in size and maculation, but has the basal area tinged with white whereas 

 in the type it is unicolorous brown ; we imagine this is a variable feature 

 as in quernaria A. & S. ; we figure the specimen as typifying our con- 

 ception of mexicanaria. For the species usually identified as mexi- 

 canaria a name is needed ; we describe it as follows : 



Phaeoura perfidaria sp. nov. (PI. XXVI, Figs. 4, 5). 



S . Antennae strongly bipectinate, more so than in mexicanaria; head 

 and thorax mixed gray and brown, the latter crossed by two black bands as in 

 cristifera Hist, and with black metathoracic tuft; primaries light olivaceous 

 brown, shaded with whitish subterminally ; t. a. line sharp, black, bent outward 

 below costa and forming a blunt tooth in the cell, a slight inward angle on 

 cubital vein, followed by a bulge in the fold after which the line is oblique to 

 inner margin near base ; the basal area contains some black sprinkling tending 

 to form basal dashes in and below the cell ; median area even brown with a 

 large black discal ringlet; a faint median line curving around discal ringlet and 

 running very close to t. p. line in lower half of wing; t. p. line black, lightly 

 concave from costa to vein 4, then parallel to outer margin to vein 5, forming 

 slight teeth on both veins, then strongly incurved to vein 1 where it forms a 

 sharp angle and finally inwardly oblique to inner margin ; beyond the t. p. line 

 is whitish shading, especially in the concavities ; faint traces of a whitish s. t. 

 line parallel to outer margin preceded by a brownish shade and followed by 

 darker shading; secondaries pale, heavily sprinkled and peppered with brown, 

 with a large discal ringlet and a black t. p. line, angled and toothed on veins 3 

 and 4 ; terminal area much as on primaries ; dark terminal line on both wings. 

 Beneath whitish, slightly peppered with smoky and with the maculation of upper 

 side faintly visible. 



5 . Larger than $ , with a prominent bright brown patch on thorax, and 

 considerable bright brown shading on primaries basally, subterminally and along 

 costa and inner margin of median area; beneath more heavily peppered than 

 the $ . Expanse $ 48 mm., 2 56 mm.

Phaeoura triaria sp. nov. (PL XXVI, Fig. 3). 



Thorax deep brownish ; primaries with the color and maculation essentially 

 as in the preceding species but the lines instead of being clear cut are diffuse 

 and indistinct ; the basal and median areas are covered with rather rough smoky 

 scaling and the discal ringlet is a patch of slighly raised dark scales with a faint 

 whitish center; the secondaries are heavily peppered with smoky brown and the 

 maculation is of the same indistinct and rough type as on primaries. Beneath 

 more heavily sprinkled than in perfidaria. Expanse 50 mm. 



Habitat : Redington, Ariz. 1 $ . Type, Coll. Barnes. 



The peculiar rough nature of the squammation and the diffuse 

 type of maculation, besides the greater size, warrant the supposition
