It is worthy of note, that there is a cross-vein in the hyper- 

 triangular space in the left fore wing. 



Length of abdomen (excel, app.) 35 mm., appendages 25 mm., 

 hind wings 38 mm. 



Described from one female labelled Alabama in the Brooklyn 

 Institute. Holotype bearing "Accession No. 11146." 



The entire absence of anal spots on all wings will distinguish 

 this species from other Ncurocordulia. There is not the slight- 

 est trace of the anal spots as found in N. obsoleta and yamas- 

 karensis. 

 Somatochlora minor Calvert. One male, Saquenay Eiver, Prov. 



Quebec, July (Brooklyn). 

 Somatochlora cingulata Selys. One male, Saquenay Eiver, Prov. 

 Quebec, July (Brooklyn). 



The appendages of this species have never been figured. In 

 lateral view they appear almost identical with those figured by 

 Williamson for albicincta Burmeister. In dorsal view they are 

 likewise similar, except for the acute external basal spine of the 

 superior appendages.
