488 Mr. F. P. Pascoe on some new or little-knoiun 



Sessinia [(Edemeridse]. 

 This genus, founded on those species of Nacerdes with two spines 

 to their anterior tibiae, was proposed bj me in this Journal in January 

 1863. M. Leon Fairmaire, in the French ' Annales ' for August in 

 the same year, named the group Ananca, apparently not aware that 

 it had been previously disposed of.

There are several points of structure common to this and Seller's 

 genus Cylindrothorus. The pronotum, however, is quite distinct 

 from the flanks of the prothorax, although its separation is only 

 marked by a very delicate line, which is continuous with the ordi- 

 nary border-line and dips down at the sides, so that the flanks rise 

 into a gradually narrowing point at each extremity. The penulti- 

 mate joint of the tarsi is prolonged underneath the claw-joint, but 

 can scarcely be called lamellate. The labium is almost membranous, 

 and is attached to the mentum by a broad peduncle. This genus 

 appears to form the type of a distinct subfamily. 



Othelecta torrida. (Pi. XTX. fig. 5.) 



O. nigra, nitida ; elytris castaneis, longe et disperse pilosis. 



Hab. 'NGami. 



Black, shining ; head and prothorax closely punctured, the punctures 

 small, but deep and distinct, having at the bottom of each a whitish 

 secretion ; elytra brownish chestnut, oblong-oval, rather pointed behind 

 and much broader in the female, finely but irregidarly and rather re- 

 motely punctured, and having long, dispersed black erect hairs ; body 

 beneath and legs reddish chestnut, closely punctured, especially on the 

 femora ; tarsi clothed with close-set black stiiRsh hairs. Length 7-8 

 lines.
