angularly dilated at the middle, and excavate and com- 

 pressed beyond this ; anterior tarsal joints 1 and 2 slightly 

 thickened ; intermediate femora arcuately hollowed before 

 the apex beneath ('appearing angulate at the middle) ; inter- 

 mediate tibiae (PI. VIII. fig. 20) broadly, abruptly incrassate 

 from near the base to the apex, slightly excavate and with a 

 very small compressed lobe near the inner apical angle, the 

 lower surface foveate at about the middle. 



? . Antennae much shorter and not nearly so stout, the 

 joints always considerably longer than broad.

Described from a series of about thirty males and forty 

 females belonging to the Congo Museum. Very like H. den- 

 satus, Bourg. (No. 41), the <$ with much longer and stouter 

 antennae, less dilated anterior tibiae, and broader, less exca- 

 vate intermediate tibiae, the elytra relatively shorter. The 

 antennae are less dilated in the $ , and the elytra more coarsely 

 punctured, than in H. mashunus (No. 39). The females of 

 these insects are scarcely distinguishable one from another. 



32. Hapalockrus patruelis, sp. n. 



$ . Extremely like H. longicornis, cyaneous, the head 

 and prothorax violaceous, the antennal joints 1-5 (the upper 

 surface of 1 excepted) testaceous, the others black, the legs 

 nigro-cyaneous ; antennae much shorter, barely reaching the 

 middle of the elytra, rather stout, somewhat filiform ; head 

 closely punctulate ; prothorax transverse, rugulosely punctate 

 at the sides ; elytra densely, roughly punctate ; anterior 

 trochanters with a long slender tooth ; anterior tibiae dilated 

 at the middle ; intermediate femora deeply, arcuately 

 hollowed before the apex beneath (appearing sharply toothed 

 at the middle) ; intermediate tibiae somewhat broadly 

 dilated from near the base to the apex, slightly excavate and 

 with a very short compressed lobe at the inner apical angle. 



? . Antennae more slender and less elongate, the basal 

 joints darker.
