color, those on secondaries largest and sometimes having black centres, on pri- 

 maries minute, except the two at the ends of the row ; in the disc of secondaries, 

 a white G, varying in form, but usually thick and angular with each end sharp 

 and barbed ; body above black, covered with greenish hairs ; below, brown 

 grey; antennre dark brown above, whitish below; club black with a yellow tip. 



Female. Underside more greyish, the marginal spots less distinct, and the 

 silver mark more open, sometimes like the L of Progne, sometimes like the mark 

 of Comma. 



This species is found abundantly in certain localities on the Catskill Moun- 

 tains, New York. It is also found at Fort Simpson, at Albany River, and 

 Lake Winnipeg. It resembles C. album, of Europe, and has been supposed 

 to be identical with that species. It differs, however, in many respects. I 

 am informed by Mr. H. T. Stainton, that it is the species which follows Vanessa 



Progne as " Vanessa ? " in the list of Lepidoptera of the British Museum, 



Part I., 1844, and that it is regarded as " a distinct unnamed species." 



Thecla Californica, nov. sp. 



Expands 1-3 inch. Size and form of Falacer. 



Male. Upper side light brown; primaries with a smooth oval spot on 

 disc ; near the inner angle two faint fulvous submarginal spots, and 

 at anal angle of secondaries three fulvous lunules, the middle one deep- 

 est colored, and sometimes the two next anal angle resting on black spots ; tail 

 long, black tipped with white ; a white line from its base to anal angle ; the 

 fringe against this line is black, but elsewhere whitish without, brown next the 

 margin ; anal angle black. 



Under side grey with a reddish brown tint ; both wings have a straight dis- 

 cal bar edged with white ; primaries have, beyond the cell, a transverse band of 

 seven black spots, the one on costa, minute and preceding the others, the 

 seventh duplex ; each edged without by white ; a marginal row of pale fulvous 

 lunules almost obsolete towards apex, each surmounted with black, which is 

 edged above with white. Secondaries have a transverse band of seven large 

 black spots and a streak turning upward at the abdominal margin ; the fifth 

 of these spots from costa precedes the line, and the seventh is largest and cor- 

 date ; all edged without by white ; a marginal row of orange lunules, small or 

 obsolete towards the outer angle, but large and deep colored next anal angle, 

 extending up the abdominal margin and at the angle enclosing a pale blue 

 spot which is sprinkled with black atoms ; the lunule beyond this rests upon 

 a small black triangle, and all the lunules are surmounted with black, which 

 is edged above with white ; the whole hind margin of both wings is edged with 

 a white line. 



Female. The inner angle of primaries and the hind margin of secondaries 

 next anal angle suffused with pale fulvous; under side soiled white.

Thecla vjridis, nov. sp. 



Expands 1-2 inch. 



Upper side of both sexes blackish ; the male has a smooth oval spot on disc 

 of primaries ; hind margin of secondaries a little crenated towards anal angle; 

 fringe whitish, at anal angle brown. 



Under side uniform deep green, except on inner margin of primaries, where 

 it is brownish grey ; costal edge of primaries fulvous ; across the green shade 

 runs a common sinuous band of elongated, clear-white spots ; fringe of second- 

 aries brown at the extremities of the nervures ; antennae white ; club dark 

 brown.
