at the base. Hind wing with vein 8 arising free, then bent down and 

 usually anastomosing shortly with 7 near the base of the cells ; three 

 internal veins." Additional features of the venation in Cnidocampa 

 are as follows : Fore wing. Cell completely divided by a longitudi- 

 nal vein which forks externally, the hind fork joining the base of 5, 

 the other the base of 6. Base of 4 and 5 joined by a faint cross 

 vein, the two veins a little nearer to each other at their bases than 

 are 3 and 4. Vein 3 arising from the median a little more than half 

 way from 2 to 4. A cross vein passes forward from the junction of 

 the anterior fork and the base of 6, to the subcostal. Veins 7 and 

 10 connate or stalked from the upper angle of the cell; 8 and 9 

 stalked from near the basal fourth. Vein 1 1 leaving the subcosta at 

 about the middle of the cell and bending forward, and from a point 

 about opposite the end of the cell onward, running very close to vein 

 12. Hind half of the cell longer and narrower than the front half. 

 Hind wing. Cell divided by a longitudinal vein from its outer end, 

 which joins the median vein at the inner third of the cell. Vein 2 

 arising from about the middle of this posterior cell ; veins 3, 4 and 

 5 from near its end, 4 being from its apex. The cross vein forming 

 the external end of the anterior half of the cell arises a little beyond 

 the middle of the posterior half of the cell and passes forward and a 

 little obliquely outward, Veins 6 and 7 from a short stalk from the 

 upper angle of the cell ; 5 and 6 approaching each other somewhat 

 then diverging. 



Legs rather stout, the under side of the femora quite heavily fringed 

 with hair-like scales. Fore and hind tibia and metatarsus fringed on 

 the outer side with long hair- like scales, longer in the male; the 

 same conditions being present to a less degree on the middle legs, 

 and here too, more developed in the male. Hind tibia with a pair of 

 spurs on the inner side at the tip and a second pair near the middle, 

 all four spurs being nearly of equal length. 



Cnidocampa ftavescens (Walk.) Expanse of wings 32 to 40 mm. 

 Head, thorax and inner portion of the wings above, dull chrome 

 yellow ; outer portion of fore wings light chestnut brown with a yel- 

 lowish tinge inwardly, darker toward the outer margin. Near the 

 hind margin of the wing in this region the yellowish is replaced by a 

 pinkish tinge. Front of the head below the horizontal bar of the 

 T-shaped ridge of scales, brown - pink ; palpi light chestnut, with 

 numerous black scales giving a finely speckled appearance, their tips
