LEM A.

constricted at the sides, the basal groove likewise deep, anterior 
angles slightly pointed but not tuberculate ; the surface convex 
and swollen, impunctate. Elytra broad, subquadrate, the base 
scarcely depressed, the puncturation deep and not very closely 
placed anteriorly, much more closely posteriorly, the punctures on 
that portion run into striae; the interstices costate. Underside 
fulvous, clothed with yellow pubescence. Legs fulvous, robust. 
Length 6 mm. 
Hab. Ceylon. 
Can be at once separated from L. subobliterata by the feeble 
elytral depression and their different sculpture. 
24. Lema nigro-frontalis, Clark, App. Cat. Phytoph. 1866, p. 40. 
Head, thorax and legs rufous; labrum and underside piceous 
or black ; antennae fuscous ; elytra metallic blue. 
Head with the frontal elevations strongly raised, divided 
posteriorly, sparingly punctured ; antennae with the lower two 
or three joints rufous, rest nearly black or fuscous, fifth and 
following joints elongate, third and fourth equal. Thorax with 
anterior augles not tuberculate ; the lateral constriction forms 
a deep cavity, bounded above by a perpendicular ridge ; basal 
sulcus deep, foveolate at middle. Elytra with short and moderately 
deep depression below base, punctures closely placed and rather 
deep anteriorly. 
Length 6 mm. 
Hab. Northern India ; Nepal ; Bengal. 
Differs from the preceding species in the dark antennae and 
closely placed elytral punctures ; the thorax has two rows of fine 
punctures. 
25. Lema birmanica, Jac. Ann. Mus. Civ. Genova, xxxii, 1892, p. 872. 
Keddish-fulvous, labrum black ; elytra dark blue, extreme apex 
fulvous. 
Head impunctate, not constricted posteriorly, the frontal 
elevations distinct, divided by a narrow longitudinal groove ; 
labrum bluish-black ; antennae extended to half the length of 
the elytra, entirely fulvous. Thorax slightly broader than long, 
moderately constricted at the sides, the basal sulcus very deep 
followed by another more obsolete transverse groove, the surface 
impunctate. Scutellum fulvous. Elytra slightly depressed below 
the base, the punctures deep and large anteriorly, gradually 
diminishing towards the apex, the latter narrowly fulvous. 
Length 6 mm. 
Hab. Burma : Palon ; Tenasserim : Malewoon. 
Very closely allied to L. stevensi , Baly and has nearly the same 
colouring, but the head is not constricted ; the thorax is entirely 
impunctate, as are also the elytral interstices, which differ in 
colour from those of the preceding species.
