of pi'Othorax at base, gradually narrowing to apex, but flatter 

 than in //. Gilesii, extreme borders subvertical or slightly out- 

 wardly oljlique, with edge (seen sideways) concave, wider than 

 the edge of ))rothorax and perceptibly wider than in H. 

 GiUsii, especially near apex. Disc very convex, finely and more 

 closely punctured, with no indication of a linetir arraiige- 

 ment except by two faint lines of larger punctures equally and 

 widely separated; the punctures bearing short black bristles; 

 three strongly raised costte arranged as in H. Gilesii; discal 

 costte 4 mm. apart, the junction of margins with disc also indi- 

 cated by a slightly raised interrupted costa, outside which is a 

 row of large lateral punctures (much larger than any on //. 

 Gilesii). Abdomen very minutely and densely punctate, under 

 side of margins with larger punctures (in botli cases finer than 

 in //. Gilesii); otherwise similar to //. Gilesii. Dimensions 

 17 X 12 -5 mm.

Two specimens, both ^, are before me, sent by Mr. 0. French^ 

 F.L.S. A close ally of H. Gilesii mihi, it differs most in its 

 shorter, wider form, greater convexity, much more abrupt apical 

 declivity of discal parts, its wider and more horizontal elytral 

 margins, more nitid surface, finer and more irregular elytral 

 sculpture, besides the other differences noted above. Type in

 minent, eyes approximate, antennae much shorter than prothorax, 

 third joint shorter than fourth and fifth combined, apical five 

 joints considerably wider than preceding, seventh and eighth 

 larger than ninth and tenth respectively, these two short and
