15. Prothorax with rather coarse punctures which are partly more 
or less confluent, between the punctures the surface more or 
less rugose; femora and tibiae more red than metallic neomexicana n. sp. 
Prothorax more or less distinctly strigate-rugose with or without 
punctures, which, when present, are always fine; legs more 
metallic than red diihia n. sp.

Moderately elongate; color generally rufo-cupreous, occasionally 
metallic green, rarely aeneous or purple; antennae and legs always 
entirely rufous; below entirely metallic with the last ventral segment 
more or less and apex of all segments reddish or metallic with one or 
more of the ventral segments reddish. 
Head rather' feebly prolonged, squarely truncate and distinctly 
constricted behind the eyes, which are prominent; surface shining, 
scarcely pubescent, moderately coarsely and densely punctate ; antennae 
short, not extending quite to the middle of elytra, second and third 
joints short, equal or subequal, frequently the third joint nearly as long as 
the fourth, the latter scarcely as long as the first joint. 
Prothorax as wide at apex as long or slightly longer; anterior angles 
distinct, occasionally more or less distinctly prominent; basal angles 
distinct, at most feebly prominent; lateral tubercle large, smooth, 
impunctate and feebly convex, generally separated from the disk by an 
arcuate, feeble impression, which is usually closely punctate; surface 
shining, sparsely punctate, occasionally a few small punctures are inter- 
mixed with the larger ones ; anterior impression absent ; posterior trans- 
verse impression very distinct; median line deeply impressed, moderately 
wide but occasionally faint or nearly absent. 
Elytra with ante-median impression distinct; post-median im- 
pression usually absent; serial punctures moderate, slightly finer towards 
apex; surface shining, generally smooth with at most a few transverse 
rugae, these latter occasionally a little more numerous in a specimen; 
intervals smooth or with very fine punctures especially in the basal 
region. 
Body below with moderate punctures which are generally well 
separated from each other by their own diameter, those of the two last 
^ The measurements are taken from the apical margin of prothorax to the apex of 
elytra. Only localities are recorded from which specimens have been seen.
