STUDIES IN THE AMERICAN BUPRESTIDiE lOI 



but unevenly punctate, with sublateral smooth spaces and a narrow 

 and uneven impunctate median line; elytra long, but little wider than 

 the thoracic disk, twice as long as wide, the subparallel sides very 

 gradually rounding and oblique posteriorly, the aj)ices rounded, with 

 the sutural angle scarcely at all prominent; surface with the intervals 

 alternatingly feebly and strongly convex, moderately punctate, rather 

 coarsely and closely so and subrugose laterally; abdomen deeply and 

 abruptly sulcate basally, rather strongly but sparsely punctate, the 

 yellow spots distinct and subequal on every segment, larger and trans- 

 verse though separated on the fifth. Length (9) 19.5 mm.; width 

 7.0 mm. New Mexico (Cloudcroft) acomana n. sp, 



Prothorax not so strongly narrowed and less rounded on the sides, the apex 

 three-fourths to four-fifths as wide as the maximum width; elytral 

 apices similar 25 



25 — Elytra oblique at the sides in fully apical two-fifths, more prolonged 

 apically, the eyes rather more prominent. Body oblong, rather de- 

 pressed, deep black; head (9) coarsely rugose, with a large median 

 area somewhat depressed and with a short callous median line, finely 

 and densely punctate, the front wdth four anterior pale spots; epistoma 

 medially unusually deeply sinuate; antennae rather thick; prothorax 

 short, almost twice as wide as long, the sides converging, evenly and 

 moderately arcuate from just before the base to the apex, rounding 

 in slightly at base; apex and base broadly bisinuate; surface coarsely 

 and irregularly punctured as usual, the smooth median line with a 

 striaform impression at base; scutellum longer than wide, metallic; 

 elytra not quite twice as long as wide, scarcely at all wider than the 

 prothorax, with the usual nearly flat, alternating with convex, intervals, 

 the flat ones much the broader; punctures fine and sparse; abdomen 

 rather strongly and closely punctate but not coarsely, the basal sulcus 

 moderate, not quite attaining the apex of the first ventral; spots red, 

 those of the fifth segment transversely subquadrate, widely separated. 

 Length (9) 18.0 mm.; width 7.0 mm. Kansas morosa n. sp 



Elytra generally oblique in about apical third; eyes not prominent 26 



26 — Form rather more elongate and scarcely so depressed, black, sometimes 

 with very faint greenish or violaceous lustre either on the elytra or 

 pronotum, the former frequently dark piceous; head nearly as in morosa 

 but with more yellow maculation, this sometimes solidly surrounding 

 the median parts of the front though broadly open behind, the epistoma 

 less deeply sinuate, the antennse rather longer; prothorax much less 

 transverse, three-fourths wider than long, the sides frequently a little 

 more rounding basally, the sculpture coarse, nearly similar; elytra 

 nearly similar, though a little more elongate and more evidently wider 

 than the prothorax, the punctures larger, closer and much more con- 

 spicuous especially laterally; abdomen as in morosa, the pale spots 

 of the last segment rarely coalescent transversely; male apparently 

 very rare. Length (9) 17.0-20.0 mm.; width 6.6-7.8 mm. Col- 

 orado,— Cab. Levette fusca n. sp.
