 Hah. Central or East Somaliland (1897). One example. Type 

 iii British Museum. 



Head, prothorax, legs, aud underside of a purplish-violet colour ; 

 tarsi metallic green above. Elytra black, each with about twenty 

 shallow cupreous pits, which are densely punctured and more 

 or less completely covered with greyish-white pubescence : six or 

 seven of the smallest of these pits are placed at irregular intervals 

 along the third elytral interstice, three of the larger pits on the 

 fifth, three on the seventh, and about seven, diminishing in size 

 from before backwards, along the ninth interstice ; one of the larger 

 pits on the fifth interstice, a little in front of the middle, and one at a 

 short distance behind the middle, encroach upon the sixth interstice 

 and nearly join two correspondingly large pits upon the seventh 

 interstice. 



This species differs from all other African species of the genus 

 known to me in the disposition of the pubescent pits on the elytra, 

 and is further distinguished by having each of the elytra narrowed 

 to a single point, and not truncate at the apex. 



ElATERID-E. 



Ageypnus longicoents Gahan, sp. n. (Plate I. fig. 11.) 



Rufo-brunneus, luteo-pilosulas ; antennis nigris, basin elytrorum 

 paidlo superantibus, articulo 3° quam 2° hand longiore, articulis 

 4" ad 10" m angidatim sat valde productis ; prothorace quam 

 latiori vice longiori, supra sat valde convevo, lateribus medio 

 paxdlo rotundatis, angulis posticis tenuibus, acutis, divaricatis ; 

 elytris tenuiter punctato-striatis. Long. 17, lat. 5 mm. 

 Hab. Central or East Somaliland (1897). One example. 

 Type in British Museum. 



In general appearance this species resembles A. bocandei Cand., 

 but is easily to be distinguished by the black colour and greater 

 length of its antennae. The third joint of the antennas is a little 

 broader, but not longer, than the second, and the joints from the 

 fourth to the tenth are each produced antero-distally into a strong 

 angulate process ; the disc of the prothorax is more convex and 

 somewhat less densely punctured, and the sides are more rounded 

 in the middle than is the case with A. bocandei. 



DASOILLIDiE. 



Geneceeus nebulosus Gahan, sp. n. (Plate I. fig. 9.) 



Piceo-brunneus, cinereo- sat dense pubescens ; elytris brunneo- 

 nebulosis, longitudinaliter subcostatis ; antennis ( 3 ) Jlabellatis 

 vel ( $ ) serratis. Long. 14—16, lat. 4-4| mm.
