412 PHYTOPHAGA. 



Head impunctate, deeply transversely grooved between the antennae ; antennae entirely black, the intermediate 

 joints slightly dilated ; thorax three times as broad as long, narrow, pale flavous, the sides rounded and 

 moderately flattened, the anterior angles not greatly produced but thickened, the surface entirely im- 

 punctate, shining ; scutellum obscure piceous ; elytra rather widened and convex posteriorly, finely and 

 closely punctured, metallic violaceous blue, their extreme apices in the shape of a narrow triangular 

 flavous or fulvous spot ; underside and femora fulvous or flavous ; tibia? and tarsi nearly black. 



Hab. Guatemala, Purula [Champion). 



There is scarcely any difference, except in size, between the five specimens obtained. 

 (E. purulensis differs from (E. extrema, Harold, by the absence of the flavous elytral 

 margin.

12. (Edionychis hogei. 



Fulvous ; antenna? and tarsi fuscous or black ; elytra violaceous blue, the extreme apices flavous. 

 Length 3 lines. 



Head impunctate ; the two or three basal joints of the antennae fulvous, the rest fuscous ; thorax impunctate ; 

 elytra finely and closely punctured. 



Hab. Mexico, Jalapa, Oaxaca (Edge), Cordova (Hbge, Salle). 



Whether this species is really distinct from (E. purulensis or only a local variety I 

 am not able to decide, as no intermediately coloured specimens are before me ; those 

 from the above localities, to the number of six, a]l differ from the allied species in the 

 fulvous head, thorax, and tibiae, and in the similarly coloured basal joints of the 

 antennae. (E. hogei is therefore probably specifically distinct from (E. purulensis, with 

 which it agrees, however, in all other respects. 



13. (Edionychis extrema. 



(Edionychis extrema, Harold, Deutsche ent. Zeitschr. 1880, p. 221 1 . 

 Hab. Mexico 1 , Tuxtla (Salle). 



The colour of the elytra in this species varies from blue to nearly black, and the testa- 

 ceous apical spot is either isolated or connected with the similarly coloured narrow 

 lateral margin ; the colour of the latter separates (E. extrema from (E. hogei and (E. 

 purulensis. A closely allied species, but with the underside black, the (E. beskii of 

 Clark's Catalogue, is found in Brazil. A specimen so named by this author is con- 

 tained in the Baly collection from the latter locality; another one from the same 

 country I possess, so that the locality " Mexico," as given by Clark, seems erroneous. 



14. (Edionychis lateralis. 



Light fulvous below; thorax testaceous, with some obscure fulvous spots; etytra closely and distinctly 

 punctured, metallic blue or black, their extreme lateral margin and their apices fulvous. 



Length 3-4 lines. 



Head entirely fulvous, with a few deep punctures near the inner margin of the eyes ; antenna? black, the first 

 three joints fulvous ; thorax narrowly transverse, the anterior angles produced into a blunt tooth, the 

 disc impunctate and obscurely stained with dark fulvous spots, assuming the shape of a y at the middle ; 

 elytra extremely closely and subrugosely punctate, the fulvous lateral margin very narrow, but widened at
