in those from Panama and South America it is pale yellow, in some examples almost

ANISOTHRIX. 
Anisothrix, Ragonot, Ann. Soc. Ent. Fr. 1890, p. 478 (44). 
Mons. Ragonot includes a single species in this genus: it is from Chanchamayo *, 
and an insect sent us by Mr. Forrer from N.W. Mexico seems to belong to the 
same species. 
1. Anisothrix adustalis.

Hab. Mexico, Presidio de Mazatlan (Forrer).—Pzrvu, Chanchamayo !. 
One specimen in poor condition, very similar to Mons. Ragonot’s figure. 
| EPISEMNIA. 
Episemnia, Ragonot, Ann. Soc. Ent. Fr. 1890, p. 481 (47). 
Two species are referred to this genus by Mons. Ragonot—Z. subauritalis, Ragon., | 
and &. josialis (Feld. & Rogenh.), both from Tropical South America, one of which 
extends northward to Mexico; a third is now added.

2. Episemnia ligatalis, sp.n. (Tab. LIX. fig. 11.) 
Primaries black, with a wide yellow band extending down the middle from the base to the outer margin, the 
fringe black; secondaries black, with a wide contral yellow band, which extends from the base to the 
outer margin, the fringe from the apex to the anal angle black, the inner margin and anal angle yellow ;

thorax, abdomen above, and legs black. Expanse 1} inch.

MAPETA. 
Mapeta, Walker, Cat. xxvii. p. 17 (March, 1863) ; Ragonot, Ann. Soc. Ent. Fr. 1891, p. 646 (260). 
Homalochroa, Lederer, Wien. ent. Monats. vii. p. 832 (October, 1863). 
Walker placed this genus amongst the Crambites in his family Galleride. Lederer 
* The locality is stated to be in “Amérique centrale”; but this is evidently a mistake.
