XLIX.—The melolonthine beetles of Ceylon

4~2 1Kr.G. J. Arrow on t~e Apogonia (" Plectris ") solids, Walk.=A.ludificans, Brenske.This was deselfibed by Brenske as a variety of A. comosa, Karsch, but I believe it to be specifically distinct.It is invariably larger, with the head and pronotum less closely punctured and the front tibia less produced at the end. A. comosa, Karsch.I con~ider it doubtful whether this really occurs on the mainland of India as maintained by Brenske. A. lateralis, sp.n. ,4 lurida, Karsch.A. nana, Walk.The type is unique and in bad condition.A. cequabilis, Karseh.A. gracdlis, sp.n. A. coriaeea, War. A. nietneri, Kolbe. A.
