No. 93. Phryg. intaminata Say mss. (Say’s determ.). May 15, 
1827; New York, Mr. Calverley. 
A female without abdomen. I believe the species identical with 
L, indivisus Walk., and very nearly related to G. fulvus Rbr.

No. 97. Phryg. elongatulus Say mss. (Say’s determ.). Cambridge, 
May 25, 1849. 
No. 98. Phryg. sericea Say var. (Say’s determ.). May 1, 1826; 
May 25-30, 1827; New York. Mr. Calverley. 
There are of No. 97 four fragments, mostly wings, one labelled 
N. H. Of No. 98 only a 6 from N. H. Say believes the last one to 
be a variety of his Ph. sericea, a still unknown species. At least, 
P. sericea must be very nearly related. Harris added to No. 98, 
‘probably Phr. dossuaria, Say,” apparently an error. The speci- 
mens No. 100, u, Phirgg. dislocata Say mss. (Say’s determ.), from 
Dublin, N. H., Mr. Leonard; and No. 105, u Phryg. debilipes Say 
mss. (Say’s determ.), same locality; are marked lost by Dr. Harris. 
A specimen without any label, apparently a late addition, is a male 
of a small species related to G. pudicus, perhaps new. 
14. Limnophilus plaga Walk. Hag. Syn., 263, 28. 
Of No. 97? are fragments of the wings (one hind wing not be- 
longing to this species) from N. H. The identification is not entirely 
sure, but very probable. 7 
15. Hallesus hostis Hag. Syn., 266, 3. 
No. 91. Phryg. subfasciata? Say. P. radiata Say (Say’s determ.), 
and a note in pencil, “probably S. interrupta Say.” June 1, 1829; 
Cambridge, June 14, 1849; July, 1849; one later addition, N. Con 
way, N. H., Aug. 10, 1853. 
Seven specimens, six only wings. 
16. Hallesus guttifer Walk. . Hag., Syn. 266, 4. 
No. 90. Phryg. subfasciata var., Say (Say’s determ.). N. H., Mr. 
Leonard. 
17. Hallesus Argus Harris Corresp., p. 333. 
No. 107. Phryganea Argus Harr. Maine, Randall, 1836. 
A female in very bad condition. This species is apparently rare ; 
T possess a female from Massachusetts, from Baron Osten Sacken, 
and saw a third specimen in the collection of the Entomological So- 
ciety in Philadelphia. It is one of the most beautiful American 
species.
