interrupted at the humei'i in this species, while in crlbrlfrons and 

 piiir/iils, with which it is most closely related, the outline is con- 

 tinuous. 



Occurs in Arizona, probably Fort Thomas ; represented by one 

 specimen only. 



11. (j. opaeula Lee. — Oval slightly oblong, moderately robust, dark green- 

 ish bronze, very feebly shining. Anteunse with basal joints brownish, the outer 

 piceous. Head very opaque, sparsely, indistinctly punctate. Thorax about one- 

 half wider than long, distinctly narrowed in front, sides regularly arcuate, 

 widest at base, basal marginal line indistinct, but with punctures coarser than 

 the discal, forming an irregular series, discal punctures rather fine, feebly im- 

 pressed, moderately closely placed, the surface opaque. Elytra a little wider at 

 base than the thorax, humeri distinct, umbone smooth, moderately prominent, 

 strise scarcely impressed, composed of moderately coarse, closely placed sub- 

 transverse punctures, the intervals scarcely wider, not convex, more shining 

 than the thorax, indistinctly pnnctulate. Body beneath piceous, slightly bronzed. 

 Prosternum coarsely punctate, side pieces smooth. Abdomen subopaque, coarsely, 

 sparsely punctate at the sides, smoother at middle. Femora piceous, tibiffi and 

 tarsi brown. Length .06 inch. ; 1.5 mm. 



Although quite different in appearance from minuta, it is difficult 

 to separate it by descrij)tion. The characters given in the table, 

 sup})leniented by the desci'iption, will enable separation to be made. 



A specimen which I am at present unwilling to separate from this 

 species, in Mr. Schwarz's collection from Alamosa, Colorado, has 

 much more shining elytra and the basal punctures of the thorax less 

 distinct. 



Occurs in California (Gilroy) and Colorado? 



12. ('. inillllta Mels. — Oval, facies very robust, piceous, surface distinctly 

 bronzed, shining. Antennse with four basal joints brownish testaceous, the outer 

 piceous. Head distinctly alutaceous, sparsely, indistinctly punctate. Thorax 

 twice as wide as long, evident at middle, scarcely narrower at apex than base, 

 sides arcuate, disc very faintly alutaceous, the punctuation sparse and fine, basal 

 row of punctures distinct and a little more in front of basal margin than usual, 

 and coarser than those of the disc. Elytra distinctly wider at base than the 

 thorax, humeri broadly rounded, umbone smooth, not prominent, .stride faintly 

 impressed, the punctures moderate in size, rather closely placed, a little trans- 

 verse, intervals feebly convex, very slightly alutaceous, not visibly pnnctulate. 

 wider than the strise. Body beneath piceous black, faintly bronzed. Prosternum 

 closely punctate, the side pieces smooth. Abdomen spar.sely punctate. Legs 

 piceous, the tibise and tarsi sometimes paler. Length .08 inch. ; 2 mm. 



This species escaped the notice of LeConte and Crotch. Fortu- 

 nately, the type in the Museum at Cambridge is in good condition, 

 and the above description has been taken from it in comparison with 

 other specimens.
