AMERICAN COLEOPTERA. 121 



Var. Liaiirentii. Schaupp, I. c, p. 87. 



Occurs in Colorado. 



Dark brown, slightly bronzed, beneath blue green ; the humeral 

 lunule entire, sometimes connected with the middle band by a 

 narrow submarginal white line, middle band more prominent than 

 in typical longilahris, apical lunule entire and dilated anteriorly into 

 a conspicuously elongated spot. In a large series sent me by Mr. E. 

 J. Oslar from South Park, Colorado, the Schaupp description holds 

 good in nearly all the specimens, though the color is brighter than 

 his type and the submarginal band occasionally disappears. I have 

 specimens also from Golden, Colorado, both stations being in the 

 Rocky Mountains. Mr. Edw. D. Harris has a specimen from Silyer 

 Plume County, that is quite green. 



Var. Osiari n. var. — Form nearly as in longilahris. but more depressed; 

 above and beneath coppery bronze, except the abdomen which is brilliant jjreen, 

 and the white labrura and mandibles which are partly white ; or green through- 

 out, except the legs, tinged with bronze, and the white labruni. Elytral markings 

 a posthumeral dot, a middle band and a subapical dot; rarely there is a humeral 

 dot and still more rarely this is connected with the post humeral dot. The erect 

 haiisare less abundant beneath than in lonqihihris and entirely lacking above. 

 The elytral row of foveolse is also not to be found. 



Length 12-16 mm = 48-.64 inch. 



Habitat. — Snn Juan and San Miguel Mountains, Colorado, at an 

 elevation of 9500 to 12,000 feet. 



The bronze form of this variety was found along a sandy road 

 near the top of King Solomon Peak, Needle Mountains, San Juan 

 Range, Colorado, at an elevation of 9500 feet, July 29th to August 

 7th. The flight was heavy, slow and weak, and Mr. Oslar says this 

 species seems to prefer nmning to flying. The green form was found 

 on the southwest slope of Mt. Wilson of the San Miguel Range, 

 Colorado, at an elevation of 12,000 feet, July 18th to 27th. It 

 was found in a grassy valley of about half an acre, just at the 

 timber line, situated at the base of a perpendicular angle of the 

 mountain which afforded shelter from the terrific winds. 



I take pleasure in dedicating this variety to Mr. Ernest J. Oslar, 

 who first made it known to me, and whose labors have ^dded ma- 

 terially to our knowledge of Colorado Coleoptera. 



Var. vestalia n. var.— Form as in longilahris but mor^ convex; above 

 bright coppery bronze, shining; beneath metallic green, shining; or metallic 

 green above and beneath; elytra immaculate, granulate-punctate and with an
