction is that of an insect with longish elytra and a dis- 

 proportionately short, narrow, somewhat square thorax. The 

 antennfe are nearly a.s long as the head aud thorax, strongly 

 thickened towards the ])oint ; the first six joints slender, reddish 

 brown, those following brown, broader than long, the eighth 

 not only much shorter but also narrower than the remainder of 

 the club, the last a little larger than the preceding, with a cone- 

 shaped point, generally pale at the tipf. The head and thorax 

 are black, densely punctate, more or less wrinkled transversely, 

 and thickly covered luith a close yellow pubescence ; the hairs 

 springing from the wrinkled ])unctuation as shown in the

magnified sketch represented in fig. 15. 

 The thorax one-half broader than long, 

 rounded on the sides, broadest in the 

 middle, or perhaps rather a little before 

 the middle, giving the primd-facie effect 

 of being narrowest behind ; but on com- 

 paring the narrcnvness both in front and 

 behind it is found nearly equal, or rather 



narrower before than behind. The posterior angles are sharplj^ 

 right-angled, the straight edge proceeding a little forward before 



* As already mentioned, I have been nnable to make out satisfactorily 

 what the trisfis of Spence is, and therefore have not added that as a syn- 

 onym here. 



t Eriehson says that the last joint is brown like the preceding, but this 

 IS only the case sometimes ; generally speakuig it is jjaler.
