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 1 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. 

 Antenna 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. 



Hob. 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 antennas 

 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 ; antennas 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
