Characters. — Short robust reddish species, measuring about five millimeters in length, 
resembling the bombyliid genus Amicíus in appearance. Eyes of the male contiguous half-way 
between the antennz and the ocelli, ocellar triangle large; basal joints of the antennz nearly bare, the 
third joint long and conical, about three times as long as broad, the apical style half the length of the 
third joint, distinctly two-segmented and with short end-bristle, the basal segment about one-fourth as 
long as the apical; proboscis vertical, as long as the head, palpi curved and with a few fine hairs. 
Thoracic bristles black, no strong humeral, acrostichals short and arranged in several rows, anterior 
dorsocentrals short, hair-like and scattered, the middle ones longer and seriate, the posterior three long 
and bristle-like, notopleural bristles strong, two long and two short scutellars; pleurze bare. Abdomen 
short, pygidium small, erect and closed, middle valve large, central piece compressed below. Legs 
simple, hairs short and fine, tibiz with rather distinct extensor bristles, front metatarsi of the male 
somewhat thickened. Costa greatly thinned beyond the third vein, basal bristle present, auxiliary vein 
stopping before the costa, no stigma, fork of third vein moderately short, discal cell not large, as long 
as first basal cell, anal vein obsolete, anal angle well developed, axillary incision distinct, no alula. 
Type species: D. bicolor, Philippi. This genus was located near TAereva by Philippi.  Bezzi 
erected the genus Amictoides on Hilara (?) breviventris Philippi, stating in a footnote that it differed only 
in the structure of the antennal style. Dr. Bezzi has loaned his single specimen of breviventris, which 
has furnished the basis for the preceding description and the accompanying illustration. This specimen 
has the style exactly as described by Philippi for Deuteragonista, and agrees in all points with the rest of 
Philippi's description of the genus. Philippi separated widely the species /icolor and breviventris in his 
paper on Chilean diptera, and it may be that the two forms are entirely distinct. In the menn. 
as we have no specimens of bicolor for comparison, we have no basis for segregating the two.
