Grauglbauer (t. c. p. 826) puts B. inflatipes, Eeitt., as a variety of 

 davicornis, Panz. ; but lie discloses no better reason for this than the 

 fact that both were once taken in company. 



B. GLABRATus, Rye. 



I am not in a position to add anything to the published accounts

4 (7). Last joint of palpi with a rounded pi-ominence on the inner side. 



5 (6). Last joint of palpi suh-triano-iilar, not longer than wide, with a large 



rounded prominence at the middle of the inner side... 



hurrellii, Denny, J . 



6 (5). Last joint of palpi oblong-ovate, twice as long as wide, with a rounded 



prominence at the apical third of the inner side... 



distinchis, Chaud., S • 



7 (4). Last joint of palpi without any rounded prominence.

10 (13). Occiput coarsely punctured. Antennae with joints 3 and 4 similar. 



11 (12). Length 1.4-1.5 mm. Antennae with joints 3-8 moniliform .. .
