156 CHRYSOMELIDvE. 



Head entirely impunctate with two feeble transverse depressions 

 between the eyes ; clypeus very broad, impunctate, its anterior 

 margin only slightly emarginate ; eyes elongate, nearly entire ; 

 antennae with the basal four joints flavous, the rest fuscous. 

 Thorax nearly twice as broad as long, scarcely narrowed anteriorly, 

 the lateral margins feebly rounded, with narrowly reflexed edges ; 

 anterior angles acute, posterior obtuse, the surface entirely im- 

 punctate even when seen under a very strong lens. Scutellum 

 broad, pointed, the basal margin black. Elytra subcylindrical, 

 somewhat strongly lobed below the shoulders, their epipleurse 

 continued behind the middle ; the surface finely but distinctly 

 punctured, with a transverse, metallic, bluish-black band behind 

 the middle, not extending to the extreme sutural or lateral 

 margins ; the edges of this band irregularly notched. Body 

 beneath black, densely pubescent ; legs fulvous. Tarsi short and 

 broad. 



Length 6| mm. 



Hcib. Northern India. Type in Brit. Mus. 



A single $ specimen of this species is before me ; it is rather 

 closely allied to O. plagiata, Duv., but differs in the entirely 

 impunctate head and thorax, the blue, not black, elytral band and 

 the black underside. 



274. Clytra annamita, Lefev. Ann. Soc. Ent. France, 1889, p. 288. 



Fulvous ; head with two, thorax with one black spot ; elytra 

 with one transverse black band before and another behind the 

 middle, the first band not extending to suture ; breast and 

 abdomen more or less black. 



Elongate, subcylindrical. Head impunctate, obsoletely trans- 

 versely grooved between eyes ; vertex with two black spots ; 

 antennae fuscous, basal four joints flavous, fifth and following 

 joints strongly transversely serrate. Thorax not quite one-half 

 broader than long, subcylindrical, sides nearly straight, surface 

 impunctate. Elytra scarcely perceptibly punctured, a short, 

 rather distinct row of punctures near suture, both bands of 

 irregular shape and narrowed in the middle. Tarsi broad and 

 equal. 



Var. a. Elytral bands replaced by four spots, placed transversely 

 before and behind the middle. 



Var. b. Head and thorax without spots. 



Length 6-7 mm. 



Hob. Burma : Eangoon, Palon. Cochinchina : Saigon. 



Larger than either C. occipitalis or C. cardoni, the elytra less 

 spotted and the position of the bands different ; in a specimen 

 named by Lefevre there is an additional spot at the extreme apex 

 of the elytra which the author does not mention.
