The Genus Perilestes 19 



mains distinctly and conspicuously black; ventro-lateral carina and meta- 

 sternum entirely pale except for the merest trace of a brown line on the 

 median suture from the third coxae to the level of the angle of the latero- 

 ventral carinae. 



Mesostigmal lamina low, the edge nearly uniformly curved. 



Coxae pale, a small dark ar6a on the anterior face of the third. Femora 

 largely pale, obscurely darker above, black beneath and at the apex. Tibiae 

 pale, the first tibia narrowly dark streaked above and all dark streaked 

 beneath. 



Venation and stigma similar to those of the male. 



Abdominal segments 1-6 patterned about as in the male but with the 

 median dark area of 4—6 paler, darkest immediately following the post- 

 basal pale area, on 6 scarcely darker than the anteapical pale area; the 

 postbasal pale area on 4-7 is slightly reduced in area in its dorsal but not 

 in its lower ventral part as compared with the male and the apical dark area 

 grows progressively paler posteriorly so it is brown instead of black on 6 ; 

 7 reddish brown, the postbasal pale areas widely separated in the median 

 line ; 8-10 black above, on 9 reduced to a well-defined median longitudinal 

 bar about .8 wide basally which widens laterally, at about two-thirds the 

 length of the segment, and passes into brown on the sides, terminating at 

 the apex at about midheighth of the segment; this black bar is bounded 

 basally on either side by a large blue sharply defined lateral spot ; sides of 

 9 largely blue, the ventral border at midlength narrowly black, from which 

 point the ventral black widens in both directions to base and apex giving 

 a circular form to the lower edge of the lateral blue spot. Sternum of 1 

 largely pale, of 2 largely black, of 8 largely pale (blue? in life). Appen- 

 dages pale brown, black at extreme apex, flattened cone-shaped, acute; 

 as compared with those of reniotus they are less tapering in the apical two- 

 thirds or three-fourths and less acute, — evident differences when direct 

 comparisons are made but difficult to describe. Valvular styles at their 

 point of attachment about at the level of the apex of 10. 



Venational characters based on four males and two females 



Postnodals front wing, 13 (50% males, 25% females), 14 (50% males, 

 25% females), 15 (25% females), or 16 (25% females); hind wing, 10 

 (12.5% males), 11 (37.5% males), 12 (37.5% males), 13 (12.5% males, 

 75% females), or 14 (25% females). 



M3 in both front and hind wings arising between the first and second post- 

 nodals (100% males, 100% females). 



Rs in front wing arising at the seventh postnodal (75% males, 25% 

 females), or at the eighth postnodal (25% males, 75% females) ; in the hind 

 wing at the sixth postnodal (37.5% males), at the seventh postnodal (62.5% 

 males, 75% females), or at the eighth postnodal (25% females). 



M2 in front wing arising at or near the seventh postnodal (12.5% males), 

 at or near the eighth postnodal (62.5% males), at or near the ninth post- 

 nodal (25% males, 75% females), or at or near the tenth postnodal (25% 

 females) ; in the hind wing at or near the seventh postnodal (75% males),
