TEPHRITIS. 431 
fuscous, not very obscure reticulation; the base, to a little beyond the inferior basal cells, hyaline; the 
stigma yellowish, with the tip only fuscous: beyond the stigma there is a large subquadrate, hyaline 
spot, reaching tc the fourth vein, and interrupted by some narrow cross-stripes ; it includes the small 
cross-vein, which is not at all bordered with fuscous ; the posterior cross-vein, on the contrary, is wholly 
covered by the fuscous coloration: in the first basal cell, the discal cell, and the apical portion of the 
wings are several hyaline dots of different sizes, one of them being at the tip between the third and fourth 
veins ; there are also some very large hyaline dots at the hind margin. 
Hab. Mexico, Amula, Xucumanatlan, and Omilteme, 6000 to 8000 feet, all in 
Guerrero (H. H. Smith). 
Two males and two females. 
5. Tephritis fibulata, sp.n.,¢ ¢@. (Tab. XII. fig. 26, wing.) 
€inereous ; head and legs rufous ; femora, except at the tip, black ; the fuscous reticulation of the wings not 
covering the small cross-vein ; stigma with a white dot; a hyaline apical dot between the third and 
fourth veins. 
Length 2°5 millim. 
Head rufous; front a little broader than the eyes, with parallel sides and whitish orbits; frontal bristles 
black ; face excavated; oral margin slightly prominent ; cheeks rather broad, yellowish-white. Antenne 
rufous, reaching to near the oral margin. Proboscis and palpi rufous. Thorax, scutellum, metanotum, 
and abdomen cinereous; thoracic dorsum sometimes with three indistinct dark stripes and with yellowish 
hairs ; the sides of the thorax with black bristles ; scutellum with four bristles ; abdomen elliptical, each 
segment with two brown spots, which, however, are often inconspicuous ; ovipositor of the female shining 
black, as long as the last three segments together. Coxe and femora black; the tips of the femora, the 
tibie, and the tarsi rufous. Halteres rufous. Wings elongate; the stigma blackish, with a white dot ; 
the fuscous reticulation limited to three spots, one adherent to the stigma, the second along the posterior 
cross-vein, and the third in the apical region; the spot on the stigma reaches the fourth vein, and is 
perforated by two hyaline dots in the cubital cell and two others in the first basal cell; beyond the 
stigma is a large hyaline portion, in the middle of which is the slightly thickened small cross-vein, without 
any fuscous border; the fuscous apical portion of the wings is interrupted by some large hyaline dots 
along the margin (one between the costa and the second vein, two between the second and third veins, 
and one at the extreme tip between the third and fourth veins), and by several smaller dots placed more 
inwards ; the base and nearly the whole posterior margin of the wings are hyaline, with some small fuscous 
stripes and spots representing fragments of reticulation; on the inner side of the posterior cross-vein are 
two small clear dots. 
Hab. Mexico, Orizaba (H. H. Smith & PL. D. Godman). 
Four specimens. 
6. Tephritis obsoleta, sp.n.,?. (Tab. XII. fig. 27, wing.) 
Cinereous ; head and legs rufous; the fuscous reticulation of the wings not covering the small cross-vein; 
stigma without a white dot; a hyaline apical spot between the third and fourth veins. 
Length 2°5 millim. 
Closely allied to the preceding species (7. fibulata), but without a white dot in the stigma, and also differing 
in the colour of the femora, which are not black. The thoracic dorsum shows no trace of stripes; the 
abdomen is brownish-cinereous, and the spots on it are indistinct ; the ovipositor is shorter, as long as 
the last two segments ; the legs, including the coxe, are rufous; the knees of the middle pair have a 
whitish reflection. The pattern of the wings is nearly the same as in 7. fibulata: in the middle of the 
costa is a quadrate fuscous spot (which in 7’. fibulata is represented by a narrow cross-stripe only); the
