TWO GENERA OF TRYPETIDAE—MALLOCH i) 
as thick, with some downwardly directed dark hairs at base of the 
ventral surface that are longer than the diameter of the segment, 
less evident hairs on the anterior side of the intermediate segments, 
the fore tibia more swollen and with the dorsal series of erect hairs 
more distinct and decidedly stronger. There are no outstanding 
bristles on the anterior surface of the mid femur. The wing pattern 
differs also in having only a yellow suffusion in the stigma and no 
appreciable cloud on the inner cross vein (fig. 1, @).

The male of this species has the fore tarsus shorter and stouter 
than in the other species except the two immediately above, with 
fine outstanding hairs on the anterior edge of the second to fourth 
segments, some of them distinctly longer than the width of the 
segments, the basal segment thickened and but little longer than 
wide, with a tuft of stiff yellow hairs on the underside at apex that 
projects forward against the ventral surface of the second segment. 
The fore femora in all three species of this group are thickened 
and have a few very short posteroventral bristles on the apical half, 
while the mid femur lacks the anteroventral bristles and has the 
anterior central series almost undeveloped. 
In a few specimens there are one or two microscopic hairs on the 
third wing vein below about midway between the base and the inner 
cross vein, and in more there are one or two hairs at base below 
that are sometimes yellow. 
Wing markings usually as shown in figure 1, e, a dark fascia near 
apex of the discal cell, but sometimes this is reduced to a mere spur 
against the fourth vein. In a few specimens there are a number of 
minute hyaline dots in the large black preapical mark, and in no 
case is the dark discal mark connected with the latter by a diagonal 
ray.

Holotype, allotype, and 178 paratypes, U.S.N.M. No. 54383. Ben- 
jamin states that he had, besides the holotype and allotype, 170 
paratypes, but there are 178 in the collection.
