Genus Myzomyia. 33 
exhibits bluish slate-grey stripes, the remaining parts are olive-brown, 
with a dark spot in front of the sutura transversalis. Scales rubbed off. 
Wings.—The upper fork starts beneath the commencement of the 
third marginal spot; its lower branch is about double the length of the 
lower branch of the inferior fork. The second spot of the anterior margin 
is the largest, the first and third are not much smaller, but the fourth is 
considerably smaller. The patches extend to the first vein in equal 
lengths, only beneath the second patch the darkening of the first vein 
begins somewhat later. The remaining veins are principally covered 
with dull brownish-grey scales bestrewn with a few lighter, whitish 
places; the whole extent of the fifth vein is whitish, except for a dark 
spot at the root, the fork cell and the end (marginal spot). There are 
white spots on the central cross-veins ; at the division of the two upper 
forks; on vein three there is a longish streak in front of the marginal 
point, and at the commencement of the second and fourth veins. 
The sixth vein carries dark scales on the terminal half as the central 
and marginal spots are amalgamated; it has no root spot. ‘The marginal 
points are hardly distinctive from the other scale-structure. (In photo-

graph table I., fig. 1, the root spot of the fifth vein is missing, because at 
this place it was rubbed off in the preparation.) The upper branch of the 
superior fork is somewhat darkened over its entire course, but not 
sufficiently so to contribute to the widening out of the two last spots of 
the anterior margin. 
The two inferior cross-veins are very oblique, the superior one touches 
the central one at an angle at the root of the wing, the inferior one is as 
far distant from the central one as its length. In other specimens the 
lower cross-vein is vertical ; the upper one can be either near or distant to 
the central one. 
The ciliary margin is distinctly piebald, particularly at the apex, 
which is moreover distinguished by a particularly light spot beneath the 
spot of the anterior margin. Index of the auxiliary vein, 40°8; of the 
fifth vein, 35°2; in other specimens the numbers are 40°0 and 35:3. 
Length of wings, 2°7 mm. and 2°5 mm. 
Legs have greyish-brown scales; lighter scales sparsely bestrew the 
femora and tibia; tarsi somewhat darker; jomts only slightly lighter. 
Abdomen.—The venter appears to have a dull light marking.
