Near Crepidodera, but separated by the different form of the an- 

 tennae and the irregularly punctured elytra. 



Prasona viridis. 



P. elongata, subparallela, pallide viridis, subnitida ; antennis obscurioribus, 

 piceo tinctis ; femoribus anterioribus dorso lineatis nigro ; elytris crebre 

 punctatis, linea suturali male definita, vitta brevi leniter curvata intra 

 bumeros posita, niaeida prope medium disci vittaque submarginali a 

 callo bumerali ad paidlo pone medium extensa piceis. — Long. 3f lin. 

 Var. A. Elytris immaculatis. 



Hob. Mexico. 



Elongate, moderately convex. Face trigonate, elevated between tbe 

 eyes, upper portion of the raised space impressed by a longitudinal 

 fovea; vertex finely but remotely punctured. Thorax nearly twice 

 as broad as long, sides subparallel, sinuate at the base, slightly dilated 

 and rounded before the middle; above closely punctured, a narrow 

 longitudinal space down the middle impunctate ; disk impressed on 

 either side with shallow irregular excavations, base transversely sulcate, 

 side border reflexed. Elytra broader than the thoi*ax, sides subparallel, 

 slightly ovate, upper surface closely punctured ; on the disk of each 

 elytron are seen (with difficulty in some specimens) five or six obso- 

 letely elevated vittse ; one, rather more distinct, extends from the 

 humeral callus down the side a short distance within the lateral border, 

 the space between this latter and the vitta concave.

Chrysomela cingulata, ante, p. 97. This insect was described 

 some years since by the Rev. F. W. Hope, under the name of 

 Chrysomela Vishnu, in his paper on Nepaulese Insects, published in 

 Gray's ' Zoological Miscellany,' p. 30 ; my name must therefore fall. 

 I unfortunately overlooked the type in the British Museum collection 

 when I wrote my paper ; and Hope's description is so short and im-
