ACROTANIA. 415 
Abdomen brown, with narrow yellowish hind-borders to the segments. Legs ochraceous; front femora 
with a row of yellow bristles on the upper and under sides ; first joint of the front tarsi longer than the 
following joints together, enlarged and black in its apical half; the last joint also black. Halteres 
yellow. Wings broad ; the surface up to the posterior cross-vein, with the exception of the base, costa, 
and hind margin, brown, with numerous very small hyaline dots in regular rows; at the middle of the 
costa is a double row of black spots, and beyond the last spot of the upper row is a hyaline incision not 
passing the second vein; the apical third of the wings is yellow, with five incisions—two between 
the second and third veins, one at the tip of the first posterior cell, and two larger ones in the second 
posterior cell; there is a hyaline oblong spot between the second and fourth veins ; the yellow colour is 
slightly infuscated where it touches the margin; the posterior margin of the wings is also infuscated, 
with three hyaline semicircular incisions; the small cross-vein is distinctly beyond the middle of the 
discal cell and bordered with blackish-brown. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
A single male specimen. 
2. Acrotenia apiata, sp.n.,¢ 2. (Tab. XII. fig. 12, wing.) 
Rufous; wings fuscous, with numerous clear dots, the basal and apical portions yellowish, the tip and the 
hind margin with hyaline incisions; tarsi not enlarged. 
Length 3:5 millim. 
In general shape and coloration agreeing with the preceding (A. tarsata), but differing in the coloration of the 
wings. The front is a little more attenuated anteriorly ; the antenne are longer and reach to near the 
oral margin; the abdomen is rufous, with brownish front-borders to the segments; the ovipositor of 
the female is shining brown, flattened; the fore tarsi are not enlarged. The wings are without black 
costal spots ; the stigma only is blackish-brown, with two clear dots; the base, including the second and 
third basal cells, is yellowish ; the rest of the surface, the tip excepted, fuscous, with clear dots, mostly 
in longitudinal rows ; the dots are larger but less numerous than in A. tarsata, especially towards the 
hind margin, where the coloration is less intense; the tips of the wings are yellow, with four semicircular 
hyaline incisions; there is a row of similar incisions along the hind margin. 
Hab. Mexico, Chilpancingo 4600 feet, and Amula 6000 feet, both in Guerrero 
(H. H. Smith). 
One male and one female. 
3. Acrotenia incisa, sp.n., ¢ 9. (Lab. XII. fig. 13, wing.) 
Rufous ; wings fuscous, with clear dots, the tips yellow, with hyaline incisions ; the base, a large incision at 
the hind margin and some smaller incisions at the costa, hyaline ; stigma without clear dots. 
Length 5 millim. 
Closely allied to the preceding (1. apiata), but differing again in the coloration of the wings: near the hind 
margin is a large hyaline trapezoidal spot, encroaching on the median portion of the discal cell; the clear 
dots are in the stigma; there is a hyaline costal spot before the stigma, and a similar spot immediately 
beyond it; the clear dots on the fuscous surface are less regularly arranged than in the two preceding 
species. The front is broader than the eyes, not longer than the face ; anteriorly it has on each side, close 
to the base of the antenne, a black point, which is absent in A. apeata; the antenne are shorter than in 
that species ; the abdomen is brownish-yellow, with the front-borders of the segments a little more obscure. 
Hab. Mexico, Omilteme in Guerrero 8000) feet (H. H. Smith). 
Several specimens, including both sexes.
