FAM. EMPIDID/E 3o1 
I3. GENUS MEGAGRAPHA, NOV. GEN. 
Gharacters. — Small, stout, pubescent species with broad wings and large basal cells. Head 
globular, the occiput hemispherical, densely hairy above; eyes nearly contiguous above and beneath 
the antennz, separating at the ocelli which are placed up toward the vertex and have small ocellar 
bristles, on the face the eyes broadly round away about one-third the distance from the antennz, cheeks 
linear, pubescence of the eyes dense, facets uniform, hind margin of the eye S-shaped, excision at the 
antenne small. Proboscis vertical, one-half the head-height, not thickened at the base, the palpi broadly 
oval, shorter than the proboscis, pubescent but without apical bristles. Antenne three-jointed, without 
bristles, the third joint lanceolate, but flat above, densely pubescent, the arista terminal, shorter than the 
antenne, without basal segment, thick with close pubescence. "Thorax broadly quadrate, humeri not 
swollen, densely and uniformly pubescent, the hairs obliquely reclinate, no discal bristles, no humeral, 
about six short notopleural bristles in a prealar series diminishing in size toward the front, one pair of 
widely separated prescutellar dorsocentrals, scutellum large, rounded triangular, flat above, with close 
short pubescence above and below and with six marginal bristles; pleurz bare except for a velvety patch 
of tomentum on the metapleurz before the halteres. Abdomen short and broadly conical, comprising 
seven segments and the lengthened ovipositor which latter terminates in two slender styles, basal ventral 
segments not chitinized, abdomen hairy especially toward the end, the first segment not broadly swollen 
at the sides as is usually the case in the pale-colored species of Drafetis. | Legs slender and short, without 
bristles but with abundant hairs, no tibial spurs, the hind tibiz seriately spinulose on the extensor side, 
last tarsal joint small, pulvilli minute. Wings broad, the anal angle broadly rounded, costa not swollen, 
first vein ending at the middle of the wing, pedicel of the second and third veins long, basal cells large 
and of the same length, anal crossvein wanting, but the anal vein present close to the hind margin, no 
costal bristles but the marginal cilia longer toward the root of the wing. 
Type species : M. (Drafetis) Pubesceus, Loew, the only species so far known. 1 know of but 
four specimens of this species, all females, from Georgia, New York and Massachusetts.
