520 Mr. L. B. Piout on 



nearly five-s'iKths, incurved in lower half, followed on costa 

 by a triaiisjular red-brown apical blotch, and on inner margin 

 by an erect ov^al spot reaching submediau fold, the line itself 

 marked by red-brown dots on the veins except R"', each dot 

 followed by some white scales ; a small red-brown cell-dot ; 

 fringe yellow (damaged). Hind wing pale yellow, with red- 

 brown cell-dot and postmedian curved row of vein-dots ; a 

 submarginal row (ratlier iiearer to p:>stmedian than to 

 termen) showing through from beneath Underside some- 

 what paler, with the markings fainter; dots of outer line of 

 fore wing doubled ; hind w^ing with submarginal carved row 

 of red-brown dot*. 



Mexico, without more exact locality ; one (^ . 



I have been unable to find a genus with which this species 

 a'zrees in its characters. The shape and coloration recall 

 GynopterijX) though it is a somewhat more slender-looking 

 species ; but its subcostal venation shows triple short 

 anastomosis (SG^ with C, SC^ — arising from cell — with SC^ 

 and again with SC'^"*) ; the discocellulars are incurved; C of 

 the hind wing is closely approximated to SO to one-half of 

 cell ; the hairs of the face are abraded, but the face itself is 

 not protuberant ; the auteunal pectinations are short and. 

 rather stout. 



Gynopteryx gladiaria ustimacula, sub -p. n. 



c? . 29-37 mm. — Agrees with typical G. gladiar'ia, Guen., 

 in structure and in ground-colour; subapical spot of fore 

 wing always strongly developed, usually larger than in 

 typical gladiaria; autemediau line grey, usually well ex- 

 pressed, sometimes thick, sometimes terminating in a round, 

 scorched-coloured spot on inner margin ; postmedian some- 

 what incurved, therefore further from termen, in its lower 

 part, than in atiy but very rare aberrations of gladiaria ; 

 ending in a large burnt-coloured spot on inner margin ; sub- 

 marginal spots usually developed, though not as deeply as in 

 the ab. seriana, somttimes connected into a zigzag line. 

 Hind wing with median line and submarginal spots or line 

 Avell exj ressed. Undrrside with the markings well ex- 

 pressed, usually redder-tinted thun in the other forms, the 

 postmedian curved, as above. 



Chanchamayo (type and others) and Pozuzo, E. Peru, a 

 short series ; numerous others seen. 



With so variable a species as G. gladiaria this form would 

 scarcely have merited a separate name, but that it forms a 

 a definite race in E. Peru. The characteristic spot on inner 

 margin at end of postmedian is much larger than in even
