 bordered with dark gray, a brown crossband extends from costa be- 

 fore apex of auxiliary vein to middle of discal cell near its base, its 

 lower inner angle indistinctly prolonged into base of third posterior 

 cell; a second brown band extends from costa just before apex of 

 first vein to middle of discal cell, passing over the small crossvein; 

 hind cross yein broadly bordered with brown, and above it is a 

 brown spot, on the second vein, a brown streak along the costa in

1785 Spilographa inaequalis Coquillet, new species. 



Near tortilis but the small crossvein is situated distinctly beyond 

 the apex of the first vein and the brown crossband which passes 

 over it is widely separated from the one on the hind crossvein. 

 Yellow, the abdomen reddish yellow, on ocellar dot and the basal 

 segment of the ovipositor black, the latter only slightly longer than 

 the last abdominal segment; bristles and hairs black, body polished; 

 wings hyaline, anal cell and base of the first basal yellowish, a 

 brownish crossband extends from forking of second and third 

 veins to lower and outer angle of anal cell; an arcuate, uneven 

 brown band extends from costa just before apex of first vein almost 

 to center of third posterior cell, passing over the small crossvein; a 

 second uneven band extends from costa nearly midway between 

 apices of first and second veins to apex of fifth vein, passing over 

 the hind crossvein; apex of wing broadly bordered with brown from 

 before apex of second vein to beyond apex of fourth; small cross- 

 vein very slightly beyond middle of discal cell; Length 4 mm. A
