new Species of Histeridae. 231 



pygidium is evenly, almost densely^ set with larger punctures, 

 and there is a granulate surface between the punctures which 

 may be seen under the microscope, posteriorly there is a 

 smooth narrow rim ; the prosternum is narrow, anterior lobe 

 punctulate and bordered laterally with two strise ; the meso- 

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

 tinues along the sides of the metasternum ; the anterior tibise 

 are 4-dentate. 



Hister circulus, Sch., and H. circularise Lew., somewhat 

 resemble this species in general facies. The ocular projec- 

 tions resemble those of certain Hololeptce^ 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 larv£e of the large horn-destroying ' micro ' 

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

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

 rule, chiefly found in the larval cases." 



Hister Holuhi is somewhat like a species of Fachycrcerus 

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

 the prosternal lobe. In several African species the lobe is 

 similarly bistriate.
