516 Mr. C. 0. Waterliouse on new 



The male has the horn on the head as in G. lunaris, but 

 is more slender, and the apex itself is not so sharp. The 

 thorax is as in G. lunaris, but the median dorsal line is less 

 marked ; the median lobe is truncate in front, with four 

 nearly equal and equidistant tubercles ; in the fully deve- 

 loped male this lobe is a trifle broader in front than poste- 

 riorly, its anterior vertical surface is densely and coarsely 

 punctured, even slightly rugose ; the deep impressions on 

 each side of the lobe are rather strongly punctured ; the sub- 

 lateral tooth does not turn outwards so much as in G. lunaris, 

 and in the fully developed males its upper edge is bisinuate, 

 so that a second obtuse tooth is formed ; the middle of the 

 disk is almost smooth or with a few very fine punctures, but 

 the sides of the middle lobe are distinctly punctured, and the 

 front margin of the lobe and the base of the thorax (behind 

 the impression) are still more distinctly punctured, the punc- 

 tures being moderately close together ; at the sides of the 

 thorax the punctuation is rather strong and very close. 



The female is like the female of G. lunaris, but the thorax 

 is less convex, the median line is less impressed, and there is 

 less anterior declivity. The horn on the head is similar. The 

 thorax has the sculpture very similar, but not quite so strong, 

 and is distinctly less rugose near the anterior ridge ; there is 

 little or no smooth space at the posterior part of the disk ; 

 the anterior declivity is very closely and rather strongly punc- 

 tured, with a tendency to be rugose. 



Copris orion, Kl., and G. amyntor, Kl. 



There is some uncertainty in the identification of these 

 species. In Erman's ' E-eise,' Atlas, p. 34, C. orion is stated 

 to be the insect known in Ecklon's list as G. caffra and G. 

 Irevicornis ; it is distinguished from G. lunaris by its small 

 size and " ferner ist das Halsschild, welches bei G. lunaris 

 fast glatt zu sein pflegt, hier deutlich und grob punctirt. 

 Die Streifen auf den Deckschilden sind tiefer eingegraben, 

 und die Zwischenraume mehr oder weniger deutlich punctirt." 

 In the Latin diagnosis the expression " interstitiis obsolete 

 punctatis " is used. 



C. orion of Boheman is certainly the insect known to me 

 by that name, having the head almost entirely smooth, with 

 the elytra so smooth that it is only with a strong magnifying- 

 power that the punctures can be seen. 



It is just possible therefore that C. orion, Boliem., from 

 South Africa, may be distinct from C. orion, Klug, from 

 Senegal.
