elongated C with the open side slightly south of east, the 

 maximum length in a straight line being about 40 miles. 

 Grand Entry, where Dr. Atkinson collected, is at the terminus 

 of the upper curve of the C- 

 (i.) Enallagmahageni Walsh. 



Grand Entry, June 30, 1901, 41 S . This species ranges ap- 

 proximately between 40° and 47° N. Lat. and 60 and 100° W. 

 Long. Specimens from Grand Entry average larger than 

 Indiana and Ohio specimens. 



(2.) Enallagma cyatUgeram Charp. 



Grand Entry, June 23, 1901, 5 ^; June 30, 14 S. This 

 species, with its races, is known from Northern Asia, Europe 

 and North America. How definitely the races may be recog- 

 nized I do not know. Hageni, cyathigcrum and calverti are 

 a group of very closely allied species. In North American an- 

 ncxum, as identified by authors, occurs with hageni and cal- 

 verti in Maine and Massachusetts. Calverti appears east of the 

 Great Plains in one other State, Indiana, in which hageni has 

 also been taken. Annex nvi and hageni are reported for New 

 Hampshire. Hageni has not been taken west of the Great 

 Plains. Calverti and annexum are reported for Washington 

 and Wyoming. Annexum is also recorded for California. In 

 North America north of Lat. 45° annexum has been reported 

 generally, calverti only in the extreme west, while hageni is 

 known only from Quebec. It may be that annexum and calverti 

 have been confused by earlier authors. Twenty-two female 

 Enallagmas, not specifically determined, were taken at Grand 

 Entry, June 30. 



(3) Agrion resolutum Hagen. 



Grand Entry, June 23, 1901, 4 $\ June 30, 34 S , 11 9. 

 This species has hitherto been reported from Canada west of 

 Long. 95°. Specimens from Magdalen Islands amply illus- 

 trate, as variations, the different points in Hagen' s description 

 of the form servum from Fort Resolution (Selys Syn. des 

 Agr. Le Grand Genre Agrion, p. 1264 or 154). Of the 

 differences pointed out by Selys between resobdum and the 

 European A. hastu latum, the coloration of the rear of the head 

 and the shape of the hind lobe of the prothorax seem most
