1883.] BEETLES OF THE FAMILY EROTYLID^. 87 



on its disk ; elytra rather deejily striated at their bases, but the 

 strias not continued to the middle. The black patch on the elytra 

 leaves only a narrow band at the base, the entire margin as far as the 

 last stria, and about two fifths at the apex, red. 



The thorax has a distinct fovea on each side of the base, in which 

 are a few larger punctures. The elytra are gibbous, depressed at 

 the base, and with a deeply impressed marginal Hue. 



1 have seen one specimen in the collection of the late Mr. Crotch 

 at Cambridge ; and there is one in my own, given me bv Mr. 

 Bartlett.

Ovatvs, minus convexus, rufus ; capita prothoraceque minute sed

Long. 8 niiUim. 



Hab. Africa occid., Camaioon Mountains. 



Broadly ovate ; elytra without striae, punctuation scarcely visible 

 under a strong lens ; tibiae very broadly dilated ; club of tlie uutennse 

 dark. Tiiis is an insect aUied to P. httmeralis. Crotch ; and I 

 should hardly have ventured to assert its distinctness, the descrip- 

 tion of that species being so brief, but that fortunately the unique 

 type from Murray's collection is now in my own. 



It differs from P.humeralis in being less convex, in wanting any trace 

 of striae, and in the black margin which surrounds the elytra except 

 at their bases, and which is very distinct. The rest of the insect, 

 with the exception of the club of the antennae and the epistoma in 

 front, is deep brick-red, A single example.
