r»96 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [NoV. 16, 



Length 4^-5 lines. 



Head with some fine punctures and irregular impressions near the 

 eyes ; anterior margin of labrum testaceous ; antennae black, ex- 

 tending one third the length of the body, apical joints long. Thorax 

 about twice as broad as long, scarcely widened in the middle, sides 

 nearly straight, the anterior angles produced and pointed ; surface 

 with a few distinct punctures near the base ; tlie disk remotely and 

 finely punctate, with a deep round fovea at each side, and anotlier 

 oblique shallower depression at the lateral margin, as well as the scu- 

 tellum, black. Elytra oblong, convex, rather closely and deeply 

 punctate, the punctures forming irregular double rows near the 

 suture, but confusedly arranged at the rest of the surface. Under- 

 side and legs black. 



33. Prosicela bicruciata, sp. nov. 



Oblong-ovate. Greenish black, siiiuing ; elytra deeply punctate- 

 striate, flavous ; the suture, a short transverse oblique band below the 

 base, common to both elytra, and another larger one behind the 

 middle greenish black. 



Length 5 lines. 



Head with a fine central groove and a few irregularly distributed 

 punctures ; labrum piceous, finely margined with testaceous ; an- 

 tennae extending to half the length of the body, greenish black. 

 Thorax twice as broad as long, its sides nearly straight, and the 

 anterior angles produced into a point ; surface very minutely punc- 

 tured, with a few remotely placed deeper punctures near the base 

 greenish black; scutellum impunctate. Elytra with about ten rows 

 of rather deep punctures, visible to the naked eye, the punctures 

 running in double lines towards the lateral margin ; the others con- 

 sisting of single rows, but meeting at their ends at the apex, where 

 the interstices are raised into costa; ; they are of a light flavous 

 colour, with a short transverse greenish-black band across the 

 suture below the base having an upward direction, and another more 

 irregular-shaped band, and lioUowcd at its anterior margin, ex- 

 tending nearly to the sides, below the middle ; the suture also is 

 of the same colour, but gradually narrowed to the apex ; claws 

 simple. 



Genus Doryphora, Illig. 



34. Doryphora punctatissima, Oliv. 



35. Doryphora batesi, Baly. 



36. Doryphora princeps. Gray. 



37. Doryphora fulgora, Stal. 



The Ecuador specimens are devoid of the fulvous spots of the 

 head and thorax, and approach nearer to D. celsa, Erichs. ; the 

 coarser sculpturing of the elytra and the elongate term.inal joint of 

 the antennae, however, distinguish it from that species. 



38. Doryphora rubropunctata, De Geer.
