This very elegaut and distinct little species resembles A. virgo some- 

 what in the coloration and ornamentation of the posterior wings, as also 

 A. lyliijUra in the disposition of the terminal bands on anterior pair, 

 while it is abundantly distinct from either. 



I dedicate this species to Charles A. Blake, Esq.. of Philadelphia, 

 the Entomologist, and my kind friend. 



LAGOA. Harris. 

 Lagoa cretata, nov. sp.

 Posterior wings and fringes similar. Thorax clothed with long pure 

 white hair ; head clear pale lemon-yellow between the antennae, black- 

 ish beneath ; antenna; pale fulvous brown, stem white at base, shorter 

 and less deeply pectinate than in the allied species; abdomen white, 

 marked with fulvous on the segments as in L. crittjKita ; dorsal hairs 

 white, except a large pale lemon-yellow tuft at base. S . Exp. 1.20

 Readily distinguished from the already described species of the genus 

 by the pure white smooth immaculate anterior wings, with straighter 

 costal margin. The glossy wings of this species recall those of the ge- 

 nus Porthesia, with, however, ditt'ering scjuammation, showing the po- 

 sition of Lagoa among the Liparidtc. In the event of more material 

 rendering a generic separation of the present species necessary, I pro- 

 pose the name of Ulosota for the new genus.

Anterior wings narrow, cinereous, with a uniform, more or less de- 

 termined, reddish shade; ordinary lines dark, distinct but interrupted. 

 Basal half-line blackish, distinct, straight; transverse anterior blackish, 

 geminate, nearly straight, forming three even curves. Ordinary spots 

 large, distinct, concolorous with the rest of the wing, annulated with a
