I am accepting as this species a female that has the wings marked 
as in Curran’s figure, but there is no subhyaline mark close against 
the posterior side of the inner cross vein, the apex of the anterior 
basal cell is more widely dark, and the brown mark on the fifth vein 
extends to the base of the discal cell. The hairs on the pleura and 
sides of the abdomen are orange-yellow, and the third vein is bare 
below.

Genus NEASPILOTA Osten Sacken 
1878. Neaspilota Osten SacKEN, Catalogue of the described Diptera of North 
America, ed. 2, p. 192. (As a subgenus of Trypeta.) 
1910. Neaspilota Coguitte7t, Proc. U. 8S. Nat. Mus., vol. 37, pp. 511, 574. (Type 
designated as Trypeta alba Loew.) 
1934. Neaspilota Bensamin, U. S. Dept. Agr. Techn. Bull. 401, p. 34. 
Benjamin, in the paper above referred to, described two species of 
the genus and gave a key to the described species that was based 
entirely upon color characters. He failed to label his species in the 
collection, and no type catalog numbers were given. I have sorted 
out his species, and numbers have herein been allotted them. 
In no paper dealing with the genus is there any mention of the 
fact that the claws of the fore tarsi of the males are asymmetrical. 
The inner or anterior claw is much larger and stronger than the 
outer one in that sex, while there is no appreciable difference in the 
claws of the female. The upper supraorbital bristle is sloped in- 
ward in all the species. 
I give below a key to the species, with added male characters that 
will augment the one given by Benjamin. The armature of the legs 
has not been previously used. 
KEY TO THE SPECIES OF NEASPILOTA 
1. Wing with several fuscous marks in addition to the one in the stigma: 
one in the marginal cell directly below the stigmal one and connecting 
with it, a more or less complete fascia from the costa before the apex 
of the second vein over the outer cross vein, a spot over the tip of 
the second vein and another over the tip of third, a cloud on the inner 
cross vein, and usually some fainter marks in the first posterior cell__ 2 
Wing with at most the stigma distinctly blackened, no dark clouds 
through or in the other cells though sometimes the cross veins may be 
darker than connecting parts of the longitudinal veins_________----- 3 
2. Hairs on the dorsum of the abdomen yellow; no distinct black mark 
on lower half of the sternopleura or on the centre of the anterior 
margin of the thorax; the fuscous mark near apex of the first posterior 
cell carried ‘entirely across thecell=_—— = a ee vernoniae (Loew)
