can species lituralis (1. c. Figs. 19, 20) and this portion of the publi- 

 cation was probably issued considerably before 1818; as this is a very 

 clear case of the usage of a generic term along with a single specific 

 name, we hold that the genus was originally monobasic with lituralis 

 Hbn. as type of the genus, Hubner's later action in the Verzeichniss 

 being merely an extension of the generic conception to include other 

 species which he considered congeneric. 



Our usual conception of the genus as given in Smith's revision of 

 Deltoid Moths (1895, Bull. 48 U. S. Nat. Mus.) and as followed 

 by Dyar and Schaus must be changed. Epizeuxis Hbn. will supplant 

 Zanclognatha Led. as used in our lists and for the genus to which 

 the name Epizeuxis has been usually attached we must seek a new 

 name; Helia Gn. cannot be used as it is preoccupied by Hclia Hbn. 

 (Verz., 259) and Grote's term Pseudaglossa (Buff. Bull., II, 47) we 

 believe will fall to Camptylochila Steph. (1834, 111. Brit. Ent. Haust., 

 IV, p. 21) proposed for two species, nndulalis and bistrigalis, presum- 

 ably British, but which Stephens later (1850, Cat. Lep. Brit. Mus., p. 

 303) lists as North American; judging by Wood's figures of both 

 species (Ind. Ent., PI. 27, Figs. 77^ and 774) and Stephens" figure 

 of the latter species (1. c. PI. 2)Z, Fig. 3) we believe that undulalis is 

 aemula Hbn. and bistrigalis will fall to lubricalis Geyer. With un- 

 dulalis {aemula) as type, the genus Camptylochila can be employed 

 in precisely the same sense, therefore, as Epizcuxis as used by Schaus 

 and for those who desire fine distinctions Grote's Pseudaglossa may 

 still be used for the lubricalis group as has been done by Schaus (1. c. 

 p. 360) who separates the two in his key on antennal differences. 

 We are indebted to Sir Geo. Hampson for first calling our attention 

 to Stephens' generic name. In going over the species of this genus we 

 have come across a group of four closely allied species for which 

 apparently only two names are available ; of these four the first named 

 and best known species is rotundalis Wlk. {borealis Sm.) (PI. XVIII. 

 Fig. 10) a deep purple-brown species with indistinct maculation ; in 

 well-marked specimens the lines are rather broad, blackish, the t. a. 

 upright and the t. p. only slightly bent inward at costa and practically 

 parallel to outer margin ; the renif orm and orbicular are never prom- 

 inent and the under side of secondaries is pale smoky with obscure 

 discal spot and dark postmedian and subterminal lines. 



A second species is forbesi Frch. (1895, Bull. 111. Sta. Lab. N. 

 Hist., IV, 8) of which merrickalis Sm. must be made a synonym;
