anterior tarsal joints 1 and 2 slightly thickened, 2 projecting 

 over 3j intermediate tibise (Pi. YIII. 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 

 tibiae thus appearing dee|)ly 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.

Descril)cd from a series of 22 specimens belonging to the 

 Congo Museum, including ci^ht males ; some females from 

 Manyema in the same Museum, named H. appendicifer by 

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

 the S of the presentspeciesmay be recognized by the obliquely 

 dilated, transverse outer joints of the antennae, the less 

 dilated anterior tibije, the shorter retractile ajjpendage to 

 the middle tibia?, the much finer puncturing of the elytra, 

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

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

 H. duvivieri. Pic {? = azureus, Er.), type ^ , is said to have 

 subHliform auteunee and coarsely punctured elytra.

 femora obsoletely subangulate at the middle beneath ; 

 anterior tibia3 moderately widened, sinuate within, obliquely 

 com[)ressed and excavate towards the apex; anterior tarsal 

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

 intermediate femora and tibiae usnally obscure tcstaceons, 

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