was a compound one, having had the head of a quite different 

 species, probably Diceros peteli, attached to it. It is true that the 

 head of this specimen has at some time been detached and re-fixed, 

 but it is not the head of D. peteli, and there is no reason to consider 

 it other than the original one.

Shining black above and below, except for a nearly circular 

 orange patch at the outer margin of each elytron a little before 

 the middle. 



The clypeiis is quadrate, with the front margin nearly straight^ 

 recurved and slightly produced in the middle, the front part 

 excavated and the posterior part rugosely punctured, broadly 

 elevated in the middle and forming in front a broad arcuate 

 projecting crest. The protliorax and scuiellvm are very finely 

 punctured, the former strongly bisinuated and margined at the 

 sides and the marginal lines complete. The eh/tra are very lightly 

 serially punctured and scarcely rugose at the apices. The pyr/idiinn 

 is finely transversely rugulose, the metasternum is coarsely punc- 

 tured at the sides, and the ventral se(jmcats have each a row of fiue 

 punctures at the middle.

Shining black, with the pronotum (except a large more or less 

 cruciform black mark at the centre), the scutellum, femora, parts 

 of the sternum and the terminal part of the abdomen deep blood- 

 red, and a large bright yellow patch about half the length of the 

 elytra placed before the middle of each and reaching the outer, 

 but not tlie inner, margin. 



The chjpeus is quadrate and nearly straight in front, with 

 the margin strongly raised and slightly and broadly produced 

 in the niiddle, the front part excavated and smooth and the 

 posterior ])art punctured and provided with a carina which is 

 bluntly produced in front. The pronotum is very smooth and 

 convex and exceedingly finely punctured, with the sides strongly 

 bisinuated and margined, the marginal stria? being complete. Tiie 

 scuteUinn has only a very few fine punctures, and the elytra are 

 very lightly serially punctured, with the apices slightly rugose. 

 The pyf/idhnn is finely transversely strigose, the metastermim
