new Species of ll'\ster'u\ve. 231 



pygidium is evenly, almost denselyj set with larger punctures, 

 and tliere is a granulate surface between the punctures whicli 

 may be seen under the microscope, posteriorly there is a 

 smooth narrow rim ; the prosternum is narrow, anterior lobe 

 jjunctulatc and bordered laterally with two stria3 ; the meso- 

 sternum is almost truncate, with a marginal stria which con- 

 tinues along the sides of the metasternum ; the anterior tibia 

 are 4-dentate. 



Uisfer circulus, Sell., and H. circulari's, Lew., somewhat 

 resemble this species in general facies. The ocular projec- 

 tions resemble those of certain IloloIepU^^ and they are seen 

 but are very minute in H. circularis.

Mr. Guy A. K. Marshall has sent me a series of this 

 species found at Salisbury in Mashonaland among rotten 

 horns and hoofs. Mr. Marshall says : — " I was pleased in 

 being able to ascertain the reason of its presence there ; I find 

 that it lives on the larvae of the large horn-destroying ' micro ' 

 Tinea vestella, L., for on several occasions I captured the 

 beetles in the act of devouring the larva, and they are, as a 

 rule, chiefly found in the larval cases." 



Hister Uohtbi is somewhat like a species of Pac/iycrcBrus 

 in outline, and I give a tigure (fig. 2) to show the striaB of 

 the prostcrnal lobe. In several African species the lobe is 

 similarly bistriate.
