TRYPANEA MEVARNA (Walker) 
1849. Trypeta (Urellia) mevarna WALKER, List of the specimens of dipterous 
insects in the collection of the British Museum, pt. 4, p. 1025. 
1862. Trypeta solaris Lorw, Monographs of the Diptera of North America, vol. 
1, p. 84, pl. 2, fig. 19. 
1984. Trupanea mevarna BENJAMIN, U. 8S. Dept. Agr. Techn. Bull. 401, p. 54. 
Closely similar to dacetoptera, having the frontal bristles of the 
male long, the anteroventral bristles lacking on the mid femora, and 
the third wing vein with some widely separated hairs below from 
base to near inner cross vein in both sexes. The distinctions in 
both sexes are in the wing markings, particularly in the shorter 
dark fascia in front of the outer cross vein, which ceases at the fifth 
vein (fig. 1, s). 
There is a photograph of the wing of Walker’s type specimen in 
the National Museum that agrees with the wing of the species before 
me. 
It is evident from a few aberrant specimens that mevarna and 
dacetoptera are more closely related to each other than they are to 
some other species, as the complete fascia through the discal cell is 
not an infallible distinguishing character; one specimen has it com- 
plete on one wing and ceasing at the fifth vein on the other, and in 
two specimens of mevarna there is a detached dark spot on the edge 
of the wing below the abbreviated fascia. 
Walker’s type came from Florida, Loew’s type of solaris from 
Georgia. 
There are many specimens of both sexes in the National Museum 
collection from a number of localities in Florida reared from larvae 
found feeding in the flowers and tender tips of plants of the genus 
Chrysopsis. 
Records of the occurrence of this species from other localities 
should be checked to insure correct identification. 
TRYPANEA DACETOPTERA Phillips 
1923. Trypanea dacetoptera PHILLps, Journ. New York Ent. Soc., vol. 31, p. 148. 
1934. Trupanea dacetoptera BENJAMIN, U. 8. Dept. Agr. Techn. Bull. 401, p. 54, 
fig. 
This species is readily distinguished from any other in the eastern 
United States by the continuation to the hind margin of the wing 
of the outer dark ray through the discal cell (fig. 1, ¢). The wing 
markings in the sexes are similar, and there is considerable variation 
in the extent of the dark markings in front of the inner cross vein 
in the apex of the anterior basal cell, and in the form of the dark 
markings in front of the complete dark ray through the discal cell. 
In the male the frontal bristles are nearly as strong as in the 
female, the ocellars almost or quite attaining the bases of the upper
