intermediate row of five gradually larger tubercles towards the 

 declivity, inner row of two large tubercles continuous with three 

 small ones on the declivity, itself forming with its fellow a shallow 

 groove, the interstices finely punctured ; beneath and legs roughly 

 squamose, setigerous ; tarsi stout. 



This species may be placed after B. Hopei, but it is 

 much smaller, with narrower rostrum, the inner row of 

 tubercles confined to the edge of the declivity, &c. 



Bijrsops alveola. 

 B. subovata, squamositate grisea dense tecta ; rostro antice bi- 

 sulcato ; prothorace in medio carinis angustis altis duabus munito ; 

 elytris breviter ovatis, tuberculis majusculis triseriatim dispositis.

Hab. Cape. 



Subovate, densely covered with a greyish squamosity; super- 

 ciliary ridges semicircular ; rostrum longer than the head, with 

 three stout ridges forming two deep grooves between them, the 

 outer ridge joined to the superciliary ridge ; prothorax sub- 

 cylindrical, four-ridged, the two middle ridges linear and raised, 

 forming a narrow groove between them, the lateral ridges inter- 

 rupted, the interspaces more or less excavated ; elytra shortly 

 ovate, each with three rows of tubercles, the outer row of six large 

 oval ones, the intermediate row of four, two only before the 

 declivity, the inner of four, all the tubercles more or less contiguous 

 at the base, and coarsely pitted between the rows, at the base near 

 the suture an oval patch of brown closely-set hairs ; legs dotted 

 with slender black setae ; tarsi rather long. 



The sculpture of the rostrum and prothorax and the 

 larger tubercles on the elytra at once distinguishes this 

 species. It may be placed after B. lutosa. 



Byrsops intermedia. 



B. ovata, squamositate saturate grisea sat tenuiter tecta ; rostro 

 longiore, pauci-foveato ; prothorace subcylindrico, in medio leviter 

 sulcato, antice utrinque late excavato ; elytris ovatis, triseriatim 

 tuberculatis, tuberculis majusculis, approximatis vel subapproxi- 

 matis, basi singulorum macula silacea notatis. Long. 4 liu.
