18HI.] ON NEW PHYTOPHAGOUS COLEOPTERA. 439 



5. Descriptions of new Genera and Species of Phytophagous 

 Coleoptera. By Martin Jacoby. 



[Eeceiyed March 5, 1881.] 



Genus Lamprosph^rus, Baly. 



1. Lamprosph.erus gigas, sp. nov. 



Rotundate-ovate, convex. Metallic green ; base of antennae and 

 the tarsi fulvous ; thorax irregularly and rather finely, elytra more 

 strongly, siihstriate-punctate. 



Length 3 lines. 



Hab. Peru. 



Head distinctly and rather closely punctured, with a central 

 longitudinal groove ; clypeus wedge-shaped, distinctly separated 

 from the face, impunctate ; labrum and jaws black. Antennae two 

 thirds the length of the body, the three basal joints fulvous, the rest 

 black. Thorax transversely convex, its sides much narrowed towards 

 the base, posterior margin oblique at each side, the median lobe but 

 little produced ; surface closely and irregularly covered with larger 

 and smaller punctures. Elytra very convex, with a shght transverse 

 depression below the shoulders, the latter rather prominent ; surface 

 strongly and rather regularly punctate-striate, less strongly towards 

 the apex. Underside and legs metallic green, tarsi fulvous. 



In my collection. 



The large size of this species will distinguish it from the others 

 described, L. tarsatus, Baly, being most nearly allied to it ; from 

 that species, however, the metallic green upperside and the strong 

 punctuation of the elytra separate it. 



2. Lamprosph^rus subcostatus, sp. nov. 



Rotundate-ovate, convex. Black ; base of antennae and the legs 

 and tarsi fulvous ; above dark blue, shining ; thorax finely and 

 closely, elytra deeply punctate-striate, the interstices laterally costate. 



Length 2 lines. 



Hnb. Bogota. 



Head rugose-punctate ; labrum fulvous. Antennae subfiliform ; 

 the last five joints slightly dilated, piceous ; first five joints fulvous. 

 Thorax three times as broad as long, sides evenly rounded, finely 

 margined with metalhc green, surface closely hut rather finely punc- 

 tured. Scutellum ovate, smooth. Elytra as wide as the thorax, 

 narrowed and rather pointed towards the apex ; surface deeply and 

 regularly punctate-striate, with three or four distinct costae near the 

 lateral margin. Underside black ; legs entirely fulvous. 



Collection Jacoby. 



Genus Ph^dra, Chapuis. 



3. Phaedra buckleyi, sp. nov. 



Broadly ovate, subrotundate, convex. Below black ; antennae.
