DESCRIPTION. 



1(51 



Body black, not glossy. Head minutely and thickly punctured, channelled, on each side of the 

 channel between the eyes is an impression ; antenna? nearly as long as the prothorax : prothorax 

 scarcely wider than long, channelled, with a large but shallow impression on each side ; sides thickly 

 punctured so as to resemble net-work ; rounded with the basilar angles depressed and a little diverg- 

 ing : scutellum nearly heart-shaped, acute : elytra rough with very minute and numerous granules, 

 and several very slight shallow impressions, between which runs an obsolete obtuse ridge from the 

 shoulder towards the apex, serrulated at the apex, and terminating in a very sharp point : breast 

 minutely and thickly punctured ; prosternum a little constricted in the middle, point triangular. 



LXXXIII. Genus AGRILUS. 



(215) 1. * Agrilus bivittatus. Two-striped Agrilus. 



A. (bivittatus) granulatus, supra niger, subtus aneus ; prothorace elytrisque vitta communi postice abbreviata, subaurata. 

 Two-striped Agrilus, granulated, above black; underneath bronzed; prothorax and elytra, with a pale golden stripe poste- 

 riorly abbreviated common to both. 



Length of the body 4 lines. 



Taken in Canada by Dr. Bigsby ; I also purchased a specimen, probably taken 

 in Georgia, at Mr. Francillon's sale. 



DESCRIPTION. 



Body subcylindrical, elongated and slender ; covered, especially above, with innumerable minute 

 granules ; upper surface black, lower bronzed-copper, glossy, hairy, especially anteriorly, with very 

 minute decumbent white hairs. Nose narrow, truncated anteriorly ; antennae bronzed : prothorax 

 nearly square, rather narrowest at the base ; sides slightly curving ; a double basilar sinus ; a rather 

 broad stripe formed of minute decumbent pale golden hairs covers each side of the prothorax, and 

 then forming a bend, runs along the disk of the elytra, tending towards the suture, becoming gra- 

 dually evanescent as it approaches the end of the elytra, which it does not reach : scutellum divided 

 into two portions by a transverse ridge, the basilar one transverse, and the apical triangular and 

 acuminated : elytra linear, constricted below the base, subacute and serrulated at the apex ; at the 

 base is a rather deep circular impression : exposed sides of the dorsal segments of the abdomen 

 thickly covered with white decumbent hairs : hypopygium entire.
