CERAMBYCID^: 361 



feebly tumid and very obtusely angulate, densely cinereo-pubescent. 

 Length (9 ) 8.5-9.2 mm.; width 2.4-2.6 mm. Texas (Harris Co., 

 R. Oertel, and Austin, Csy.) cineracea n. sp. 



Body above less densely clothed with finer, shorter, more fusco-cinereous 

 pubescence, the sutural margins densely pale cinereous or yellow. .3 



3 Prothorax even in convexity and surface, with small sparse punctures 

 and trivittate with dense yellowish pubescence, having no trace of 

 callous spots; antennae slender, blackish, very evenly and inconspicu- 

 ously clothed throughout with small fuscous hairs, the fringe coarse, 

 moderate in length and sparseness; elytra coarsely and rather closely 

 punctate, the punctures only a little smaller near the apices, which 

 are evenly and broadly rounded; epipleura densely yellow-cinereous. 

 Length (9) 7.2-8.3 mm.; width 1.7-2.0 mm. Texas and New 

 Mexico marginalia Lee. 



Prothorax more evidently transverse, not vittate but with five small 

 shining callous spots; antennae much thicker, the joints annulate 

 with cinereous in nearly their basal halves above, entirely cinereous 

 beneath; elytra sparsely, rather strongly punctate, much more finely 

 toward the apices, which are evenly rounded, black, with fine yel- 

 lowish-cinereous internal and external margins, the surface medially 

 pallescent in the female, except laterally and basally. Length 

 (a 71 9 ) 9.2-11.0 mm.; width 2.5-3.0 mm. Kansas and New Mexico.

4 Body black, stouter, densely clothed throughout with uniform cinere- 

 ous pubescence, the pronotum with two very small callous glabrous 

 spots; elytra broadly and evenly rounded at the apices 5 



Body narrower, unequally clothed, black, the head and prothorax in 

 great part testaceous; elytral apices sharply angulate, being obliquely 

 sinuato-truncate thence to the suture 6 



5 Form subcylindric, very densely clothed with luteo-cinereous ves- 

 titure, the erect hairs rather short, numerous but cinereous; head fully 

 as wide as any part of the prothorax, convex; antennae (9 ) a little 

 shorter than the body, not annulate, clothed throughout beneath 

 with pale ashy, and in great part above with dark brown, hairs, 

 the fringe distinct; prothorax subcylindric, with but very feebly 

 arcuate sides, almost as long as wide; elytra distinctly wider than the 

 prothorax, parallel, abruptly and broadly rounding behind, the 

 punctures nearly concealed but moderate in size and sparse; fifth 

 ventral (9) feebly impressed and deflexed apically, the medial 

 stria fine and not distinct much beyond the middle, the pygidium 

 feebly, evenly and broadly convex, densely cinereous, the apex very 

 feebly and broadly angulate. Length (9) 13.5-14.0 mm.; width 

 3.6-3.8 mm. Kansas saturnina Lee. 



Form shorter, similarly densely clothed but with paler yellowish pubes- 

 cence, almost concealing the small sparse punctures, the erect hairs 

 extremely short, scarcely discoverable on the elytra and cinereous; 

 head not as wide as the middle of the prothorax, the antennae dis- 

 tinctly shorter than the body, shorter than in the preceding species, 

 clothed throughout beneath with cinereous pubescence and above 

 by a mixture of cinereous and brown, the latter predominating toward
