CHRYSOMELIDiE. 
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 labrurn 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.

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. 
Bufo-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 tibia3 and tarsi darker, sometimes the femora also 
dark. 
Length 4-4| mm.
