AMERICAN OOLEOPTERA. 133 



Black above and beneath, elytra with short, oblique, slightly 

 sinuate middle band, not attaining the margin, and apical dot; some- 

 times with ante-apical dot also, and more rarely with a faint humeral 

 dot The usual brush of hair is very conspicuous and the thorax 

 above is hairy at the sides; beneath, the palpi, the flanks of the 

 thorax and the legs are very hairy, and there are some hairs on the 

 abdomen. 



Occurs in 111.; Neb.; Kan.; Colo.; Wis.; Dak.; Wyoming. 



Mr. Oslar writes that this variety is abundant in dry sandy spots 

 on the prairie around Denver, and occurs also along the damp sandy 

 banks of mountain streams throughout the State.

Habltat.-Flsicer Co., Cal. ; Alpine, Oregon, June 27th. 

 Black above and beneath, elytra immaculate except for an apical 

 dot present in some specimens. The presence of a row of faint 

 foveol^e along the suture is a character which assists in separating 

 this variety. 



Var. lanta Casey, I. c, p. 296. 



This variety is known to me by a single specimen and the author's 



description, and I am unable to place it accurately without a larger 



series It appears, however, to run very close to the Californian forms 



of graminea. I copy here the original description : " Similar in form 



" to purpurea, but 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 



" setaj ; labial palpi black." 



Occurs in Siskiyou Co., Cal. 



Mr Harris has specimens of graminea from Gold Hill, Oregon, 

 which apparently correspond with the description of lauta Casey, 

 and which were taken with specimens of typical cjrammea. The 

 name may in any event be retained for those Pacific forms which are 

 all green and feebly marked, as Schaupp's description really covers 

 the Kansas and Colorado form only.
