lights, a slight mixture of fulvous pubescence ; 5th and Gth segments 

 clothed with appressed silvery-sericeous pubescence ; apical segments 

 black, with an anal tuft of long black hairs ; beneath, the thorax and 

 ventral segments are silvery-sericeous. Length 6^ lines. 



This species is readily distinguished from all others, by the fulvous 

 head, and silvery band of the abdomen above. It was collected and 

 presented to the Society, by Mr. William Saunders, of London, Canada 



West.

 the eyes a large rhomboidal impression, beneath which are two small 

 smooth spots, and a little lower down the face is tinged with green ;

 densely punctured, sides more densely and somewhat rugosely punc- 

 tured, with a deep depression near the lateral margin ; on each side of

 the suture; purple, tinged with coppery towards the apex, densely 

 punctured; on each elytron at base, a circular depression, the outline 

 of which is obsolete behind towards the suture, in the middle of this 

 depression there is a small lunular elevation; a little above the middle

 the lateral margin, a small transverse coppery depression, and a smaller 

 one a little above the apical third, near the sutui'e ; subsutural costa 

 entire from the apex forward to the anterior third, where it becomes 

 obsolete and joins the lower margin of the semicircular basal depres-

 sides more densely so; apical segment deeply emarginate in the mid-
