and Asiatic Species of Hapalochrus. 307 



Anterior tibiae sinuate, compressed before the tip ; anterior 

 tarsal joints 1 and 2 slightly thickened, 2 extending over 3 ; 

 intermediate tibiae moderately thickened, sinuate externally, 

 without lobe at the inner apical angle, excavate at the middle 

 and apex beneath. 



Length 3^, breadth If mm. 



Hab. W. Central Africa, Nyangwe, Belgian Congo 

 (R. Mayne: iii.-iv. 1918). 



One male. This species agrees with H. testaceicornis, 

 dilaticornis, &c, in having a finely rugulose, opaque, blue 

 head ; but it differs from them in the basally unarmed 

 anterior femora, the simply sinuate, feebly incrassate, non- 

 appendiculate intermediate tibiae, and the undilated antennae 

 (which are formed as in the ? of the insects mentioned), 

 of the <J . H. inchoatus, found at the same date at 

 Nyangwe, has a shining, more distinctly punctured head, 

 H. angulatus, from the Aberdare Mts., is perhaps the nearest 

 allied form to H. cyanocephalus, the latter having the elytra 

 less dilated posteriorly and more densely and not so coarsely 

 punctate, and the intermediate tibiae of $ less angulate 

 externally. 



49. Hapalochrus rhodesianus, sp. n. 



$ . Moderately elongate, shining, sparsely clothed with 

 fine pubescence intermixed numerous long, erect, fuscous 

 hairs ; blue or bluish-green, the head and prothorax some- 

 times brassy-cupreous, the antennae, palpi, and legs black or 

 metallic. Head short, slightly depressed in front, sparsely 

 punctate ; antennae rather short, broad, serrate, joints 5-9 

 strongly transverse. Prothorax much broader than long, 

 a little wider than the head, very sparsely punctate, smooth 

 and feebly canaliculate on the middle of the disc. Elytra 

 widened posteriorly, depressed on the disc below the base, 

 coarsely, closely punctate, the puncturing becoming a little 

 sparser anteriorly. Anterior trochanters with a curved, 

 hook-like tooth ; anterior femora with two or three setae at 

 the base ; anterior tibiae sinuate, compressed towards the 

 apex ; anterior tarsal joints 1 and 2 slightly thickened, 

 2 extending over 3 ; intermediate tibiae moderately and 

 abruptly widened from a little below the base to near the 

 tip, excavate at the apex beneath. 



? . Antennas much more slender, feebly serrate. 



Length 3|-5, breadth lf-2 mm. (^ ? .) 



Hab. E. Africa, Mwengwa in N.W. Khodesia (H. C. 

 Dollman : xii. 1913 and i. 1914).
