 Weber] decora Fabr. 



Elytra rounded at tip, the sutural angles acute and more or less prominent. 2 



2 — Coloration nearly as in the preceding, bright and metallic, with the elytral 

 suture and side margins cupreous. Form shorter and relatively stouter 

 than in decora, generally paler and more uniform brassy-green, the elytra 

 sometimes broadly suffused with darker, though usually greenish-blue; 

 under surface bright cupreous; head smaller; similarly sculptured 

 though more coarsely in the female, where there are some irregular 

 smooth spots; prothorax similar but more rounded at the sides and 

 more longitudinally convex, sometimes with vestiges of an impressed 

 and more punctate median line, the punctures still coarser, not dense 

 and more evenly disposed; elytra only two-thirds or more longer than 

 wide, slightly wider than the prothorax, almost similarly formed, the 

 serial perforations coarser, the punctures similar though relatively 

 smaller and more apt to be distributed in a single line on some of the 

 intervals, owing to the coarser serial punctures; under surface as in 

 decora, the relative hairiness of these parts and of the head of the male 

 and female similar. Length 1 2.0-13.6 mm.; width 4.5-5.5 mm. 

 New Jersey and New York ultramarina Say 



Coloration nearly uniform and more sombre, the elytra without cupreous 

 suture or margins 3 



3 — Form oblong-oval, moderately convex, dull or feebly shining, obscure 

 cupreous-brown, the anterior parts brighter but with the more elevated 

 portions black (9), or with the elytra obscure green (d^); under sur- 

 face bright cupreous throughout, with greenish reflections; head very 

 densely compresso-punctate, more coarsely so and less hairy in the 

 female, the median line carinate centrally; eyes moderate, not very 

 prominent; prothorax trapezoidal with feebly arcuate sides, three- 

 fifths wider than long, with a rather pronounced groove along the 

 apical margin laterally; punctures strong, sparse medially, where there 

 is a nearly entire impunctate line in the female but not in the single 

 male at hand, dense and confluent near the sides; scutellum oblong, 

 depressed on the disk, with a median elevation; elytra three-fourths or 

 more longer than wide, evidently wider than the prothorax, the oblique 

 sides in apical third almost straight (c?), to decidedly arcuate through- 

 out (9), the surface even, except a sublateral ridge which is obsolete 

 basally and feeble ( d^), or very pronounced ( 9 ), the serial perforations 

 rather coarse, more or less elongate, the cribration dense, becoming 

 very crowded laterally; under surface finely punctate, sparsely so (9), 

 or more densely and more pubescent (d^). Length 16. 0-18.0 mm.; 

 width 5.8-7.0 mm. Alabama (Grand Bay) cribripennis n. sp 



Form more elongate and rather more convex, dark and uniform bronze- 

 brown above, more cuprascent anteriorly, bright cupreous throughout 

 beneath; head more densely and uniformly compresso-punctate, the 

 eyes decidedly smaller and less convex, not at all j)rominent; prothorax
