Although this subfamily is a very large one, consisting of about 2,500 forms from all parts of the world, we can list only 63 species from our region. It may be stated generally that these beetles belong to the temperate and subtropical regions, and are most abundantly represented in America. For the purpose of the present work an insect belonging to this subfamily can be recognized in the following way : (1) the antenna front leg. tars us sutural apical angle Fig. 1.—Dorsal view of Chrysolina exant

Wied. tarsi are apparently four-segmented, the basal three segments beiug usually densely set with cushion-like pubescence on the underside, the third segment is expanded laterally into lobes which are not separate, but fused together (except in the genera Atjasta, Ghrysomela *, Phaedon and Plagiodera), and the claw arises from the base of the third segment; (2) the antenuae are separated from each other by the breadth of the front of the head; (3) the anterior coxal cavities are transverse aud oval, not round; (4) these beetles are all phytophagous ; (5) the larvss are free-living. * I. e., Mela&cmia, auctt.; see pp. 17, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Maulik, Samarendra.
