It is with some degree of doubt that I give the insect described 

 above Eiichson's name ; his description is short, and agi'ees equally 

 well with four or five closely allied species ; the locality, however, 

 of the present insect agrees with that of his insect. 



5. Cephaloleia Erichsonii, n. sp. 

 C. elongata, subdepressa, pallide fulva, nitida ; antennis (basi ex- 

 cepto) nigris ; thorace subquadrato, basi angustato, lateribus 

 leniter rotundatis ; elytris teniaiter punctato-striatis ; pygidio ob- 

 tuse tnmcato. 



Mas. Antennarum articulis quinque basalibus subcompressis, 

 articulis secundo et tertio fere sequalibus, subtrigonis ; abdominis 

 segmento auali truncato, leniter sinuate. 



Foem. Antennarum articulo tertio obconico, secundo longiori ; 

 abdominis segmento anaH late sed leniter emarginato. 

 Long. 4 lin. 



C. elongate, subdepressed above, pale shining fulvous ; antennae 

 black, one or two basal joints fulvous ; male with the first foiu- 

 or five joints subcompressed ; basal (Tab. III. fig. 5 a) clavate, 

 incrassate, almost twice as long as the second ; second and third 

 nearly equal, subtiigonate ; third joint in the female longer than 

 the second. Thorax subquadi'ate ; sides with a broad reflexed 

 border, shghtly rounded, somewhat dilated and more distinctly 

 rounded in front (causing the thorax to appear narrowed behind) ; 

 produced beyond the apical margin, the latter shghtly convex, an- 

 terior angles obtuse ; siirface smooth, slightly convex transversely, 

 very finely and sparingly punctured. Elytra rather broader than 

 the thorax, scarcely four times its length ; apex obtusely rounded, 

 above moderately convex, flattened along the back ; sides deflexed 

 and excavated below the shoulders ; just within the humeral 

 callus is an indistinct longitudinal fiu-row ; each elytron with 

 eleven rows of very fine punctures, the fii'st abbreviated. Pygi-

This species, although very closely alHed to Ceph. coralUna, may 

 be at once separated by the shape and finer punctation of its thorax,
