27. Monolepta batuensis, n. sp. — Flavous, the breast piceous ; 

 thorax subquadrate with a centrai black band, elytra very finely 

 and closely punctured, a spot on the shoulders and a transverse 

 sinuate band at the middle, obscure piceous or fuscous, tibiae 

 of the same colour. 



Length 4 mill. 



Of elongate shape, tlie head impunctate, flavous or pale ful- 

 vous, the clypeus broad, impunctate, ending in a distinct ridge 

 between the antennae , the latter nearly extending to the end 

 of the elytra, flavous, the basal joint elongate, curved and slender, 

 the second short, the third twice as long as the seconil but 

 shorter than the fourth joint, the apex with an additional twelfth 

 joint ; thorax one half broader than long, the sides straight at 

 the base, slightly rounded at tlie middle, the surface obsoletely 

 transversely depressed at the middle, nearly impunctate, flavous, 

 with a central black longitudinal narrow stripe, the sides also 

 stained with an obscure piceous spot, scutellum small, piceous; 

 elytra convex , finely and very closely punctured , the base of 

 each with an elongate pear-shaped fovea , the ground colour a 

 greenish flavous, the slioulders with an elongate piceous spot 

 which is joined by a narrow stripe at the sides, with the trans- 

 verse band placed at the middle, this band is not well defined 

 posteriorly where it gradually dissolves into the ground colour 

 of the elytra, but its anterior edge is distinct and deeply bisi- 

 nuate, the underside and the femora flavous, the breast and the 

 tibiae and tarsi more or less piceous, the metatarsus of the 

 posterior legs very long, all the tibiae mucronate, the anterior 

 coxal cavities closed; elytral epi pleurae extremely narrow below 

 the middle. 



This Monolepta is interesting on account of the very distinct 

 twelve-jointed antennae , the additional joint being proportio- 

 nately much longer than in several cases of similarly structured
