156 THE CANADIAN ENTOMOLOGIST. 



Ccenonymp/ia {Erebia) Haydenii — ? . This differs markedly 

 from the $ in being entirely different in colour. Males are dark 

 smoky-brown, and the females are nearly same colour as Coen. inoniata but 

 not so reddish. This species was found in numbers by Prof. Snyder at 

 Beaver Canon, Idaho, last of July and first part of August, 1895. 



Thecla da/non, n. var. discoidalis. — Differs from typical form in having 

 central area "of both wings light greenish-yellow. Round Mountain, 

 Blanco Co., Texas, February loth and August i6th. 



Pieris ochsenhehneri, Staudinger (Stett. Ent., Zeit., 1886, p. 199). 

 This specie^ was described by Dr. Staudinger from Central Asia, and is 

 beautifully figured in " Memoires sur les Lepidopteres " by N. M. 

 Romanoff, 4, 220, pi. 14, f. i a, b, 1890. Through the generosity of Dr. 

 Herman Strecker, of Reading, Penna., I received two males and a female 

 of a Pieris unknown to me from Mt. Wrangel, Alaska. They prove to be 

 the above-mentioned species. As Romanoff's work may not be accessible 

 to many, I append the following description : — 



$. — Expands \'^ inch. Upper side: Superiors white with costa 

 blackish-gray ; apical costa, apical portion of wing and upper part 

 of outer margin blackish. There is a round black spot in the 

 space between last costal and first discoidal nervure. Neuration 

 shows faintly gray scales. Bars of wing black. Inferiors white with 

 only one spot and that on outer third of costa, round, black. Base 

 of wings black ; there is a very narrow, dark, submarginal line to both 

 superiors and inferiors. Under side : Superiors much as above except 

 that apices of wings are yellowish, and there is an additional spot 

 (not always well defined) below the third discoidal nervure. Inferiors 

 have mixed yellow and gray spots as in Pieris napi bryonice. The female 

 differs from tne male in having the veins rather heavily marked with dark 

 scales, as are also the apices of superiors and bases of all four wings. It 

 has an additional dark spot on , superiors. Below the veins are not as 

 heavily marked and the ground colour of wings is white instead of 

 yellow. 



Systasea pulverulenta^ Feld. — I have received a specimen of this 

 species from Prof. T. D. A. Cockerell, who sends the following particulars : 

 " Caught April 22nd at Mesilla, New Mexico, on flowers q>{ Bisadella 

 Wislizenii. It is different from any Hesperid I have caught here. When 

 I saw it I thought it was a moth near to Drasteria"
