them and the species may really range east I have heretofore re- 

 garded this species as a form of congermana Morr., and have so 

 named it in collections. The receipt of additional material proves 

 them distinct. The peculiar, dead, chalky tinge of the primaries is 

 distinctive of the new species, and to this should be added the much 

 more pointed shape of these wings. 



Dr. Barnes long since suggested the separation of the Colorado 

 species; but I was unwilling to do so until I had better material of 

 congermana. Of the dull yellow shade at the apex and inner angle 

 of Mr. Morrison's species no trace appears in any example of artesta. 



Triclkdea nova n. sp. — Ground color pale grayish luteous, with a variably 

 marked reddish tint. Head and thorax immaculate, save for a variable powder- 

 ing of black scales which are most obvious on the thoracic disc. Primaries pow- 

 dered with black or smoky scales irregularly distributed, so as to give the wing 

 a mottled and suffused appearance. The normal maculation is all present, not 

 contrasting, more or less broken and sometimes obscured. Basal line geminate, 

 usually well marked iu its entire course. T. a. line geminate, the inner part 

 tending to become vague and obscured ; as a whole outwardly oblique, irregu- 

 larly outcurved in the interspaces. T. p. line geminate, outer portion obscure, 

 inner part lunulate or crenulate, also tending to become lost so as to leave a series 

 of black venular marks emphasized by following white dots ; as a whole the line 

 is moderate outcurved over the cell and only a little incurved below it. S. t. line 

 pale, broken, irregular, sometimes emphasized by preceding darker shades and 

 spots, sometimes by dusky cloudings in the terminal space. A series of blackish 

 terminal lunules. Fringes with a dusky interline, cut with white opposite the 

 veins, the margins just a little notched. All the veins more or less obviously 

 dusky, the median vein sometimes quite markedly so. Claviform small, with a 

 variably evident dusky outline. Orbicular small, oval, with a darker outline, a 

 pale annulus within this and a dusky centre; the latter may be lacking, leaving 

 the en,tire spot a little paler than the ground color. Reniform large, broad, filled 

 with blackish, a little constricted centrally ; a pale annulus within a border of 

 blackish scales defines the spot at the sides, the upper and lower margins tending 

 to become obscure. An obscure smoky median shade baud is visible below the 

 dark reniform. Secondaries pellucid white at base, becoming smoky toward the 

 margins; more so in the female than in the male. Beneath white, powdery; 

 primaries with veins marked outwardly; a series of blackish venular marks rep- 

 resenting the t. p. line; a dark lunule, the reniform spot; while a pale s. t. line is 

 obvious through an outer dusky margin. Secondaries with the veius smoky, a 

 small dark discal spot and a narrow smoky outer border. Expands 1.40-1.52 

 inches = 35-38 mm.
