32 CHBYSOMELID^. 



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 mandibularis, j a c. Ann. Mus. Civ. Genova, xxxii, 1892, 



p. 870. 



Fulvous ; 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 ; antennas 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. 



Hab. 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. Scutellum 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. 



Hab. 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.
