40 Mr. G. J. Arrow on the 



having upon each elytron five dorsal stria? (that is, striae 

 lying between the suture and the humeral callus) equidistant 

 from each other and without rows of punctures between 

 them. The ventral segments are each divided at the sides 

 into two pseudo-segments by a carina from which spring- 

 hairy fringes, and in most species another row of hairs arises 

 from the anterior margin of each segment. This double 

 fringe is not visible at the extreme outer edge of the abdomen, 

 and is most apparent, when present, in the penultimate 

 segment. 



Most of the species are subject to very great variation in 

 pigmentation, especially upon the elytra.
