base, and besides these the whole surface is covered with extremely 

 minute punctures. Scutellum smooth, impunctate. The elytra 

 and underside call for no special remark. 

 Length, 9g-10 mm.; breadth, 5|-5| mm.

Genus CREPXDODERA, Chevrolat. 



Crepidodera Chevr., in D'Orbigny, Diet. Univ. Hist. Nat. iv, 1844^

Genotype, Chrysomela nitidula, L. (Europe). 



Chevrolat founded this genus on the presence, in frout of the 

 basal line of the pronotum, of a transverse impression, bounded 

 on each side by a raised fold. He, moreover, cited many Linneau 

 and Fabrician species, including them in this genus. At present 

 the presence of the four following characters in a beetle of this 

 group will distinguish it from all the other genera: (1) the 

 thickened hind femora, (2) the closed anterior coxal cavities, (3) 

 the fact that the coxae are only slightly distant, (4) the antebasal 

 pronotal channel. These beetles are oval or oblong-oval ; the 

 Indian species are very small (one and a half or two millimetres 

 in length). Head with front carinate or depressed. Antennae 

 generally long, more than half the length of the body, with the 

 apical segments slightly thickened or, at any rate, not attenuated ; 

 first segment long, second oblong-oval, half the size of the first, 

 third and fourth subequal ; the following more elongated and 

 gradually thickened; this is generally the structure, but it varies 

 to a certain extent. Protliorax subquadrangular, somewhat broader 

 than long, sides slightly rounded, lateral edges sometimes serrated; 

 surface convex with a large and deep impression along the posterior 

 margin, limited on either side by a small longitudinal depression*. 

 Scutellum triangular. Elytra oblong or oval, moderately convex 

 and more or less punctate-striate. Underside: prosternum mode- 

 rately narrow, convex, depressed behind and produced so that, 

 meeting the extensions of the epimera, it closes the anterior coxal 

 cavities behind; posterior femora moderately thickened ; posterior 

 tibiae sometimes more or less channelled or depressed and provided 

 at the apex with an extremely small sharp curved spine ; tarsal 

 claws appendiculate. 



Range. World-wide. 



* These longitudinal impressions are absent in C. minuta, which, as stated 

 below, is somewhat doubtfully placed in this genus.
