 and on the secondaries especially so beyond the outer line which, with 

 the discal dot, is much plainer than on the upper surface. Head and

Dryopteris irrorata n. s^j. 



This species is of a bright ferruginous or brick red, dusted above 

 with brown abbreviated lines and dots, but beneath clear reddish. 



Palpi and front of head of a bright rusty red, thorax and fore wings 

 slightly shaded with brown. Both pairs of wings are marked nearly 

 alike, being crossed by transverse irrorations which are united into lines 

 near the base of the wing. Within the middle of the wing is a slightly 

 curved irregularly zigzag dark line, which is deeply sinuate in the me- 

 dian space. On the outer fourth of the wing is a line of the same color, 

 which makes an acute angle before reaching the apex of the wing, and 

 then suddenly bends back upon the costa. Just beyond this line is a 

 dark transverse streak which only touches the outer edge at the lower 

 part of the apex, which is nearly black. 



On the secondaries are two parallel dark somewhat zigzag lines, the 

 inner being half as long as the outer one. Beneath, the outer line 

 only is reproduced, being straight on the fore wings, but a little sinuate 

 on the hind wings. 



Length of body, .45; exp. wings, 1.40 inch.
