28 CHBYSOMELID^. 



SECTION V. 



Thorax ivith single basal sulcus. Colour above testaceous, pale 

 or dark fulvous. Species of large size (7-10 mm.). 



46. Lema atkinsoni, sp. n. 



Broad and robust ; antennae (basal two joints excepted), tibiae 

 and tarsi black. 



Head constricted posteriorly, impunctate; eyes large, deeply 

 notched, the vertex with an obsolete groove, scarcely raised, the 

 lateral grooves deep. Antennae black, extend to slightly beyond the 

 base of the elytra, the basal two joints flavous, the third and fourth 

 short and equal, basal four joints shining, the rest opaque, 

 pubescent, terminal joints subcylindrically widened, twice as long 

 as broad. Thorax broad and flat, deeply constricted at the sides, 

 the anterior angles strongly produced and rounded, the lateral 

 cavities bounded by an acute ridge above ; the disc with several 

 rows of fine punctures, otherwise impunctate. Scutellum narrow, 

 flavous. Elytra with the shoulders oblique, the basal portion 

 neither raised nor depressed, the inner four or five rows of punctures 

 at the base strong, rest of the surface finely punctured, all the rows 

 consist of single punctures, the interstices sparingly and minutely 

 punctate. 



Length 10 mm. 



Hob. Sikhim : Mungphu. Type in Brit. Mus. 



Allied to L. bohemanni, Clark, from China (russula, Boh.), from 

 which species the insect described above differs as follows : no 

 basal depression near the suture ; interstices not smooth but finely 

 punctured. 



47. Lema rufo-brunnea, sp. n. 



Dark brown ; the antennae, tibiae and tarsi black. 



This is so closely allied to the preceding species that it will be 

 sufficient to point out the differences. It has nearly the same 

 broad and robust shape but is of a dark brown, not flavous, colour ; 

 the antennae are entirely black and of a rather more slender shape ; 

 the thorax is somewhat longer and not nearly so deeply constricted 

 nor widened anteriorly as in L. atkinsoni, and the elytra are rather 

 more strongly punctured ; in all other respects the two species are 

 alike. 



Length 9| mm. 



Hub. Assam : Patkai Mts. Type in Brit. Mus. 



48. Lema peguensis, pp. n. 



Dark brown, head and thorax nearly black. 

 Of rather flattened shape. Head distinctly bituberculate at the 

 vertex, eyes moderately deeply notched ; antennae stout and rather
