Rhys, europaus. Ahrens ; ' Fauna Ins. Eur.' fasc. vi. fig. 1. 



Colour pitchy black, sometimes, probably when immature, inclining to 

 ferruginous; the head is somewhat triangular, with the posterior angles 

 rounded, on the crown are two deep fovea, from each of which issues a far- 

 row, anteriorly towards the clypeus, and posteriorly to the extreme margin 

 of the head; the vertical portion of the head is thus divided into three raised 

 glabrous masses; of these the lateral ones are reniform; immediately adjoin- 

 ing the clypeus is another small and abbreviated longitudinal furrow ; the 

 eyes are distant, lateral, somewhat oval, and but little prominent; the pro- 

 thorax is narrower anteriorly, convex laterally, and narrower again before 

 the posterior margin, which is quadrate, truncate, and has the angles very 

 slightly produced ; the lateral margins have a distinct ridge, and the dor- 

 sal surface has three deep longitudinal furrows ; of these the central one ex- 

 tends nearly to the anterior, and quite to the posterior margin, at both ends 

 it is rather dilated ; the lateral furrows reach the posterior margin, where 

 they are much dilated, but they cease considerably before the anterior mar- 

 gin ; the furrows are deeply punctured, but the interstices are smooth : the 

 elytra have seven regularly punctured strice, five of them dorsal and two la- 

 teral : the protibice have a tooth a little before their apex, curved forwards, 

 and at the apex two others, curved downwards. 



Inhabits the continent of Europe. — Sweden, Hungary, Ger- 

 many, France, the Pyrenees, &c.

Sp. 4. Rhys, liratus. Piceo-niger, squamosus ; caput elongatum, ova- 

 tum, vertice bisulcatnm, angulis posticis rotundatum : oculi distincti, 

 distanti, fere rotundati ; prothorax profunde trisulcatus; elytra trisul- 

 cata, sulcis punctatis. (Corp. long. .3 unc. lat. .06 unc.) 



Colour pitchy black, but covered in the depressed parts with a grey pilo- 

 sity, resembling scales, a character possessed in a less degree by all the spe- 

 cies of the genus : the head is more elongate, oval, and narrow than in either 

 of the species I have described ; the vertical portion consists of three ele- 

 vated glabrous longitudinal ridges, and of two deep furrows which serve to 

 separate them ; the central ridge ceases posteriorly before the union of the 

 head with the prothorax, and the furrows consequently unite at this point; 

 the lateral ridges extend to the base of the antennce ; exterior to each late- 

 ral ridge is a small but distinct and bright reniform eye, which projects but 

 little from the lateral surface of the head, and is situated about midway be- 

 tween the base of the antennce and the posterior margin of the head : the 

 prothorax is elongate, oval, and nearly of equal width at both extremities, 

 it has four glabrous longitudinal ridges dorsally, and two minor ones on 

 each side the dorsal ridge are separated by three deep equidistant furrows ; 

 of these the central one is dilated anteriorly, the lateral ones posteriorly, 

 none of them quite reach the anterior or posterior margins ; the elytra have 

 the scutellar region deeply impressed, each has four distinct ridges ; near 

 the suture is a distinct but slightly impressed stria, then follows a conspi- 

 cuous ridge, which ceases anteriorly in the scutellar depression, and poste-
