This is a well-defiued species and, as indicated by Bergroth, related 
to the Nearctic L. lateipemiis, et al. ; the bright yellow colour of the 
first flagellar segment of the antennae is a conspicuous character. 
The male specimen offers the following measurements : Length 85 mm. ; 
wing 8-8-4 mm. The venation is shown on Plate XI, fig. 20. 
? LiMNOPHILA DUBIOSA, Sp. n. 
Antennae of the male elongated, the flagellum bicolorous ; wings 
with a heavy brown pattern, with about seven larger blotches along 
the costal margin ; cell M^ absent ; a strong supernumerary cross-vein 
in cell M. 
Male. — Length 65 mm. ; wing 74 mm. 
Rostrum and palpi black. Antennae very elongate, but six flagellar 
segments remain and the entire organ must be nearly as long as the 
wing ; scape dark brown ; flagellar segments with the basal half 
brownish-black, the apical half dull yellow; scapal segments large, 
the first segment elongate, the second segment very short, much 
broader than long ; flagellar segments abruptly narrower than the 
scape, elongate-cylindrical, without bristles, but with abundant 
elongate pale outstretched hairs. Eyes small with coarse ommatidia ; 
space between the eyes very broad. Head discoloured, dark brown. 
Thorax dull dark brown, any ])loom destroyed by discoloration of 
the type. Pleura dark brown. Halteres elongate, dull brownish- 
yellow, the knobs brownish. Legs with the coxae and trochanters dark 
brown ; remainder of the legs broken. Wings pale yellowish-white 
with a heavy brown pattern, consisting of about seven larger dark brown 
blotches along the costa, the first at the wing-base, the third at the 
origin of the sector, the fourth at the tip of Sr-^, the fifth, largest, at 
the tip of jR|, the sixth at the tip of Be, ; the remainder of the wing 
is densely spotted and clouded with a paler shade of brown ; veins 
dark brown, in the paler areas more yellowish. Venation, Sc rather 
short, ending just before the fork of Es ; Sc, at the tip of Sc■^ ; Bs 
elongate, arcuated at its origin; B.,-{-.^ rather long, almost in aline 
with Bs ; Be, and B.^ divergent, widely separated at the wing- margin ; 
basal deflection of B^ + - nearer the base of the wings than the r-m 
cross-vein ; cell M^ absent ; basal deflection of Cu-^ under the middle 
of cell 1st Mo ; a strong supernumerary cross-vein in cell M, this vein 
slightly subsinuate in its course. 
Abdomen dark brown, discoloured.
