to base of wing; Mi from just below areole ; R, and Rj slightly stalked; R. and 

 R3 from areole ; Ri from middle of cell ; secondaries with R and Mi from a point 

 or slightly stalked ; "cellula intrusa" wanting on both wings. 



In the specimens examined by us a perpendicular cross-vein ex- 

 tended from the point of origin of R and Mj to S. C. vein, but we con- 

 sider this, as previously stated, a rather doubtful generic character. 

 The genus may readily be separated from the following by the lack 

 of the "cellula intrusa" on both wings.

"Head, body and primaries whitish gray. Antennae serrated. Abdomen 

 with a dorsal row of brownish spots. Primaries, the subcostal nervure marked 

 with black from near the base to ^ the length of the wing. Two lower branches 

 of the subcostal partly defined with black. Median nervure black as are also 

 the three branches, the upper one only partly so, the black not extending to the 

 e.xterior margin. The internal vein black, a couple of fine black lines run from 

 this to the inner margin near the base and also at and near the apical angle. 

 Secondaries white sprinkled with gray atoms. Under surface nearly as above, 

 and with a few faint striae on costa of secondaries. Expands i>4 '"■ Type Loc.

This very distinct species is easily recognizable from the original 

 description ; we would characterize the antennae as bipectinate rather 

 than serrate, and note that on underside the veins are much more 

 strongly marked than above. Early stages unknown. Type in Coll.

Antennae pectinate, less strongly in 2 than $ ; palpi porrect, short, barely 

 extending beyond front, third joint conical ; vestiture of front and thorax largely 

 composed of hair-like scales ; abdomen projecting well beyond hind-wings, with 

 anal tuft; hind-tibiae with single pair of apical spurs; primaries with anal veins
