The larva appears to be undescribed. The adults occurred to me 

 at Tupper Lake, N. Y., flying on the leaves of water lilies in company 

 with N. maculalis Clem. They had evidently bred there as undevel- 

 oped specimens were seen on the leaves. Larvae occurred on the 

 plants in cases made of pieces of leaf, attached either to the leaf or 

 lower down on the gelatinous stem. The larvae were abundantly sup- 

 plied with tracheal filaments as Hart describes for Nymphula obscur- 

 alis Grote; but it proved impossible to breed them as they hibernated 

 in the water as larvae ,/£o I do not know to which species they belong. 



Nymphula nebulosalis Fernald. 

 Hydrocampa nebulosalis Fernald, Ent. Amer., lii, 127, 1887. 

 Hydrocampa nebulosalis Fernald, Smith list. Lep. Bor. Am., no. 4173, 1891. 

 Nymphula nebulosalis Fernald, Bull. 52, U. S. Nat. Mus., no. 4488, 1903. 



Fore wing rather bright ocherous yellow, the markings black, edged with white. 

 The markings are as in N. gyralis Hulst, but more diffused and partly lost in a brown 

 shade that overspreads the terminal and central parts, leaving a broad yellow area 

 without the discal mark; this mark is narrow, lunate; subterminal line retreating 

 from the margin below, sometimes interrupted. Hind wing white in the middle, the 

 base and a large discal mark yellow; mesial lines black, separating centrally to 

 enclose the discal yellow patch ; a broad yellow or fuscous yellow subterminal band ; 

 termen yellow with black line within. Legs spotted with white and fuscous yellow, 

 Expanse, 1 5 to 18 mm. 



This species is allied to JV. gyralis Hulst, but the sexes are alike. 

 It is even more nearly related to A r . icciusalis, Walk., from which it 

 differs only in being smaller and darker, the marks overspread with 

 brown.
