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

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

 labrum (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 catalogue name which appears in the 

 Munich Catalogue under Hister bengalensis, Wiedem. My 

 specimen probably belouged to Sturm, aud if so, the locality 

 given by him is almost certainly an error. 



Hab. Senegal. Four examples.

I liave one example of this species from Johannesburg 

 which measures 12 mra., but most of ray 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 tlie 

 inner subhumeral 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 Exorhabdus 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 striie ; it is not wholly 

 obliterated. Schmidt made a similar statement regarding 

 Hister aschanti, the subhumeral just passes beyond the 

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

 extremely line, and although it joins the subhumeral it is 

 very distmct.

Brcviter ovatus, parum convexus, niger, nitidus ; fronte stria 

 antice recta ; pronoto stria interna Integra, externa ultra medium 

 abbreviata ; elytris striis subhumerali interna ante medmm 

 abbreviata, dorsalibus profundis, crenulatis, 1-4- integris, 5 apicali, 

 fcuturali basi abbreviata ; propygidio pygidioque vix douse 

 punctatis ; mesosterno fero recto, margiuato ; pedibua piceis ; 

 tibiia anticia 3-deiitatis. 



This species belongs to the series of African species which 

 have a short outer thoracic stria aud a bowed sutural stria
