598 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [NoV. 16, 



impressed row of punctures parallel with the extreme lateral margin. 

 Scutellum elongate. Elytra wider than the thorax, finely impressed 

 with double rows of punctures, which are nearly obsolete near the 

 apex, flavous or testaceous, with a spot below the base, the anterior 

 half of the suture and tliree broad deeply erose bands greenish 

 seneous ; the first of these bands is placed before the second, 

 behind the middle, while the third occupies nearly the apex, 

 none of them extending to the lateral margin ; they all, however, 

 extend to the suture, and consist each of three or four longitu- 

 dinal patches connected together. 



This species is closely allied to D. sahini, Baly, but differs in the 

 finer punctuation of the elytra, and in the markings of the latter, 

 which in the present S|)ecies do not extend to the lateral margins, 

 and are also wider, the space between them being much narrower 

 than in D. salvini. 



55. DORYPHORA SEXGTJTTATA, Sp. HOV. 



Ovate, convex. Dark fulvous ; elytra regularly punctate-striate, 

 each elytron with six flavous spots, viz. four placed longitudinally 

 near the sutural, two near the lateral margin. 



Length 4| lines. 



Head finely and rather closely punctured, labrum testaceous. 

 Antennae black, the basal joint entirely and the second one below 

 testaceous, terminal joints slightly longer than broad. Thorax a 

 little widened in the middle, its sides very moderately rounded from 

 base to the apex, anterior angles not produced but acute; surface 

 nearly impunctate, sides with a few distinct punctures, dark fulvous, 

 shilling. Scutellum smooth. Elytra very convex and regularly 

 rounded, each elytron with ten rows of very distinct punctures, 

 which mostly unite at their apex and are interrupted by the flavous 

 spots; four of the latter run parallel with the sutural margin and are 

 of a round shape ; the other two are larger, more elongate, and placed, 

 one at the shoulder, the other below the middle near the lateral 

 margin. Underside and legs a little hghter fulvous. 



From D. \2-guttata, Fabr., this species is principally distinguished 

 by the single punctured striae of the elytra, which are geminate in 

 the former species : the shape and position of the spots are also 

 slightly diff'erent. 



56. DoRYPHORA MARGINICOLLIS, Sp. nOV. 



Oblong-ovate, convex, widened behind. Black ; above bronze- 

 coloured, closely punctured ; an elongate spot at the head, the lateral 

 margins of the thorax and of the elytra flavous testaceous. 



Length 5 lines. 



Head rather closely covered with larger and smaller punctures, 

 with a longitudinal central testaceous spot. Thorax narrow, its an- 

 terior margin straight, the posterior one slightly rounded, sides 

 straight near the base, rounded from the middle to the apex, an- 

 terior angles acute but not produced ; surface punctured like the 

 head, more closely near the sides than on the disk ; brownish aeneous.
