SECTION C. 
Proboscis Formed for Piercing ; Metanotum with Scales 
and Chaetae. 
Sub-Family TRICHGPRQSOP0NIMA. 
Genus 20.— TRICHOPROSOPON, nov. gen. 
Head clothed with flat scales and with a ring of upright 
forked scales across the posterior half ;• antennae 14-jointed in 
the 9 ) the joints with two distinct rows of verticillate hairs, one 
long and the other short, basal lobe of the antennae bristly. Palpi 
in the 9 3-jointed, densely scaled; in the $ 4-jointed, the joints 
nearly equal, tapering, apex spinose; clypeus (Fig. 292, m.) densely 
bearded with short bristles and long ones in front; proboscis 
long, scaly, and pubescent at the rather expanded apex. Thorax 
covered with rather flat spindle-shaped scales; prothoracic lobes 
distinct, with flat scales; scutellum with dense flat spindle- 
shaped scales; metanotum with a tuft of chaetae and with flat 
scales on part of its surface (b). Abdomen covered with flat scales, 
and in the 9 with the apex very bristly; in the $ the basal 
lobes of the genitalia densely scaled. Ungues of the 9 small, 
equal and simple, in the £ those of the fore and mid legs 
unequal and simple, in the hind very small, equal and simple. 
Wings densely scaled along the veins, with rather broad flat 
scales, somewhat like those of Taeniorhynehus, but shorter; fork- 
cells rather long, the second long vein carried nearly to the base 
of the wing, the anal cell very large, and the mid cross-vein 
nearer the apex of the wing than the supernumerary cross¬ 
vein, the posterior cross-vein on a line with the mid cross-vein. 
This genus is founded primarily on the presence of nob only 
chaetae but scales on the metanotum , and the curious bearded or
