CHEYSOMELIDJE. 
with a small transverse impression below the base, finely 
punctate-striate except at the base where the punctures are larger, 
the first row near the suture single, the interstices with some 
minute punctures here and there, slightly costate near the apex. 
Legs rather short, bluish-black. Underside clothed with fine grey 
pubescence. 
Length 5 mm. 
Hob. Tenasserim (Doherty), Andaman Islands (Roepstorjf). 
Type in Brit. Mus. 
A narrow, elongate species, of more or less dark blue colour, 
distinguished by the fulvous labrum, the widened intermediate 
joints of the antennae and the punctured elytral interstices ; there 
are some slight differences present in the Andaman specimens but 
these are not sufficient to justify separation. Thus the thorax 
is not perceptibly punctured, the elytral depression is very small 
and feeble and their puncturation finer, but these differences are 
probably racial not specific ; all other characters are identical. 
126. Lema crebrepunctata, sp. n. 
Metallic dark blue ; antennse black. 
Bather flattened above ; the head not constricted, the vertex 
convex, not tuberculate, with a short deep central groove 
anteriorly ; eyes very prominent, not very deeply notched ; lower 
portion of face seneous ; antennse long and slender, third and 
fourth joints short, equal, following joints very elongate. Thorax 
quadrate, the lateral constrictions deep, furnished within with 
short perpendicular ridges, the basal sulcus deep ; the anterior 
portion seneous, the base blue, anterior angles very slightly 
tuberculate. Scutellum rather broad, seneous. Elytra slightly 
narrowed posteriorly, with a small, rather shallow basal depression ; 
the punctures large, round and deep, very closely placed, the 
interstices costate over the greater portion of the disc. Underside 
and legs bluish-black. 
Length 4 mm. 
Hob. Burma : Bubv Mines (Doherty). 
Allied to L.cyanect , Fabr.,but of narrower, more cylindrical shape, 
generallv of smaller size ; the thoracic constriction furnished 
with ridges, the elytral puncturation much stronger and the 
interstices more or less costate. 
127. Lema atro-cserulea, Clark, App. Cat. Phytoph. 1866, p. 32. 
Black ; elytra with slight bluish gloss. 
Head impunctate, intraocular space not strongly raised, lateral 
sulci rather feeble ; palpi fulvous ; antennae black, long and slender, 
the third joint shorter than the fourth, the following joints very 
elongate, terminal three joints shorter. Thorax with the anterior 
angles pointed but not tuberculate, black, shining, the surface not 
perceptibly punctured, basal sulcus very deep. Elytra with a very
