68 THE ENTOMOLOGIST S RECORD. 



The following is a translation of Ganglbauer's description of this 

 insect {Kdfcr v. Mitteleuropa, vol. iii., p. 182): — 



Closely related to ingricavs, but differs from it by its much smaller size, much 

 less convex form, and shorter antennre, which are nearly always blackish towards 

 apex, and whose eighth joint is much shorter in both sexes, being transverse even 

 in the j . The posterior angles of the thorax are less produced posteriorly, and 

 the base of the thorax is more weakly sinuate on each side. The elytra are flatter. 

 The anterior tibite of the <? have a much more distinct hump-like dilatation in 

 the middle of their inner sides. Very closely resembles specimens of Hi(/r/fa, in 

 which the apical joint of the antennae is not lighter, and differs from these only 

 by the somewhat acutely produced posterior angles of the thorax, by the presence 

 of faint longitudinal stria- on the anterior half of the elytra, and by the hump-like 

 dilatation on the middle of the inner sides of the anterior tibiffi of the d' . 

 Length, 3-5mm.-4-5mm. 



I took five specimens of this insect (two 3 s and three ? s) at 

 Alphington, Devon, from under dead leaves in a small plantation, in 

 company with ('. fiisca, C. tristis, and C kirhi/i. Mr. Dollman has a 

 series from the Harrow district from moles' nests, and Mr. Donisthorpe 

 a specimen from Hartlepool out of carrion. There are also several 

 specimens in the Bates' collection standing under nifiricans and 

 niiirita. It is probably a fairly widely distributed species in this 

 country. Captain Deville says it is common in France, and the types 

 he has kindly sent were taken in rabbit-burrows. 



As the subgenus, PtoinapluKjnR, Hellwig, or, as it is now called in 

 the European catalogue, the genus Catops, Th., is considered by 

 English coleopterists to be a very difficult one, I venture to give a 

 translation of Ganglbauer's table, in-so-far as it deals with the British 

 species, since 1 was surprised at the ease with which I could name all 

 my specimens by its aid.
