nialus, aspersus, carolus and rupinsulensis , species of which the 

 males have been taken in Maine. As we have also taken O. 

 johanmis about Orono, this specimen may prove to be the un- 

 described female of that species. 



[I have examined this female carefully, and have compared 

 it with a female carolus given me by Prof. Needham. I can 

 find no differences except that the pale colors of the former on 

 head and thorax are bright green, and that the yellow spots on 

 the sides of 2-7 are somewhat larger. Of course it may still 

 be the female of O. johannus. — P. P. CalvERT.]

This species proves to be fairly abundant at the original 

 locality, we having taken about seventy-five specimens in the 

 last three years. Females are scarce ; few are seen and only 

 half a dozen have been taken. They fly much more swiftly 

 and irregularly than the males, darting about over the pool 

 ovipositing here and there, and in a moment are gone into the 

 bushes. The species is apparently local, having never been 

 taken on any other stream, although we have seen at Sunk 

 Haze and Birch streams, Greenfield, what we supposed was 

 this form.

An abundant species. About forty specimens were taken in 

 June at the locality spoken of under O. a?iomalus in this article. 

 Later an occasional male was taken over Chemo stream, Bradley. 

 We have no idea when the eggs are laid.

Between August 24, and 29, 1899, we made a special trip to 

 Russell Stream, near Northeast Carry, Maine, to collect this 

 species. It was at this locality that in 1897 we took the single 

 male from which our description was drawn up. We followed 

 the stream up and down for two miles, several times a day, for 

 two days, and succeeded in taking about fifty specimens, nearly 

 all males, but one pair in coitu. From the additional material 

 we are able to make the following notes : The length varies 

 from 53 to 59 mm. The male taken in coitu and several others 

 lack the spot on the base of the dorsum of 9 ; in others it is
