326 COLEOPTERA. 



Probably mixed in collections with Z. exclamationis, but 

 the claws at once differentiate it, and the striping differs. 



Calligrapha serpens nov. sp. 



Head green bronze, labrum yellow, antennae yellow with dark club, 

 thorax green bronze, coarsely punctate at the sides, sparselj' and finely 

 on the disk, deeply foveate on each side, elytra flavous, brown vittate 

 as follows : a narrow sutural vitta, forked at about the centre, forming 

 the vitta of the second interspace, the vitta of the fourth interspace is 

 entire from the base down over the convexity, where it turns outward 

 running nearly parallel to the lateral edge, and forming a long hook 

 reaching to the anterior fourth, at the bottom of the hook, near the 

 outside edge is attached a small supplemental hook, curved inward 

 parallel to the suture, a humeral vitta which is prolonged over the 

 elytra and occupies the centre of the space formed by the hook of the 

 fourth interval and is clubbed at the end, there is a small spot below 

 the humerus and a median one on the edge, body below and epi- 

 pleurae, blue green, feet rufous. Length 9 mm. 



Two examples, Guanajuato, Mexico. 



The sides punctures of the thorax are very coarse and 

 confluent, the edges evenly rounded, the scutel the color of 

 the thorax, the vittse of the elytra nowhere attain the base, 

 the long hook coupled with the abnormally long humeral 

 stripe easily identify this form. There are a few fine punc- 

 tures on the side and rear portions of the elytra, all the ely- 

 tral vittae are limited by punctures. 



There is a form of Calligrapha lunata Fabr. where the 

 usual short white inner discal stripe is reduced to an obso- 

 lete spot ; at the same time the sutural white stripe ends 

 abruptly about 2 mm. from the apex, otherwise it is strictly 

 typical, but unless the ordinary form is at hand it would 

 readily pass as a new species. 



One example, Mexico (in green). No. 429 among the un- 

 named Jacoby material, also one from Marion, Mass. 



Leptinotarsa siinilis nov. sp. 



Head and thorax viridi-aeneous bronzed, labrum and artennas flav- 

 ous, the latter a trifle darkened at the end, punctures moderate except 

 at the sides of the thorax where they are coarser and somewhat con- 

 fluent, also a deep fovea on each side, scutel aeneous, elytra pale flav- 

 ous with the following aeneous markings, a common wedge shaped 

 sutural vitta ending at the middle, a subsutural vitta nearly reaching
