SOUTH AMERICAN PHYTOPHAGOUS COLEOPTERA. 2^9 



separate the species from L. trilineata, Lac, and others of the 

 same division ; the narrow elytral blue stripes from L. boliviano,. 

 Four specimens are contained in my collection. 



Lema speciosa, sp. no v. 



Flavous ; the head, antennas (the apical joints excepted), the 

 anterior and posterior margins of the thorax, and the tibial and tarsi 

 black ; elytra metallic blue, the lateral margins and the apex more 

 broadly flavous. Length, 7 mill. 



Head black, impunctate, very shining ; the eyes deeply notched ; 

 antennas black, the apex of the nmth and the apical two joints flavous ; 

 thorax not longer than broad, the anterior angles rounded, the surface 

 with a few fine punctures, flavous, the basal sulcus rather shallow, 

 the disc with a narrow anterior and posterior black band, the latter 

 narrower than the anterior band ; scutellum black ; elytra with a very 

 slight sutural depression below the base, strongly punctured anteriorly, 

 the interstices at the same place slightly transversely convex, the 

 others rather strongly longitudinally costate from the middle down- 

 wards, the entire disc metallic dark blue, the lateral margins narrowly 

 and the apex more broadly flavous, the under side and the femora of 

 the latter colour ; the tibias and tarsi black. 



Hab. Peru. 



A species allied to L. limbatipennis, Jac, L. flavomarginata, 

 Clark, and several others ; but distinguished from all by the 

 markings of the thorax in connection with the flavous joints of 

 the antennas and similar coloured under side. 



Lema boliviano, sp. nov. 



Black ; the thorax impunctate, very shining ; elytra much wider 

 than the thorax, with basal depression, flavous, closely and strongly 

 punctate-striate ; abdomen flavous. Length, 8 mill. 



Head black, shining, strongly constricted behind the eyes, the latter 

 deeply notched ; clypeus acutely pointed between the antennas, the 

 latter black, long, extending a little beyond the middle of the elytra, 

 robust, the fourth joint one-half longer than the third, the following 

 joints equal ; thorax as broad as long, deeply constricted at the middle, 

 the basal sulcus deep, placed immediately below the middle, the 

 anterior angles rounded, the surface very shining, black, with a slight 

 bluish gloss, entirely impunctate ; scutellum black ; elytra broad, dis- 

 tinctly depressed below the base, pale flavous, closely and rather 

 strongly punctate-striate, the ninth row entire, the interstices slightly 

 costate near the apex ; the breast and legs black ; the abdomen flavous^ 



Hab. Bolivia. 



The elytra in this species are broader at the base than in 

 most cases in this genus, making the thorax appear compara- 

 tively small. This and the uniformly coloured pale flavous 

 elytra in connection with the black head, antennas, and legs will 

 help to distinguish the species.
