inner margin sinnons. Hindwing with costa sinnoiis, and trnncate npex ; jirominent 

 teeth at veins i and 7, a slighter tooth at vein 6 ; snbmedian interval on hindwing 

 with discoloured scaling, the inner margin slightly convolute ; palpi quite short. 

 In coloration strongly resembling Saccoploca, but in shape of wing and neuration 

 like Epiplema. 



4. Gathynia dilacerata. 



Erosia dilacerata Guen., Phal. ii. p. .S7. (J J . 



This species must be referred to the genns Gathynia. I have lately seen a ? 

 from Huatnxco, Vera Crnz, the structure of which is conclusive. Guen6e gave 

 10 mm. as the expanse of the cJ, adding that the ? was somewhat larger. The 

 present example expands 26 mm. 



Lophopygia gen. nov. 



$ . Foretvimi : with costa straight, curved only at base and before apex ;

 margin sinuous.
