A NEW SPECIES OF LIMNEPHILIDAE FROM MAINE 
(TRICHOPTERA) 
By Nathan Banks 
Holliston, Mass. 
Hydatophylax victor sp. nov. 
In general appearance similar to Allegophylax subfasciatus. Body, 
legs, antennae, palpi mostly pale yellowish; fore wings with a large 
brown or yellowish brown area, mostly over the posterior part of 
wing, sometimes covering the basal two-thirds of the front part 
also. The apical third of the discal cell and of the cell behind it 
remains clear whitish hyaline; this is usually connected to a sim- 
ilar spot in the apical part of the thyridial cell. These clear areas 
are constant, although the amount of dark above, before, and behind 
them varies. 
There is a curved brown mark, somewhat before outer half of 
apical area, over the second and third apical cells. Sometimes the 
area beyond it is also darkened a little ; the tips of the outer veins 
are also dark. 
The surface of the fore wing is closely roughened as in Allego- 
phylax. The venation of fore wing is similar to that of Allego- 
phylax, except that the discal cell reaches almost as far back as the 
thyridial cell. In the hind wing the discal cell is also very slender 
and reaches much further basally than in Allegophylax. In the 
anal cells of the fore wing, the separation from Allegophylax is 
very distinct; the third anal cell being extremely long and slender. 
The head is scarcely as broad as in Allegophylax, but the vertex 
and ocelli about the same. The pronotum is extremely short, as in 
Allegophylax, each side with tubercles and stout bristles. 
The legs are also similar to Allegophylax, the front and middle 
tibiae spined to base, and on outer side a few spines near base. The 
hind legs are long; the tibiae spined a little before middle; the last 
joint of hind tarsus has one or two spines below. 
The male genitalia has a pair of slender processes from the lower 
base, with more slender tips, these (seen from side) reach above the 
top of the last dorsal segment; from the side one sees a short median 
projection. 
Length of fore wing: 14 to 16 mm.
