 Length 17-18 mm.^.68-.72 inch. 



Habitat. — Kau. ; Tex. ; Col. ; Neb. 



Red cupreous, margins shining, beneath metallic blue or green ; 

 head granulate rugose, hairy in front and beneath the eyes; thorax 

 broader than long, granulate, very hairy on the flanks ; elytra feebly 

 granulate-punctate, the punctures rather distant and the surface 

 between them very minutely punctulate ; markings consist of hum- 

 eral lunule, middle band obtusely bent but only slightly deflexed, 

 and apical lunule, all narrowly connected along the margin ; inter- 

 ocular strise deep and numerous ; beneath, the palpi, trochanters, 

 femora and sides of thorax and abdomen are very hairy ; labrum 

 strongly three toothed. 



This species inhabits a comparatively limited district and presents 

 very little variation in its markiug.s. Mr. Knaus says its favorite 

 places are in the short grass and weeds near the edges of sand dunes 

 and " blow-outs." It occurs from the end of May to July and again 

 in the fall.

Very similar to the preceding except in color, markings and geo- 

 graphical distribution. The markings are subject to great variation 

 as well as color. The constant difference is in the direction of the 

 middle band which is always more deflexed than in formosa. 



Dull red cupreous, green beneath ; or brown bronze, dull green 

 beneath ; or green bronze with cupreous reflection, dull green 

 beneath ; markings consist of humeral lunule, middle band strongly 

 deflexed (its extremity almost reaching the suture), apical lunule, all 

 connected by a narrow marginal band ; rarely there is a narrow 

 break in the marginal line behind the humeral and before the apical 

 lunule. Always less shining than formosa. Otherwise as in the 

 preceding. 



This species occurs abundantly in the Pine Barrens of New Jersey, 

 frequenting the white sandy roads through the woods, preferring the 

 more open spots. We find it there early in spring and its season
