20 CHRYSOMELID^E. 



30. Lema balyana, sp. n. 



Black ; upper portion of head and the thorax fulvous ; elytra 

 metallic blue. 



Head not constricted posteriorly, the vertex with two broad, 

 rather highly raised elevations ; eyes narrowly notched ; the clypeus 

 and labrum black, both rather elongate ; antennae black, pubescent, 

 extended to the middle of the elytra, the third joint slightly 

 shorter than the fourth, the following elongate cylindrical. Thorax 

 rather transverse, the anterior angles barely prominent, the lateral 

 constrictions sulciform and connected with the basal sulcus, the 

 latter placed at some distance from the basal margin ; the anterior 

 portion of the thorax with a slight transverse depression at the 

 sides, only seen in certain lights, the disc with a few very minute 

 punctures. Scutellum fulvous or black. Elytra narrowed towards 

 the apex, subcylindrical, with a short but not deep basal depression, 

 metallic blue ; the punctures regular, only slightly larger at the 

 base than posteriorly, the rows closely placed, the interstices at 

 the apex not costate. Underside and legs black, the latter elongate 

 and slender. 



Length 5| mm. 



Hub. Travancore: Wallardi (Coll. Jacoby); Nilgiris (H. L. 

 Andrewes). 



Principally distinguished by the black antennae, underside and 

 legs, as well as the clypeus and labrum. The species is closely 

 allied to L. rothschildi, Clavar. (nigrilabris, Jac.), from Nyassaland, 

 but differs in the entirely black antennae and the non-tuberculate 

 anterior portion of the thorax, also in the non-costate elytral 

 interstices. 



31. Lema horni, Weise, Deut. ent. Zeit. 1903, p. 21. 



Rufo-testaceous ; the labrum, antennae, and the legs more or 

 less fuscous ; breast and abdomen piceous ; elytra black, with a 

 slight bluish tint. 



A small and slender-shaped species with but slightly convex 

 black elytra, the latter with a bluish gloss and not very shining. 

 Frontal elevations of the head punctured and pubescent, feebly 

 divided. Thorax closely and very finely punctured, with two 

 rows of punctures at the middle ; the basal sulcus deep, widened 

 into a deep cavity at the sides which strongly constricts the 

 thorax, the anterior angles rounded. Scutellum reddish, smooth. 

 Elytra scarcely depressed below the base, regularly punctate- 

 striate, the interstices convex at the apex and sides only. Legs 

 reddish, the tibiaa and tarsi darker, sometimes the femora also 

 dark. 



Length 4-4| mm.
