of the body beneath also with yellow spots, forming a broad fascia 

 on the last ventral; head moderate, the eyes rather prominent, the 

 front without pale spots, coarsely, closely punctate, with a prominent 

 smooth callus along the median line centrally; antennae slender, pale 

 brown; prothorax two-thirds wider than long, but Httle narrower at 

 apex than at base, the former truncate, the latter bisinuate; sides 

 evenly, feebly arcuate; surface evenly convex, coarsely, not densely 

 punctate, without smooth spots or median line but with a small fovea 

 before the scutellum, the hypomera pale, the latter tint sometimes 

 spreading more or less broadly to the dorsal surface; elytra about two 

 and one-half times as long as wide, only just visibly wider than the 

 prothorax, very gradually rounded and narrowed posteriorly behind 

 the middle, the apices rather broadly sinuate and strongly bispiculose, 

 each with a yellow vitta from just beyond the middle of the base for 

 two-fifths or more, a transverse discal fascia at apical two-fifths and 

 another still more posterior, the apices also pale; stria; impressed, 

 punctulate, the intervals equal, moderately convex, becoming flat bas- 

 ally, finely, sparsely punctate; under surface finely, sparsely punctate, 

 more strongly and closely laterally. Length (c?, $) 17. 5-21.0 mm.; 

 width 5.4-6.7 mm. Pennsylvania, Indiana, Kentucky, Louisiana and 

 Kansas ruflpes Fabr. 



A — Similar to rufipes but much larger and stouter, the head more devel- 

 oped, with the front much more convex, the eyes fully as large but 

 not prominent, their contour following the general outline; scutellum 

 equally well developed, flat, rounded; elytra with the sides much 

 more rounding and converging posteriorly, the sinuate apices rela- 

 tively narrower though strongly bispiculose. Length 23.0 mm.; 

 width 7.4 mm. One specimen labeled "Cal." in Cab. Levette, but 

 probably in error virens n. subsp. 



Legs black and metallic bluish-green, the femora pale, vnth the upper side, 

 a lateral streak and the tip metallic black, the anterior pale only on 

 the under surface in basal two-thirds. Body rather less slender, shin- 

 ing, black to greenish-black, the under surface in great part pale; head 

 coarsely, densely punctate, with a few callous smooth spots, a large, 

 posteriorly cuneate median pale spot at apex and another at the lower 

 part of each eye, the latter not at all prominent ; antennae black with 

 feeble metallic lustre; prothorax as in rufipes, the sides broadly pale, 

 with a dark vitta on the hypomera; scutellum very much smaller; 

 elytra as in rufipes but less elongate and evidently wider than the pro- 

 thorax, very gradually and arcuately narrowed posteriorly to the apices, 

 which are briefly produced and each rather wide, deeply, obliquely 

 sinuate, the external angles strongly spiculate, the sutural much pro- 

 duced and acute, similarly striate, the intervals not distinctly punctate, 

 each elytron with a narrow reddish vitta from the humeral angles over 

 the callus to two-fifths from the base at outer third, a small discal spot 

 just behind the middle, another larger, more transverse and lateral at 

 apical fourth and a small longitudinal dash near the suture between 

 the last and the apices, the latter not pale; under surface completely
