the anterior angles, gradually widened, sinuate and reflexed to the 

 hinder angles, which are rounded ; hinder side margins less reflexed, 

 gradually narrower to the posterior angles, which are rounded ; 

 posterior margin nearly straight, but little produced at the ends ; 

 disk finely transverse-crenate, in front, towards the sides depressed, 

 posteriorly transversely-convex ; keels thick, not deep, the two 

 middle ones rather closer to each other than to the side keels, as 

 long as the pronotum, slightly divergent and shallower posteriorly ; 

 the side keels much abbreviated in front ; between the keels deep 

 furrows ; the callosity at the posterior angles large, prominent. 

 Scutellum long, narrow, concave, the base raised, side margins much 

 raised and recurved, apex obtuse. Elytra ; Corium, the foliaceous 

 enlargement of the anterior margin reflexed, not very wide, gradually 

 narrower; nerves and reticulations of the disk strong. Sternum 

 with a small yellow spot at the base of the coxa3. Legs; ihiglis 

 black ; tibia and tarsi black-brown. 



Abdomen; in the ? beneath, the 6th abdominal segment is 

 visible only in the conuexivum, the intervening transverse space 

 being occupied by the 1st of the visible genital segments, which is 

 quadrangular and very convex ; the 2nd visible genital segment is 

 very convex, posteriorly rounded, then suddenly deflected to the 

 horizontal foliaceous margin, of which the two lobes are broad and 

 regularly rounded, the posterior notch between them small and 

 angular, and the cleft extended as a ridge up the convex end of 

 the basal part of the segment. In the $ , the foliaceous margin of 

 the last genital segment is not so much rounded on the sides as in 

 the $ . Connexivum with a deep yellow, angular spot at the pos- 

 terior outer angle of each segment ; 6th segment long, rounded 

 posteriorly; beneath, a small round yellow tubercle near the 

 anterior inner angle of each segment, and the yellow spot at the 

 posterior angle showing through from the upper side. 



Length, 2f lines. 



Rare ; one specimen, $ , taken at Darenth Wood, among chips on 

 the stump of a felled oak, 30th May, 1861 {Douglas) ; another
