Ichthyura jocosa H. Edw., Ent. Americana ii, 10, April, 1886. 

 One 9 , type; Indian River, Fla. This is only a small inclusa, 

 differing from the normal form of the species in the inner arm of 

 the V being firmer and less sinuous, being interrupted at the 

 union with it of the short middle line which ends on the hind 

 edge of the wing, while in inclusa the line is not usually inter- 

 rupted, although two of the inclusa in Mr. Edwards' collection 

 do have the line interrupted as in his type of / jocosa. The 

 latter is also more generally subochreous than usual, and without 

 a line on the hind wing. 



Ichthyuria bifiria\\. Edwards, Ent. Americana ii, 167, Decem- 

 ber, 1886. This is very near / bnicei, the wings being of the 

 same shape, and the moth of the same size, with the same beau- 

 tiful lilac shades on the fore wings, thus differing from any other 

 species, though it may yet be found to intergrade with brucei. 

 The single type differs from Mr. Edwards' type of brucei, in the 

 oblique silver-white costal streak being more sinuous, as is also the 

 line across the wing which forms the continuation of the streak. 

 On the other hand the other (inner; arm of the V is straight, not 

 sinuous, the inner two lines are about the same. The submar- 

 ginal spots and streaks are the same in both species. 



The most important synonymy of the North American species 

 of Ichthyura may provisionally, at least, be as follows:

 (perhaps a var. of van) 



Walker's Ichthyura apicalis is possibly / vau, but it is impossible 

 to determine from his brief description, as he does not say whether 

 the albida maculaque costali is oblique or not. In Barnston's 

 MS. description quoted by Walker, the larva is described as 

 " brown, thick, with sixteen feet, and with a band on part of the 

 back;" "feeds on the Poplar leaf." This description will apply 

 better to vau than to any other species known to me, as I have 

 reared va^t from the Poplar, and the larva is brown, short, though 

 not with " a band on part of the back."
