sculpture, smaller and more transverse prothorax, and in the form 

 and position of the elytral markings, the transverse reflexed line 

 being finer, less reflexed and more posterior in position. 



C echo n. sp. — Eather narrow and convex, dark coppery brown, the punc- 

 tures of the elytra blue or greenish-blue ; under surface and legs metallic 

 bluish-green. Head moderate in size, deeply and finely strigato-rugose and 

 bald ; labrum imperfectly tridentate, the lateral teeth very short and rounded ; 

 labial palpi pale, the third joint black ; antennae slender. Prothorax not quite 

 as wid&as the bead, % to % wider than long, almost cylindric and only slightly 

 narrowed at base, the white pubescence abundant but subdecumbent on the 

 flanks ; impressions deep ; surface minutely but deeply rugose. Elytra dis- 

 tinctly wider toward apex, '% longer than wide, coarsely, rather closely and 

 almost uniformly punctured ; intrahumeral impression narrow, rather deep 

 and with coarser punctures ; white maculations broad, consisting of a complete 

 humeral lunule, which intrudes but little upon the disk behind, a transverse 

 and strongly reflexed line, attaining the margin at the middle and almost at- 

 taining the suture behind apical third, and a complete apical lunule. Length 

 10.8-12.0 mm.; width 3.9-4.7 mm. 



Utah (Great Salt Lake). 



This species also belongs to the senilis group, and differs from 

 that species in its narrower form, more cylindrical prothorax, 

 more metallic coloring, form of the elytral markings and in the 

 much less dilated basal joints of the anterior male tarsi. The 

 male is much less stout than the female. 



C. inquisitor n. sp. — Eather stout, moderately convex, feebly shining, 

 coppery-brown in color; elytral markings as in sperata, except the median re- 

 flexed band which is more even, less angularly reflexed and situated at a 

 greater distance from the end of the humeral lunule, the latter relatively much 

 shorter and less oblique; under surface metallic greenish, the legs coppery 

 green. Head broad with the eyes very prominent, feebly strigato-rugose, 

 finely and sparsely punctured anteriorly, the pubescence white, sparse, decum- 

 bent and consisting of very short and stout hairs; labrum, mandibles, palpi 

 and antennae nearly as in sperata. Prothorax nearly ^^ wider than long, par- 

 allel, constricted at apex and more feebly near the base, the sides between the 

 constriction and the base notably protuberant; impressions rather feeble; sur- 

 face dull but almost smooth, minutely and feebly creased. Elytra oblong, V2 

 longer than wide; sides parallel and almost evenly arcuate; apex oblique, the 

 subapical angles prominent but obtusely rounded ; surface evenly convex, the 

 intrahumeral impression feeble, with the feveolse small; punctures moderately 

 coarse, finer toward the suture, nearly as in sperata and having a similar blue 

 color. Under surface densely pubescent toward the sides, the legs very slender. 

 Length 14.0 mm. ; width 5.2 mm. 



Texas (Austin). 



The present species is allied closely to sperata but is stouter,
