smooth elytra; but it will be founci upon a close inspection, i speak, 

 with regard to the American specimens, to exhibit several. 



Body black-bronzed, covered all over as it were with a fine net-work, 

 produced by minute lines as if scratched by a pin or needle ; above dull, 

 below glossy. Antennae much shorter than the prothorax : prothorax 

 transverse with rounded sides, and longitudinal basilar impressions near 

 each posterior angle : scutellum triangular : elytra with three very slight 

 impressions arranged longitudinally ; an obsolete series of punctures runs 

 parallel with the lateral margin ; apex obtuse and very minutely serrated : 

 prosternum acuminate. 



2x4. BuPRKSTis (Oxvn'ERis) APPENDicuLAfA Fabr. — Length of body 

 4/i — 5/^ lines. Several specimens in the Rocky Mountains,- and near 

 Cumberland-house. 



[161.] Body black, not glossy. Head minutely and thickly punctured, 

 channelled, on each side of the channel between the eyes is an impression ; 

 antennae 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 diverging : 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 ter- 

 minating in a very sharp point : breast minutely and thickly punctured ; 

 prosternum a little constricted in the middl?, point triangular. [Though, 

 as Le Conte remarks, this species here described is very closely related to 

 the European insect to which it is referred by Kirby, it is Says' Melano- 

 phila longipes — a species not at all uncommon in Ontario, and taken also 

 in such widely separated localities as Pennsylvania, Kansas and Lake Su- 

 perior.] 



215. Agrilus bivittatus Kirby. — Length of body 4 lines. Taken 

 in Canada by Dr. Bigsby. 



[Previously described as Buptesiis ( Agrilus) hilincatus Weber ; for 

 description vide Say's Ent. Works, i. 386 and ii. 596. This very pretty 

 species is not uncommon in Canada, and is taken throughout the United 

 States.] 



[162.] 216. Trachvs aurulexta Kirby. — Length of body 3 lines. 

 Taken in Canada by Dr. Bigsby. 



Body obovate, black-blue, glossy. Sinus of the head deeper than in 

 the other species ; face nearly covered with glittering copper-coloured
