196 long's second expedition. 



dull rufous ; antennae pale, dusky at base and tip ; thorax punc- 

 tured ; punctures rather large and profound, but not very dense ; 

 no impressed line; posterior angles with a minute abrupt excurva- 

 ture acute ; elytra punctured like the thorax, with a longitudinal 

 white vitta on the middle of each, commencing at the middle of 

 the base and extending rectilinearly, with a slight degree of at- 

 tenuation to near the tip, and occupying about the sixth part of 

 the surface ; feet pale, posterior thighs dusky towards the tip. 



Length three-twentieths of an inch. 



This species resembles A. striolata Schoenh., (which seems to 

 be the Crioceris vittata and Galleruca elongata of Fabr., and 

 Mr. J. F. Melsheimer quotes also as synonymous, the A. flexuo&a 

 Panzer,) but it is larger, of a more elongated form, and the vitta 

 of the elytra is not flexuous as in that common and profusely 

 named insect. I have not met with it in the Atlantic States. 



EUMOLPUS Kugell. Latr. 



1. E. elavidus. — Pale yellowish; elytra striate with double 

 series of punctures. 



Inhabits United States. 



Body densely punctured ; punctures rather large and profound; 

 head with two slightly elevated tubercles between the antennae ; 

 thorax tinged with rufous ; elytra with elevated lines, of which 

 the inner one curves round at base and descends a short distance 

 to unite with the sutural line ; interstitial spaces, excepting the 

 subsutural one and the two exterior ones, with double series of 

 rather [296] large profound punctures ; exterior edge blackish- 

 brown ; venter dusky. 



Length nearly one-fifth of an inch. 



Var. a. interstitial spaces of the elytra black ; beneath except- 

 ing the feet, black. 



This insect is common in Pennsylvania; the variety was ob- 

 tained on St. Peter's river, and might readily be mistaken for a 

 distinct species. 



[Belongs to Colaspis. — Lec] 



2. E. cochlearius. — Body black; base of the antennae, tibia 

 and elytra testaceous. 



Inhabits North-west Territory. 



Body short, robust ; head punctured, hairy ; an impressed line
