 Types, Coll. Barnes. 



Hampson defines the genus Bryomima as having the thorax 

 "clothed with hair and a few scales mixed," places, however, in the 

 genns pulvcrulcnia Sm. which has the thoracic clothing composed of 

 feathery scales. As our new species agrees generically with pidvcr- 

 ulciita we place it under Bryomima. This species is related to a form 

 from South California which we take to be fallax Hampson and which 

 has possibly been partially (the dull form) redescribed by Smith under 

 the name Antitype tiiittara; it is paler than this species with the dark 

 and light areas much more contrasted; it is probably but a local race 

 of the California species, but as we are uncertain about the correct 

 name for this we describe the Arizona form as a distinct species. 



Trachea (Hadena) aruora sp. nov. (Plate II, tig. 12.) 



Primaries deep purplish-brown, smooth, maculation fairly distinct ; basal 

 line black, geminate, extending half across wing, connected with base of wing 

 by a line black dash, filled with pale purplish scaling ; t. a. hne evenly crenulate 

 in the interspaces, geminate, black, outwardly oblique, filled with pale purplish ; 

 orbicular slightly paler than the ground color with dark centra! shade, outlined 

 in black, small, oval; claviform outlined in black; reniform large, upright, 

 margined on inner side with black ; defined outwardly by three white dots, the 

 central one being the largest, filled with dark scaling and with an incomplete 

 pale purplish annukis ; t. p. line black, geminate, preceded by slight whitish scal- 

 ing on costa. rather squarely exserted around cell, rigidly oblique in lower half, 

 filled with pale purplish and followed by minute black streaks and white dots 

 on the veins, opposite claviform shaded inwardly with black; subterminal space 

 even dark purple-brown, slightly sprinkled with whitish ; terminal space darker, 

 scaled with blue; s. t. line pale, waved, somewhat bisinuate. not distinct; a ter- 

 minal series of black dots ; fringes dark with pale points at termination of 

 veins ; secondaries smoky-brown, fringes with an ochreous basal line. Beneath 

 smoky, slightly tinged with pink, with small discal dots and indistinct post-
