a?id Asiatic Species 0/ Hapalochrus. 309 



51. Hapalochrus irregularis, sp. n. 



cJ . Moderately elongate, rather narrow, very shining, 

 sparsely pubescent, and also somewhat thickly set (the legs 

 included) with long, dark, suberect, bristly hairs ; cyaneous 

 or bluish-green, the elytra sometimes brassy, the legs, 

 antennae, and palpi black or metallic, the abdomen in part 

 testaceous. Head and prothorax sparsely punctulate, the 

 latter transverse and smooth on the disc ; antennae serrate, 

 rather stout, long, about reaching the middle of the elytra. 

 Elytra widened posteriorly, sharply margined, depressed on 

 the disc anteriorly, bluntly rounded at the tip ; rather 

 sparsely, irregularly, moderately coarsely punctate, the 

 interspaces uneven, here and there transversely or obliquely 

 plicate. Anterior tibiae with a broad rounded lobe at the 

 middle, and excavate and compressed beyond this ; anterior 

 tarsal joints 1 and 2 thickened, 2 projecting over 3; inter- 

 mediate tibiae moderately incrassate, sinuate, subangulate 

 externally, and deeply excavate at the middle and apex 

 beneath, without lobes at the tip. 



Length 4-4|, breadth lf-2 nun. 



Hab. W. Central Africa, Congo da Lemba (R. Mai/nt : 

 i., ii., iv. 1913), Leopoldville {Dr. A. Dubois : v.-vi. 191.1). 



Described from twelve males belonging to the Congo 

 Museum, all but one from Congo da Lemba. Near the 

 Rhodesian H. furcatus, the antennae much longer, the 

 intermediate tibiae stouter (formed much as in H, angulatus), 

 the median lobe of the anterior pair larger. The elytra 

 have an immature appearauce as in H. mollis (No. 53), the 

 puncturing being much coarser than in that species. The 

 ? is apparently unrepresented in the abundant Congo 

 material before me. 



52. Hapalochrus amadiensis, sp. n. 



S . Elongate, narrow, very shining, sparsely pubescent 

 and also somewhat thickly set with long, semi-erect, blackish, 

 bristly hairs ; cyaneous, the basal joint of the antennae 

 beneath and the ventral sutures testaceous, the rest of the 

 antennae, the palpi, and legs black or metallic. Head and 

 prothorax very sparsely punctulate, the latter smooth on the 

 disc and nearly as long as broad : antennae moderately long, 

 rather stout, subserratc. Elytra long, widened posteriorly, 

 sharply margined, rounded at the tip, depressed on the 

 disc anteriorly ; coarsely, closely punctate, the interspaces 

 here and there transversely or obliquely plicate. Anterior
