only know from Hubner's figures. The male of C. fidelissima, is 

 smaller than the opposite sex, which it resembles quite closely in or- 

 namentation; the antennae are finely and rather shortly bi-pectinate, 

 the pectinations becoming obsolete at the base and tapering to the tips. 

 The dark blue color of the secondaries reminds one of Ctenucha and 

 Ctenuchidia ; the scarlet costal spots at base of primaries are shared 

 by the following genus.

SPHiEROMACHIA, n. g. 



Head, small, held on a line with the body, not depressed, though 

 but slightly advanced and impromiuent. owing to the very narrow, re- 

 duced, prothoracic pieces. Labial palpi rather long, finely scaled, por- 

 rect, advanced before the "front" which they exceed. Maxillae, short 

 and slight. Legs, weak, unarmed. All the corporal parts are finely 

 and thinly scaled, so as to show the structure of the body crust more 

 plainly than usual. Thorax, globose, rather short, so that, with the 

 small head, it is hardly half the length of the abdomen. Basal abdo- 

 minal segment a little constricted, the lateral glandular pouches are 

 spherical and prominent. Abdomen, cylindrical, long, linear, not 

 wider ( 9 ) than thorax, evenly distended and terminating rather blunt- 

 ly without anal pilosities ; the segments are broader than usual. 



Primaries, broad, large, triangulate; costa arched to apex which is 

 not produced as in Composia, Pericopis, etc., but is blunt, the external 

 margin being extraordinarily straight, very slightly rounded at inter- 

 nal angle, while the internal margin is longer than usual and very 

 straight. In shape the wing thus approaches very nearly a right-an- 

 gled triangle, of which the costa would be the hypotheneuse. The first, 

 second and third m. nervules are thrown off, at nearly equal intervals. 

 at the extremity of the nervure; they are near together at base, and 

 short, the second runs very straightly to external margin, the first and 

 third, on either side of the second, are opposedly arcuate. The discal 

 fold is prolonged beyond the closed discal cell, and is continued on the 

 interspace above first m. nervule. The fourth m. nervule is very wide- 

 ly separated from the third at base, since it springs from the nervure 

 at a point about midway between the base and the point of origin of 

 the third m. nervule; it runs straightly to the margin, but the inter- 

 space, which is very wide at base, is narrowed towards the margin, owing 

 to the arcuation of the third in. nervule and its downward course. .V 

 prominent sub-median fold, parallel with internal margin and eontinu-
