412 DIPTERA. 
beyond the middle of the face; arista black, pubescent. Proboscis and palpi rufous. Thorax, scutellum, 
and metanotum rufous; thoracic dorsum with yellow pilosity, at the posterior margin with two brown 
spots; metanotum also with two brown spots, which are sometimes prolonged to stripes; the bristles on 
the sides of the thorax black, some yellow ones above the coxe only ; scutellum with six black bristles. 
Abdomen rufous; on the second and each of the following segments a row of four black dots and laterally 
a black stripe or hind-border ; these markings often indistinctly separated from the more fuscous ground- 
colour (perhaps in consequence of exsiccation). Ovipositor of the female flattened, its first joint shining 
black, the second rufous, lanceolate. Legs pale rufous. Halteres yellow. Wings longer than the 
abdomen, rather broad; the costal cell with alternate brown and clear spots; stigma blackish-brown, 
with a clear line along the end of the auxiliary vein and a white dot at the tip; immediately beyond the 
stigma a subtrigonal hyaline costal spot, reaching the third vein ; round the tip of the wings a row of hy aline 
dots, and at the posterior margin a very large hyaline spot, formed by an aggregation of several dots , 
there are also some isolated white dots in the centre. The first, third, and fifth veins are beset with short 
bristles; the small cross-vein is on the middle of the discal cell. 
Hab. Mexico, Tepetlapa 3000 feet, Chilpancingo 4600 feet, Xucumanatlan 7000 feet, 
all in Guerrero, Vera Cruz, and Teapa in Tabasco (H. H. Smith). 
Several examples of both sexes. The above-described pattern of the wings (fig. 5) 
is that of the majority of the specimens. The stigma rarely shows a trace of a second 
clear dot; and the large hyaline spot on the posterior margin is often reduced to some 
isolated and irregular spots. One of the most aberrant forms is represented on Tab. XIT. 
fig. 5a. This latter figure very much resembles that of B. saga, Gigl.-Tos [Mem. R. 
Accad. Sci. di Torino, ser. 2, xlv. (sep.) p. 56, fig. 19}; but the description of the author 
1s not quite applicable to the insect before me. 
2. Blepharoneura femoralis, sp.n.,¢ 9. (Tab. XII. fig. 6, wing.) 
Rufous; the stripes on the thorax, the spots on the pleuree and abdomen, and the tips of the hind femora, 
black ; wings with large, partly coalescent, hyaline spots. 
Length 5°25 millim. . 
Very like the preceding species (B. fulvicollis), but differing from it in the black markings of the thorax, the 
black tip to the hind femora, and the coloration of the wings. Thoracic dorsum with four black stripes, 
which are interrupted at the transverse suture ; some black spots on the pleure ; the breast wholly black ; 
two spots on the scutellum and two stripes on the metanotum. On the sides of the thorax several rather 
stout, black bristles; scutellum with six bristles. The second and each of the following abdominal 
segments with a pair of black dorsal spots and a black lateral stripe ; sometimes the black coloration of 
the abdomen is more extended and leaves only some regular rufous markings. Ovipositor of the female 
as in B. fulvicollis. Legs rufous; the tips of the hind femora black. Halteres yellow. On the wings 
most of the hyaline marks are large and coalescent; stigma with a white spot and a clear line at the end 
of the auxiliary vein; immediately beyond the stigma a large hyaline costal spot, reaching to the first 
posterior cell, sometimes showing a tendency to be divided in two; opposite to this spot there is on the 
posterior margin a much larger, subquadrate, hyaline spot, which fills the greater part of the discal cell ; 
in the apical portion of the wings are several nearly coalescent hyaline spots; there are also in the basal 
part and in the centre of the wing some isolated smaller spots. The first, third, and fourth veins bristly ; 
the small cross-vein on the middle of the discal cell. 
Hab. Mexico, Sierra de las Aguas Escondidas and Omilteme, both in Guerrero 
7000 to 8000 feet (H. H. Smith). | 
Several specimens of each sex.
