404 | DIPTERA. 
there are several small hyaline dots; there are two clear punctiform dots in the first posterior cell; the 
small cross-vein is on the middle of the discal cell. 
Hab. Muxico, Teapa in Tabasco (H. H. Smith). 
A single female specimen. 
5. Hexacheta rupta, sp.n.,?. (Tab. XI. fig. 19, wing.) 
Rufous; thorax with blackish stripes; abdomen laterally black; the brown coloration of the wings with 
irregular incisions and some hyaline dots; small cross-vein on the middle of the discal cell. 
Length 5 millim. 
Front dark rufous, as broad as the eyes, with two, anteriorly connected, brownish stripes ; ocellar tubercle and 
the frontal bristles black; face pale rufous; oral margin slightly prominent. Antenne, proboscis, and 
palpi rufous. Thoracic dorsum rufous, with three blackish stripes, which posteriorly merge into a more 
general dark coloration; pleure, scutellum, and metanotum rufous; the second pair of lateral bristles on 
the scutellum much shorter than the others. Abdomen shining rufous; second segment with a black 
front-border ; the sides of the following segments black, with rufous spots (in one of the specimens the 
black colonr is more extended); ovipositor much shorter than in the preceding species, conical, and 
flattened, the first joint shining black, the second rufous. Legs rufous; front femora inferiorly with a 
row of bristles ; hind tibize with bristly hairs on the outer side. Halteres rufous. Wings rather broad ; 
the stigma black, with a clear line along the tip of the auxiliary vein; the costa before the stigma 
alternately brown and hyaline; immediately beyond the stigma a subtriangular hyaline costal spot, not 
reaching to the third vein; in the middle of the posterior margin is a large subquadrate incision, and at 
the end of it a large triangular one, both interrupted by a few irregular brown spots; a much smaller 
incision near the end of the third posterior cell; in the first posterior cell, just above the posterior cross- 
vein, is a hyaline dot, and there are some similar dots of different sizes in the basal cells. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Three female specimens. 
_ 6. Hexacheta splendida, (Tab. XI. fig. 20, wing.) 
Blepharoneura splendida, Gig].-Tos, Mem. R. Accad. Sci. di Torino, ser. 2, xlv. (sep.) p. 58, fig. 20’. 
Hab. Mexico; Costa Rica, Rio Sucio (Rogers). 
A single male specimen of this insect has been received from Costa Rica. It agrees 
fully with the description and figure given by Giglio-los. The veins of the wings are 
distinctly spinose, as in the genus Blepharoneura, which has six bristles on the 
scutellum, in common with Hearacheta, but differs from it by the reticulated wings. 
As the wings of the present species are not reticulated, I prefer to include it in the 
genus Hexacheta.
