NOTES ON SOME NEW ENGLAND PHRYGANEIDAE 
(TRICHOPTERA) 1 
By Nathan Banks 
Holliston, Mass. 
Among the caddice flies taken by Prof. Brues at Peters- 
ham, Mass., and also by the State Forest Service in Maine, 
there are many specimens of Banksiola. More than half are 
selina , but many are dossuaria, and there are (from Peters- 
ham) six specimens of smithi (both sexes) and two males 
and two females of cava, previously known to me by only 
one specimen. Also from various localities there are many 
canadensis and some of the similar (in appearance) Neu- 
roma angustipennis. 
In B. selina I note that there is much variation in the 
processes on the hind margin of the genital cavity, and fre- 
quently the two sides are unlike. 
Of the dossuaria six are from Petersham, the others from 
Maine; Tim Pond, Holeb, Ashland, Hardwood Mt., Oquos- 
soc, Camp Colby, Round Mt., Seeboomook. 
The smithi are all from Petersham, except one from Hol- 
liston. Leonard has recorded B. smithi from Michigan. The 
canadensis are mostly from Ashland and Gibson, one Tram- 
way, Jonesboro, and Kellyland. (These are the ones pinned, 
others were put in alcohol, and many more discarded, mostly 
selina.) 
In the M.C.Z. collection there is a new species of Banksiola 
from eastern Massachusetts, noticeable for its four sub- 
equal horns.
