Scarabaiidae in the British Museum. 519 



Hah, Madagascar, Nossi-Bee. 



This species has very much the appearance of C. minutus, 

 Drurj, but the head has a verj broad but not deep emar- 

 gination. 



The male lias the head shining, almost imperceptibly 

 punctured, the posterior margin and the side-pieces (behind 

 the oblique line) strongly punctured. The horn is thick at 

 its base, moderately acuminate, gently curved. The thorax 

 is almost imperceptibly punctured, and appears smooth, 

 except a space on each side of the fore part of the disk and 

 the anterior angles, the punctures in these places being 

 rather strong, those on the disk not very close together ; there 

 is a strongly impressed punctured median line, extending to 

 the middle of the disk ; the anterior declivity is very slight 

 and has a few small punctures on its anterior surface. The 

 elytra have the stri^ deeply impressed and strongly and 

 moderately closely punctured, but not nearly so much as in 

 C. minutus- the interstices are modei'ately convex. 



The female has the surface of the head a little less shining. 

 The horn has the form of a subquadrate lamina, a little 

 longer than broad, slightly curved, the lower part swollen in 

 front. The thorax has the punctured spaces a little larger 

 and more extended, meeting across the front part of the disk 

 and coming nearer to the base.

This species is closely allied to 0. Jidius, but is shining 



and rather less convex. I have described the large male 



from Mr, B. Ncvinson's collection. Some examples have the
