There appeal's to be a very remarkable similarity between the 

 specimens of this group of Stephanida3 from Johann Albrechtshohe, 

 North Oameroons, and, since several are described from single 

 specimens only, and none from any sufficient number, there may 

 be doubts as to the distinctness of the species. The difficulty of 

 deciding this matter is greatly increased by the fact that the 

 descriptions vary in the amount of the details; the relative length 

 of the basal antenna! joints, and especially details as to the hind 

 legs and femoral teeth, are often wanting. In addition to this, 

 Dr. Enderlein (1) gives a table of the African species of 

 Stejihanus — as then known to him — in which he gives characters 

 differing from those in the detailed descriptions. Thus : tei'e~ 

 bellus — median segment (a) not separated from metapleurse, (6) 

 separated by a raised carina ; togoensis — scarcely or not at all 

 separated ; flavomaadatus — neck («) obliquely striate throughout, 

 (5) finely rugose ; hrevijMtiolatus — face (a) irreguLarly reticulate, 

 (h) finel)^ arcuate rugose. While provisionally retaining these 

 species, further information is required to settle their claims.

$ . Frons irregularly and partly arcuately rugose ; vertex 

 with four transcarinse ; occiput' strongly transrugose, without 

 longitudinal impression. Posterior margin of hea,d sharply 

 bordered. Scape as long as first and second flagellar joints 

 together; second longer than first ; third shorter tha.n first and 

 second together. Pronotum finely transrugose ; semia.nnular 

 centi-ally finely transrugose, laterally coarsely and irregularly 

 punctate. Mesonotum coarsely rugoso-punctate ; scutellum 

 centrally smooth, with a few marginal punctures, lateral rows of 

 punctures distinct, lateral lobes finely ti-ansrugose. Mesopleurte 

 finely rugose and diffusely punctate ; metapleura? confluent with 

 median segment, and, like it, irregularly and coarsely rugoso- 

 punctate, interstices and bottom of punctures very finely trans- 

 rugose. (A few lines before this, the author states " median seg- 

 ment longer than mesonotum and scutellum, finely facetted, 

 between the facets very finely transrugose.") Petiole finely trans- 

 striate, longer than rest of abdomen ; second segment basally 

 coarsely rugoso-punctate, remainder of abdomen smooth . Terebra 

 as long as body, spicula red-brown, shen.ths brown, paler before 

 the black apex. Hind legs with coxpe and femora finely trans- 

 rugose, latter tridentate; teeth in three groups, the central of one 

 tooth only, largest of all ; the basal and apical groups of two 

 each, of which the inner is smallest ; apex of tibise and inside of 

 tarsi clothed with dense red-grey pubescence.
