CERAMBYCID/E 315 



near the base and on the declivity, where they are sinuously cinereous, 

 the black fasciculi feeble and sparse, stronger at base, especially 

 on the first line; color obscure testaceous; antennae rufous, mottled, 

 the articular apices dark; prothorax twice as wide as long or very 

 nearly, the three dark spots feeble, the two anterior slightly swollen, 

 the sides subarcuately oblique before the minute and very acute 

 spine at basal third, the apical angles rounded; elytra strongly and 

 closely punctate, the sculpture partially concealed, the lateral dark 

 cloud invading the disk to outer third; apices feebly oblique, straight, 

 with broadly rounded external angles; femora strongly clavate, the 

 posterior less so in the female. Length (cf 9 ) 4.8-5.4 mm.; width 

 1.7-2.0 mm. Texas (Brownsville) texanus n. sp. 



Oblique fasciae strongly marked in the generally paler and denser cine- 

 reous field, but always widely broken submedially, the outer dis- 

 connected spot more advanced; body stouter, still more convex; 

 integuments dusky rufous, black in the large lateral elytral spot, 

 which invades the disk to outer third and on which the cinereous 

 hairs are sparser, thus greatly accentuating the blackness of the 

 spot; head feebly indented; antennae rufous, mottled, the articular 

 apices black, two-thirds longer than the body (cf) or one-half (9 ); 

 prothorax slightly less than twice as wide as long, the lateral pro- 

 jection at basal third large, dentiform, with a minutely acicular 

 apex, the surface dull, the dark spots feebly defined, brown; elytra 

 three-fourths longer than wide, the pubescence somewhat variegated, 

 broadly and indefinitely whitish and more tawny, the elevated lines 

 feeble, the fasciculate tufts small, black and rather numerous; 

 punctures coarse but not dense; femora all rather strongly and sub- 

 equally clavate in both sexes. Length (d 71 9 ) 4.8-5.8 mm.; width 

 1.8-2.25 mm. Texas (Brownsville and Austin). The Austin 

 examples are scarcely so stout and with relatively slightly smaller 

 head and prothorax, differing subspecifically houstoni n. sp. 



14 Body larger, stout, convex, densely clothed with .cinereous hairs, 

 shaded in certain areas with yellowish tint; integuments tawny- 

 rufous, darker in the lateral elytral spot, where the hairs are only 

 a little shorter and but slightly less dense than elsewhere; head 

 feebly indented; antennae nearly as in the preceding but longer, 

 three-fourths longer than the body ( 9 ) ; prothorax but little more 

 than one-half wider than long, otherwise nearly as in the preceding, 

 the three blackish spots not visible in the broad general mottling; 

 elytra three-fourths longer than wide, the oblique fasciae broken 

 exactly as in houstoni, the lateral spot paler brown and invading the 

 disk fully to outer third, the elevated lines distinct, with the fas- 

 ciculi very minute, brownish-black and sparse; apical truncatures 

 only feebly oblique, broadly and feebly sinuate, with sharply marked 

 angles; punctures coarse, not close-set; under surface with dense 

 and rather coarse cinereous and feebly, finely dappled vestiture, 

 longer and coarser than in houstoni; two anterior femora more 

 strongly clavate than in the female of houstoni but with the posterior 

 relatively less clavate. Length (9) 6.7 mm.; width 2.6 mm.
