This species has little to separate it from Hister major, L., 

 except its size, greater breadth, and less convexity, and tlie 

 labruni (a very important character) is narrower and one- 

 third wider. I have a specimen which is apparently the 

 same species as the above; it is labelled " medius Sturm 

 Ind. or.^' This is a cataloj<ue name which appears in the 

 Munich Catalogue under Hister bengalensis, Wiedem. ^My 

 specimen probably belonged to Sturm, and if so, the locality 

 given by hirn is almost certainly an error. 



Hub. Senegal. Four examples. 



Macrolister rohusticollis, Lew. 



I have one example of this species from Johannesburg 

 ■which measures 12 mm., but most of my specimens approxi- 

 mately measure 9 mm., the size of the type example.

Formerly I considered that Schmidt's description did not 

 apply to my species, because he stated that in paganus the 

 inner subhumcral stria was complete, but the stria terminates 

 in the middle, the oblique basal stria is very distinct but it 

 does not join it. In the species I have assigned to the 

 genus Exorhubdus the inner subhumeral stria is complete 

 and similar to the first dorsal stria, and the oblique stria is 

 faint, but it is traceable in the interstice between the 

 first dorsal and the subhumeral stride ; it is not wiiolly 

 obliterated. Schmidt made a similar statement regarding 

 Hister aschanti, tlie subhumeral just passes beyond the 

 middle only, the stria at the base is the oblique stria and is 

 extremely tine, and although it joins the subhumeral it is 

 very distinct.

This species belongs to the series of African species which 

 have a short outer thoracic stria and a bowed sutural stria
