A rather small, narrow, somewhat convex, cyaneous or 

 bluish-green form ; the antennae comparatively slender, 

 subfiliform, testaceous in (J , with the apical joints usually, 

 and sometimes the basal ones above, infuscate or black ; the 

 head and prothorax very shining, the eyes rather large ; 

 the elytra closely, coarsely, rugulosely punctate, sometimes 

 with a brassy lustre ; the anterior and intermediate tibioe 

 and the intermediate femora usually obscure testaceous in (^ . 

 This is the only W. African Hapalochrus known to me to 

 which Erichson^s brief description would apply ; liis type, (^ , 

 "wanted the posterior legs. Murray omitted to mention tlie 

 sexual characters of his H. cceruleus, and Thomson is also 

 silent in this respect. The British Museum has a long 

 series of the present species from various localities on the 

 W. coast of Africa, as well as many from Uganda. In the 

 Belgian Congo, H. azureus must be an abundant insect, as 

 there are upwards of 550 examples of it in the Congo 

 Museum, including about 130 males ; but the species is not 

 represented in DoUman's E-hodesian Collection. A very 

 small ^ from Wombali has miich narrower intermediate 

 tibiae, and it may not be conspecitic with others from the 

 same locality. The H. duvivieri, ? , of the Congo Museum 

 collection, named by Pic, has the antennal joints 2 and 3 

 greatly elongated, and it probably belongs to Laius spini- 

 coxis, of the same author; H. sinuatipes, Pic (1911), from 

 E. Africa, seems to be an allied form.

 tlie apex within; anterior tarsal joints 1 and 2 slightly
