POLYAULACUS BRUNNEUS, Chaud., 



Log. cit., p. 157. 



Pale testaceous red, with the head darker ; head depressed 

 anteriorly, with closely set plicce running longitudinally from the 

 epistome to the neck ; prothorax hardly broader than the head, 

 nearly parallel laterally, but with the outer posterior angle recurved, 

 the base truncate without any sinuation, plane and closely set with 

 deep punctures ; elytra parallel, depressed, nearly twice as broad as 

 the prothorax and four times as long, punctato-striate, with the inter- 

 vals slightly convex and very slightly shagreened, third interval with 

 two evanescent punctures; under side, antennae, and legs flavescent. 

 Length 4|- mm. ; width 1|- mm. 



Hab. Zambezia (Salisbury). 



My example from Salisbury is not so dark as the type of De 

 Chaudoir, and the suture as well as the posterior margin are slightly 

 iafuscate. I have no doubt, however, that the two are identical. 

 The original species came from Zanzibar.
