punctures, the punctures between the oblique abbreviated stria and the 

 suture are confused. 



CHRYSOMELA Linn. 

 C. continua, ovalis, supra ferruginea, thorace ad latera grosse punctata, niar- 

 gine apicali lateribusque pallidis; elytris pallidis, vitta suturali antice diver- 

 genle, alterisque utiinque duabus latis postice connexis epipleurisque ferrugi- 

 neia; subtns obscure ferruginea, piceo variegata; antennis articulis ultimis 

 (juinque piceis. Long. 6'5 — 7 mm. 



South of Raton Mountain, Dr. Lewis. Of the same size, form and 

 sculpture as C con/'iaicta, and differing only by the absence of sub- 

 marginal elytral spots and by the vittae being broader, not sinuous, and 

 not interrupted. The stripes, as usual are limited by well marked 

 series of punctures ; the sutural stripe is nearly smooth, the two dorsal 

 ones are strongly punctured, the pale ground of the elytra is very 

 feebly and sparsely punctured, and there are three rows of punctures 

 between the outer stripe and the margin ; the inner two of these are 

 abbreviated. 



I have seen specimens of this species from Arizona. 



C. conjuncta Rogers, Proc. Ac. Nat. Sc, PhiL 1856, 34, tab. 1, fig. 9. 

 A large series of specimens collected on the Smoky Hill and Ark- 

 ansas rivers shows that C. stulata Suffr., and C. pallida Bland, are 

 merely varieties of this species. In the first named, the dorsal vittj4e 

 of the elytra are entire, and united behind ; in the second the inner 

 vitta is interrupted in front of the middle ; in another variety the in- 

 terruption is behind the middle, and the outer vitta is more sinuous 

 than usual ; in C. pallida the inner vitta is interrupted both before 

 and behind the middle, and the outer one is still more sinuous, with a 

 tendency at the outer angle of the sinuosity to the formation of a se- 

 parate spot. 



LUPEBTIS Geoffr. 

 L. luteicollis, niger, capite nitido paree subtiliter punctato, thorace flavo, 

 dense punctulato, longitudine duplo latiore, apice fere truncate, lateribus cum 

 basi rotundatis, angulis anticis subrectis, posticis obtusis rotundatis; elytris dense 

 punetulatis, nigro-cj'aneis, hie inde obsoletissime striatis ; antennis articulo .3io 

 praecedente sesqui longiore ; 4to illis conjunetis aequali. Loug. 4'5 mm. 



South of Raton Mountain, and at Fort Union. A very pretty spe- 

 cies, more allied to L. fhorucicus than to any other in my collection. 

 For a synopsis of our species vide Proc. Ac. A^af. Sc, Phiala., I860, 

 208. 



L. varicornis, pallidus, subtus infuscatus, elongato-ovalis, supra baud dense 

 punctulatus, thorace latitudine breviore, angulis posticis obtusis rotundatis; 

 elytris thorace latioribus, paulo fortius punetulatis; antennis corpore paulo 

 brevioribus, articulis 4 — -11 apice infuscatis. Long. 3 mm.
