tata and splendida — are undoubtedly entirely valid as species. 

 Gimarrona is more elongate in bodily form than purpurea, and 

 is probably a distinct species, very variable within itself in ground 

 color and degree of marking. Limhalis Klug, from which limha- 

 lis Lee. does not differ perceptibly, is a very distinct and constant 

 subspecies, in which the median band reaches the margin without 

 the least tendenc}"^ to spread longitudinally in any example known 

 to me. Graminea Schpp., is also a good subspecies, generally 

 above the average in point of size. The following are two addi- 

 tional subspecies of the purpurea type which do not seem to 

 have been alluded to hitherto : — 



C. lauta. — Similar in form to purpurea, bnt still shorter and a little more 

 depressed, green, the head and prothorax with a slight coppery reflection, the 

 legs polished, metallic and paler green, the elytra dull, of a deep and very rich 

 sericeous green with a vivid blue lateral border. Markings as in the typical 

 purpurea, a transverse and moderately reflexed median dash, not attaining the 

 sides, and a small sutural remnant of the apical lunule. Prothorax very 

 short and transverse, about twice as wide as long. Front sparsely punctate 

 and having erect blackish setse ; labial palpi black. Length 11.0-14.0 mm. ; 

 width 4.4-5.8 mm. 



California (Siskiyou Co.). 



This very beautiful form may be recognized at once by its 

 coloration, which appears to be quite constant, and also by its 

 very short and transverse prothorax. The anterior tarsi of the 

 male have the first three joints increasing in width, the third 

 quite strongly dilated and much less than twice as long as wide ; 

 in this structural character it differs noticeably from purpurea. 



C. plutonica. — Form nearly as in purpurea, but more elongate and 

 rather more convex ; body, legs and palpi intense black throughout ; labrum 

 pale, with a fine dark apical margin ; mandibles with the usual white external 

 dash. Head deeply concave between the eyes, the frontal convexity punctured 

 and more densely pubescent. Prothorax nearly as wide as the head, fully % 

 wider than long, nearly as in purpurea throughout. Elytra oblong, about 3^ 

 longer than wide, the intrahumeral impression at base very deep ; punctures 

 rather coarse but shallow, becoming sparse at base, with the subsutural series 

 of punctiform fovese distinct. Length 13.5 mm. ; width 5.2 mm. 



California (Placer Co.). 



The anterior tarsi of the male have the first three joints quite 

 strongly dilated and somewhat increasingly so from the base, the 

 third joint distinctly less than twice as long as wide. The elytra 

 are smooth along the lateral margins, but the only white macula- 

 tion is a small subsutural remnant of the apical lunule ; the punc-
