Lyeodna Acmon West.-Hew. Abundant at Colorado Springs and in South Park. 



Lyccena Isola Peak. Colorado Springs and South Park; not common. 



Ancyloxypha Hylax Edw. Several specimens were taken along the Ute Pass road. 



Pamphila Eohomok Harr. Taken in Engelmann's Caiion and the Ute Pass. 



Patnphila Comma Linn. This species in the forms Manitoba and Nevada was 

 obtained in the South Park in considerable numbers. 



Pamphila Uncas Mdw. Common about Colorado Springs and in the South Park. 



Pamphila Snawi Edw. This was the only new " diurnal " taken by our expedi- 

 tion. It was named and described by Mr. W. H. Edwards. The following is the 

 description as given by him in the Canadian Entomologist, Vol. IX, pp. 29, 30: 



" Male— expands 1.1 inch. ; size and shape of Leonardus, the hind wings some- 

 what less prolonged anteriorly. 



" Upper side of both wings light glossy brown ; primaries have rive translucent 

 spots, namely, one sub-apical, oblong, narrow, cut into three equal parts by the sub- 

 costal nervules; three discal, the first being at the top of the upper median inter- 

 space, small, semi-oval ; the next large, irregularly quadrate, crossing the next lower 

 interspace, and the third on sub-median interspace, less transparent, more yellow, in 

 one example clearly defined, sub-triangular, in the other diftuse; these three spots 

 forming an oblique line back of and below the cell ; the fifth spot is at the outer end 

 of the cell, a narrow transverse bar; the stigma long, narrow, a little sinuous on the 

 middle, black, edged in the middle by rough dark brown scales on either side. 



" Secondaries have an abbreviated discal row of indistinct, small yellow spots, 

 placed nearly parallel to the hind margin, and restricted to the discoidal and median 

 interspaces, or very nearly so ; in the middle of the cell a small yellowish spot, 

 almost obsolete; fringes cinereous, those of secondaries lighter than the others. 



" Under side of both wings brown with a russet tint; primaries somewhat fuscous 

 near base, m and below cell, and pale yellow in the sub-median interspace ; the spots 

 repeated except the lower of the three, which is lost in the color of the interspace 

 just mentioned; secondaries have the discal spots more distinct, yellowish, and 

 there appear faint traces of obsolete spots which w^ould complete the series to 

 costal margin ; the cellular spot small, distinct, rounded. 



" Body above brown, below the thorax gray-brown, above the collar yellow-tipped; 

 abdomen yellow-gray ; legs brown ; palpi sordid white, gray at tips ; antennie fuscous 

 above, grayish below; club fuscous for a narrow space on upper side, elsewhere russet. 



" From 2 $, sent me by Prof. F. H. Snow, and taken by him in Colorado, at Ute 

 Pass, while in charge of the Kansas University Scientific Expedition, 1876. No 

 others were taken, as I am informed. 



" The species is near Leonardus, from which it differs in not having the basal area 

 of primaries fulvous, in not having two spots near hind margin in the discoidal 

 interspace, in having the spots translucent instead of fulvous, and in having a dis- 

 tinct spot at end of cell ; the stigma of Leonardus dilfers considerably also, being 

 heavier, somewhat curved, and especially broken in on the lower median nervule, 

 of which the posterior part is thrown back of the line of the remainder; the spots 

 on <lisk of secondaries in Leonardus are placed as in the present species, but are 

 larger, and either quite distinct or largely diffuse, examples varying. The under 

 side of Leonardus is more red (cinnamon-brown), and the series of spots on second- 

 aries is complete and distinct, as is also the cellular spot. In these wings the 

 resemblance between the two species is closer than elsewhere. They form a very 

 interesting group." 



Mr. H. K. Morrison, in 1877, found this species quite abundantly in Southern 

 Colorado.
