Nadata Doubledayi n. sp. 



Compared with N. glhhosa the antennae are not so broadly and hea- 

 vily pectinated, the branches decrease much more rapidly in size, the 

 front of the head is broader, and the tufts at the base of the antennae 

 are more spreading and conspicuous. The palpi are smaller and tipped 

 with black, when in N. (jibhosa they are tawny throughout. This spe- 

 cies is throughout lighter colored. The costii of the primaries is not so 

 convex towards the apex, outer margin hardly scalloped, and the very 

 shallow scallops are filled in with brown instead of silvery scales, as in 

 gibbosa. The two transverse lines are paler and more sinuate. The 

 two discal dots are the same, but the inner clear tawny space is much 

 paler in Doubledayi. The secondaries are paler and lighter, and not 

 margined with brown. Apex more rectangular, and the outer margin 

 not so full as in gibbosa., while it is smaller, while the thoracic tuft is 

 broader at the base, and above more acute. 



Length of body % , .85. 



Dedicated to Mr. E. Doubleday, who, when traveling through the 

 United States, added so much to our knowledge of this family, and 

 who, in his letters to Harris, indicated that there were three species of 

 this genus existing in this country.
