CERAMBYCID^E 323 



the last joint short, with constricted conical apex, the legs more 

 slender; thoracic punctures above and beneath extremely fine and 

 dense. Length (cf, 9) 18.0-22.0 mm.; width 4.8-6.1 mm. North 



Carolina (Southern Pines), Manee coquus Linn. 



A Similar but brownish-black, more slender in form, the elytral pale 

 spot always much smaller. Male with the antennae similar but 

 still more slender, very finely filiform apically, the last joint 

 scarcely one-half as thick as the third, the appendage feebly 

 differentiated; prosternal and pronotal punctures as strong but 

 distinctly separated, the interstices very finely, closely punctate; 

 abdominal punctures finer and less dense. Female much smaller 

 than the male, differing as in the same sex of the preceding. 

 Length (cf, 9) 16.0-21.0 mm.; width 4.5-5.5 mm. New Mexico 



(Las Vegas) and Texas filicorne n. subsp. 



B Similar in size to coquus but broader and rather less convex, 

 velvety-black, the elytra fulvous, blackish at the basal margin, 

 generally shaded with a slightly more obscure fulvous or brownish 

 tint outlining much the same extended maculation as in the female 

 of coquus; body much stouter and with relatively larger pro- 

 thorax than in filicorne, the antennae nearly similar, though not so 

 slender; vestiture of the almost similarly very densely punctate 

 pronotum much sparser. Length (cf, 9) 18.5-24.0 mm.; width 



5.5-7.2 mm. Texas fulvipenne Say 



C Smaller and much more slender than the preceding, with notably 

 shorter and very much more slender legs and more slender tarsi, 

 similarly colored and sculptured, except that the pale fulvous- 

 yellow elytra have each a brown cloud, truncate before the middle, 

 where it extends almost to the suture, thence receding posteriorly 

 but attaining the suture at apex; antennae very slender but rather 

 shorter, the outer joints especially more abbreviated. Length 



(cf ) 16.5 mm.; width 4.4 mm. Texas nubifer n. subsp. 



D Still smaller, slender, parallel, colored and sculptured throughout 

 nearly as in fulvipenne; antennae as in nubifer; legs still shorter, 

 slender, the tarsi notably shorter than in any of the preceding, the 

 posterior scarcely more than half as long as the tibiae; elytra much 

 shorter than in nubifer, but little more than twice as long as wide. 

 Length (cf) 14.8 mm.; width 4.0 mm. New Mexico (Las Vegas). 



levipes n. subsp. 



Hind tibiae inwardly bent toward tip; appendage of last antennal joint \ 

 in the male more arcuate than usual, with the tip gradually swollen 

 or subbulbiform. Body larger and stouter than in coquus or any 

 of the subordinate forms, the corneous processes between the an- 

 tennae more developed and the tarsi somewhat longer and stouter, 

 dull smoky-black throughout, the elytra each with a very minute 

 point of orange tint near the margin behind basal fourth; general 

 form and sculpture as in coquus, the vestiture shorter, thinner and 

 much less conspicuous; legs longer; prosternal punctures (cf 1 ) as 

 in the preceding forms, the antennae as in coquus but still more 

 elongate and with longer basal joint. Length (cf ) 26.5 mm.; width 

 7.3 mm. Texas apicatum n. sp.
