ble ; all that can be said of them is, that both are of good size, and as far as can 

 be made out, of the normal form. Secondaries white in both sexes, immaculate. 

 Beneath whitish, primaries with an incomplete outer line ; secondaries with a 

 discal dot. Expands 30-34 mm.; 1.20-1.36 inches.

Two males and one female are before me, all of them in fair con- 

 dition. The species is an ally of ccenis, but is smaller, and more 

 vaguely marked, and has the secondaries white in both sexes, resem- 

 bling, in thiri particular, mcereiis, to which it has a marked habital 

 resemblance as well. The median shade, vague as it is, is yet suffi- 

 ciently obvious to require the reference of the sj:)ecies to the messoria 

 group of the genus. In this group it is impossible to confound it 

 with anything known to me. 



C'ariieades collo<*ata n. sp. (PI. iii, fig. 5) — Ground color a rather dark 

 fuscous brown, with very fine black powderings. Head coucolorous, collar with 

 a broad black transverse line, patagise with a black submargin. Primaries with 

 all the transverse markings obsolete, the veins all black marked. A black basal 

 dash, at the end of which is the narrow, loop-like claviform, outlined in black, 

 with a concolorous centre. The cell is black-filled before and around the ordi- 

 nary spots, which are united, decanter-shaped, inwardly pale annulate, the centre 

 concolorous with the ground. The terminal space is somewhat darker than the 

 remainder of the wing, cut with the paler shade of the s. t. space, most obviously 

 on veins 3 and 4, and 6 and 7. These streaks are not of a character to obscure 

 the reference of the species to the pitychrous series of species, but are yet obvi- 

 ous. A lunulate terminal line, followed by a pale line at the base of the fringes. 

 Secondaries in the male white, with a dusky terminal line, in the female with a 

 faint smoky tinge, becoming more marked outwardly. Beneath white, powdery 

 along the costa and outer margin, darker in the jirimaries. Expands 31-33 mm. ; 

 1.24-1.32 inches.

This is an ally of hollemani and airistriga, differing from each of 

 them in the dark, dull and rather even color of the primaries, the 

 costa barely paler in some of the specimens that I have seen, and 

 not at all in others. The secondaries on the contrary are white, in 

 strong contrast to the dusky shade in hoUemani, and the broadly 

 margined form of atrktrlga. It also bears a resemblance to insertans, 

 of the -i-deidata series of the genus ; but differs from that in the 

 ground color, and in lacking the prominent pale streaks of the series. 

 Male and female are before me, and I am afraid that I have on pre- 

 vious occasions mistaken it for a form of hoUemani where only one 

 sex was in mv hands.
