AMERICAN COLEOrTERA. 131 



A. phalerioides, n. sp. — Elongate oval, pale yellowish testaceous, shining. 

 Head nearly smooth, finely and very sparsely punctulate; ciypeus very feebly 

 emarginate and broadly rounded on each side. Thorax moderately convex, 

 sparsely punctured, sides moderatelv rounded, base not margined at middle. 

 Elytra elongate oval, yellowish testaceous, slightly clouded with fuscous, feebly 

 striate, strife finely punctured ; interspaces moderately convex, very sparsely 

 punctulate. Body beneath pale yellowish testaceous, hind tibite slender. An- 

 terior tibife nearly truucate at apex, teeth obtuse, the upper obsolete, inner edge 

 slightly sinuous. Length .24 inch; 6 mm. 



A curiou.s species resembling consentaneus, in appearance, but may 

 be easily known by its stouter hind tibia), and by the peculiar confor- 

 mation of the anterior. 



The specimens in our cabinets are from the Middle States, probably 

 from near the sea coast. 



Group >I contains several species with the elytra distinctly pubes- 

 cent over the entire surface and more opaque than in the preceding 

 group. 



The species in our fauna are as follows : 



Elytra luteous with fuscous cloud ; thorax at base margined. 



Anterior tibia;, % , strongly sinuate within, spur hooked Walshii. 



Anterior tibia;, % , normal, spur broad, truncate femoralis. 



Elytra reddish-yellow; thorax not margined at base. 



First joint of hind tarsus equalling the last four together rubripennis. 



A. femoralis, Say, Journ. Acad, iii, 1823, p. 215. — Oblong, head and thorax 

 black, shining, elytra luteous with broad fuscous space, sub-opaque and pubes- 

 cent. Head sparsely punctured, margin very feebly reflexed ; ciypeus feebly 

 emarginate and rounded on each side.' Thorax moderately convex, very 

 sparsely punctured, at the sides luteous, sides moderately rounded, base dis- 

 tinctly margined. Elytra luteous with broad fuscous space varying in extent, 

 striae moderately deep, serrately punctured, interspaces convex usually coarsely 

 punctulate especially near the strife. Body beneath piceous, femora pale lute- 

 ous, tibia; darker. Length .22 — .26 inch ; 5.5 — 0.5 mm. 



Male. — Elytra more coarsely punctulate, spur of anterior tibia broad, thick 

 and truncate at tip. 



Female. — Elytra more sparsely punctulate, spur of anterior tibia slender and 

 acute at tip. 



This species resembles consputus, of Europe, but may be known by 

 the distinct marginal line at base of thorax as well as by the sexual 

 character of the male. The margin of head is much less distinctly re- 

 flexed than in the following species and it is this difference alone that 

 must be relied on to distinguish the female of Wa/shii ivoxn femoralis. 

 The tibia) are always much darker in color in the latter species than 

 the femora, while in the former the legs arc of one color. This can 

 not however be relied upon to separate them by being a character of 

 comparative, little value from the tendency to variation.
