200 On African and Asiatic Spates of Hapalochrus. 



strongly transverse, oblique, 3 triangular. Prothorax con- 

 vex, transverse, about as wide as the bead, obliquely narrowed 

 posteriorly, shining, sparsely, very finely punctulate. Elytra 

 long, a little broader than the prothorax, slightly widened 

 posteriorly, sbining, densely, rugulosely punctate, smoother 

 at the base. Anterior trochanters produced into a short 

 point; anterior femora with a small tooth at the base ; anterior 

 tibiae twisted, broadly, obliquely dilated and excavate at the 

 middle ; anterior tarsal joints 1 and 2 thickened, 2 extend- 

 ing over 3 ; intermediate femora broadly excavate at the 

 base beneath ; intermediate tibia? (PL VIII. fig. 18) greatly 

 thickened, widening outwards, deeply, abruptly excavate in 

 their apical third within, and furnished with a long, curved, 

 narrow, compressed appendage near the inner angle and a 

 slightly shorter appendage beneath the outer angle, the apex 

 appearing bilobate when viewed from behind. 

 Length 4£, breadth 2 mm.

 vii. 1910). 



One male. Extremely like H. testaceicornis, Pic (191 4), 

 a <$ of which, from Nyangwe on the Congo, named by the 

 author, has been lent me by M. Schouteden ; but differing 

 from it in the longer and more broadly dilated antennae, the 

 testaceous intermediate femora and tibiae, the tibiae with 

 longer apical appendages and wanting the fovea beneath, the 

 anterior tibiae with a broader ear-shaped lobe at the middle. 

 Less elongate than the Rhodesian H.platycerus, <$ (No. 35 ), 

 the head not so rugose, the antennae shorter and broadly 

 lamellate from the base, the legs and antennae partly testa- 

 ceous. 



24. Hapalochrus testaceicornis. 



? Hapalochrus testaceicornis, Pic, Melanges exot.-enlom. x. p. 15 (J) 

 (Oct. 1914). 



£ . Antennae shorter and less dilated than in H dilali- 

 cornis, joints 6-9 transverse, 1-6 testaceous, 7-10 black ; 

 anterior trochanters produced into an acute tooth ; anterior 

 femora with a small tooth at the base ; anterior tibiae broadly 

 dilated and excavate at the middle ; anterior tarsal joints 

 1 and 2 thickened, 2 extending over 3 ; intermediate femora 

 excavate and testaceous at the base beneath, for the rest 

 black ; intermediate tibiae black, greatly thickened, deeply, 

 abruptly excavate towards the apex within, and with a long, 

 curved, basally-dilated appendage at the inner apical angle 

 and a short tooth below the outer angle, the lower surface 

 deeply foveate beyond the middle.
