distinct terminal dots, all black. One male. Am. Sept." I do not 



identify this description. 



t Spinigera Guen., Koct. 1, 45. 



" Shape and ai)pearance of Furcifera. Fore wings of an ash gray 

 powdered with blackish, with the markings indeterminate. Basal line 

 very fine and joining the extra-basal. Orbicular small, rounded. Eeni- 

 form very large, soiled with blackish. T. p. line well marked, denticu- 

 late, black, fine, but shaded largely although vaguely with brownish 5 

 a series of small terminal points. Fringe hardly cut. The inferior 

 transversal dash running to a fine point but more visible than the rest. 

 Hind wings of a yellowish gray, nearly concolorous, beneath yellowish 

 white, with a discoidal line and the lunules little marked. New York. 

 Coll. Doubleday. Two males in bad condition, which perhaps renders 

 the above description incomplete." In collections the name " Spinigera^^ 

 is attached to specimens which are probably the same as PalUdicoma, 

 which has the t. p. line denticulate, but acutely so, and shaded with 

 white, and belongs to a different group from this which Guenee puts in 

 his genus Semapliora the equivalent of Tricena. 

 Tritona Hiibn., Zutr., 107-8 5 Guen., Il^oct. 1, 42. Canada to Southern 



States. 

 Falcula Grote, Can. Ent. 9, 86 ; Coquill., Papilio 1, 6 ; Larva on hazel. 

 This is distinguishable from Tritona by the bright brown edging of 

 the thoracic tuft behind ', the dash at internal angle does not cross or . 

 indent the transverse posterior line. In this it resembles parallela. 

 Grisea Walk., C. B. M. Noct., 56 5 ? pudorata Morr., Ann. I:^. Y. Lye. 93, 

 1875. Canada to Middle States. Mr. Morrison thinks that Guen6e's 

 tritona may not be Hiibner's. His description of pudorata agrees 

 fairly with grisea as determined from notes of mine on the B. M. Coll. 

 There is some variation probably in tone of secondaries, for Mr. Mor- 

 rison calls the hind wings of tritona "• yellow." My specimens have 

 the wings different shades of fuscous, with, perhaps, a faintly yellow- 

 ish tinge.

 ]Interrupta Guen., Noct. 1, 46 ; Am. Sept. This is described with the 

 caterpillar from a drawing of Abbot's. It would be a good thing if 

 the drawings (which. I believe are either in Boston or in the coll. 

 British Museum), which have been made the basis of descriptions by 

 Guen^e, could be published. I hardly think the species can be rcog- 

 nized without such help.
