ZYGOGKAMMA.— STILODES. 221 



testaceous, as well as the elytral epipleurse anteriorly, the posterior portion of which, as 

 well as the extreme lateral margin of the elytra, is piceous. There are four narrow 

 longitudinal bands on each elytron, the outer three of which unite at the apex ; the 

 space between the first and second band is slightly wider than those between the others. 

 The species seems to extend as far south as Brazil. 



28. Zygogramma magica. 



Calligrapha magica, Stal, Diagn. 1859, p. 322; Monogr. Chrys. Amer. p. 247. 



Hab. Mexico. 



According to the author's description, this species must be closely allied to Z. dulcis. 

 The type, with which I am not acquainted, is contained in the Berlin Museum. 



29. Zygogramma disrupta. 



Chrysomela disrupta, Rogers, Proc. Ac. Phil. 1856, p. 34, t, 1. f. 10; Suffir. Stett. ent. Zeit. 1858, 

 p. 271 2 ; Stal, Monogr. Chrys. Amer. p. 256 3 . 



Hab. Noeth Ameeica x 2 3 . — Mexico 3 . 



It is on the authority of Stal that Mexico is given as one of the countries inhabited 

 by the present species. I have never seen a specimen from that locality, and doubt 

 somewhat the correctness of Stal's quotation. 



STILODES. 



Stilodes, Chevrolat in d'Orbigny's Diet. Hist. Nat. iii. 1843, p. 656; Baly, Ann. & Mag. Nat 



Hist. ser. 3, iv. p. 58. 

 Deuterocampta, Erichs. Arch. f. Nat. 1847, p. 157. 



Considerable confusion seems to prevail in regard to the genera Stilodes and Deute- 

 rocampta, which I do not see the necessity to separate, it being in fact impossible 

 to draw a strict line between the numerous species which have been described as 

 belonging to either genus by Stal, Baly, and other authors. The numerous types and 

 specimens which I have before me admit of no strict separation ; and I think it best to 

 unite those from Central America, at least, under the older generic name of Stilodes. 

 Chapuis also remarks that Deuterocampta is but feebly characterized, but says that the 

 strong punctuation of the metasternal epipleurse separates it from Stilodes. This is not 

 at all the case with many species, S. annuligera, Erichs., for example, showing very 

 strongly punctured epipleurae, as well as many species at present placed in the same 

 genus. Deuterocampta, on the other hand, has all the other structural characters to be 

 found in Stilodes, most of which, however, will be found to vary to a smaller or greater 

 degree, but, in my opinion, not sufficiently to separate those species hitherto placed in 

 the two genera in question.
