tures are, however, subeffaced in a transverse and feebly reflexed 

 line at the usual position of the pale median band o^ purpurea. 



The following species may be placed near purpurea for the 

 present : 



C. denverensis n. sp. — Smaller, narrower and more elongate thanpw- 

 ^itrea; body pale and vivid emerald green throughout, without trace of cop- 

 pery reflection and with barely a trace of bluish tinge along the elytral mar- 

 gins. Htad with erect white vestiture, especially dense as usual on the 

 frontal declivity ; labial palpi with the second joint pale ; labrum tridentate. 

 Proihorax less than }4, wider than long, distinctly narrower than the head ; 

 impressed lines deep ; surface minutely and densely vermiculato-rugose ; 

 pubescence long and erect at the sides. Elytra oblong, '^4, longer than wide, 

 the sculpture and markings as in purpurea, except that the middle transverse 

 dash is reduced to a small transverse spot near the lateral margin ; apical 

 lunule incomplete. Length 11.0 mm. ; width 4.6 mm. 



Colorado (Denver). 



Abundantl}^ distinct from the other forms which are more or 

 less closely related to purpurea, by its elongate outline, pale 

 second joint of the labial palpi and other characters. From 

 pusilla it differs in its entirely dark tibias and complete absence 

 of any form of humeral marking. The first three joints of the 

 anterior male tarsi are narrowly and subequally dilated, the third 

 joint more than twice as long as wide. 



C depressula n. sp. — Moderately stout, somewhat depressed, feebly 

 shining, bright green, the head and prothorax in part with h feeble coppery 

 reflection ; humeral lunule generally wanting, sometimes represented by a 

 small spot near the basal fourth, not extending to the margin ; post-median 

 transverse spot slender, feebly dilated at its extremities, strongly reflexed and 

 attaining posterior third near the suture, not attaining the margin ; apical 

 lunule represented by two small detached spots. Head moderate in size, mi- 

 nutely strigato-rugose, the front not at all pubescent ; labrum short and trans- 

 verse, nearly 3 times as wide as long, imperfectly tridentate, the lateral teeth 

 in the form of feeble arcuations, and sometimes virtually obsolete ; antennae 

 slender, moderate in length ; labial palpi pale, the apical joint black. Pro- 

 thorax fully as wide as the head, % wider than long, minutely and densely ru- 

 gose, the impressions deep and of a dark violet blue ; pubescence sparse and 

 only partially erect at the sides. Elytra oblong, gradually slightly wider be- 

 hind, scarcely }4 longer than wide, the intrahumeral impression distinct ; 

 punctures coarse, deep, moderately close, nearly uniformly distributed, slightly 

 asperate and tinged with a cobalt reflection. Legs metallic green, the tro- 

 chanters black. Length 12.0-14.0 mm.; width 4.7-5.4 mm, 



California (Placer Co.). 



May be placed near senilis, differing in coloration, in its stronger
