" Eelated to the preceding species {i.e., P. sugillatiis) are two 

 others, also from Inhambane, one of which is represented by a single 

 example, the other by a few, which are all females. Differential 

 characters could only be taken from the undoubtedly more developed 

 males, and without these it would be useless to give a detailed 

 description. The first species, which might be called 0. mactoAus for 

 the present, is in shape, punctures, and markings exactly as the female 

 of 0. sugillatus, except that it is once as large again, the clypeus is 

 less deeply emarginate and the ridge of the vertex not curved but 

 straight, equally high throughout, and sharply truncate at the sides 

 in front of^the eyes. 



The second species, of which there are three examples, named 

 0. sujfusus for the present, agrees with the first in colour and size, 

 and also in other respects, but the clypeus is, however, emarginate 

 after the manner of 0. sugillatus ; the ridge of the vertex has 

 more the shape of a blunt tubercle, and the elytra are dark blood red 

 almost throughout, and not only at the apex and at the shoulders." 



It is probable that these two species are either females or small 

 developed males of 0. sugillatus.

Onthophagus (Cacconemus) castaneus, Klug, 

 Monatsb. Berl. Acad., 1855, p. 653; Peters' Eeis., 1862, p. 238, 



pi. xiv., fig. 6. 



" Fuscous brown, shining, sides of elytra broadly chestnut red. 



Length 2 J lin. 



One example from Sena ; characterised by a somewhat elongate 

 shape, a peculiar colouration and a smooth, not punctate surface, in 

 which character this species agrees with the following one (0. 

 seminulum) . Head dark brown, almost black, the clypeus with 

 small, scattered granules, apex somewhat upturned, emarginate in 

 the middle, between the eyes is a curved, raised line, and on the 

 vertex a complete transverse ridge, and the space between the two 

 is deepened. The prothorax is convex, smooth and shining, dark in 

 the middle, lighter brown on the sides ; the elytra also are smooth 

 with very fine longitudinal lines, they are light chestnut brown with 

 a common dark brown median patch ; the under side is smooth, dark 

 brown ; only the sides of the sternum and apices of the femora are 

 chestnut brown." 



This species is a Cacconemus according to Jekel.
