equally broad but darker marginal band as far as about the median 

 part, whence it is continued as a narrow line as far as the suture, 

 the apical patch is very broad and greenish black ; in one $ example 

 there is a dark discoidal band uniting the humeral and supra-apical 

 patches, but narrower than the posterior ; tarsi and legs piceous. 



Male : Head punctulate ; clypeus impunctate, outer angles pro- 

 duced each in a moderately long, almost vertical horn, and the 

 centre of the anterior part into a curved horn, bifid at the top, but 

 the bifid process is not divaricating much ; the length of that 

 horn varies from 2 to 7 mm. in the large development, and the 

 shape is very much like that of E. smithi, but the curve of the 

 central clypeal horn is stronger ; prothorax and elytra finely acicu- 

 late punctulate except for a series of punctures along the suture and 

 the outer margin ; pygidium concolorous, finely aciculate ; under 

 side very weakly punctulate on the pectus, each puncture briefly 

 setigerous ; sternal process grooved from the base to the meso- 

 sternal suture, and impunctate ; legs as in E. smithi, but with a 

 plain, although small, tooth on the upper edge of the hind tibial. 



Female: Shape like the female of E. smithi; the head is not so 

 deeply punctate, and the punctures on the sides of the prothorax 

 are small, and not rugose, those on the elytra are similarly fine and 

 not set more closely ; the under side is more deeply punctate than 

 in the male. 



Length 28-38^- mm. ; width 15-19* mm. 



Hah. Natal (Tugela River, Karkloof). 



There seems to be no doubt that E. chloc, Raff., is identical with 

 E. trimeni, and Raffray himself told me so when he was shown an 

 example captured by A. F. Millar in Natal. The rarity of this 

 insect in South Africa is probably due to it being a straggler from 

 the north. Raffray captured his examples in the Bogos province 

 of Abyssinia.

 Mentum ampliated and rounded laterally, ligular part narrower 

 than the mentum, parallel, very deeply triangularly notched, palps 

 cavity very long and broad ; both the lobes of maxilla? mucronate 

 but not hamate in either sex ; antennal club of $ a little shorter 

 than the whole pedicel ; in the $ the clypeus is broadly triangularly 

 dilated from the base to the apex where the outer angles are pro- 

 duced into a long, somewhat reflexed mucronate point, and the 

 central part into an erect horn moderately dilated at apex, the
