14. Zygogramma quinquevirgata. (Tab. xii. fig. 21.)

Hdb. Mexico 1 . 



The type, formerly in the collection of Deyrolle, and which is figured, is of a dark blue 

 colour ; the elytra are testaceous, and have, besides the sutural band, two others of very 

 regular shape and joined at their apex, placed on the disk of each elytron; of these 

 bands the inner one is the widest, both are crowded with deeply impressed punctures ; 

 the lateral margin, as well as the epipleuree, is blue also, the former having another 

 narrow band running close to its edge from the middle to the apex. I have seen no 

 other specimen but the type, now in the collection of Mr. Baly. 



15. Zygogramma aeneo-vittata. (Tab. XII. fig. 3.)

Of this species I have Stal's type, formerly in the collection of Deyrolle, for exami- 

 nation ; it agrees with a number of specimens from the above localities ; the elytra, 

 however, can scarcely be called three-banded, as described by Stal. In all the specimens, 

 as well as in the type, there is only a narrow band placed near the suture and connected 

 at its apex with a broad band near the lateral margin ; this latter band is often notched 

 at the middle, or interrupted partly by the ground-colour, as described by Stal ; but in 

 many specimens this is not the case, and the band is entire; none of these bands 

 extend quite to the base of the elytra. Like many other species, the colour of the 

 body and thorax varies from dark fulvous to greenish black. G. Iwta, Sturm, refers to 

 another species, and is not synonymic with the present one, as stated in Gemminger's 

 catalogue.

Allied to Z. malvce, but at once to be distinguished by the testaceous thorax, which 

 has a large triangular greenish-black or obscure dark ferruginous spot occupying the 

 entire base and extending in a point to the anterior margin. Suffrian and Stal have 

 described a variety, in which the first of the two longitudinal bands, which are joined 

 posteriorly, is broken up into two or three spots, under the name of Z. stolata. The 

 species often varies in this respect: the above-mentioned vitta is either entire or inter-
