OK THE COLEOPTERA J.ONGICORN1A OF THE UNITED STATES. 35 



Saperda unicolor, No. 781, and S. scutellata, No. 779, Mels. Cat. Antennae slender, basal articulation slightly 

 curved, frontal line impressed between them: prothorax with the sides projecting, and having a tendency to form 

 an angle in the middle: scutcl yellowish, concave: elytra sparsely clothed, the hairs arising from numerous 

 impressed punctures; tip obsoletely emarginate. 



Distinguished by its slender form, uniform tint, and slightly emarginate elytra.

 Coquus, Fabr., ii. 300. Melshcimeri, Germar Species. 



The transverse hand near tin; hasc of the elytra is sometimes interrupted at the suture 

 so as to leave two fulvous spots. Professor Germar (Revue Zool., 1S39, p. 330,) refers 

 his specimen to the genus Anoplistcs, Serv., Ann. Ent. Soc, France, ii. 570, probably 

 because the armature of the prothorax cannot be readily distinguished through the i\cn<f 

 clothing of hair.

:!7. C. aorestis, Kirby. (Callidium.) N. Z. 170. 



Dull brownish-black, beneath black with cinereous pubescence; pronotum with three conspicuous fovea?. 



10" long; 2 wide. Inhabits Maryland and Virginia. 



Criocephalum foveicolle, Dejean Cat., p. 354. Head with a deeply impressed line between the antennae: pro- 

 notum Battened; posterior two-thirds of the dorsal line impressed, and spreading laterally so as to form a wide 

 furrow, somewhat foveolate near the posterior margin; a large conspicuous fovea or indentation upon each side of 

 the dorsal line and lateral limb, and a slight inconspicuous impression in the posterior angles: elytra with three 

 longitudinal ribs; one medial, the second intermediate between this and the suture, ami the third submarginal ; 

 the marginal space being narrowest, and the submarginal one widest; the outer and inner costx curve towards 

 each other and meet near the apex of the elytra, and near this angle the medial costs curves to the inner one; a 

 very short, obsolete, subsutural costa joins the scutel. 



38. C. rusticus, Fabr. C. obsoletum, Kundall. 



Dorsal marks and elytral costa; obsoleto, scutellar costs? upon the suture.

Black, finely scabrous; elytra striate, with the intervals elevated into costa?. 



6 long; 1| wide. Inhabits Pennsylvania. 



Head finely punctured, a wide indentation between the antenna:: prothorax brownish pubescent; with a wide, 

 faint, dorsal fovea: elytra with two approximate elevated medial costs', meeting posteriorly, an indistinct one 

 between these, another upon the suture, and a submarginal one obsolete anteriorly: scutel with a medial im- 

 pressed line.
