distinct from other members of the bicostate group, though (very 

 superticiall}') nearest to H. ellipticus Lea. It is, however, 

 narrower, in proportion to lengtli, than H. ellipticus, while its 

 detailed structure is very different. The prothoracic margins 

 take a wide sweep forward, and the long, sparse, pale yellow 

 hairs above, and the thicker and darker clothing beneath, make 

 this species easily identifiable. 



Hel^eus Georgei, n.sp. 



Widely ovate, rather depressed, dark brown, moderately nitid, 

 with edges, costae, oral organs, and tarsi reddish, antennae and 

 tibiae pitchy-red. 



Head narrowly rounded in front, with epistoma reflexed and 

 limited behind by a straight transverse suture, forehead flat, 

 minutely pustulate, eyes approximate; antennae extending beyond 

 base of prothorax, third joint as long as fourth and fifth com- 

 bined, 8-iO round, eleventh wider and longer than preceding, 

 ovoid. Prothorax 4x10 mm., width at base, length in middle, 

 flat and depressed on disc, margins widely perfoliate, together 

 half as wide again as disc, nearly semicircular in outline, faintly 

 sinuate towards apex, base bisinuate, anterior processes over- 

 lapping, narrowing but rounded at apex, posterior angles acute 

 and produced backward, extreme margins strongly raised, outside 

 edge (seen sideways) concave; foliate margins increasingly concave 

 towards apex, disc minutely punctate, pustulate and clothed with 

 very short reddisli hair (very sparsely so on margins); base and 

 apex with thin, raised, reddish border, disc with central carina 

 bicurved, little raised, and not continuous to base or apex. 

 Scutellum raised, strongly transverse and elliptic. Elytra much 

 wider than prothorax, widest at middle, foliate margins wide and 

 slightly undulate, their planes a little inclined upwards, very 

 little narrowed at apex, faintly punctulate; exti'eme edge (seen 

 sideways) concave, slightly wider than that of prothorax, forming 

 a reflected margin subobsolete at apex; disc with two sharp sub- 

 parallel costae strongly raised, slightly divergent at base, abruptly 

 ending on apical declivity and narrowly separated (about 2 mm.);
