Mr. A. Murray^s Monograph of the genus Catops. 21 



mentions it as having been taken in the south-west of Siberia. 

 The whole of the above varieties are found in England and Scot- 

 land, but var. D is the commonest and var. A the rarest — (of it 

 I have only seen one example).

Oblongus, nigro-piceus ; thorace fortius punctata,

The most robust species in this group. Head, thorax and 

 under-side in the fully-coloured individuals pitchy black, the 

 elytra fine chestnut-brown. The examples not fully coloured are 

 dirty yellowish brown. The antennae are tolerably long, scarcely 

 half as long as the body, reddish brown, in the normal state the 

 last five joints darker; the first somewhat stronger, third some- 

 what longer than the adjoining joints ; second, fourth and fifth of 

 equal length ; sixth somewhat shorter than the fifth, and as long 

 as the seventh and ninth ; eighth somewhat shorter than the 

 tenth ; tenth somewhat shorter than the ninth ; the last joint is 

 somewhat shorter than the foregoing, strongly acuminate. The 

 head is pitchy black, the parts of the mouth ferruginous red ; 

 the top of the head finely and sparingly, the front more deeply 

 and strongly punctured. The thorax is distinctly narrower 

 than the elytra, a little arched, somewhat broader than long; the 

 sides rounded, and somewhat more so in front than behind, 

 so that the greatest breadth of the thorax is rather before the 

 middle ; the posterior angles are obtuse and rounded off, the 

 basal margin straight-truncate ; the margin in the posterior half 

 is broadly expanded and a little bent up, so that a somewhat 

 bent and deep line arises on each side, particularly when seen 

 from above. The upper side is strongly and deeply punctate*, mo- 

 derately densely covered with a golden-yellow pubescence, with 

 a distinctly impressed line along the middle, about one-third of 



* Sturm says, " finely and densely" punctate, but Kraatz projierly cor- 

 rects this ; the deep coarse punctuation bcinj; one of tlic most characteiistr' 

 features of the species.
