Say, 1. ¢., 82, 2, gives the locality Massachusetts for his C. opaca, 
and adds, — “ for this species I am indebted to Dr. Harris.” Of 
course the specimens No. 44 are types. The males, No. 43, are im- 
mature. All these specimens belong to C. maculata. 
Calopteryx maculata is a species spread over the whole United 
States east of the Rocky Mountains. I have seen a great number of 
specimens from Maine to Florida, and from Illinois to Texas. I have 
seen some females from Illinois and Maine which differ in the color- 
ation of the wings, and are more similar to the European C. virgo. 
Nevertheless the males of the same localities, even found together 
with such females, are not different from C. maculata. It would be 
interesting to have further observations on this variety.

The male, No. 53, and the female, No. 54, agree well with Say’s 
description, and as he gives the locality Massachusetts, and adds, — 
“a female specimen, a/so sent me by Dr. Harris,” there is no doubt 
of the typical character of the specimens in the collection. I have 
seen the species from Hudson’s Bay, Maine and Massachusetts, and 
they are surely identical with the specimens from Hudson’s Bay, 
quoted under C. virginica in my Synopsis, from Baron’ De Selys 
Longchamps’ collection. At the time the Synopsis and the Mono- 
‘ graph of the Calopterygines were published I had seen no specimen. 
Even now the specimens from Georgia, in the British Museum, and 
from Virginia, quoted by Drury, should be examined again. The 
name given by Say has the priority over the name given by West- 
wood to Drury’s species. 
There is a young larva of a Calopteryx in the collection, the only 
T have seen until now from the United States.
