The Microptenjfjidce have the largest number of joints, six ; in the Tineidce and Tortricidce the number is very variable ; in the Pyi^alidce four ; in the Noctiddai generally two, but sometimes three ; in the more specialized families one or two ; and in the Papiliones, SpMngidce, and most Gcometridce one*. The cases of the maxillary palpi in the pupse are well developed in the generalized families, the Tineidce, Sesiado', Cossidce, and Limacodida', even when they are aborted in the imago ; in the Pyrcdidce and Zygcenidie they are less conspicuous, and in the more specialized Obtectci' wanting t- The labial palpi are normally well developed and 3-jointed, but aborted or much reduced in the Hepialidce, Psychido', and many Cossidce.; they may be upturned, with the 2nd joint curved, straight and oblique or porrect, or downcurved ; they vary much in form and scaling, the male often having extremely speciahzed develop- ments, but their function beyond that of protecting and cleaning the proboscis is unknown. The antennse are sense-organs composed of an indefinite number of joints and varying much in length and structure; they are * A. Walter, Jena. Zeit. Nat. xyiii. pp. 121-173 (1884); id. Jena.
