372 THE CANADIAN ENTOMOLOGIST. 



antennae, as mentioned by Grote, and this prevails in all but one of my 

 specimens, not dusky or dark brown, mixed with white, as in limitaria. 

 When fresh they are washed and streaked with green, but not in the 

 fantastic fashion of limitaria. From this latter a number of extreme forms 

 may be selected, but they grade into one another in a large series. In his 

 description of Z. veiiiata (Mono., page 183), Dr. Packard speaks of the 

 snow-white front with black hair-line below antenn;ie, clearly indicating by 

 this and other similarities that he was describing a specimen of 

 anguilineata. Yet he figures (Plate 8, fig. 13) a form of limitaria. 

 Under his reference to angtiilineata (page 184), which is very brief, he 

 says "specimens may yet be found connecting L. vcrnaia with this." To 

 my mind there is no doubt they are the same, the older name of Grote 

 taking precedence. The type of angiiilifieata came, I think, from 

 Pennsylvania, and while single examples have been taken elsewhere, like 

 the Massachusetts specimen, and my own from Long Island, its home 

 centre seems to lie in the mountains of Pennsylvania. In the spring of 

 1906 I forwarded to Mr. Prout for comparison with Walker's types in the 

 British Museum, a small lot of limitaria. He writes of them thus : 

 '■'■ Lobophorata, WsYk.; fusifasciata, Walk., and longipennis, Walk, (all in 

 coll. of Brit. Mus.), are clearly forms of the variable species you call 

 limitaria, Walk., and I shall accept your synonymy." I find also that 

 Prof. Grote, writing in C.-vn. Ent., Vol. 8, p. 152, long ago reached the 

 same conclusion, but at that time overlooked the older name oi limitaria. 



With abundant material before me, I therefore conclude that the 

 species of Nyctobia should be listed as follows : 



limitaria, Walk. 



= lobophorata, Walk. 



= fusifasciata. Walk. 



= longipennis, Walk. 



= Cystiopteryx viridata, Grote (Hulst in error), 

 anguilineata, Grote. 



= vernata. Pack, 

 nigroangulata, Strecker. 

 viridata, Packard. 



= Agra eborata, Hulst (in error). 



A word as to viridata, Pack. This is the species upon which Dr. 

 Hulst founded his genus Agia, making it his type. He says in closing : 

 " Very close to Nyctobia, differing mostly in the presence of the
