under circumstances which lead to the belief that the larva may 

 be a wood-feeder like Scolecocampa. The horned clypeus is evi- 

 dently correlated with function in these internal feeders. In 

 Mclanopyga the thorax and forewings are dusky yellow; the 

 stigmata concolorous ; the lines oblique, uneven, the posterior 

 line dentate, the median shade indicated. In color the lines are 

 dark, with a reddish tinge; the terminal space shaded with dusky 

 without the dentate subterminal line. In color this species is 

 paler than F7//;/z)?^rt', the abdomen more grayish. The hind wings 

 are stained with reddish ; in one specimen the border remains 

 grayish. Expanse 40 mil. Two ? specimens reared by Prof. 

 Comstock from larva boring in leaf-stalks of pond lily. I have a 

 specimen of Vulnifica ? , collected by Mr. Schwarz in Florida with 

 pale anal tuft. I might be inclined to consider the paler color 

 and black anal tuft varietal characters, but the transverse posterior 

 line is less rounded and more acutely angulated below costa in 

 A. Melanopyga.

This little beauty is gratefully dedicated to my faithful fac- 

 totum, Mr. I. Doll, who, undaunted by the strain of a torrid zone 

 and the attacks of Indians, pursues his duty of collecting mater- 

 ial for our Science.
