 much extended; palpi short, four-jointed, the last joint somewhat 

 longer than the one which precedes it; antennae of the male 14- 

 jointed (fig.7); the basal joint thick, the last joint elongated and 

 thicker than the rounded preceding joints, short and sparsely 

 haired; the female with a 7-jointed antenna (fig.6), the first and 

 last joint as with the male. Eyes crescent-shaped, the concave 

 side enclosing the antennae, bare; ocelli wanting. Mesothorax 

 produced over the head, well arched ; abdomen narrow and long, 

 8-jointed, hypopygium small (figs. 10 and 11). Legs moderately 

 long, covered with fine, wooll}^ hair ; the metatarsi somewhat elon-

 small. Wings shorter than the abdomen and with the cell M^ 

 open; anal angle rounded (fig.9), Halteres free. Fries' figure 

 (copied on pl.34, fig.7) shows the male antennae with but 13 joints, 

 although the description says there are 14.
