290 CHRYSOMELIDJE. 



495. Chrysolampra viridicollis, sp. n. 



c? . Metallic green; antennae and legs fulvous; elytra dark blue. 

 Head extremely closely and rather finely rugosely punctured; 

 clypeus not separated from the face, rather more strongly punc- 

 tured ; labrum fulvous; antennae nearly extending to apex of elytra^ 

 fifth and following joints half as long again as the third and fourth. 

 Thorax about half as broad again as long, sides rounded, narrowly 

 margined ; surface convex, very strongly and closely punctured ; 

 interstices irregularly rugose, especially so at the sides. Scutellum 

 metallic green. Elytra wider at base than the thorax, extremely 

 closely and strongly punctured, interstices finely wrinkled, apical 

 portion near suture longitudinally costate. Body beneath metallic 

 green. 



$ . Above entirely metallic green ; the head has a distinct 

 central longitudinal depression, the thorax is rather less closely 

 punctured, and the elytra have some narrow smooth longitudinal 

 lines ; but in all other respects, except in coloration, the two

Hob. Burma : Ruby Mines. Type in Brit. Mus. 



I only know a single pair, male and female, of this handsome 

 species. The male has, as usual, the first joint of the anterior 

 tarsi dilated. 



The elytral puncturation is much stronger and closer than in 

 C.flavipes, the coloration of the upper parts is also quite different. 

 From C. indica this species differs in the finely and closely rugose 

 head, the strongly and closely punctured elytra, general larger size 

 and fulvous legs. C. burmanica, Jac., has a remotely and finely 

 punctured thorax and broadly reflexed lateral thoracic margins. 

 In C. thoracica, Jac., the sculpturing of the thorax and elytra is 

 different. Lastly, C. subcenea, Jac., and C. fiavipes, Jac. have 

 finely and sparsely punctured heads. 



496. Chrysolampra bicolorata, sp. n. 



Violaceous ; beneath metallic green ; labrum fulvous ; antennae 

 (basal joints excepted) and legs black. 



Head broad, closely and strongly punctured, interstices very 

 finely pubescent ; clypeus bounded above by a transverse ridge at 

 the sides, and with an elongate tubercle in the middle, strongly and 

 closely punctured like the head, anterior edge but slightly concave ; 

 mandibles robust, black ; antennae slender, basal joint beneath and 

 the following three joints entirely pale fulvous, third and fourth 

 joints equal, remainder longer and very slender. Thorax twice as 

 broad as long, sides evenly rounded, anterior angles produced into 

 an acute point ; surface strongly and irregularly punctured, 

 punctures closely placed at the sides. Scutellum impunctate. 

 Elytra broad, wider at base than the thorax, shoulders prominent ; 

 entire surface impressed with round and closely placed deep 

 punctures, much larger than those on the thorax ; interstices more
