320 CHRYSOMELLDjE. 



Head entirely impunctate ; clypeus distinctly separated from 

 the face, its margins raised, anterior edge semicircularly emarginate, 

 surface entirely smooth ; antenna? with the basal four joints and 

 part of the fifth pale fulvous, rest blackish, third and fourth joints 

 equal. Thorax half as broad again as long, scarcely narrowed in 

 front, sides rounded, anterior sulcus entire, surface not perceptibly 

 punctured. Elytra ovate, very feebly depressed below the base, 

 with two or three rows of fine punctures near the suture, rest of 

 surface impunctate, very shining ; a broad sutural band, black, 

 extending from base to apex and widened at the apex. 



Length 3 mm. 



Hob. Bengal (Coll. Jacoby). 



554. Nodostoma andamanense, sp. n. 



Fulvous ; sutural and lateral margins of elytra narrowly black. 



Head with two or three fine punctures only ; clypeus strongly 

 punctured at base, deeply emarginate, angles strongly pointed ; 

 mandibles black ; antennae flavous or fulvous, very slender, third 

 joint slightly shorter than the fourth. Thorax twice as broad as 

 long, of even width, sides strongly rounded, anterior sulcus distinct, 

 surface very remotely and finely punctured at the sides. Elytra 

 elongate, pointed at apex, very deeply transversely sulcate below 

 the base and within the shoulders, distinctly punctured within 

 depression and with two or three rows of punctures near the 

 suture, apical portion strongly deflexed and nearly impunctate, a 

 short oblique costa below the shoulders, sutural margins strongly 

 raised. 



Far. Elytra entirely fulvous. 



Length 3 mm. 



Hob. Andaman Islands ( Colls. Brit. Mus. $ Jacoby). 



The strong deflexion of the posterior portion of the elytra can 

 best be seen when the insect is viewed sideways. The punctura- 

 tion of the thorax is distinct only at the sides, where it is arranged in 

 somewhat regular longitudinal rows : this character and the strongly 

 rounded sides and shape of the elytra will help to distinguish this 

 species. The specimens before me are apparently females. 



Above fulvous ; sides of thorax generally ungulate. 



555. Nodostoma obliteratum. Jac. P. Z. S. 1887, p. 80. 



Pale fulvous, subelongate. Head and clypeus with a few fine 

 punctures, the anterior border of the latter semicircularly emar- 

 ginate ; antennre flavous, extending very nearly to apex of elytra, 

 third joint much shorter than fourth, terminal joints more or less 

 fuscous. Thorax twice as broad as long (not three times, as 

 originally given), sides angulate near the base, strongly obliquely 

 narrowed in front, anterior sulcus deep and entire, surface very 

 sparingly and finely punctured. Elytra slightly broader than the 

 thorax, with rather shallow basal, short depression, sparsely
