distinctly longer antennae of the last-named insect ; the latter is 
found in Borneo, Sumatra, &c., but has not been recorded from 
India, where L. lacordairei takes its place. 
Length 7 mm. 
Hob. Southern India : Malabar ; Nilgiris ; Burma. 
39. Lema andamanensis, sp. n. 
Fulvous ; elytra metallic blue. 
Head with an interrupted median groove, without frontal 
elevations, impunctate, the lateral sulci very deep ; eyes large, 
acutely but not very deeply notched ; clypeus elongate, wedge- 
shaped, convex and impunctate, fulvous as is also the labrum. 
Antennas robust, with cylindrical joints, entirely fulvous ; basal 
joint short, subquadrate, second moniliform, third and fourth short, 
equal, fifth joint but slightly longer than the following, which 
are covered with very fine fulvous pubescence. Thorax slightly 
longer than broad, moderately constricted at the sides ; the basal 
sulcus well marked, ending laterally in a deep cavity, the latter 
blackish and bounded above by a short perpendicular ridge ; the 
surface entirely impunctate. Scutellum subquadrate, fulvous. 
Elytra with short but deep humeral sulci, the punctures round and 
deep, rather distantly placed, the first sutural row not double 
anteriorly, the posterior portion more finely punctured ; the sutural 
and the three or four lateral interstices more or less convex, the 
others with some fine and distant punctures. Body beneath and 
the legs fulvous, very sparingly clothed with short yellow 
pubescence. 
Length 6 mm. 
Hah. Andaman Islands (Coll. Jacoby). 
Differs from L. fulvicornis, Jac. in the fulvous, not black, 
labrum, in the vertex of the head, which is not swollen nor 
punctured, also in the shorter terminal joints of the antenna 
which, are subquadrately flattened, although longer than broad. 
L. cyanipennis, Fab. has a longer thorax, a deep elytral depression, 
and is much more finely punctured. In L. mouhoti, Baly, the 
thorax is more swollen and the elytra are deeply depressed below 
the base. 
40. Lema amethystina, sp. n. 
Ferruginous ; clothed with goldenpu bescence beneath ; elytra 
violaceous. 
Elongate and parallel-sided, the head constricted posteriorly, 
entirely impunctate, the vertex, not divided ; antennae pale ferru- 
ginous, extended to just below the base of the elytra, the joints 
robust, the third distinctly shorter than the fourth. Thorax 
slightly longer than broad, strongly constricted at the middle, the 
lateral cavities very deep, anterior angles thick and rounded, basal 
sulcus only indicated ; the disc with a few very minute punctures
