on its disk ; elytra rather (lee])ly striated at their hases, but the 

 striae 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 line. 



I 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. 



29. PaL;5eolybas cychramoides. 



Ovaius, minus convexus, rufus ; capite prothoraceque minute sed 

 distincte punctntis, illo epistnmafe nigrescente ; elytris minutissime 

 punclatis, fere lavibus, callo humerali margineque (ad apicem 

 latius) nigris. 



Long. 8 millim. 



Hab. Africa occid., Camavoon Mountains. 



Broadly ovate; elytra without striae, punctuation scarcely visible 

 under a strong lens ; tibice very broadly dilated ; club of the antennae 

 dark. This is an insect allied to P. humeralis. Crotch ; and I 

 should hardly have ventured to assert its distinctness, tlie 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 m being less convex, in wanting any trace 

 of striae, and iu the black margin which surrounds the el) tra except 

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

 with the exception of the club of the antenna} .and the epistouia in 

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