208 PROCEEDINGS OP THE ACADEMY OP 



I found this species quite abundant near the Arkansas Rivet, below Bent's 

 Fort. Say states that it lives on Amorpha fruticosa. It differs from the 

 next by the head and thorax being entirely yellow, with the impression of the 

 latter tolerably deep, as in Phyllobrotica decorata. 



2. Ph. dor sal i s Dej., Cat. 406. Galleruca dors. Oliv., Ent. vi. 646, (No. 

 93, 52,) pi. 4, f. 54. 



Two specimens from Kansas ; is also found in the Southern States. Of the 

 eanie size, form and sculpture as the preceding, but the discoidal impression 

 of the thorax is very faint, and it is marked with two black vittse, which 

 sometimes unite along the anterior margin, thus causing the anterior part of 

 the thorax to become blackish ; the tibiae and tarsi are entirely black. 



3. Ph. gentilis, elongatus, nitidus flavo-testaceus, supra laevis, thorace 

 quadrato, dorso vage transversim impresso, vittis duabus latis nigris ornato, 

 elytris nigris, sutura margine laterali apicalique anguste navis : antennis 

 fuscis, articulis 4 et 5 testaceis. Long. "15. 



Three specimens ; Georgia. A very pretty little species, easily distinguished 

 by the characters given above. The discoidal impression of the thorax is 

 faint ; the under surface of the body is yellow, with the last ventral segment 

 of the abdomen fuscous. The legs are entirely yellow. The sexual characters 

 are as in the two preceding species. 



LUPERUS Geoffr. 



The species of this genus as now restricted will be readily recognised by 

 the e'ongate form, the quadrate thorax, without discoidal impression, and 

 the epipleurae moderately wide at base, not extending to the tip of the elytra. 

 The body is glabrous, shining and nearly smooth above. The antennae are 

 11-jointed in both sexes ; the 2d joint is shorter than the 3d, but the latter is 

 not equal to the 4th. The maxillary palpi are rather slender, with the last 

 joint as long as the preceding, gradually narrowed to the tip, which is 

 rounded. The thorax is truncate at the apex, slightly rounded on the sides, 

 nearly truncate at base, with the hind angles acute and laterally prominent. 

 The front coxae are conical and contiguous ; the legs are slender, the tibiae not 

 Bulcate externally, and the ungues have a broad acute basal dilatation. 



In the males the antennae are a little longer than in the females, and the 

 5th ventral segment is broadly impressed and truncate at the tip. 



Our species may be distinguished as follows : 



A. Prothorax yellow : 



Yellow, elytra black, pectus and abdomen fuscous 1. thoracicus. 



Yellow, occiput, base of elytra and transverse spot behind 



the middle fuscous, pectus black 2. fibulatus. 



Yellow, elytra with suture and submarginal vitta black.. 3. bivittatus. 

 Blue shining, prothorax yellow, post pectus black 4. flavicollis. 



B. Body uniform in color. 



*Hind angles of prothorax not prominent, but acute : 



Prothorax sparsely punctulate, hind angles not prominent:
