LIMNOPHORA. 325 
anteriorly somewhat cinereous, with traces of black stripes; abdomen elliptical, with some cinereous 
tomentum and four black spots—two on the second and two on the third segment; long macrochete 
and bristly hairs at the hind margin of the third segment and on the anal segment. Legs slender, black, 
the extreme tip of the front femora rufous, the hind tibie piceous; front femora with a row of bristles 
on the upper and under sides; foot-claws and pulvilli elongate, the pulvilli yellowish. Tegulee and 
halteres yellowish. Wings brownish, darker along the costa; a very minute hyaline spot at the base of 
the mediastinal cell; small cross-vein under the end of the first vein and beyond the middle of the discal 
cell; terminal section of the fourth vein longer than the penultimate section (3:2); posterior cross-vein 
oblique and nearly straight. 
flab. Mexico, Sierra de las Aguas Escondidas in Guerrero 9500 feet (H. H. Smith). 
A single male specimen. 
_ 2. Limnophora meraca, sp. n., 3. 
Cinereous; head white; eyes separated by a narrow front; antenne, palpi, four spots on the abdomen, and 
legs, black. 
Length 5 millim. 
Front in the middle narrow, slightly separating the eyes, triangularly enlarged above the antenne; frontal 
band black; the internal orbits white; face and cheeks white, with blackish reflections; oral margin 
retracted ; inferior part of the cheeks very narrow, with the usual row of bristles. Antenne black (in 
the unique specimen somewhat compressed in the antennal grooves); arista pubescent. Proboscis and 
palpi black; the palpi cylindrical, with short bristly hairs. Thorax, scutellum, and abdomen cinereous ; 
thorax with indistinct brown stripes; abdomen elliptical, with four brownish-black spots—two on the 
second and two on the third segment, and with many bristly hairs arising from black points. Legs 
black ; front femora with a row of rather long bristles on the underside; foot-claws and pulvilli scarcely 
elongate, the pulvilli yellowish. Tegule whitish; halteres yellow. Wings greyish-hyaline; small cross- 
vein under the end of the first vein and a little beyond the middle of the discal cell; third and fourth 
veins parallel; terminal section of the fourth vein twice as long as the penultimate section; posterior 
cross-vein oblique and straight, nearly equalling in length the terminal section of the fifth vein. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
A single male specimen. 
8. Limnophora delecta, sp. n., ¢ 9. 
Cinereous; head white; eyes contiguous (¢); four spots on the abdomen, antenne, palpi, and legs, black ; 
fourth vein slightly curved upwards at the tip. 
Length 5 millim. 
Very nearly allied to LZ. meraca, but differing from it in having the eyes quite contiguous in the male, and the 
spots on the abdomen more quadrangular, with a slight projection anteriorly on the inner side. The knees 
are rufous. The third and fourth veins are not exactly parallel, the latter being a little curved upwards 
at the end; the posterior cross-vein has a more perpendicular position and comes inferiorly nearer to the 
border of the wing, thus making the terminal section of the fifth vein much shorter than the cross- 
vein. The antenne are inserted on the median line of the eyes; the third joint is double as long as the 
second. In the female the front is as broad as the eyes and has parallel sides, the frontal band is repre- 
sented by two black stripes, which are convergent towards the antenne, the blackish stripes on the 
thorax are more conspicuous, and the abdomen is ovate, pointed at the tip, with the four spots on the 
median segments less distinct; the neuration of the wings agrees with that of the male, the curvature at 
the end of the fourth vein is, however, scarcely perceptible. 
Hab. Mexico, Amula 6000 feet and Rincon 2800 feet, both in Guerrero 
(H. H. Smith). 
A male specimen from Amula, and a female from Rincon.
