The Genus Perilestes 13 



distinguishable anteapical pale area, the apex is darker brown to black; 

 8 shading from brown at base to nearly 'black at the apex] orl, largely- 

 brown throughout ; 9 similar to 8 but darker ; 10 black, or 9 and 10 brown. 

 Seen from the side 1-6 similar to those of remotus but the basal inferior 

 spot on 2 wanting or very small ; 7-9 largely pale, each more or less darker 

 at apex and along the ventral border; 10 black or brown. Sternum of 1 

 pale; anterior lamina pale, the posterior processes darkening to brown 

 with the ventral edge of the plate black; 3-6 each with the lateral color 

 pattern carried across the sternum; sternum of 7 largely dark to black; 

 8 black with a median pale area nearer base than apex; 9 and 10 pal<< 

 (blue? in life), the latter discolored by postmortem changes. Appen- 

 dages pale dull yellow to brownish horn color, slightly darker at base. 



Length of the wing or lobe on the expanded postero-ventral margin of 

 the tergum of 2 about .6, and the distance from the apex of this lobe to 

 the antero-ventral angle of the tergum about 1.8. 



Female. — Head similar to that of the male. 



Prothorax, thorax, mesostigmal lamina, coxae, legs, venation and stigma 

 similar to those of the male. 



Abdominal segments 1-7 similar to those of the male; seen from above 

 8 and 10 are black or nearly so, and 9 is about as in remotus with the dark 

 bar slightly narrower in the basal two-thirds; seen from the side 8 and 10 

 are brown, and 9 is largely blue, shading apically into the brown of the 

 apically widened dorsal band, with the blue and brown shading below 

 into black along the entire ventral border. Sternum of 1 and 2 pale, the 

 latter with or without a trace of dark at midlength; 3-6 with the lateral 

 color pattern of each carried across the sternum; sternum of 7 largely 

 dark, pale for a short distance at the base; of 8 largely pale (blue? in life), 

 an irregular dark median area beginning before the middle and extending 

 to the apex. Appendages brown, shaped as in magdalenae. The valvular 

 styles with points of attachment under the appendages.

Postnodals front wing, 13 (12.5% female), 14' (50% males, 50% fe- 

 males), or 15 (50% males, 37.5% females) ; hind wing, 11 (33.3% males), 

 12 (33.3% males, 62.5% females), or 13 (33.3% males, 37.5% females). 



Mg in front wing arising between the first and second postnodals (100% 

 males, 100% females) ; in the hind wing at the first postnodal (66.7% 

 males, 62.5% females), or between the first and second postnodals (33.3% 

 males, 37.5% females).

 the seventh postnodal (50% males, 50% females), or at the eighth post- 

 nodal (50% males, 37.5% females) ; in the hind wing at the sixth postnodal 

 (66.7% males, 62.5% females), or at the seventh postnodal (33.3% males, 

 37.5% females).
