at base, the apex light yellow, the black oblique, occupying 

 about one-fourth the length above and about one-half the 

 length below ; inferior appendage brown. 



Wings hyaline, no trace of any colored areas, very faintly 

 greenish tinged to the nodus ; costa brown, narrowly and in- 

 conspicuously edged with pale greenish or yellowish blue. 

 Stigma dark brown, covering 4 to 4.5 cells in the front wing 

 and 5 to 5.5 in the hind wing; in one hind wing the cells pos- 

 terior to the stigma are abnormal. Antenodals front wing 11 

 or 12, hind wing 7 to 9 ; postnodals front wing 5 to 8, hind 

 wing 6 or 7 ; basal antenodal of second series present ; the dis- 

 tal thickened antenodal the fifth. Triangle of front wing 

 once crossed ; of hind wing free in one wing, once crossed in 

 three wings, the single uncrossed wing is abnormal in that the 

 anterior side of the triangle, instead of meeting M^ at or 

 slightly proximal to the distal anterior angle of the triangle, 

 meets the distal side of the triangle posteriorly to the distal 

 anterior angle a distance about equal to half the length of the 

 arculus ; the anterior side of the triangle in this abnormal wing 

 therefore occupies a position about midway between the an- 

 terior side of the triangle and the cross-vein of the triangle in 

 the normal wing, and takes the place of the two. The sub- 

 triangle is once crossed in all front wings and free in all hind 

 wings. Anal field of the front wing proximal to the triangle 

 two cells wide for a distance of two cells, counting the anterior 

 row; distal to the triangle the field is two cells wide for a dis- 

 tance of three or four cells. There are four cells in the prox- 

 imal row of postanal cells and three or four, usually three, in 

 the distal row. 



Legs short, femora reddish brown, shading into black at 

 apices, the first pair bluish gray beneath ; tibiae and tarsi black ; 

 tarsal claws dark reddish brown, the teeth and apices black.
