STUDIES IN THE AMERICAN BUPRESTID^ 75 



not much more so laterally, the finely punctate shallow areolae rather 

 small in size, frequently subtransversely coalescent; presternum densely, 

 coarsely punctate, broadly polished and impunctate along the middle; 

 legs blue, the femora frequently subviolaceous. Length 26.0-28.8 

 mm. ; width 10. 2-1 1.6 mm. Texas (El Paso) convexa n sp. 



Antennae probably metallic blue in color but not described, the body nearly 

 as in convexa but with the prothorax very much more transverse, the 

 form stout, the color dark steel-blue, the head and prothorax with 

 greenish-brassy punctures, the latter unequally punctate, at the middle 

 basally broadly foveate, almost three times as wide as long, broader 

 before the base, the sides anteriorly strongly rounded, posteriorly 

 sinuate, the hind angles right; elytra with punctured striae, the inter- 

 vals with many quadrate spaces, which are impressed, greenish-brassy, 

 granulate and pubescent, at the apex obUquely subtruncate, the sutural 

 angles rather prominent; under surface densely and coarsely viridi- 

 punctate; presternum bisulcate. Length 22.5-28.7 mm. Texas 

 (Eagle Pass, — LeConte). [=Psiloptera valens 'Lee] valens Lee. 



Antennae non-metallic, except sometimes feebly toward base 4 



4 — Body stout, parallel and convex, nearly as in convexa and valens in color- 

 ation, lustre and sculpture throughout, the eyes larger, much more 

 prominent and less vddely separated than in the former; antennae simi- 

 lar but deep black, becoming faintly bluish toward base; prothorax 

 shorter than in convexa, apparently somewhat more than twice as wide 

 as long and of a different outline, being more anteriorly inflated and 

 widest before the middle laterally, more sinuate basally, the angles 

 similar, the basal impression more extended anteriorly, obsolescent 

 beyond the middle; elytra nearly similar but scarcely more than three- 

 fourths longer than vnde, the apical truncature oblique, angularly acute 

 and prominent suturally, the aeneous areolae larger, the punctures of 

 the series toward the suture smaller; under surface nearly similar, 

 the tibiae rather more closely punctate and pubescent, the abdomen 

 with large and uniform dense patches of pubescence laterally. Length 

 23.5-24.5 mm.; width 9.2-9.8 mm. Western Texas (locality unre- 

 corded) ocularis n. sp. 



Body more slender, parallel, convex, very much smaller in size, shining, 

 almost similarly sculptured; head small, black, with coarse aeneous 

 rugae, the eyes moderate, not notably prominent; antennae short, piceous- 

 black throughout; prothorax black, convex, three-fourths wider than 

 long, only moderately and gradually narrowed anteriorly, widest near 

 basal third, the sides very broadly rounded, becoming sinuate only at 

 the basal angles, the surface deeply and rather abruptly impressed 

 at the middle basally, the punctures very coarse, not close, aenescent 

 and irregular; elytra blackish-blue, in form and sculpture nearly as in 

 the preceding species, the apices more narrowly and obliquely truncate; 

 under surface nearly similar, except that the more densely and evenly 

 pubescent sublateral patches of the abdomen are much more finely 

 and feebly sculptured; legs and tarsi more slender, blue, the femora
