with ten small brown spots, as follows : one at base and one at apex of pterostigma, 

 one at connection of radial sector with median, and one at the termination of the each 

 of the seven veins. Wings slender ; pterostigma three times as long as wide, equally 

 wide throughout, radial sector and median meeting at but one point which is fuscous ; 

 no posterior cell ; fork of radial sector nearer base than last fork of the median ; vena- 

 tion yellowish and brown in fore wings, brown in hind wings. Length to tip of wings 

 2 mm. 



Several specimens from Berkeley, Cal. Easily known by the ten 

 dots on wings. 

 Cascilius pinicola, sp. nov. 



Pale yellow throughout ; a reddish spot each side of ocelli ; antennce rather heavy 

 and brown. Wings pale yellowish, venation of same color. Wings slender, ptero- 

 stigma long, rounded off behind ; radial sector and median vein united for about the 

 width of a cell ; radial sector forked before the second fork of the median vein ; pos- 

 terior cell half-elliptical. Length to tip of wings 2.5 mm. 



Several specimens from Falls Church, Va., October 10, in pine 

 trees. Appears to be related to C. aiirantiacus, but separated by 

 lack of black posterior venation, and duller colored wings.

very much like P. griseolineatits Enderlein. The pterostigma very long, and 

 rounded behind ; the radial sector forked close to base ; the median vein with but 

 one fork which is toward tip of wing, beyond end of pterostigma, the posterior cell is 

 very large, elongate, larger than the pterostigma. The legs are pale, the hind femora 

 dark at base. Length to tip of wings 4 mm. 



One specimen from Falls Church, Va., June 8. The four species 

 of this genus all come from Peru, and its discovery in the United 

 States is of much interest.
