records from Senegal and East German Africa, as well as from 

 the Cape. Harold says, in order to show the distinction between 

 the two, that the vertex of the head in the female, instead of 

 having a transverse carina with a small horn in the middle, is 

 obsoletely tuberose transversely. 



Oniticellus triangulatus, Har., 

 Coleopt., Heft, xi., 1873, p. 105. 



This species is very closely allied to the preceding one ; it is, 

 however, usually smaller, the punctures on the prothorax are closer 

 and smaller, and are in size not unlike those of 0. flavipes of 

 Southern Europe, but the distinctive character is found in the 

 shape of the clypeal carinse, which is very distinct from that of 

 0. flavipes and 0. 2)allipes. Whereas in the former the clypeal 

 carinas are almost wanting in the male, and in the female there 

 are two distinct ones, an apical following the contour of the 

 clypeal margin, and another curved and sub-median, in 0. triangu- 

 latus there is a nearly median, straight transverse ridge, and in 

 the anterior part a sharply triangular one the apex of which 

 nearly reaches the transverse ridge, the shape of these ridges is 

 the same in both sexes, but in the male there is a frontal impres- 

 sion often a little deeper than in the female ; the prothorax is 

 not variegated with greenish-bronze patches, but there are five 

 distinct ones, one near the apex, two at middle, and two, some- 

 times less distinct than the others, on the median part of the 

 base ; the mesosternum has a broad, smooth, triangular, raised 

 process which dees not, however, project on the mesosternum 

 which is nearly as wide as in 0. j9aZZ7^j>es, but is not tuberculate 

 at apex ; shape and sculpture of elytra, pygidium, and metasternum 

 as in 0. jmllij^es. 



Length 7-10 mm. ; width 4-5 mm.
