interval in second basal cell, the second around the origin of the 
preefurca, and the third around the basal part of the first submarginal 
cell and extending in more diffused form to end of prefurca; the 
apex, region of discal cell and below it, and practically the whole of 
second basal and anal cells except a light interval towards the base 
strongly dusky; the lightest areas of the wing (appearing con- 
spicuously whitish) are about the middle of the preefurca and the 
middle of the submarginal cells. 
British Museum, I 9213. In having end of second basal beyond 
middle of discal cell this resembles L. noveanglie, Alex., and 
L. irrorata, Johns. In having marginal cross-vein nearly at end 
of Ry; it resembles L. lutea, Doane. It is easily recognised by the 
beautifully spotted wings. 
Dicranomyta wndulata, a, sp. 
Wing hyaline and immaculate, with fuscous veins, elongate, the 
apex being rather acutely rounded ; length about 6 mm., width 2 mm. 
Auxiliary vein ending acutely on the costa very slightly before its 
middle, just before the origin of the preefurca. A, ending in a similar 
manner at level of discal cross-vein. The strongly-arched prefurca 
is given off from F at about the middle of the wing slightly beyond 
the level of the end of the auxiliary vein, and after a short course 
divides. into the second and third veins, the fork being broad at base. 
Two marginal cells, divided by a very oblique vein directed backward 
from the second vein; the second marginal somewhat longer than 
the first. The third vein terminates at exact tip of wing, being 
curved somewhat downward before its end. Discal cross-vein 
present, somewhat oblique, reaching the fourth vein near its separa- 
tion from the fifth, the fourth (JZ) and fifth (Cw) being connected 
for a short distance by anastomosis. The lower branch of the fifth 
runs out with a slight curve to the border. The sixth vein is 
straight, seventh vein with a double curve, the second very strong. 
The anal angle is well marked. The fourth vein is forked less than 
half way between the discal cross-vein and the apex of the wing, the 
fork broad. The first basal is longer than the second by the breadth 
of the apex of the second. 
British Museum, I 9146. A peculiar species, remarkable for 
the open discal cell and short second basal. The absence of the 
vein separating discal cell from third posterior is very unusual 
in the genus, but Osten Sacken found this character in some 
specimens of D. pubipennis. 
Dicranomyia excavata, ni. sp. 
d. Length of body about 5 mm., ferruginous; wing 5°‘7 mm. 
long, 1:3 mm. wide, tinged with ferruginous, especially in the apical 
region ; veins pale, ferruginous, f, ending about 1:3 mm. from tip of 
wing, Origin of preefurca not visible, owing to loss of a portion of the 
middle of the wing, but from the direction the visible part takes it is 
far beyond middle of wing, apparently about 2 mm. from apex ; it is 
very short, soon dividing into the second (R, + 3) and third (A, + 5)
