Leptophlebia assimilis n. sp. PI. XXVIII, fig. 8. 



Very close to L. prcepedita, but in male the basal joints of forceps: 

 seen from below are widely divergent, and this basal piece does not 

 extend so far out below the next piece as in L. pnepedita (in L. 

 prcepedita the basal pieces seen from beneath are close together). 

 Marked much as L. prcepedita, but no trace of color in the costal 

 area of wings, middle segments of the abdomen bordered behind with 

 dark, ventral segments with a blotch on each side. Leg I of male 

 with about same proportions as in L. prcBpedita, but whole leg shorter; 

 no costals in apical part of wing crossed. Expanse 14 mm. 



From Black Mt., north fork Swannanoa River, N. C, May. 



Ephemerella vernalis n. sp. PI. XXVIII, fig. 11. 



(^. Size and appearance of E. excrucians, but in leg I of cf the 

 tarsi are fully one-fourth longer, the third joint being over three- 

 fourths as long as second (in E. excrucians much shorter). Markings 

 of body, legs and setae as in E. excrucians, venter shows no marks, 

 the last two segments being dark. Venation about the same, the 

 costals in apical part are crossed. In. the male forceps the next to 

 last joint is plainly swollen. Expanse 22 mm.

cf . Head and thorax dark brown; abdomen dark on base and 

 tip, segments 3 to 6 each with a very large median triangular pale 

 mark occupying most of these segments, segment 7 with a pale basal 

 band. Venter mostly pale, dark at base and tip; setse white, legs 

 whitish, femur I nearly black, tip of tibia I dark; in tarsus I the 

 first joint is nearly one-half of the tibia, second joint almost as long 

 as first, third fully one-half of second ; mid and hind legs very slender. 

 Wings hyaline, unmarked, veins pale, indistinct, five costals in the 

 swollen apical part; hind wings about twice as long as broad, angu- 

 late on the middle of costa. Expanse 10 mm.
