LXXXIV. Genus TRACHYS. Fab. 



(216) 1. * Trachys aurulenta. Aurulent Trachys. 



T. (aurulenta J nigro-caruleus, nitidus ; capite bilobo ; elytris subtrinerviis, maculis cupreo-auratis, fasciisque argenteis. 

 Aurulent Trachys, black-blue, glossy ; head bilobed; elytra obsoletely three-ridged, spotted with golden-copper, and banded 

 with silver, hairs. 



Length of the body 3 lines. 



Taken in Canada by Dr. Bigsby. There were also specimens in the late Mr. 

 Francillon's cabinet, probably taken in Georgia by Mr. Abbot. 



This may possibly be F. tesselata of Fabricius, but his description of that species 

 is so short, omitting many of the characters of the insect before us, that it appears 

 best to consider it as distinct. 



DESCRIPTION. 



Body obovate, black-blue, glossy. Sinus of the head deeper than in the other species; face 

 nearly covered with glittering copper-coloured decumbent hairs; antennas shorter than the prothorax: 

 prothorax transverse, repand on each side at the base with a central lobe, concave at the apex; 

 anteriorly in the middle very convex; sides and base depressed; surface impunctured and tesselated 

 with ruddy-copper hairs like those of the head : scutellum at the base transverse, with the vertex 

 terminating in a long and sharp acumen : elytra with three ridges, the two inner ones less distinct, 

 parallel, obtuse and abbreviated at each extremity, the external one distinct, acute running from the 

 shoulder in an undulated line nearly to the apex of the elytrum ; several rows of larger punctures 

 are discernible, and several spaces thickly punctured with minute ones ; the elytra are also spotted with 

 several hairy ruddy-copper spots, and ornamented with four or five undulated hairy indistinct silver 

 bands : underneath the tint of blue is very faint and the disk of the breast is bronzed : the mesos- 

 ternum is hollowed out into a deep channel. 



(217) 2. * Trachys acuducta. Acuducted Trachys. 



T. (acuducta J ublonga, cuprea, nitida, frontc retuso ; setulis squamuliformibus incana; prothorace transverse acuducta.
