248 PHYTOPHAGA. 



bands are narrower, the fulvous spaces dividing them consequently broader, and their 

 margins more regularly shaped. The thorax is distinctly more transverse, and has the 

 same silky opaque appearance and fine punctuation as B. subfastuosa, in which it 

 differs greatly from B. bella, which has a strongly punctured, nearly subrugose thorax. 

 B. blanda is similarly marked, but the bands of the elytra are differently shaped, espe- 

 cially the second one, which is of an almost triangular pointed form, while the apex is 

 but very narrowly marked with black.

In some specimens from Guatemala the entire base of the head is black, and the two 

 longitudinal bands of the thorax are very wide, almost occupying the entire sides. St&l 

 describes these bands as spots ; but in all the specimens before me, including some of 

 the typical ones from the collection of M. Salle, the thorax has two bands extending 

 from the base to the apex, near which two small spots are placed at each side, one 

 below the other. The elytra are greenish blue, with four oblong fulvous spots along 

 the lateral margin, and three others, larger and more transverse, placed parallel with 

 the suture. The mesosternal process in this species is very short. A Mexican 

 specimen is figured. 



15. Doryphora marginalis. (Tab. XV. fig. 15.) 



Black below . head with a triangular testaceous spot ; thorax flavous, with two longitudinal bands, connected 

 at the base, black; elytra irregularly geminately punctate-striate, greenish seneous, the lateral margin 

 (widened triangularly below the middle) and three subsutural spots flavous. 



Length 5-5| lines. 



Of same shape as D. mirabilis. Head very finely and closely punctured, black, a large triangular-shaped spot 

 between the eyes testaceous; labrum testaceous, spotted or margined with black; antennae black, the 

 basal joint testaceous below, terminal joints gradually widened, longer than broad. Thorax twice as broad 

 as long, the sides rounded and slightly widened before the middle, somewhat narrowed near the base, the 

 anterior angles not pointed but produced, surface irregularly covered with strong punctures remotely 

 placed ; at each side near the middle a broad longitudinal black band extends from base to apex, at which 

 latter place they are joined ; and this is also the case, to a less extent, near the anterior margin ; so that 

 these bands include an oval-shaped space of testaceous ; scutellum blackish, impunctate. Elytra regularly 

 convex, with about ten rows of double punctures irregularly placed, the punctuation becoming confused 

 and close near the apex; the ground-colour is a dark greenish aeneous, with the lateral margin narrowly 

 fulvous ; this colour is widened below the middle into a triangular-shaped spot ; three other spots are placed 

 parallel with the sutural margin : of these the first is situated below the base, near the scutellum, and is 

 of rounded shape ; the second, of transverse form, occupies the middle ; while the third is common to both 

 elytra, and ends in an elongate point near the apex. Underside and legs black. Mesosternal process 

 very short.
