NATIONAL MUSEUM Vol. 92 Washington : 1942 No. 3146 DESCEIPTIONS OF THE LARVAE OF SOME WEST INDIAN MELOLONTHINE BEETLES AND A KEY TO THE KNOWN LARVAE OF THE TRIBE ' By Adam G. Boving This paper presents generic descriptions of the mature larvae of the genera Cnemarachis Saylor and Clemora Saylor; a specific description of the genotype Cneinarachis vandinei (Smyth) and taxonomic remarks about the larvae of Cnemarachis neglecta (Blanchard), C. suturalis (Chevrolat), C. dissimilis (Chevrolat), and G. portoricensis (Smyth) ; and a specific description of the larvae of the genotype Clemora smithi (Arrow) and taxonomic remarks about Clemora apicalis (Blanchard) and an undetermined species of Clemora from Cuba. After the descriptions is a synoptic key to the larvae of several exotic species of Melolonthini. The paper has been prepared to follow one by Lawrence W. Saylor ^ dealing with the taxonomy of the same forms in their adult stage. Genus CNEMARACHIS Saylor Plates 18, 19, Figubes 7A, 7B, 13, 14, 19, 20 Anterior marginal part of frons with a transverse series of long setae, about seven on each side; at the middle of frons one fine, long seta on each side; and midway between this seta and the condyle ^ The data herein bearing on the systematic position in the Melolonthini of the North American genus Pliijllophafia are to he incorporated in a comprehensive report on these beetles now being prepared under joint grants from the American Philosophical Society and the National Academy of Sciences.
