review, the ground that Hubner's genus Megalopyge was a mixed genus, 

 being proposed for two species, lanata and nuda, and that there was 

 no proof that these two species were congeneric. In the absence of such 

 proof, it was not correct for Berg to designate lanata (and its structural 

 aUies) as either the type of or typical of Megalopyge. Under these 

 circumstances, I preferred Harris's term Lagoa as a proper restriction of 

 Hubner's genus for the type to which pyxidifera, opercularis and crispata 

 belong. I did not know then, what seems to be the fact, that Lagoa was 

 preoccupied and must be wholly rejected on this score. But then Pimela, 

 Clem., i860, for the same type must be considered as the next available 

 term for a restriction of Megalopyge. The matter stands thus : If lanata 

 and iiuda are congeneric, then Pimela falls as a synonym of Hubner's 

 genus. If these two are 7iot congeneric, then Clemens's term must be used 

 for lanata and our North American species, as the first restriction of 

 Hubner's genus, and Megalopyge must be left to the type nuda, a species 

 quite unknown to me. As to this and related matters, I think I can refer 

 the student to the paper in "Papilio," above cited, in which I drew the 

 attention of American Lepidopterists quite fully to Berg's valuable 

 writings,

" The Classification of the Lepidoptera." by Vernon L. Kellogg, American 

 Naturalist, Vol. XXIX., pp. 248-257, plate XVII. (March, 1895). 

 Mr. Kellogg reviews Prof Comstock's classification of the Lepidop- 

 tera especially in regard to the establishment of the sub-orders Jugatje 

 and Frenati^ (Evolution and Taxonomy), and shows how his own 

 researches on the wing scales corroborate this division. He adds nothing 

 essential to his former results in this direction (Kansas Univ. Quarterly, 

 III., 45-S9, 1894), and so far it appears that the wing scales do not afford 

 a basis for the subdivision of the Frenatae. The new part of the present 

 article consists of a consideration of the mode of specialization of the 

 meso- and meta-thoracic segments, as effected by a cephalization af the 

 powers of flight. The Jugata are found to be in a generalized condition 

 in this respect, but apparently not more so than certain Tineidas ; there- 

 fore, the result of this investigation is not a convincing support of Prof 

 Comstock's sub-orders, though it does show that the Hepialidse belong low 

 in the scale, as they are placed in Dr. Chapman's pupal classification. It 

 is another argument against the old group of Bombyces.
