CHRTSOMELIDjE. 
I have received a single specimen from Mr. E. Green from Ceylon. 
The species is distinguished by the moderately widened inter- 
mediate joints of the antennae and the nearly impunctate posterior 
portions of the elytra. 
55. Lema mandibnlaris, Jac. Ann. Mus. Civ. Genova, xxxii, 1892, 
p. 870. 
Eulvous; antennae (basal two joints excepted), labrum and tarsi 
black. 
Head not constricted posteriorly ; the eyes elongate, impunctate, 
the vertex with two smooth tubercles, the ocular grooves rather 
feebly marked; labrum, clypeus and mandibles black, the latter 
very robust and strongly produced ; antennae black, scarcely extend 
to half the length of the elytra, the basal two joints fulvous, 
third and fourth joints equal. Thorax slightly broader than long, 
the sides only moderately constricted, the basal sulcus deep ; the 
surface impunctate, fulvous. Elytra fulvous with a slight aeneous 
lustre, the base very slightly depressed at the suture ; the punctures 
as usual, much finer posteriorly ; the interstices flat, impunctate, 
slightly costate at the sides and apex. Underside clothed with 
fulvous pubescence, tarsi black. 
Length 6 mm. 
Hob. Burma : Palon. 
The produced anterior portion of the head and the strongly 
developed mandibles distinguish this species from any other 
Eastern form with which I am acquainted. 
56. Lema singularis, sp. n. 
Entirely fulvous. 
Head constricted behind the eyes, the latter very large and 
prominent, the sulci deep ; the vertex not tuberculate, with the 
usual short groove ; penultimate joint of palpi distinctly thickened, 
its apex acute ; antennae fulvous, long and slender, the third joint 
distinctly shorter than the fourth. Thorax slightly longer than 
broad, the anterior angles with an extremely small tubercle, lateral 
constrictions moderate, deeply excavate at the sides with an acute 
ridge above; basal sulcus rather deep; placed at some distance 
from the base. Scutellmn subquadrate. Elytra with a feeble 
basal depression, the punctures strong at the base, fine from 
before the middle to the apex, rather remotely placed, the shoulders 
very prominent. 
Length 6 mm. 
Hob. Assam : Patkai Mts. {Doherty). Type in Brit. Mus. 
The incrassate palpi, the elytra only slightly depressed at the 
base and the proportionately long thorax clearly distinguish this 
species, of which three examples are before me. It is one of the 
few Indian Lemas which have the third joint of the antennae 
perceptibly shorter than the fourth ; the thorax is distinctly 
longer than that of L. palpalis.
