CERAMBYCID^E 295 



three to five better developed, rapidly diminishing, that of the third 

 joint nearly two-fifths as long as the fourth joint, third joint nearly one- 

 half longer than the fourth; scutellum rounded behind, moderately 

 densely clothed with very short pallid hairs; elytra rather more than four 

 times as long as the prothorax and more than one-half wider, perfectly 

 parallel, the punctures rather small and well separated even basally, 

 the apices as in the preceding, the fifth ventral more broadly and arcu- 

 ately truncate; legs very slender, the femora not spinose; abdomen uni- 

 formly and somewhat strongly punctate and feebly pubescent throughout. 

 Length (cf) 14.0 mm.; width 2.9 mm. California (Siskiyou Co.), 

 Koebele. 



The elytral pubescence is decumbent, sparse, even and unmixed 

 with erect hairs of any kind. It is much larger than linearis Lee., 

 to which it may be allied, differing besides in the almost complete 

 extinction of anything that could be called a posterior thoracic 

 callus, there being simply the remains of a very narrow impunctate 

 median line just behind the centre; the elytral punctures also 

 seem to be smaller; linearis is from the southern part of the state. 



*Aneflomorpha unispinosa n. sp. Similar in its very elongate and 

 narrow, parallel form but less testaceous and more piceous in color 

 throughout, the vestiture of whitish hairs decumbent, scanty and un- 

 mingled with erect hairs; head wider than the apex of the prothorax, very 

 densely punctate, the eyes separated by only three-fifths their width; 

 antennae (cT) very slender and filiform, evidently longer than the body, 

 the spines small, the dorsal carina very strong and clearly defined on the 

 subbasal joints, the fourth joint much longer than the first; prothorax 

 elongate, fully a fourth longer than wide, cylindric, very feebly and ob- 

 tusely subprominent at the sides well behind the middle, the punctures 

 very coarse, densely confluent throughout, with a very small elongate 

 impunctate median line behind the centre; scutellum rounded, densely 

 and pallidly pubescent; elytra about four times as long as the prothorax 

 and two-thirds wider, rectilinear, the apices each with a very small feeble 

 sinus, which is limited by a long spiniform sutural projection and a very 

 broadly obtuse lateral angle; punctures basally very moderate but deep, 

 separated by two to nearly three times their diameters and with not 

 more than half the diameter of the thoracic punctures, becoming fine 

 and rather sparser apically nearly as in longipennis but not so noticeably 

 so as in subpubescens and especially in seminuda; legs slender, the femora 

 mutic, the fifth ventral (cf) sinuato-truncate. Length (c?) 16.5 mm.; 

 width 3.2 mm. Mexico (Colonia Garcia, Chihuahua), Townsend. 



Differs from the two preceding and subpubescens in its rufo- 







piceous color, more slender and relatively even more coarsely 

 punctured prothorax, longer antennae, in the elytral apices and the 

 fine strong dorsal carina of the antennal joints almost throughout 

 but becoming much stronger on the subbasal joints.
