TRYPANEA ERASA, new species 
Female—Head and legs dull testaceous-yellow, inner vertical, 
ocellar, and orbital bristles except the upper supraorbital yellowish 
brown, the latter and the other cephalic hairs and bristles yellowish 
white. Ocellars long, extending to bases of the upper pair of infra- 
orbitals, the infraorbitals in three pairs. 
Thorax black, humeri and pleura paler, mesonotum densely lead- 
gray dusted, without dark vittae, humeri, pleura, and scutellum 
yellowish gray dusted. The strong bristles yellowish brown, others 
and the decumbent scalelike hairs whitish yellow. 
Legs normal, yellowish testaceous including the hind coxae. Mid 
femora not bristled in front. 
Wings grayish hyaline, with very faint dark markings as in figure 
1, w, the central portion of the usual preapical star-shaped mark 
yellow, only the apices of the rays on the wing margin fuscous. 
Third vein bare or with at most one or two microscopic hairs at 
extreme base. 
Abdomen colored as mesonotum, densely gray dusted, slightly 
shiny, sheath of the ovipositor glossy black, the hairs rather long 
and whitish yellow except on apex of the sheath. 
Length, 2 mm.

As at present accepted this may be a complex of closely related 
species, but intensive field and laboratory work is required to deter- 
mine the status of specimens from different sections of the country 
and reared from different food plants. 
The wing markings vary but little in the series before me, but 
the fifth vein has sometimes no dark spot near the middle of the discal 
cell (fig. 1, 2). The frontal bristles of the male are short, and the 
mid femur of the same sex has a number of rather long bristles 
on the apical half of the anteroventral surface. 
Originally described from Texas. I have before me specimens 
from Texas, New Mexico, California, Kansas, Arkansas, Indiana, 
Georgia, Florida, and Mexico. 
Recorded food plants of the larvae are species of Hrigeron, Soli- 
dago, Aster, Coreopsis, Hieracium, and Actinospermum.
