23t) THE CANAIMAN ENTOMOLOGIST. 



Hydriomenas ; beyond this line is a clear outer margin with dots at the 

 ends of the veins at base of fringe, which is quite long and brownish, with 

 a line running through. Hind wings brownish, showing traces of two 

 irregular dark lines, pale between, fringe whitish, with intervenular dots. 

 Tip of abdomen tufted, as are all the Hydriomenas. Beneath, fore wings 

 pale ash-gray, showing faintly the lines above, the two near outer border 

 being plainest, and the apical streak. Hind wings same colour as fore 

 wings, with only one of the black lines showing, that being the inner one, 

 which makes quite a dip. This species can be readily distinguished by 

 the long palpi and straight mesial bands, which are peculiar for this group. 

 I take pleasure ill naming this geometer after Dr. Barnes, who has done 

 so much to increase our knowledge of the western species. 



Types, 3 $ 's, two from Dr. Barnes. Huachuca Mts., Ariz, and one 

 from Mr. (irossbeck, Arizona, and in their collections. 



Hydriomena Cochiseata, n. sp. — Expanse, 31-33 mm.; palpi short, 

 about 1 mm. in length, brownish, white-tipped ; wings full and rounded, 

 more like Mesoleuca; front of head whitish ; thorax and abdomen gray. 

 Fore wings dark gray, with a reddish tinge in one specimen. Basal band 

 smoke coloured, then a light space; median space made up of the usual 

 three bands, the first basally irregular and bent outwards, particularly on 

 median vein, thence to inner margin in two scallops ; the second band is 

 hardly distinguishable, but is broad and irregular, as the median band has 

 no clear space between the lines, but is suffused with smoke-colour; the 

 outer band is also very irregular, starting from a black patch on costa, 

 whence it runs to inner margin, meeting middle line and fusing with it to 

 foim a Y, as in furcata = sordidata of Europe ; in some cases the mesial 

 space is narrow and irregular, being not over 4 mm. at widest part, which 

 is rather striking in this group ; this band is in one example white, and in 

 the second suffused with gray ; the outer line bordering mesial space starts 

 very irregularly near costa in a series of notches, and is (mite wide till 4 

 mm. below costa, then it is an irregular black hair line to inner margin. 

 From this line to outer margin both specimens are suffused with dark gray ; 

 a second irregular line is scarcely visible near outer border, there being a 

 reddish shading on either side. Marginal dots and moderately long brown 

 fringe. Hind wings brown, with two characteristic pale lines. Beneath, 

 pale gray on fore wings, with the white mesial space showing plainly and 

 black outer line. Hind wings same colour as fore wings, and with inner 

 line showing.
