KELLICOTT. 81 



BASLESCHNA, Selys. 



The single species of this genus is abundant at 

 times, while some seasons pass without its being ob- 

 served at all. It is on the wing early, specimens having 

 been procured at Columbus as early as the middle of 

 April. 



Basiasschna Janata, Say. 



Length : of abdomen c? 9 43, hind wing cT 9 36. 



Colors; brown and fuscous. Male; front greenish, 

 above yellow or greenish, with a median, longitudinal, 

 impressed, black marking; occiput and rear of eyes 

 largely yellowish. Thorax, mid-dorsal carina fuscous 

 bordered each side by greenish; two greenish yellow 

 bands edged with fuscous on each side ; wings clouded 

 at base, veins brown, pterostigma yellow, membranule 

 white. Abdomen constricted at 3, superior append- 

 ages as long as 9 + 10, narrow at base, very gradually 

 widening to beyond the middle. Here there is a bend 

 and the general direction is directly backward, instead 

 of obliquely downward and backwards as before. The 

 apical third is flattened. Inferior appendages conical, 

 one half as long as the superiors. 



The female appendages are shorter, straight, and 

 anal angle of hind wing rounded. 



EPLESCHNA, Selys. 



Like the two preceeding genera this one contains 

 only a single species. It is the bulkiest dragonfly of our 

 fauna. Macromia taeniolata approaches it in expanse 

 but not in size of body. This species differs from other 

 species of the sub-family in the less obvious constriction 

 at abdominal segment three. 



Epiasschna heros, Fab. 



Length : of abdomen cT 65 9 67, hind wing c? 55 9
