Described from a series of upwards of 100 examples, the 

 sexes in about equal numbers, belouging to the Congo 

 Museum. Tiie form with dark intermediate tibiae in (^ is 

 represented by more than 50 specimens from Amadi, and 

 the one with these tibiae red in ^ by at least a dozen from 

 Congo da Lemba. A female of it in the same Museum has 

 been named hy Pic H. testaceicornis, this insect being sepa- 

 rable from the same sex of H. azureiis as here understood by 

 the stouter antennae, and the finer and denser puncturing of 

 the elytra, and from that of H. testaceicoryiis by the shining, 

 hss rugose head. The more strongly appendiculate inter- 

 mediate tibiae of the ^ distinguishes H. inchoatus from 

 H. da/ioneyanus, these two forms having the antennal joints 

 undilated as in J ? of H. testaceicornis and H.fusicornis. 



26. Hapalochrus fusicornis , sp. n. 



(^ . Moderately elongate, rather convex, shining, clothed 

 with semi-erect, whitish puhescence ; bluish-green or green, 

 the basal half of the antennae (a dark streak on joint 1 

 excepted), tlie anterior femora at the tip, the intermediate 

 femora at the base in front, and the anterior tibiae entirely, 

 testaceous. Head short, nearly as wide as the prothorax, 

 closely, finely punctulate ; antennae s-tout, moderately long, 

 tapering from joint 3, the latter much thickened and longer 

 than 2. Prothorax transverse, convex, obliquely narrowed 

 })osteriorly, smooth on the disc, finely punctate at the sides. 

 Elytra oblong, at the base about as broad as the prothorax, 

 a little widened posteriorly, densely, rugulosely punctate. 

 Anterior trochanters unarmed; anterior femora with a small 

 tooth at the base; anterior tibise moderately Avidened, simply 

 sinuate and compressed ; anterior tarsal joints 1 and 2 

 rather long, somewhat thickened, 2 extending over 3 ; inter- 

 mediate tibiffi stout, simply sinuate on their inner and outer 

 aspects, appearing subangulate when viewed from the side. 

 ? . Antennie more slender, feebly serrate, joint 3 not
