and Asiatic Species of Hapalochrus. 259 



anterior tarsal joints 1 and 2 slightly thickened, 2 projecting 

 over 3; intermediate tibiae (PI. VIII. fig. 21) very strongly 

 incrassate, subtriangular, excavate in their apical third 

 within, and furnished with a rather long, retractile, sub- 

 truncate appendage at about one-fourth from the apex (the 

 tibise thus appearing deeply cleft at the tip when the appen- 

 dage is drawn out of the cavity), the outer apical angle 

 toothed beneath, the lower surface of the tibia bifoveate. 



? . Antennas feebly serrate, joints 5-9 narrow, about as 

 long as broad, almost equal in width ; legs black. 

 Length 3|-3f, breadth 1|-1± mm. (tf ? .)

Described from a series of 22 specimens belonging to the 

 Congo Museum, including eight males ; some females from 

 Manyema in the same Museum, named H. appendicifer by 

 Pic, may belong here. Compared with the last-named insect, 

 the^ of the present speciesmay berecognized by the obliquely 

 dilated, transverse outer joints of the antennae, the less 

 dilated anterior tibiae, the shorter retractile appendage to 

 the middle tibiae, the much finer puncturing of the elytra, 

 and the less robust build. The ? is very like the same sex 

 of the insect here determined as H. azureus, Er. The allied 

 //. duvivierij Pic (? = azureus, Er.), type $ } is said to have 

 subfiliform antennae and coarsely punctured elytra.

<$ . Anterior trochanters with a sharp tooth ; anterior 

 femora obsoletely subangulate at the middle beneath j 

 anterior tibiae moderately widened, sinuate within, obliquely 

 compressed and excavate towards the apex; anterior tarsal 

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

 intermediate femora and tibias usually obscure testaceous, 

 the latter (PI. VIII. fig. 23) very stout, subtriangular, 

 excavate at the apex beneath, and with a short broad lobe 

 below the inner apical angle.
