35. Hap alochrus plat ycerus, sp. n. 



cJ. Elongate, narrow, bluish-green or cyaneons, the 

 antennse black ; clothed with whitish pubescence intermixed 

 with longer, semi-erect, soft hairs. Head nearly as wide as 

 the pi-otliorax, almost unimpressed, densely, rugosely, punc- 

 tate; antennae moderately elongate, stout, joints 5-9 broadly, 

 obliquely dilated, 7-9 twice as broad as long, 10 oblong. 

 Prothorax convex, a little broader than long, rounded at the 

 sides, obliquely narrowed behind, rugosely punctured late- 

 rally, much smoother on the disc. Elytra long, widened 

 posteriorly, rounded at the apex, densely,rugulosely pun(;tate. 

 Anterior femora thickened, bearing a small tuft of stiff hairs 

 at the base ; anterior tibiae stout, sinuous within, obliquely 

 compressed and Avith a narrow diaphanous space on their 

 inner aspect before the tip ; anterior tarsal joints 1 and 2 

 stout, 1 longer than 2, 2 extending over 3 ; intermediate 

 tibiae curved, convex externally, broadly, abruptly widened 

 from near the base, strongly sinuate and excavate within, 

 and with a rather broad, compressed appendage near the 

 inner apical angle and a narrow aj)pendage below the outer 

 angle. 



? . Antennae shorter, joints 5-9 much less dilated, 4-8 

 gradually widened. 



Length 6, breadth 2 mm. {(??.) 



Hub. E. Afhica, Lukanga in N. Rhodesia {H. C. DoUman : 

 24. iv. and 1. v. 1915). 



One pair. In this insect the antennae of the cJ are 

 greatly dilated (joints 6-9 being broadly lamellate) and the 

 head is strongly rugose in both sexes. The (J has the 

 anterior tibiae formed as in H. clavicornis, and the inter- 

 mediate tibiie broadly widened, sinuate and excavate within, 

 and bearing' a rather broad compressed appendage near the 

 inner apical angle. 



36. Hapalochrus rugosus, sp. n. 



(J . Moderately elongate, rather dull, the prothorax 

 shining ; blue or bluish-green, the antenn;e, palpi, and legs 

 black or metallic, the intermediate tibiae of S testaceous at 

 the apex within, the ventral sutures rufcscent ; thickly 

 clothed with shaggy whitish pubescence intermixed witli 

 long, erect, soft liairs. Head short, flattened, densely, 

 rugosely punctate; antennae moderately long, serrate, dilated 

 from the fifth joint onward. Prothorax broader than long, 

 obliquely narrowed behind, rugosely punctured at the sides,
