1. Edge of declivity* rounded. 



Byrsops socia. 



B. subovata, squamositate subsilacea nitida tecta ; rostro sat 

 elongato, basi angustiore, leviter reticulatim foveato ; prothorace 

 angustato, ante medium incurvato, antice late sulcato ; elytris 

 oblongo-quadratis, triseriatim tuberculatis, dorso fere in medio et 

 juxta basin macula communi umbrina notatis. Long. 4 lin. 



Hab. S. Africa. 



Subovate, covered with a somewhat glossy greyish yellow squa- 

 mosity ;f head rather narrow, superciliary ridges strongly raised; 

 rostrum rather long, narrowed at the base, slightly reticulately 

 pitted in front ; prothorax rather longer than broad, incurved at 

 the sides to the middle and thence rounded to the base, coarsely 

 pitted, the apex with a larger pit or groove ; elytra oblong-quad- 

 rate, much broader than the prothorax at the base, each with three 

 rows of mammilliform tubercles, the inner one commencing behind 



* In the Byrsopince the elytra are generally suddenly bent down 

 or truncate behind, the vertical portion constituting the " de- 

 clivity." Our genus Gronops is an exception. 



f What is by some entomologists called a " squamosity " is 

 intended to represent the modern Latin " indumentum," for which 

 our language has no equivalent. In reality squamosity is nothing 

 more than very minute scales, never overlapping, and not always 

 contiguous.
