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



5. On a Collection of Phytopliagous Coleoptera made by Mr. 

 Buckley at Eastern Ecuador, By Martin Jacoby. 



[Received September 7, 1880.] 



(Plates LIV.-LV.) 

 Although the series of Phytophaga collected by Mr. Buckley 

 during his last travels in Ecuador is not very numerous and is 

 devoid of the smaller species of HalticidcB and Galerucidce, it 

 nevertheless contains a good many new and interesting species, of 

 •nhich a great part are not only inhabitants of Ecuador, but have 

 ftlso been found either in Peru or the Amazonian region. The 

 insects here described are in the collection of Messrs. Godmau and 

 Salviu and my own. 



Genus Lema, Fab. 



1. Lema viridana, sp. nov. 



Oblong, parallel; Flavous ; head, antennae (the two apical joints 

 excepted), tibiae, and tarsi black ; elytra deeply punctate-striate, 

 metallic green, the lateral margin and the apex flavous. 



Length 3| lines. 



Head rather deeply constricted behind the eyes, the vertex with a 

 small fovea ; front deeply grooved on either side, the intermediate 

 space and the clypeus impunctate, shining black ; antennse half the 

 length of the body, black, the last two joints and part of the preceding 

 flavous. Thorax a little broader than long, sides rather deeply con- 

 stricted, the basal transverse groove deep and distinct; surface 

 smooth, flavous, shining ; scutellum black. Elytra very slightly con- 

 stricted laterally before the middle, deeply pimctate-striate, the in- 

 terstices strongly raised towards the apex, anteriorly here and there 

 transversely wrinkled and minutely punctate. Underside, with the 

 exception of the upper part of the bieast, which is black, as well as 

 the underside of the femora and tibia, flavous ; tarsi black. 



From L.cincta, Lac, distinguished by the black head, the colour 

 of the antenna:;, and the strongly raised elytral costa ; from L. liiiiba- 

 iipennis, Jacoby (Journ. IMunich Entom. Soc. 1878), by the black 

 anteuHBe and the colour of the legs. 

 Mus. Jacoby. 



2. Lema semicyanea, sp. nov.
