narrower than the head, of the usual strongly biconstricted, laterally 

 prominently rounded form, finely, rather closely punctate; elytra 

 more coarsely and closely punctate than in scripta, less coarsely, 

 though distinctly, apically than basally. Length (cf) 7.6 mm.; 



width 2.1 mm. West Virginia aurata Horn 



Elytra with the median vitta narrow, the ground color black 3 



3 Head scarcely at all impressed transversely. Body black, shining; 

 legs pale, the tip of the hind femora black; antennae ( 9 ) very slender, 

 piceous, testaceous basally, three-fourths as long as the body, the 

 third joint not longer than the first; head not quite as wide as the 

 prothorax, the tempora less prominent than the eyes as usual but 

 nearly parallel, rounded basally, finely, sparsely punctate through- 

 out; prothorax shorter than usual, not as long as wide, the lateral 

 prominences subangulate; punctures fine and sparse but distinct; 

 basal constriction prolonged anteriorly along the median line for a 

 short distance; elytra shorter than usual, but little more than twice 

 as long as wide, parallel, very obtuse at apex, the apices rounded, 

 black, each with a discal yellow vitta and pale margin from the base 

 to apical fourth, the punctures deep and coarse but well separated, 

 smaller apically; abdomen pale, clouded with piceous, finely, rather 

 closely punctulate. Length (9) 6.8 mm.; width 1.8 mm. Wis- 

 consin (Bayfield), W'ickham lineicornis n. sp. 



Head more or less deeply impressed transversely between the eyes.. .4 

 4 Tempora nearly parallel behind the eyes, rounding at base. Body 

 black, the surface polished; legs and antennae as in the preceding, 

 except that the latter ( 9 ) are longer, being as long as the body and 

 with the third joint one-half longer than the first; head almost 

 impunctate; prothorax scarcely as wide as the head, longer than 

 wide, very convex, the sides strongly, evenly inflated medially, not 

 at all anguliform; basal constriction feeble discally, not at all pro- 

 longed medially; punctures extremely minute and sparse; elytra 

 more elongate, nearly two and one-half times as long as wide, parallel, 

 rounded at the tips, black, each with a yellow vitta which is broad at 

 base, gradually narrowing and disappearing before the middle, the 

 pale lateral edge disappearing posteriorly; punctures moderate, 

 deep and perforate, separated basally by nearly twice their diameters; 

 abdomen pale, the basal segments black at the sides basally. 

 Length (9) 8.0 mm.; width 2.3 mm. Wisconsin (Bayfield), - 



Wickham laeviceps n. sp. 



Tempora converging behind the eyes; elytral vitta much longer. Body 

 and abdomen black throughout, the legs as in the preceding; an- 

 tennae (9 ) piceous-black, very slender, nearly as long as the body; 

 prothorax elongate, a little narrower than the head, the sides 

 prominent before the middle; punctures fine and sparse but distinct; 

 elytra fully two and one-half times as long as wide, parallel, more 

 coarsely and closely punctate than in the preceding, the punctures 

 basally separated by their own widths, the discal yellow stripe almost 

 attaining the apex, near which it is frequently dilated almost to the 

 suture. Length (9) 8.4 mm.; width 2.3 mm. Pennsylvania.
