margined by rounded and not very prominent ridges, a little more 

 than twice as broad as it is long; its upper part somewhat hirsute. 

 Mesopleurae with a very distinct, oblique, polished ridge in front 

 ofthemiddle coxa;; thèse with an oblique, curved, but not very de- 

 finite ridge. First sternite with a médian carina produced in the middle 

 into a very prominent, obtuse, triangular tooth. 



Smicromyrme (T.) kachiobweana var. jankisiaca (Bischoff). 



In this form the clypeus and ail structures we hâve compared in the 

 maie are as in kachiobweana, except that the tubercles of the seventh 

 sternite are ail but obsolète. The hairs of the ocellar région, as noted 

 by Bischoff, are in part black in the type spécimen. In another, some- 

 what larger spécimen which we refer to this form on the strength of 

 its obsolescent processes of the seventh sternite, the ocellar hairs are 

 entirely grey. Bischoff séparâtes his tanganjicx and with it jankisiaca 

 from kachiobweana and mufungwensis on the basis that the latter two 

 possess a densely pubescent dorsal surface of the propodeum,whereas in 

 the former the propodeum is less thickly and more erectly clcthed. 

 The types of ail but tanganjicœ are before us and we find no appréc- 

 iable différence in the vestiture of the propodeum of the three forms; 

 mufungwensis, however, belongs in another species group. In ail 

 respects the structure of jankisiaca is so close to that of kachiobweana, 

 that we can only consider it at most a variety of this species. As to 

 whether such is also true of tanganjicse, not having seen spécimens, we 

 cannot express an opinion. 



Smicromyrme (Trogaspidia) bunkeyana (André). 



We hâve also examined the unique, maie type of this species. The 

 anterior margin of the clypeus has a broadly bevelled emargination, 

 terminating laterally in a blunt peg-like tooth, the top of which is 

 truncate and microscopically punctulate; laterad of the base of thèse 

 teeth the disk of the clypeus is striolate to the condyle of the mandibles; 

 this médian, bevelled edge corresponds to the impressed basin of 

 such species as kachiobweana.
