long as 10. Prothorax 3| x 8 mm., arcuate-em arginate at 

 apex ; anterior angles advanced but widely rounded, sides, 

 arcuately widened to base, posterior angles acute and very 

 slightly produced; base bisinuate, explanate margins wide and 

 concave, extreme border narrowly raised on sides and apex ; 

 disc very convex, closely and clearly punctate; medial line 

 rather deeply impressed and terminating apically in a tri- 

 angular depression ; two large and, deeply-impressed basal 

 foveae, and two more irregular foveas at the anterior corners. 

 Scutellum transverse, curvilinear triangular, raised in middle, 

 foveate on each side. Elytra ovate, very convex, wider than 

 prothorax at base, humeral angle obtuse, horizontal margins 

 wide for the greater part, rather abruptly narrowed towards 

 apex ; disc very gibbous in humeral region ; each elytron with 

 seventeen rows, besides a short scutellary row T , of large round 

 punctures, closely placed, the lateral row larger than the rest, 

 the punctures becoming smaller towards suture and apex, also 

 some confused punctures at base ; all intervals slightly convex, 

 the fifth and ninth wider than the rest, the former costate on 

 the basal two-thirds; epipleurae very concave, with a crenulate 

 sulcus running throughout its middle. Abdomen strongly stri- 

 gose-punctate; metasternum finely punctate; prosternum 

 rugose. Dimensions — 15-16x9-10 mm.

.Two specimens, the sexes, under examination. The strong 

 convexity, colour, and bloom on a fresh specimen gives it the 

 superficial appearance of Encara nigrum, Cart. It belongs to 

 sect, ii., sub-sect, iii., of my table (near sternalis, Cart., con- 

 fusuSj Macl.), and can be distinguished from its allies by the 

 following combination: — (1) Colour (when the bloom is re- 

 moved) nitid dark-brown with a reddish tinge ; (2) great con- 

 vexity ; (3) crowded state of the punctures both longitudinally 

 and transversely, with the comparatively large size of the indi- 

 vidual punctures (between four punctures in two adjacent 

 series there would be only room for a single puncture) ; (4) the 

 convexitv of the interstices and the marked width and con- 

 vexity of the fifth interval ; (5) nonpustulose metasternum. 



Pterohel.eus cylindricus, n. sp. 



Elongate-parallel, very convex laterally; black, moderately 

 nitid; antennae and tarsi red; tarsi and tibiae thickly clothed 

 with golden tomentum. 



Bead— Epistoma wide, rounded and reflexed in front and 

 sides, its curve continuous with the canthus, its suture only 

 indicated by oblique lines at the sides ; sparsely punctate ; eyes- 

 separated by a distance less than the diameter of one ; antennae
