^48 THK CANADIAN ENTOMOUKJIST. 



Previa, n. gen. (Type P. argentata.) 



Proboscis moderately strong ; palpi upturned to just beyond front, 

 with long hairs beneath ; front smooth, rounded, densely clothed with 

 smooth short hairs ; eyes prominent, rounded ; antennae of both sexes 

 finely ciliate, more prominently so in male sex ; fore tibia short, thickly 

 haired, with long curved claw at extremity ; head and thorax clothed with 

 long rough hair, untufted ; abdomen smooth. Fore wing narrow, broad 

 at base, outer margin rounded; vein R, from middle of cell, areole present, 

 Rj and R, stalked, togetljcr with R^ from apex of areole, vein M, from 

 upper end of ceil, veins M, and M, and Cu from near angle of cell. Hind 

 wings with veins R and M, slightly stalked, M, and Cu from angle of cell. 



This genus is closely allied to Eutolype Grt., and Co/>t/>anolis Grt., 

 differs, however, from both in the stronger proboscis, the lack of the 

 corneous process of fore tibia, and in antenna,* of male being ciliate and 

 not pectinate. In thoracic vesiiture it more nearly approaches Copi- 

 panolis, whilst the shape of wing resembles that of Eutolype. 



Previa argentata, n. sp. 



^ . — Palpi gray, with black hairs ; front yellowish-white ; vertex, 

 thorax and patagia largely gray, with black stripes ; abdomen snioky 

 brown ; legs gray, with patches of long black hairs at base. Primaries 

 smoky-brown, darkest in central portion of wing, and shaded along costa

 oblong, black, thinly outlined with silvery-while; reniform large, upright, 

 black, edged with white and with a few pale scales in centre. From its

 margin of which is deeply notched; from the upper tooth a blackish shade 

 extends to outer margin, continued towards apex as a series of decreasing 

 black s|)ols ; claviform silvery-white, edged with black, and preceded by a 

 thick black basal dash, through which the anal vein is traceable as a thin 

 white line. Outer margin occupied by a series of irregular white i)atches, 

 not prominent at apex, but more or less confluent towards anal angle ; 

 veins scaled with black towards extremity , frmges smoky-brown, inter- 

 rupted with white opposite veins. Secondaries whitish ; veins distinctly 

 marked in brown.
