Dianepsia. Loew, Bernstein Fauna, p. 33 (iS5o); Meunier, Mon. Mjxetoph. etc. (i5i) (1904). 
Characters. — Antennae as long or longer than the head and thorax taken together, the two 
basal joints differentiated; palpi rather short, the first joint very small, the fourth longest. Costa 
prolonged beyond the tip of the radial sector; subcosta joining the costa at about half the length of the 
basal cell R ; Sc^ (subcostal crossvein) near the apex of the subcosta; media forks beyond the base of 
the radial sector; cubitus forks proximad of the fork of the media; anal veins do not reach the margin 
of the wing (PI. 5, Fig. 13); forceps of the male robust.

Acrodicrania. Skuse, Proc. Linn. Soc. N. S. Wales (2), Vol. 3, p. 1194 (29) (1888). 
Characters. — Head ovate, fore part flattened, situated deep in the thorax; front broad, the 
anterior margin produced in a small triangle reaching to the basal joints of the antennae ; eyes oval; ocelli 
three, of unequal size, arranged in a Une on the front. Palpi prominent, incurved, four jointed, first and 
second joints robust, short, the second about twice the length of the first, third joint much more slender 
and a little longer than the second, fourth joint very slender, not the length of the second and third 
taken together; antennae cylindrical, projecting forwards, arcuated, about as long as or somewhat longer 
than the thorax, 2 -f- 14 jointed ; first joint of the scapus cj-athiform, about twice the length of the second, 
the latter cupuliform, both with short setaceous hairs at the apex; the second joint generally with onh' 
one strong seta, flagellar joints cylindrical, with very short downy pubescence. Thorax ovate, highly 
arched; scutellum nearly as wide as the thorax, too flattened to be semicircular ; metathorax highly 
arched. Abdomen rather robust, eight segments, the eighth segment very short, and generally hidden 
by the seventh; in the male flattened, claviform, with a moderate anal joint and forceps; in the female 
robust, flattened, terminating in a short ovipositor provided with two small terminal lamellae. Legs 
strong; femora broadlj^ flattened, tibiae spurred, and having strong lateral spines on the intermediate 
and hind pairs; fore tibiae with a lange of minute spines on the outer and inner side, the spines on the 
latter widely separated and few; intermediate tibife with three ranges on the outer side and one on 
the inner side; hind pair with two ranges on the outer side. Wings longer than the abdomen, moderately 
broad, with rounded off base ; microscopically pubescent. Subcosta joining the costa almost over or 
somewhat proximad of the base of the petiole of the media, united to Rj by Sca (subcostal crossvein); 
costal vein extending much beyond the tip of the radial sector, but considerably before the tip ot the 
wing; base of the radial sector is about at the middle of the wing; fork of the media is about twice as 
long as its petiole, very cuneiform, the tip of the anterior branch is as much before the apex of the v/ing
