ERASTRIAD^. 

 1. Erastria amazonia, n. s. 



Fore wing glossy, ochreous grey, with a dark blotch at the base 

 of the costa, and another towards the apex beyond the second line, 

 which is whitish. Hind wing dark fuscous. Expanse of wings, 

 20 mm. 



The specimen is so much worn that it is impossible to 

 give an exact description. It comes near Erastria (?) 

 hasistigma, Wlk., xv., .1762, from the West Indies, and 

 to an unnamed species from Madagascar.

 2. Isogona inferior, n. s. 



Fore wings sandy brown, dusted with paler atoms, with two 

 white transverse lines ; the first straight before the middle, the 

 second starting from the middle of the costa, at first runs obliquely 

 outwards, forming a small sharp point, and then, slightly sinuous, 

 inwards to the inner margin below the reniform stigma, the base of 

 which it touches ; both stigmata largo and distinct, slightly dai-kor 

 than the ground colour, and finely bordered with paler ; an oblique 

 white streak from the apex nearly unites with the angle of the 

 second line ; three whitish costal dots before the apex ; submarginal 

 line represented by an indistinct series of dark blotches ; a row of 

 brownish lunules along the hind margin, festooned with lighter ; 

 the veins towards the hind margin paler. Hind wings with the 

 reniform stigma, second line, and submarginal row of spots 

 repeated. Head, thorax, and abdomen all sandy brown ; the base 

 of the abdomen bearing a short blackish tuft ; under side dull 

 sandy, unmarked, except by the submarginal row of spots. Ex- 

 panse of wings, 24 mm.

 1874. 



The species is considerably smaller than Isogona 

 continua, Gn., of which Walker's Massava scissa is a 

 synonym, and the coloration is different, but I think 

 there can be no doubt that it is congeneric.
