112 THE ENTOMOLOGIST. 
simple, but emitting a very oblique rejected vein to subcosta very 
near its tip; third vein directed downward to a point just above apex 
of wing; discal cross-vein reaching discal cell very near base. Discal 
cell elongate, six-sided, having a very short face on fifth posterior 
cell, its face on first basal cell nearly twice as long as that on second 
basal, its oblique apex emitting only two veins, the first of which 
forms a wide fork, the stem of which is almost as long as its lower 
side; fifth posterior cell contracted just before apex, owing to the 
curve in the lower branch of the fifth vein (Cu), the basal corner of 
the cell only moderately produced. Sixth vein straight except at 
extreme tip, the anal cell not contracted apically; axillary vein 
straight except at extreme tip, remote from anal, running practically 
parallel with the margin. 
British Museum, I 10397. The small upper section of second 
vein was thought to be absent, but on close scrutiny it can be 
seen, obscured by an iron stain. It is present in all the living 
species, but often colourless and very faint. 
Styringomyta extensa, n. sp. 
Length about 4:5 mm., width about 1:3 mm., hyaline, faintly 
yellowish, with very pale slender veins; costa with rather long 
delicate hairs. A, running into costa at an extremely acute angle 
near middle of wing; preefurca arising a little over a third from base 
of wing, strongly curved at base, but then running a straight course 
beyond end of #,, when it separates into second (f, + 3) and third 
(A, + ;) veins, which are both simple, the second directed obliquely 
upward, forming an angle of about 45° with costa and ending far 
before wing-tip, even before level of middle of discal cell; third 
extremely long, running a slightly arched course to a point above tip 
of wing. Discal cell extremely long and slender, the base on first 
basal oblique and equal to that on second basal, the apex emitting 
three simple veins, side on second posterior short, that on third 
posterior twice as long, very oblique, and slightly arched inwards ; 
end of second basal cell oblique, taking the same direction as the end 
of first basal on discal. Sixth vein (4,) straight, diverging from fifth 
and ending far from it; seventh (axillary) gently curved at end, 
terminating a short distance beyond origin of prefurca, but before 
level of end of FR. 
Hooley Collection, 261. Differs from S. ceylonica, Edw., by 
having the axillary complete to margin, and lower side of second 
posterior cell all straight, as well as the longer discal cell. This 
is considerably larger than the styringomyia already recorded 
from Gurnet Bay, and differs in the details of the venation.
