twice as wide as the prothorax; stris not very fine and slightly 

 uneven, the intervals evidently though not strongly convex, the

Texas (Austin) smaragdula Dej. 



Body slightly broader, the head relatively not quite so large, shining, 

 bright green, the anterior parts sometimes subaeneous and the elytra 

 partially bluish; under surface with dark bluish-green lustre; head 

 slightly elongate, evidently narrower than the prothorax, with large 

 but only slightly prominent eyes; front minutely, sparsely punctu- 

 late, finelv strigilate postero-laterad ; antennae half as long as the 

 body, slender; prothorax relatively a little larger than in the pre- 

 ceding and nearly three-fourths wider than long, almost similar in 

 form and sculpture, but with the median line finer; elytra a third 

 longer than wide, oblong, only feebly dilated posteriorly and barely 

 more than twice as wide as the prothorax; striae much less fine 

 than in viridis, feebly impressed and, at least toward the sides,

Tucker papago n. sp. 



A— Similar to papago but with the head, though slightly elongate, 

 scarcely visibly narrower than the prothorax, the latter not quite 

 so transverse; elytra narrower and more elongate, fully two- 

 fifths longer than wide, the stri^ stronger, more impressed, more 

 punctate and irregular, the intervals feebly convex and more 

 strongly micro-reticulate than usual; abdomen similarly with 

 very small sparse hairs. Length 4.0 mm.; width 1.8 mm. Ari-

 the prothorax, nearly smooth; antennae slender, fully half as long 

 as the bodv; prothorax small, two-thirds wider than long, the 

 sides a little more converging before and behind the middle than in 

 either smaragdula or papago, similarly reflexed; rugulosity extremely 

 fine and faint, the median stria fine; elytra two-fifths longer than 

 wide, evidently inflated posteriorly, much more than twice as wide 

 as the prothorax; striae not very fine, irregularly subpunctulate and 

 distinctly impressed; intervals very obviously convex, the dorsal
