The Genus Perilestes 29 



Thorax similar to that of the male, the antehumeral yellow stripe very 

 slightly wider. 



Mesostigmal lamina similar to that of the male. 



Legs similar to those of the male, the basal streak of brown on the dorso- 

 anterior surface of the tibiae scarcely evident in the female. 



Venation similar to that of the male. 



Abdomen seen from above : 1 and 2 similar to those of the male but 1 

 paler at base; 3 black following the pale basal ring, fading out through 

 brown beyond the midlength of the segment to the anteapical pale, the 

 apical 1.5 m.m. black as in the male ; 4 and 5 similar to 3 ; 6 brown rather 

 than black postbasally, and the segment nearly uniformly colored, the 

 apical black and anteapical paler areas scarcely distinguishable; 7 and 8 

 similar to 6, slightly darker, the pale basal ring reduced on 7 and wanting 

 on 8; 9 yellowish brown, narrowly and indefinitely black in the midline 

 and on the apical edge, dark brown to black on either side apically, these 

 lateral dark areas widely separated by the paler dorsal color; 10 black. 

 Seen from the side 1 and 2 are similar to those of the male ; on 3 and 4 the 

 basal and subapical pale areas are joined along the ventral border but on 5 

 the median dark of the tergum separates them and on 6 the subapical pale 

 area is scarcely or not distinguishable and the postbasal pale area is con- 

 tinued very briefly along the ventral margin ; 7 and 8 brown, slightly paler 

 toward the ventral margin and basally on 7 and a small ventro-posterior 

 brown area on 8 ; 9 pale yellowish brown, lightest along the ventral margin, 

 apically dark brown or black for a width of about one-third m.m., this 

 black narrowing ventrally, and with a small ventro-anterior brown area ; 

 10 black. Sternum of 1 pale ; 2 pale with a postbasal and an apical black 

 or brown area ; 3-6 similar, with the postbasal dark area on each extensive, 

 occupying half the length of the sternum or more ; 7 pale at base, then dark, 

 apparently without an anteapical pale region; 8 pale (probably blue in 

 life) with a narrow longitudinal median black line scarcely reaching base 

 or apex and widest at about midlength of the sternum. Appendages black, 

 shaped like those of magdalenae. Valvular styles at their point of attach- 

 ment distal to the level of the apex of 10. 



Venational characters based on three males and one female 



Postnodals front wing, 13 (33.3% males), or 14 (66.7% males, 100% 

 females) ; hind wing, 10 (16.7% males), 12 (66.7% males, 50% females), 13 

 (16.7% males), or 14 (50% females). 



M3 in front wing arising at the first postnodal (50% males, 100% fe- 

 males), or between the first and second postnodals (50% males) ; in the 

 hind wing at the first postnodal (100% males, 100% females). 



Rs in front wing arising at the eighth postnodal (50% males, 100%' 

 females), or at the ninth postnodal (50% males) ; in the hind wing at the 

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

 100% females). 



M2 in front wing arising at or near the ninth postnodal (33.3% males, 

 100% females), or at or near the tenth postnodal (66.7% males) ; in the
