sent me information in regard to specimens tin the Scudder 

 collection at the Museum of Comparative Zoology, Cambridge. 

 Massachusetts. A male and female, labeled conspiciia are be- 

 yond doubt part of the type material of knmskaka, the pre- 

 sumption being that one male had been used to make the geni- 

 tal ic mount and it may still be in the Scudder collection. Dr. 

 A. W. Lindsey examined most of the collections of Iowa but- 

 terflies when he prepared a State list, but did not record this 

 species. He also states later that he never took anything in 

 western Iowa which might have been this species. During the 

 past summer Mr. R. A. Leussler made a special search for the 

 species at the type locality, but failed to find it. 



From all the evidence I came to the conclusion that we were 

 probably dealing with a known species, one previously de- 

 scribed. By elimination it was easy to narrow down the pos- 

 sibilities to a very few species and finally to the one that the 

 description fitted best. This proved to be Atrytonc byssns 

 Edwards, described over forty years ago. The male genitalia 

 of b\ssus are very distinct and not like any other species and 

 agree with the figures of the genitalia of knmskaka as figured 

 by Scudder. This resemblance has been also noted by Barnes 

 and McDunnough, who state that the two must be nearly re- 

 lated. We know very little about the species. The type local- 

 ity of bvssus was the Indian River, Florida, the presumption 

 being that they were taken by Dr. Wm. Wittfeld at Georgiana, 

 in the fall. Mrs. A. T. Slosson took it on Biscayne L5ay, Flor- 

 ida. The Edwards Catalog of 1884 also gives Texas. \Ye 

 have a specimen from the Indian River that bears a pin label 

 with October on it. but all the others are without date of cap- 

 tr.rc. Doubtless the species flies in the Gulf States and may 

 be found in some of the States to the North, the Iowa speci- 

 mens being rare visitors.
