THE CANADIAN ENTOMOLOGIST. 231 



Types, 2 $'s, Palmerlee, Cochise Co, Arizona, from Mr. Broadwell's 

 collection. 



Hydriomena Glenwoodata, n. sp. — Expanse, 25 mm ; palpi rather 

 long and slender, blackish ; front of head grayish ; thorax and abdomen 

 gray. Fore wings light ash-gray, with slightly greenish tinge of a more or 

 less mottled appearance. Line at base of wing hardly discernible, first 

 line of the mesial band bent outwards very strongly between median vein 

 and costa, below it runs almost straight from vein to inner margin ; second 

 line fairly wide, rather irregular in course, appearing in three blotches on 

 costa, median vein and inner margin ; outer line, starts outward from 

 costa, and then in a peculiar S-like curve, which in one specimen is rather 

 broad to inner margin, where it forms a black patch, a characteristic 

 marking of a good many of this group. The mesial space is pale and 

 rather suffused wjth dark gray, discal spots easily distinguished, linear. 

 Line bordering mesial space externally starts as black patch on costa, then 

 a fine line discernible as dots on veins to inner margin. Marginal band 

 irregular and smoke-coloured, rather broad, exterior margin clear, except 

 for dots at end of veins at base of fringe. Apical streak appears as a spot ; 

 fringe light ash and short. Hind wings dark ash, two pale outer lines 

 hardly visible, discal dot, unless looked for especially, is so minute as to 

 escape detection. Beneath the fore wings are quite a dark smoke colour, 

 with the linear discal dot showing faintly. The submarginal line shows 

 quite plainly from costa to median vein, and is shaded lighter externally, 

 the genera] course being a low curve. Hind wings lighter than fore wings, 

 discal spot hardly visible, faint outer line showing. The long slender 

 palpi and the peculiar double curve of the outer line of mesial band will 

 serve to distinguish it from autumnalis or other forms.

Hydriomena Chiricahnata, n. sp. — Expanse, 25-28 mm.; palpi 

 moderate, 1 mm. in length; front of head dark gray, same colour as palpi. 

 Fore wings rather long and pointed, of a reddish ash colour in the mesial 

 space and greenish on mesial band and outer margin (basal band, if any, 

 does not show) ; first line curved outward from costa to inner margin ; 

 second line hardly visible, narrow and rather zigzag in its course ; third 

 line of mesial band bends quite sharply inward from costa almost to
