AMERICAN LEPIDOPTERA. 329 



niiiial band, which is divided into spots by the bhick nervules, being 

 much narrower on either wing and coming to a point superiorly on the 

 primaries. The discal spot of the primaries is smaller in A. maceul- 

 lochii than in A. lorquinii, and on the under surface the basal patch 

 is larger. On the upper surface of the secondaries, the sub-terminal 

 band is composed of five spots in Kirby's species, while in A. lorquinii, 

 where it tapers inferiorly, it contains but four. On the under surface, 

 the white basal patch in Kirby's species is more extended, and the 

 sub-terminal band receives one or two accessory spots inferiorly. Fi- 

 nally, the maculations of the secondaries are white in A. maccullochii 

 and pale yellow in A. lorquinii. 



8. Alypia mariposa. n. sp. (Plate C, fio-. 40, 9.) 



9 . — Black. The eyes, behind, are prominently margined with pale 

 yellow scales, elsewhere the legs, body parts and appendages are en- 

 tirely black. Wings elongate, ample, black. Costal edge of primaries 

 sub-sinuate, being medially depressed and accuminate at apices. An 

 elongate, sub-triangular, pale yellow spot at base. A rounded discal 

 spot and two similarly colored, angular, sub-terminal spots: the first 

 situate superiorly sub-costally beyond the disc; the second on the in- 

 terspace above nervule 2 (H-S.), beneath, but widely separate from' the 

 first, and differing from it in shape. Fringes, black, except at the 

 apices where they are white. Secondaries with a series of extra dis- 

 cal, pale yellow spots, of which the first is larger and rounded, the 

 second and third, situate inferiorly towards the internal margin, are 

 approximate, smaller and obsoletely separated. Fringes black, vt^hite 

 at the apices. Beneath, as above; on the primaries the basal spi)t is 

 divided by dark scales clothing the median nervure ; on the second- 

 aries the inferior extra-discal spots are obsolete, being represented by 

 a few powdery scales ; the maculations on both wings are paler, nearly 

 white. On their upper surface, the primaries show sparse and scat- 

 tered pale scales along internal margin. On the secondaries there is 

 a faint indication of a discal spot, more prominent beneath. In this 

 species the wings show a disposition to become dusted with pale scales 

 on either surface.

In this species the ample and elongate wings, the number of the 

 alar spots and the black legs, afford ready distinguishing characters. 

 The antennae are defective in our specimen.
