A New Species of Celithemis. 
I S5 
monomelaena male, one wing 24, two 25, one 26, one 27; 
average 25.4. 
female, one wing 21, one 23, two 24, one 25, 
two 26; average 24.14. 
Of 8 wings of jasciata and 16 wings of monomelaena examined 
all have the last antenodal of the front wing continuous, except- 
ing one wing of each species. All have the triangle of the hind 
wing free excepting a single wing of jasciata , where it is once 
crossed. 
Celithemis monomelaena n. sp. 
Celithemis jasciata, Hine, in The Odonata of Ohio, D. S, 
Kellicott, O. S. U., Univ. Bull. Series 4, No. 5, p. 104, describes 
the species and records its capture in Summit County, Ohio, at 
Silver and Summit Lakes, in June and July, June 23rd being the 
earliest record. Hine, Ent. News, January, 1899, p. 1, des- 
cribes the female, with figures of wing markings of both sexes, and 
notes habits and records of captures. Williamson, Report 
State Geologist, Indiana, 1899, p. 320, describes the species 
and records it from the following Indiana localities: Goose 
Lake, Kosciusko County, Round and Shriner Lakes, Whitley 
County, and Frantz Fishpond, Wells County. 
The above literature, with the notes given above and the 
plates which accompany this paper, sufficiently describes this 
species. The following references under jasciata should be 
placed under monomelaena, I believe. 
1. Hagen, Psyche, 1890, p. 383, records jasciata from 
Georgia, Florida and Canada. The Canadian specimen is prob- 
ably monomelaena, the other two jasciata. 
2. Kellicott, Proc. Ohio Acad. Sci., 1896, p. 28, records the 
capture of jasciata by Dury at Cincinnati and Williamson in 
Indiana. 
3. Kellicott, The Agr. Student, Columbus, Ohio, Nov., 
1897, p. 45, repeats the data in 2. 
4. Williamson, Report State Geologist, Indiana, 1897, 
p. 404, records jasciata for Shriner Lake, Whitley County, Indi- 
ana. 
5. Williamson, Ent. News, 1899, p. 42, notes on pairing of 
jasciata at Round Lake, Whitley County, Indiana, during July, 
1898. 
6. Hine, Proc. Ohio Acad. Sci., 1899, p. 67, records 
jasciata from Silver Lake, Akron, Ohio, June 23rd. 
7. Osborn and Hine, O. S. U. (Ohio) Naturalist, 1900, 
p. 15, record the capture of about 30 specimens at lakes near 
Kent, Ohio, in the latter half of June. 
8. In Ent. News, 1902, p. 298, Mr. E. Daecke’s capture of 
jasciata at Lucaston, New Jersey, is recorded.
