By. fasciatus. Forster.—Steph. Catal. 98. No. 1031. 



Short, ovate, black, tomentose : thorax clouded with aureous : elytra with in- 

 terrupted black stripes, and a duplex, arcuated, abbreviated, rufo-ferruginous 

 fascia in the middle, somewhat resembling the figure of a crown.

 duplex abbreviated fascia, composed of confluent whitish dots. 



Var. y. Steph. Catal. I. c. — Head with a fuscous pubescence, with three black 

 streaks ; elytra with four longitudinally interrupted black streaks, a common 

 subannular whitish spot, and some dots of the same. 



Very variable in colour; sometimes nearly black, immaculate. 



Differs from the two preceding in being shorter, but not narrower, with the 

 pubescence more glossy and brilliant, especially towards the sides and apex 

 of the elytra. 



Less common than By. pilula, though far from uncommon 

 throughout the metropolitan district; in Suffolk, Norfolk, Devon- 

 shire, &c. " On the sand-hills (near Swansea), not common." —

Sp. 4. oblongus. Oblongo-ovatus, piceo-ater, thorace immaculato, elytris vittis

 Byr. oblongus. Sturm— Steph. Catal. 98. No. 1032. 



Oblong-ovate, pitchy-black, clothed with a fuscous-brown pubescence; the 

 thorax immaculate : elytra with three interrupted black streaks and several 

 distinct white spots, forming two transverse waved fascise: body beneath and 

 legs black or brownish. 



This differs from By. fasciatus in being more oblong, and in having the thorax 

 immaculate, the elytra less distinctly striped, and having larger and more 

 evident white spots, which are differently disposed, the rows of spots being 

 subparallel with each other, which is not the case in the insect last named. 



Found occasionally within the metropolitan district: on Hamp- 

 stead-heath, Wimbledon-common, &c.
