A New Species of Habrophlebia* 



By Nathan Banks. 

 Habrophlebia is a genus of Mayflies described by Eaton in 

 1 88 1. Ths species have three setae in both sexes, and differ 

 from the allied Ephemerella, Leptophlebia and Blasturus in 

 having the hind-wings angulate on the costal margin, and 

 the fore-wings without the short marginal veins. The hind- 

 wings are much narrower and with fewer cross-veins than in 

 Ephemerella. In the male the eyes are enlarged and divided 

 as in the allied genera ; the eyes of the female are widely sepa- 

 rate. The costal cross- veins are few and indistinct.

The genus is well represented in Europe, and Eaton in his 

 Revisional Monograph says he has seen an undescribed species 

 from New Hampshire. The one species known to me may be 

 called : 



Habrophlebia americana n. sp. 



It is dark brown in color, mottled with pale on the sides of the thorax 

 and abdomen ; lower part of male eyes dark, upper part pale ; legs pale, 

 anterior femora darker, especially at tip ; hind femora with a dark band 

 near tip, and a less distinct one near the middle. Wings hyaline ; vena- 

 tion pale brown. Fore wings rather narrow ; no costal cross veins before 

 the bulla ; no short marginal veins ; intercalary veins not branched. 

 Hind wings with the costal margin strongly angulate in the middle ; few 

 costal cross-veins. Three subequal, annulated setse, longer than the 

 body ; posterior tarsi four-jointed ; male claspers pale, three-jointed. 



Length, 5 mill.; expanse, 11 mm. 



Received from Mr. Edw. Berry, of Passaic, New Jersey, 

 who bred it, and has published a description of the nymph in 

 the Avierica7i Naturalist, 1903, page 26.
