bent dowawards a little, near the apex; outer margin long, the lower 

 half disposed to be parallel with the costa of the primaries. They reach 

 to the basal two-thirds of the abdomen. Legs short, femora and tibiae 

 densely pilose. The tibiae are shorter than usual and broadly pilose. 

 Outer tibial spurs twice the size of the inner. Tarsi small. 



Abdomen much slenderer than usual 5 anal tuft of S bifid. 



In the female the fore-wings are broader, not sd angulated on the 

 outer margin, the secondaries are more produced at the apex, and they 

 reach nearer the tip of the addomen than in the male.

Ccelodasys Edmandsii n. sp. 



% . Somewhat olivaceous ashen, thorax dark above. No discal dot, 

 but that region is slightly discolored. The outer transverse straight 

 line composed of reddish lunules. lined within with white scallops is 

 very distinct. Apical region white, margined below with a reddish 

 streak. Three dark costo-apical dots, of which the outer one is paral- 

 lel to one removed towards the middle of the wing. The internal angle 

 of the wing is enclosed by a curved series of dark dots. 



Secondaries pale, whitish beneath. Legs anuulated with white. 



Length of body, .55; exp. wings, 1.20 inch. 



Cambridge, (Miss Kdmands.) 



This species is closely related to O. unicornis, but it is smaller, the fore 

 wings are narrower in proportion, and the apex is more produced; like- 

 wise the internal angle is more rounded, and the outer margin is more 

 oblique. The slender abdomen is a little more acute. It wants also 

 the distinct linear discal dot of C. unicornis. Within, the wings do 

 not seem to be crossed by waved lines, and the geminate costo-apical 

 spots are much smaller, while it wants the dark transverse thoracic line 

 present in C. unicornis. 



Respectfully dedicated to Miss A. M. Edmands. of Cambridge.
