aciculate, and bearing a horn on the very edge of the clypeus, this 

 horn is long or very long, vertical, flat in front and triangular behind, 

 but even in the great development it does not reach quite as high as 

 the highest point of the vertical walls edging the deep, broad 

 excavation on the prothorax, this excavation reaches from near the 

 anterior margin to close to the base, and is edged laterally by a high 

 wall, which, in the anterior part, is produced into a triangular eleva- 

 tion, and the whole surface of the sides is covered with round 

 punctures neither deep nor closely set, the excavation itself is 

 impunctate ; prothorax ogival, punctulate ; elytra convex, distinctly 

 striate only along the suture, but with a faint second stria visible 

 in the posterior part only, the whole surface is covered with shallow 

 more or less rugose and often confluent punctures giving to the elytra 

 a sub-coriaceous appearance. In the small development the thoracic 

 excavation is deep, but the anterior part of the walls is not produced 

 into a triangular elevation, it is, however, aculeate but remains in a 

 line with the rest of the wall. 



Female : Clypeal part of the head deeply punctate, posterior part 

 smooth ; prothorax simple, punctulate laterally, but smooth in the 

 median part ; scutellum slightly carinate longitudinally ; elytra less 

 coriaceous and with the punctures more distinctly seriate in the 

 dorsal part, the first and second striae are distinct from the base 

 to the posterior rounded part ; metasternum v/ith an impressed 

 longitudinal line as in the male. 



This species is very closely allied to 0. meleagris from Senegal, 

 which, however, is piceous black ; the valves of the penis are dif- 

 ferently shaped, and are longer, less arcuate externally and the 

 apical forcipate part is more oblique. 



Length 9-10|- mm. ; width 5-7 mm. 



Hah. Southern Rhodesia (Buluwayo, Limpopo River). 



I have seen a species from the Galla country which resembles this 

 species so closely as to be almost indistinguishable from it ; the 

 colour, however, is patchy black and the valves of the penis are 

 deeply emarginate outwardly and the forcipate part is not angular 

 and is slightly rounded and attenuate towards the tip. For this, 

 species, I propose the name of 0. emeritus. 



Orphnus eufulus, Bohem., 



Insect. Caffrar., ii., p. 368. 



Male : Brick-red, shining ; head truncate in front and trans- 

 versely quadrate, the truncate apical part is sub-tuberculate laterally 

 and sub-carinate, the cephalic horn, which is vertical, long, and not.
