58 Psyche {April 
A single male collected by Mr. H. H. Smith at Vera Cruz, January, 
1888, from the Wheeler collection of the American Museum of Natural 
History. This specimen very likely belongs with the type female, 
which was collected in Chilpancingo in Guerrero. ‘The two locations 
are on opposite sides of Mexico. ‘The specimen is glued on a card 
and is not in the best of condition for description. ‘The type has the 
third vein nearly straight. Here it is rounded in an even curve diverg- 
ing from the fourth. This specimen has less of the purplish and 
bronze tinge to the body. 
The definition characters of Phoneutisca led us to place this species 
in that genus. An examination of the true Phoneutisca bimaculata 
in the Museum of Comparative Zoology showed it to be quite a differ- 
ent insect than was supposed. The abruptness of the marginal cell 
in Phoneutisca is very striking. 
Tachydromia calva sp. nov. 
Shining black above, paler beneath, outer half of femora blackish. An- 
tennae black, palpi slender, whitish, dorsum without evident bristles; wings 
lightly infumated, third and fourth veins sub-parallel. 
Female. Front jet black, triangular; ocelli prominent, occiput with sparse 
short black hairs; eyes deeply and broadly emarginate at antennae, face 
obliterated by the contiguity of the eyes, facets nearly uniform. Antennae 
short black, last joint not as long as broad and smaller than basal joint, the 
arista subterminal, finely and closely pubescent, nearly five times the length 
of the antenna. Palpi narrowly elongate, whitish yellow: proboscis very 
small, black. 
Thorax shining black, the humeri large, so that the thorax is nearly quadrate, 
a few microscopic dorsal bristles only, a single bristle in front of the wings, 
scutellum with a pair of short bristles, the scutellum very lightly dusted. 
Abdomen pitchy black, sub-shining. Coxae, trochanters, basal half of femora 
and the tibiae yellow, outer half of femora blackened, tarsi a little dusky; 
front femora somewhat thickened. Halteres yellow. Wings narrow, nearly 
hyaline, lightly infumated especially noticeable at tip of first vein, marginal 
cell long, third and fourth veins parallel. 
Described from a single female, presumably collected by Mr. G. R. 
Pilate as it bears the label, Tifton, Georgia, Sept. 25, 1896. The 
specimen was presented to me by Dr. G. deN. Hough. It measures 
one millimeter in length. 
Tachydromia insularis sp. nov. 
Male. Length 1.1 mm. Head and thorax pruinose; legs testaceous; 
wings clear hyaline; antennae reddish at base; palpi elongate, reddish;
