TRYPANEA EUGENIA (van der Wulp) 
1900. Urellia eugenia vAN pDeR Wotp, Biologia Centrali-Americana, Diptera, 
vol. 2, p. 427, fig. 
This species, which is unknown to me, is described as differing 
from all others in the genus by its rufous coloration and the exten- 
sion of the black spots on the wings, thorax and abdomen grayish, 
but appearing rufous on account of a dense ochraceous dust, and 
with short yellow hairs. The wing markings are distinctive though 
of the same general type as in stigmatica and a few others not at 
that time known to van der Wulp (fig. 1, @). 
Described from Guerrero, Mexico. 
TRYPANEA STIGMATICA (Coquillett) 
1899. Urellia stigmatica CoguiLteTT, Journ. New York Ent. Soe., vol. 7, p. 266. 
This species differs from all the others contained in this paper 
except eugenia in having a short pair of apical scutellar bristles and 
the wing markings as in figure 1, 6. There is some variation in the 
extent of the two dark rays that cross the discal cell, the normal type 
being that figured but sometimes there are other fainter markings 
basally and the small mark in front of the anterior inner ray may 
be connected with the latter, with one or two minute hyaline dots in 
the disk of the large black preapical mark. 
The most remarkable variation from type is seen in a female speci- 
men from Nevada, which has a rather wide fuscous cloud from the 
anterior ray along the fifth vein to its base, and the posterior ray 
just in front of the outer cross vein ceasing at the fifth vein. There 
is a possibility that this may be a distinct species. 
Originally described from Colorado, from which State there is 
another specimen in the National Museum collection, as well as 
others from New Mexico, California, Texas, and Idaho. The Bryant 
collection contains specimens from Arizona. 
TRYPANEA AGERATAE Benjamin 
1934. Trupanea ageratae BENJAMIN, U. S. Dept. Agr. Techn. Bull. 401, p. 56, 
fig. 40. 
This species was described from a unique male, now in the col- 
lection of the National Museum (No. 54386), that was reared from a 
larva feeding in the flowers of Ageratwm littorale on No Name Key, 
Fla. Wing as in figure 1, ¢. 
TRYPANEA PERUVIANA, new species 
Male—vVery similar to eclipta in most respects, differing from it 
in having the basal segment of the fore tarsus about twice as long
