644 MR. G. C. CHAMPION ON COLEOPTERA [NoV. 18, 



to the apex, the punctures fine on the disc but becoming much 

 coarser towards the sides anteriorly, the interstices sparsely and very 

 minutely punctured and transversely wrinkled, almost flat towards 

 the suture, convex at the sides, the epipleurae transversely wrinkled ; 

 beneath dark violaceous, shining, the propleiu-se coarsely and sparsely, 

 the sides of the metasternum more finely punctured, the ventral 

 segments finely and rather thickly punctured and aciculate ; pro- 

 sternum broadly, longitudinally depressed between the anterior 

 coxae, the apex broadly produced but very Uttle raised ; legs rather 

 short, dark violaceous, thickly and rather coarsely punctured. 



Length 16|, breadth 5g millim. 



One example, probably a female. In the very broadly widened 

 outer antennal joints (joints 7-10 being about twice as broad as 

 long), the prosternum broad and depressed between the anterior 

 coxae, the comparatively short legs, &c., this insect agrees very much 

 better with Xanthotliopeia than with Strongylium ; and as it does 

 not differ in any important particular from the former I refer it to 

 that genus. Three species only of XantJioOiopeia have been de- 

 scribed, all differing considerably from the present one. Maklin has 

 taken the colour of the palpi as one of the generic characters of 

 Xantliotliopeia ; but the colour of these organs cannot possibly be 

 regarded as of generic importance, though they are conspicuously 

 flavo-testaceous in his typical species, X. rufipennis.

Aspidosternum physopterum, Harold, Mittheil. Miinch. ent. Ver. 

 iv. p. 164. 



One example apparently referable to this species, of which von 

 Harold has only published a brief and very incomplete diagnosis. 

 It has the elytra gradually widened from the base to very far beyond 

 the middle, strongly convex behind, and distinctly costate ; the 

 upper surface greenish-aeneous and shining ; the thorax strongly 

 transverse, rounded at the sides, and sparsely punctured. Several 

 specimens of the same species, from the Cameroons, are contained 

 in Mr. F. Bates's collection ; in one or two of these the elytral 

 costae are almost or quite obsolete, thus agreeing better with von 

 Harold's diagnosis. 



Praogena, Cast. 

 Praogena procera. 



Fraogena procera, Harold, Mittheil. Miinch. ent. Ver. ii. p. 107- 

 Col. Hefte, xvi. p. 131, t. 1. fig. 8. 



A single mutilated example, 25 millim. in length, agrees well 

 with von Harold's diagnosis of P. procera, " Aurato-viridis, niti- 

 dissima, corpore subtus rufo-piceo, pedibus rufo-testaceis, femorum 

 apice, tibiis ultra medium tarsisque nigris," and also with his figure. 

 This is one of the finest known species of the genus.
