Descriptions of Dragonfly Nymphs of the Subfamily 

 Calopteryginae (Odonata). 



By James G. Needham, Cornell University, Ithaca, N. Y. 

 (Plates IV, V.) 



The basis of our present knowledge of the immature stages 

 of this group of dragonflies was laid by Dr. Hagen in a paper 

 but a few pages in length, published in 1880,* under the title 

 "Bssai d'lin Synopsis des Larvcs des Caloptcrygines." Nymphs 

 of Calopteryx had been described earlier, and in that genus 

 and in Hetaerina fuller descriptions have appeared since ; but 

 with the exception of a few undetermined forms described 

 by Karsch in 1893 j and a few figures of nymphal labia pub- 

 lished by Miss Hortense Butler in 1904, t that little paper has 

 until quite recently represented all our knowledge of the sys- 

 tematic relations of the immature stages of the group. Yet 

 that paper was merely synoptic, without other descriptions 

 than mere diagnostic statements of group characters, and it 

 was not illustrated.
