264 GEO. H. HORN, M. I). 



Specimens do, however, occur with a hhiiish or slightly cupreous 

 surface. Two sped mens are before me froni Colorado with the tho- 

 rax not more coarsely punctate than in denUculata, but these are 

 considered merely variations. In the majority of specimens the 

 scutellar stria is sliglitly irregular. The posterior thighs are elon- 

 gate oval, nearly twice as long as broad. 



Occurs in Kansas, Colorado, Montana, Arizona and California 

 (Owen's Valley). 



15. C opuleiita n. sp. — Oval, moderately convex, surface not alutaceous, 

 briglit j^olrlen or brassy bronze. Antennfe riifotestaceous at base, g-radually 

 darker to tip. Head slijibtly alutaceous and feebly wrinkled. Thorax twice as 

 wide as long, narrowed at apex, sides regularly arcuate, basal marginal line en- 

 tire and well marked, the surface coarsely, deeply and closely punctate. Elytra 

 a little wider at base than the thorax, humeri rounded, umbone smooth, not 

 prominent, strise feebly impressed, the punctures very coarse and deep, closely 

 placed, the intervals slightly convex, more so at the sides, not wider than the 

 striae, distinctly punctulate. Hody beneath distinctly seneous. Prosternum 

 closely punctate, side pieces smooth. Abdomen sparsely punctate, last three 

 .segments smooth at middle. Femora piceous, the tibise and tarsi testaceous. 

 Length .08— .10 inch. ; 2 — 2 5 mm. 



Closely resembles subvirldls, but may be known by the color, the 

 distinctly wrinkled head, the coarser elytral punctures with narrower 

 intervals and by the very pale tibite and tarsi. The scutellar stria 

 is always regular. The posterior thighs are strongly incrassate, the 

 width being nearly three-fourths the length. 



Occurs in California (Owen's Valley ) and western Nevada, also 

 New Mexico (Ulke). 



16. C «»besillsi Lee — Oval, moderately robust, black bronzed, rather shin- 

 ing. Antennse reddish brown at base, piceous externally. Head extremely 

 finely alutaceous, impuuctate. Thorax nearly twice as wide at base as long, ar 

 cuately narrowed to apex, surface extremely finely alutaceous. not visibly punc- 

 tate, the basal marginal line fine and entire, the punctures at the side relatively 

 coarse and distant. Elytra wider at base than the thorax, humeri rounded, um- 

 bone distinct, disc convex, shining, not alutaceous, strise finely impressed, the 

 punctures rel.itively coarse, deep and close, the intervals wider than the stripe, 

 very slightly convex with a row of distant, intersti'ial punctures. Body beneath 

 black, shining. Abdomen very indistinctly punctate. Femora piceous, tibiae 

 and tarsi pale. Length .05 inch. ; 1.25 mm. 



This species is one of the smallest in our fauna, and is especially 

 characterized by the impuuctate thorax and almost truly black color. 

 Occurs at Enterprize and Lake Ashby, Florida.
