MAY FLIES AND MIDGES OF NEW YORK 15 



ratus and one grouse locust. Considering the abundance of 

 these about the edges of the creek, I was somewhat surprised tiiat 

 more had not been eaten. As many as this may easily have been 

 picked from the surface of the water. 



Lepidoptera. Two moth larvae only. 



Ephemeridae. A single njimph of S i p h 1 u r u s alter- 

 n a t u s Say was eaten by frog no. 14. It must have been taken 

 beneath the surface of the water as tliese nymphs do not come to 

 the surface, so far as I have observed, except to transform, and 

 this one was not ready for transformation. I have given an ac- 

 count of the habits of the nymph of this species in bulletin 47 

 p.424. It was a surprise to me that no adult May flies were eaten. 



Neuroptera. Amphibian stomachs offer a new field for collect- 

 ing representatives of this order, a field in which I have made 

 some of my ibest finds, and that in a very little material. I found 

 Sisyra umbrata Ndm. first in the stomach of a tree frog, 

 as recorded in Psyche vol.10, p.29, and these bullfrog stomachs 

 contained specimens of a new species of Micro mus, and of 

 Climacia dictyona Ndm. and Heme robins 

 amiculus Fitch, — single specimens of each. 



SYSTEMATIC NOTEiS ON HEMEROBIIDAE 



Micromus jonas sp.nov. 



Allied to M . a n g u 1 a t u s , but smaller ; expanse 10mm. 

 Known only from its wings, but these alone will distinguish it 

 (pl.3, fig.2). The fore wing is 4.7mm. long and 2mm. wide, with 

 front and hind margins nearly parallel in their middle third. 

 Their color is rich fulvous, with darker fuscous oblique streaks 

 along the line of both the gradate series, and less distinct, more 

 transverse marmorate lines between, which become arcuate where 

 they traverse the bases of the a])ical forks beyond the second 

 gradate series; hind wings pale fulvous about margins, the dis<c 

 transparent, and the veins traversing it very angulate in their 

 course with crossveins incomplete. Gradate veins in fo^'e wing; 

 inner series 5, outer series 4-.5 : in hind wing; inner series, 3-4, onter 

 series 3-4. Saranac Inn, N. Y. Taken from bullfrog stomach 

 (no.9 of table) in July, 1900.
