Hab. Mexico ! 2. 
This insect is only known to me by Herrich-Schaffer’s figure; but I cannot agree 
with Mr. Kirby in considering it a variety of the preceding species. 
ALYPIA. 
Alypia, Hiibner, Verz. bek. Schmett. p. 351; Packard, Proc. Essex Institute, iv. p. 23. 
This genus contains about twenty species, only one of which occurs in our country. 
1. Alypia octomaculata. 
Zygena octomaculata, Fabr. Ent. Syst. i. 1, p. 402. 
Sphine octomaculata, Cram. Pap. Exot. iv. t. 345. f. C*; Hiibner, Samml. exot. Schmett. f. 119,

Alypia quadriguttalis, Hubner, Verz. p. 351. 
Alypia disparata, H. Edwards, Papilio, iv. p. 18°? 
Hab. Nortu America 7,—Mexico, Cordova (Riimel), Jalapa (Hége).—Gutana 2. 
This species appears to be pretty common in Mexico; but as yet I have not seen 
any specimens from any locality further south. I very much doubt the locality given 
by Cramer being correct. . 
Mr. H. Edwards has recently described a species of this genus from Mexico %, and 
this may be represented by our specimens from the State of Vera Cruz. With the 
materials before me I am not in a position to give a positive opinion as to its specific 
value, 
HECATESIA. 
Hecatesia, Boisduval, Monogr. Zygen. p. 11; Walker, Cat. i. p. 54; Westwood, Trans. Linn. Soc. 
ser. 2, 1. p. 199. 
Professor Westwood, in his paper on Castnia and allied groups, places three species 
in this genus, all coming from the Australian region. J have recently received from 
Mr. Champion a fourth species, the neuration of the males being exactly the same as 
in those from Australia. 
1. Hecatesia falcata, sp.n. (Tab. V. figg. 234, 242.) 
Primaries of the males dark brown, marked with paler streaks of the same colour ; two narrow greenish-brown 
lines crossing the wing from the outer side of the vitreous spot on the costal margin to near the anal 
angle; a narrow yellowish line from the base extending to the middle of the wing, which is thickly 
speckled with greyish-white scales; secondaries bright chrome-yellow, very broadly bordered with dark 
brown: head, thorax, and a tuft of hairy scales at the base of the abdomen dark reddish brown, the 
abdomen pale chrome-yellow; antennze brown above, silvery white on the underside; legs yellowish 
brown; the underside of the primaries and secondaries pale yellow, with the outer margins of both wings
