Race HuDsoNicA, Hag. 



Calopteryx hudsonica^ Hag. 187^ 

 Selys, 4 Add. p. 7, 6 bis. 



I have before me only one male, end of 

 abdomen wanting, and two females, 

 one of them a fragment. All are col- 

 lected bv Mr. Barnston at Michipicoten 

 Lake Superior, northern shore. 



Until now I have not seen good and 

 sufficient specimens of C. aeqitahilis. 

 I am now of the opinion that C. 

 hudsonica is not specificallv different 

 from C. aequabilis. There are some 

 characters, which may be striking 

 enough to allow it to be considered as 

 a peculiar race. First, it is visiblv 

 stronger and more bulky in the thorax, 

 head and abdomen. The dimensions 

 are not larger than the largest ones 

 noted for C. aeqiiabilt's. The male 

 has the legs pale, which mav be 

 due to a lack of development, as I 

 do not find pale le;j;s in a yoiuiger male 

 from Norwav, Me. The wings are a 

 little stronger tinged ; antecubitals 33. 

 The females are older, the colors more 

 finished. More specimens are needed 

 before a satisfactory conclusion can be 

 reached. The female, described from 

 Hudsons Bay, is similar. Perhaps the 

 C. virgo from Greenland mentioned
