CERAMBYCID.E 237 



surface black, the abdomen entirely pale testaceous; head fully two- 

 thirds as wide as the prothorax, the parallel and scarcely arcuate 

 tempora about as prominent as the eyes, which are rather convex 

 and separated by nearly their own width, the antennae dark casta- 

 neous, very stout basally, well developed, the last joint (cT) four 

 times as long as wide, very gently beveled apically, with a central 

 pit at the summit of the slope and fully as long as the preceding; 

 prothorax short, much more than twice as wide as long, broadly 

 sinuate at apex, feebly arcuate at base, the median tooth very acute, 

 hamate, the sides of the apex anteriorly prominent but rounded, 

 thence posteriorly oblique and straight to the apex of the acute 

 anterior teeth; punctures sparse but rather strong; scutellum very 

 obtuse; elytra fully a fourth wider than the prothorax, the sides 

 rather strongly converging and unusually feebly arcuate to the 

 obtusely rounded apex, the raised lines almost obsolete, the punc- 

 tures fine but deep, everywhere widely separated; close coarse pubes- 

 cence of the metasternum sparse at the centre, the hind tarsi with a 

 rather narrow but deep and even canaliculation throughout, rep- 

 resented on the middle tarsi by a very fine and barely visible stria. 

 Length (cf) 43.0 mm.; width 15.8 mm.; length of prothorax 5.7 

 mm.; width of head 8.3 mm. Arizona, Levette (locality unre- 

 corded) alutaceus n. sp. 



9 Body oblong, subparallel, rather depressed, deep black throughout, 

 the abdominal segments dark testaceous, black basally; surface 

 shining; head rather small, but little more than half as wide as the 

 prothorax, the tempora parallel, about as prominent as the eyes, 

 which are somewhat convex and separated by barely more than 

 their own width, the median sulcus of the front unusually large and 

 deep; antennae (9) deep black, except very near the apex, the last 

 joint rather small, but little more than twice as long as wide and much 

 shorter than the preceding, parallel; prothorax short, two and one- 

 half times as wide as long, very finely, sparsely and irregularly 

 punctate, the middle teeth unusually long, very acute, barely at all 

 recurved, the apex throughout nearly as in the preceding; scutellum 

 very obtuse; elytra barely three-fifths longer than wide, about a 

 fifth wider than the prothorax, the sides nearly straight and sub- 

 parallel, arcuate and converging in about apical third, rugosely 

 but not strongly or densely sculptured, the two inner raised lines 

 distinct; metasternum and tarsi as in tristis, except that the second 

 joint of the hind tarsi is much more rapidly narrowed from apex to 

 base, the canaliculation conspicuous and equally distinct on the 

 middle and posterior. Length (9) 43.0 mm.; width 17.0 mm.; 

 length of prothorax 6. o mm. ; width of head 7.4 mm. New Mexico 

 (Jemez Springs), Woodgate tetricus n. sp. 



10 Form stout, oblong, subparallel, convex, shining, rather pale rufo- 

 castaneous throughout, the head blackish, the prothorax nearly 

 so; head large, the parallel tempora swollen and more prominent 

 than the eyes, which are separated by a little more than their width; 

 antennae ( 9 ) unusually slender, the outer joints narrower and less 

 serrate than in any other species, the last joint fully three times as
