CERAMBYCID/E 357 



2 Female black, with feeble brownish tinge, the pubescence throughout 

 extremely short, close but inconspicuous; antennae simple, not quite 

 one-half as long as the body, the outer joints rapidly very short, the 

 last less than one-half longer than wide; prothorax transversely oval, 

 evenly rounded, convex, nearly as wide as the elytra, briefly tubulate 

 at base, wholly immaculate, minutely, confusedly and densely sculp- 

 tured, with an indefinitely rounded discal area near outer fourth 

 more coarsely and less closely punctate; scutellum large, semicircular, 

 of the general dark ground color; elytra twice as long as wide, with 

 the densely pubescent sulphur-yellow marking very sharply defined, 

 consisting on each of a transversely oval subbasal spot, a small 

 marginal one at basal fourth or fifth, a perfectly circular discal spot 

 nearer the suture than the margin and just behind basal fourth, a 

 fine transverse entire and slightly arcuate fascia just behind the 

 middle and another suboblique fascia, broken into two spots, be- 

 tween the latter and the apex, which is not pale, minutely, obliquely 

 and simply truncate; under surface clothed with minute plumbeous 

 hairs, scarcely at all variegated, the prosternum more shining and 

 transversely rugose. Male more slender than the female, black, 

 the elytra paler, red-brown, dull in lustre like the female, the an- 

 tennae a little more than half as long as the body, the prothorax 

 similar but fully as wide as the elytra and having a slender longitu- 

 dinal crescent at lateral fifth, which is very sharply defined and more 

 coarsely sculptured though not elevated; elytra similar throughout 

 but rather more tapering and either wholly immaculate or with 

 very minute yellow points, representing one or more of the large 

 yellow spots of the female; under surface, prosternum and legs 

 nearly similar. Length (c?) 17.5-22.0, (cf) 22.0 mm.; width (c?) 

 5.3-6.8, (9) 6.9-7.2 mm. North Carolina, New Jersey, Indiana 

 and Wisconsin nobilis Say 



Female nearly as in nobilis, except that the spot between basal fourth 

 and third on each elytron is invariably transverse and rectangular 

 and not circular, and the apex more or less yellow 3. 



3 Female larger and more elongate than in nobilis, similarly colored and 

 with densely dull integuments; antennae nearly similar but not deep 

 black; prothorax of like form but more transverse and about as 

 wide as the elytra, the fine, confusedly punctato-rugulose sculpture 

 nearly uniform throughout; elytra a little longer, almost similarly 

 maculate with spots and fasciae of dense sulphur-yellow pubescence, 

 except as above stated and in having the ante-apical fascia entire and 

 not resolved into two spots and in having the apices almost solidly 

 yellow, only the actual tip dark, also with a longer oblique truncature, 

 with well marked external angle; under surface with very short uni- 

 form plumbeous pubescence, the apices of the ventral segments more 

 distinctly yellow laterally and the prosternum more coarsely and 

 densely rugose than in nobilis; legs longer, rufescent and not black. 

 Male with the prothorax as in the female, the sinuous sublateral 

 line of coarser sculpture barely traceable; elytra less elongate, paler 

 red-brown, with the transverse spot near basal fourth much reduced, 

 the fine median fascia feeble, faint and nubilous, the ante-apical
