fully or partially by dark lines whilst our five Hymers specimens show 

 no trace of this; the orange of the upper side is very bright and the 

 purple-brown of the under side very deep. We propose the above 

 name for this Hymers race and have marked as type the $ specimen 

 figured as mentioned. Paratypes are 3 3,1$ all from Hymers 

 (Apr. 24-30, May 1-7). 



Type and paratypes in Coll. Barnes. 



Trichodesia albovittata tenuifasciata var. nov. (PI. XXII, Fig. 7). 



Four specimens before us from Spirit Lake, Idaho have the white 

 band of primaries much narrower (1 mm. in width) than in the typical 

 Eastern forms (PI. XXII, Fig. 8); the secondaries are immaculate 

 black and the fringes on underside seem constantly dark with the ex- 

 ception of the apex of both wings and the termen of primaries whilst 

 in the Eastern race the secondaries usually (although not always so) 

 are checkered with white. We have similar specimens from Glacier 

 Nat. Park, Montana, whilst specimens from Wellington, B. C. appear 

 to agree with the Eastern form. Apparently we are dealing with a race 

 inhabiting the Northwestern States for which we propose the above 

 name. 



$ Type and 3 $ Paratypes from Spirit Lake, Idaho (July 1-7) 

 in Coll. Barnes. 



Triphosa bipectinata sp. nov. (PI. XIX, Fig. 6). 



Palpi upturned to about level of front ; antennae in $ bipectinate ; thorax 

 and primaries light shiny gray-brown, the latter crossed by numerous darker 

 undulate lines ; basal and median areas darker than the remainder of wing ; post- 

 median area with the cross lines merely marked by dots and slight arrow marks 

 on the veins. Secondaries rather uniform smoky with faint traces of the lines 

 of primaries; outer margin of both wings faintly crenulate and marked by dots 

 on each side of the veins. Beneath smoky with scarcely a trace of the macula- 

 tion of the upper side showing through. Expanse 35 mm. 



Habitat: Palmerlee, Ariz. 2 $. Types, Coll. Barnes. 



Our Paratype shows the median area considerably darker than in 

 the Holotype, forming a dark band across an otherwise immaculate 

 brown wing ; the species, which is rather difficult to describe, should be 

 readily recognizable from the figure ; apparently it is closely related to 

 Monotaxis semipectinata Hist., differing however in the longer up- 

 turned palpi and in the bipectinate $ antennae. We are rather doubt- 

 ful as to the correct generic reference, but the biangulate nature of the 

 discal veins on secondaries and the general type of maculation would
