338 Mr. F. P. Pascoe on Byrsops, 



This germs is at once differentiated from Synthocus by 

 its intermediate coxre separated by a broad and truncate 

 mesosternum, and tibiae sharply spurred at the apex. 

 The genus represented by a remarkable form -with very 

 broad elytra, abruptly declivous posteriorly.

 E. latissime ovata, grisescens ; prothorax cum capite squamo- 

 sitate griso-fulva sat dense tectus, Lie tuberculato-marginatus ;

 munito ; corpus infra pedesque squainositate grisea tecti. Long.

Head and prothorax covered with a greyish-fulvous squamosity, 

 but darker and thinner on the elytra ; front of the head flattish, 

 between the eyes two small approximate tubercles ; rostrum 

 longer than the head, transversely gibbous behind the middle ; 

 prothorax short, gradually rounded from the apex to the base, the 

 disc very irregular and tuberculate, tubercles round the margin 

 contiguous, each tipped with a black seta, tubercles in the middle 

 and base fewer ; no scutellum ; elytra broader than long, flat 

 above, each with a raised flexuons line, the suture with a finer 

 raised line not continued to the declivity, the sides and shoulders 

 tuberculate, at the base and away from the suture a mammilliform

 rows of small tubercles ; basal segment of the abdomen as loug as 

 the three next together.
