ODONATA 389 



single vein, of hind wings uncrossed. Internal triangle of anterior 

 wings 3-celled. On posteriors, no internal triangle. No supra-tri- 

 angular cross-veins. The single basal postcostal cross-vein is nearer 

 the base than is the first antecubital, in posteriors much nearer. 



Length with appendages, 49.7 mm.; abdomen, 34; front wing, 

 37.6; hind wing, 35.6; pterostigma, 4 ; superior appendages, 2.6. 



Type. — No. 5420, U. S. National Museum, one male collected on 

 Albemarle Island, March 23 (No. 41). 



Owing to the condition of the specimen it was impossible to de- 

 scribe the colors accurately. This species agrees remarkably well 

 with the original colored figure and description of Ca7inacria batesii 

 Kirby, but not with that author's figure of the male appendages.^ As 

 pointed out by Calvert,^ Kirby's figure represents the superior ap- 

 pendages as without an inferior tooth. This separates C. batesii., not 

 only from C. furcata, but also from the species here described. Ac- 

 cording to that figure, too, the apical outline of the inferior appendage 

 of C. batesii is unlike that of C. fufnipennis.
