A text-book of entomology, including the anatomy, physiology, embryology and metamorphoses of insects, for use in agricultural and technical schools and colleges as well as by the working entomologist . he found that the large muscles scarcely vary atall, though certain smaller ones are very variable. Lubbock ob-served that certain of the longitudinal muscles in the caterpillar ofDiloba split up into numerous, not less than ten, separate separation of the fibres composing a muscle into separate fas-cicles is carried on to a much greater extent in the larvae of Coleop-tera. Of course in the imago the number of thoracic muscles isgreatly increased, or at least in Dyticus and the wood-feedingLamellicorns, which alone I have examined. In these two groupseach of the larger muscles is represented by at least twenty separatefascicles, which makes it far more difficult to distinguish the ar-rangement of the muscles. The muscles are whitish or colorless and transparent, those in thethorax being yellowish or pale brown ; and of a soft, almost gelatin-ous consistence. In form they are simply flat and thin, straight,band-like, or in rare cases pyramidal, barrel or feather
