46 Mr. G. R. Waterhouse's Descriptions of 



moderate. Thorax short, cordate ; the lateral foveas behind, 

 large, the central one small ; the transverse groove deep ; the 

 discoidal fovea oblong and small ; the surface very finely, and by 

 no means thickly punctured. Elytra rather paler than other 

 parts ; shorter than the head and thorax taken together ; the 

 sutural stria moderately impressed, and the stria about midway 

 between this and the humeral hump, very short, not extending 

 beyond the basal third of the elytra; the surface with scarcely 

 any visible punctuation, even under a very strong lens. Abdomen 

 broad and subdepressed ; the two first (of the visible) segments 

 each with a depressed area at the base in the middle, and this 

 area bounded on each side by a slender groove; the two grooves 

 diverging posteriorly. 



Length 1 hne. 



1 can perceive no distinctions indicative of sex in the only two 

 specimens which have come under my notice. Both of these were 

 found by me in Kent, one at Greenhithe and the other in Darent 

 wood; tiie latter, in the sawdust of a recently felled oak. 



This insect is readily distinguished from the following species 

 by its superior size, combined with a rufo-testaceous colouring, 

 the large size of the head, and its more depressed form. It seems 

 to agree very well with M. Aube's description o? E. Kiinzei, but 

 in that description the comparatively large size of the head is not 

 noticed, and hence some doubt may arise with respect to this 

 identification. 



2. Euplectus Denni'i. 

 Evpl. sanguineus, Denny, Monographia Pselaphidarum, &:c., p. 10, 

 sp. 2. 18^5? 

 Elongate, pitchy-black, glossy, and almost impunctate. Head 

 gradually rounded and contracted behind the eye, which is rather 

 large; the two anterior foveae decidedly more widely separated than 

 the posterior, and united by a strong transverse groove ; they are 

 likewise united with the posterior foveas by two longitudinal 

 grooves, and these diverge slightly as they approach the fore part 

 of the head ; * the area immediately above the eye, and the raised 

 mesial area behind, are punctured ; there is no distinct fovea 

 on this raised part, but frequently a small depression at the 

 back. Thorax about equal in length and width, distinctly 

 contracted before and behind ; the broadest part towards the 



* I may here remark, that the posterior foveae are only distinct when the head 

 of the insect is away from the observer. When viewed (as is my usual custom in 

 examining Coleoplera) with the head in the opposite direction, they appear to be 

 confounded with the longitudinal grooves which unite them with anterior foveffi.
