DORYPHOEA. 255 



the sutural spot near the scutellum is placed quite close to the suture, and is almost 

 contiguous with the one on the other elytron: in B. 12-guttata this spot is much further 

 removed from the sutural margin. The thorax in the present species is less narrow ; 

 the sides, instead of being finely punctured like the disk, as in B. 12-guttata, are 

 strongly punctured. The metallic green colour of the upper surface in the latter 

 species is much more brilliant than in B. rogersi. Of the eight specimens obtained 

 by Mr. Rogers two show some slight variation in the size of the spots, which are 

 larger than in the others and nearly confluent. The abdomen in one specimen, 

 and part of the legs also, are obscure greenish aeneous ; but in all other respects the 

 specimens agree. The large size of the spots will at once distinguish B. rogersi from 

 other species similarly marked. The latter name must be substituted for the name on 

 the Plate.

This seems to be one of the most variable species of the genus, of which more than 

 sixty specimens were obtained by Herr Hoge, and, although not differing much 

 amongst themselves, are quite distinct from the description given by Stal as regards the 

 elytral pattern, yet evidently represent the same species. In the type the elytra have 

 the suture and four narrow longitudinal bands greenish aeneous, as well as the lateral 

 margin. In all the specimens from Cerro de Plumas the four elytral bands are inter- 

 rupted at the base and below the middle by transverse patches of the same colour as 

 the bands (generally greenish cupreous), in such a way that the latter are only visible 

 in the middle and at the apex, with the exception of the sutural band, which is entire. 

 The punctuation of the elytra is also much stronger than in the typical specimen from 

 M, Salle's collection ; and the thorax is equally variable, some specimens having a 

 shorter and wider thorax than others. Another variety before me shows no trace of 

 any bands on the elytra, which are of a uniform testaceous or fulvous. The most 

 constant characters seem to be the convex and greatly dilated form of the elytra 

 behind, the testaceous spot at the base of the head, and the light fulvous colour of the 

 tibiae and tarsi, as well as the very short mesosternal process. The figure represents a 

 normally coloured specimen from Mexico contained in my collection. 



As the specimens from Cerro de Plumas agree in general with the typical forms, 

 I prefer to consider them local varieties.
