Gen. TINIOCELLUS, n. gen. 



Buccal organs of Drejxtnocerus, which it resembles somewhat in 

 general appearance, being very plane on the upper side ; the legs are 

 also similarly shaped ; the spurs of the intermediate and posterior 

 tibiae are very long ; the lateral fovea on the prothorax is also wanting 

 or extremely rudimentary, and there is a visible scutellum.

 Oniticellus humilis, Gerst. Decken's Eeis. Gliederth., p. 138. 



Opaque, slightly aenescent, testaceous brown variegated with 

 lighter brown patches or ill-defined bands ; head covered w^ith 

 moderately long flavescent hairs ; clypeus deeply emarginate in 

 the centre in the male, and with the angles of the emargination 

 projecting and slightly recurved, or very slightly emarginate in the 

 female the raised suture of the gense is not visible, they do not 

 project beyond the line of the clypeus, and there is no trace of trans- 

 verse ridge, or of any impression ; prothorax plane, a little attenuate 

 laterally from the middle to the posterior part and covered with 

 closely set scabrous granules bearing each a decumbent sub-fiavescent 

 hair, and there is a longitudinal impressed line running from about 

 the median part to the base ; scutellum somew^hat elongate and 

 sharp ; elytra as broad as the base of the prothorax, and very slightly 

 longer, attenuate from the humeral part towards the apex, geminato- 

 striate, with the intervals plane and having each two row^s of deep 

 punctures bearing a sub-decumbent hair, eighth interval sharply 

 carinate above the outer margin, along the suture, which is raised, 

 there is on each side a row of erect, rigid whitish bristles which also 

 fringe the apical margin, and in some examples these bristles are 

 noticeable on the intervals ; lateral part of abdominal segments 

 projecting much beyond the wing covers ; mesosternum normal, 

 metasternum somewhat declivous at tip, slightly convex, covered 

 with closely set elongate punctures ; mesosternum invisible ; 

 pygidium sulcate longitudinally in the middle. Length 6^-7 mm. ; 

 width 4 mm. 



Hah. Southern Ehodesia (Salisbury, Victoria Falls), Transvaal 

 (? Boksburg). 



This species was originally described from Abyssinia. I have seen 

 examples from the Galla country which are slightly lighter in colour 

 than the South African ones.
