FAMILY DALCERIDAE. 

 Paracraga amianta, new species. (Fig. 42, No. 22.) 



Fore wing ocher yellow, the costa at apex and outer margin 

 narrowly white. A shining silvery area in the center of the 

 wing, from above vein 1 to the lower part of the cell, a brown 

 line starts from the origin of vein 2, nearly attains the costa and 

 then returns across the discal venules to terminate at vein 1 

 above the expanded anal angle, inclosing an irregular rusty 

 brown marking in the cell. A minute black dot on vein 1 at 

 its basal third ; a terminal row of similar dots at the ends of the 

 veins, distinct only at veins 2-4 and subapically. Hind wing 

 white with an ocherous wash, except along the margin. Ex- 

 panse, 24 mm. 



One $ , Hoorie, British Guiana (C. W. Beebe). 



Type.— No. 12641, U. S. National Museum. 



Allied to Paracraga innocens Schaus, but possessing a dis- 

 cal silvery area, while the brown line does not attain the costa. 

 Minacragides, new genus. 



Fore wings without accessory cell; vein 11 stalked with 9, 

 10 absent ; 6 arising above the discal vein, 7 and 8 coincident. 



Minacragides arnacis, new species. (Fig. 42, No. 23.)

 One $ , Hoorie, British Guiana (C. W. Beebe) . 

 Type. — No. 12642, U. S. National Museum. 

 The wings are partly denuded of scales, but I can discover 

 no traces of any markings. 



Family MEGALOPYGIDAE. 

 Trosia nigripes, new species. (Fig. 42, No, 24.) 



Head white, the front below and the orbits black; antennae 

 with the shaft white-scaled, the pectinations pale straw-color. 

 Body and wings above entirely pure white, the fore wing crossed 

 by irregular bands of more shining scales. Wings and body 

 white beneath, the fore legs, tibiae and tarsi of mid legs, tarsi 

 of hind legs strongly marked with black without. Expanse 

 42 mm. 



One $ , Hoorie, British Guiana (C. W. Beebe). 



Type. — No. 12658, U. S. National Museum. 



I thought at first to identify this species with Phalsena 

 Bombyx nivea Stoll, which Baker placed doubtfully in Carama,
