Show 382 MR. A. G. BUTLER ON HETEROCEROUS [May 1, A second form of case occurs in Mr. Enys's collection; larger, longer, fusiform, of a woolly texture, grey in colouring, with a tendency to darker zones at unequal distances. It is found chiefly on willows, sometimes on Cupressus. Unfortunately the moth does not accompany it in sufficiently good condition for description; it is a species of Clania. Having discovered the type of Morova subfasciata of Walker, I find it to be a large example of Caccecia 1 gallicolens ; the type of the latter description is a dwarfed and extremely dark specimen. Until I have examined really good examples of this species I should not like to hazard another guess at its affinities ; but it certainly does not belong to the Tortricidee. NOCTUITES. Declana floccosa of Walker should, I think, be placed among the Geometrites next to the genus Ligia ; it is congeneric with the Chlenias verrucosa of Felder, which is not a true Chlenias. The form of the wings, slender abdomen, and long antennae, seem to distinguish it from Cnethocampa and allies. LEUCANIID^E. 9. LEUCANIA PROPRIA. Leucania propria, Walker, Lep. Het. ix. p. 111.

After carefully comparing Guenee's description with Walker's type, and with the examples brought to England by Dr. Hector and Mr. Enys, I am perfectly satisfied that the two descriptions represent the same species. Walker's type, which is a female, has not the blackish-grey under surface to the primaries ; nor have specimens obtained by Dr. Hector ; but in two of Mr. Enys's examples this character is well marked. The dots on the primaries and the darker thorax, upon which M . Guene'e lays some stress, are both characteristic of Walker's type, although less strongly indicated than in most individuals of the species. Amphitape crassitibia of Felder is Ipana leptomera of Walker. 12. ALYSIA NULLIFERA. Agrotis nullifera, Walker, Lep. Het. xi. p. 742 (1857). Alysia specifica, Guenee, Ent. Mo. Mag. v. p. 3 (1868).
