NORTH AMERICAN COLEOPTERA. 113 



twice as wide as long, widest slightly behind the middle, sides sit apex and base 

 narrowing, at middle slightly sinuate : disc moderately convex, without well 

 marked depressions, except the usual post-apical, surface coarsely punctate, the 

 punctures rather close at middle and sometimes transversely confluent, at sides 

 much more dense ; elytra wider than the thorax, gradually wider to two-thirds, 

 then arcuately narrowing to apex, the margins serrate, the apices obtuse ; disc 

 feebly convex, a faint trace of the first costa and barely pei-ceptible smooth lines 

 indicating the others, the basal fovea small but distinct, two discal fovese, one in 

 front of middle, the other one-third from the apex, the foveae often brighter blue 

 or green; surface coarsely punctate, not closely in apical half, more densely near 

 the base ; body beneath more shining than above, usually blue, rarely green, 

 these latter with the sides bright cupreous, as in sexsignata, the surface rather 

 sparsely punctate ; prosternum scarcely perceptibly lobed in front ; anterior femur 

 with a rather broad tooth, serrulate on its distal edge ; last ventral segment with 

 entire margin. Length .24- .31 inch ; 6- 8 mm. (Fig. 217.) 



Male. — Prosternum densely, coarsely punctured over its entire surface ; ante- 

 rior tibia (221) arcuate, thicker to tip, but not dilated at apex ; middle tibia 

 slightly arcuate, the posterior straight ; last ventral segment (219) deeply, semi- 

 circularly emarginate, the angles acute, a slight carina at middle posteriorly. 



i^emrt/c — Prosternum a little less densely punctured ; anterior and middle tibiae 

 slightly arcuate, the posterior straight; last ventral (220) truncate, with the 

 angles acute and prominent, slightly carinate, at middle posteriorly. 



This species from its variable color might be confounded with 

 Hai-risii or .^cihila, but the structure of the antennae will distinguish 

 it from the first, and of the thorax from the second. In one speci- 

 men I have seen the suture of the elytra is greenish metallic. 



Occurs in New York, Illinois, District of Columbia, Georgia and 

 Texas. 



45. €\ teueola Lee — Form rather broad, subdepressed, nearly as in jjusiUa, 

 dark bronze, subopaque ; front slightly convex in both sexes, coarsely punctured, 

 a little more closely in the male, the female with two faint chevrons, dark 

 bronze 9 > slightly greenish % ; antenufe rather broad, gradually more slender to 

 the tip, the third joint not as long as the next two ; clypeus (223) acutely emar- 

 ginate at middle arcuate each side, closely resembling femorntn ; thorax a little 

 more than twice as wide as long, narrowed in front, sinuate at the middle of the 

 sides, incurved posteriorly ; disc feebly convex, a vague median sulcus, a deeper 

 depression near the sides ; surface moderately and coarsely punctate, slightly 

 transversely confluent in the female ; elytra scarcelj^ wider than the thorax, par- 

 allel, narrowed at apical third, the margin feebly serrulate, the apices obtuse ; 

 disc subdepressed, basal fovea moderate, a longer humeral depression, first co.sta 

 slightly elevated from apex one-third to base and continued slightly by a smooth 

 line, the other costa faintly indicated by short lines ; surface moderately, densely, 

 equally punctured without distinct fovese ; body beneath much more shining than 

 above, the punctures of the abdomen rather sparse and indistinct ; last ventral 

 segment with entire margin ; prosternum not lobed in front ; anterior femur 

 with a moderate tooth not serrulate on its margin. Length .27 inch ; 7 mm. 

 (Fig. 222.)
