Color, almost uniform yellow, thorax and end of abdomen a shade dark- 
er than the basal segments, head considerably lighter, pale yellow. No 
orange or brown color anywhere on the body except the yellowish orarge 
ocellar crescents and a small orange spot on the extreme tip of the abdo- 
men. Eyes black by transmitted light, red by reflected. 
Head nearly half again as broad as long, considerably retracted into pro- 
thorax; cheeks slightly arched, bearing a pale short spine at about the 
middle; vertex smooth; frons depressed. Postoculars and a pair of bristles 
in front of each posterior ocellus nearly as long as the eyes, sharp!y 
curved, brown and conspicuous. A pale, slender, inconspicuous bristle at 
the inner posterior angle of each posterior ocellus, and a pair of even 
smaller bristles in front of the anterior ocellus. Eyes rather large, near- 
ly half as long as the head, not protruding, pilose, facets large. Ocelli 
large, pale, posterior pair situated a little in front of the posterior border 
of the eyes, anterior directed somewhat forward into the frontal depres- 
sion. Mouth cone long and slender, almost reaching the mesosternum. 
Maxillary palpus 3-segmented, the basal segment the longest. 
Antennae 2.5 times as long as the head. Segment 1 short, cylindrical; 
2 barrel-shaped with a wide peduncle, produced dorsally and bearing at 
the apex of the elevation two heavy bristles. These bristles are not as 
heavy as in F’. cephalica masoni and the elevation is much less marked and 
does not project over the base of segment 3; 3 widest at about two-thirds 
its length, thence tapering uniformly with nearly straight sides to a nar- 
row peduncle with several constrictions and to a broad apex. It bears a 
colorless dorsal, forked, trichome and below the base of this a pair of 
bristles which are fully as heavy and considerably longer than the corres- 
ponding ones on segment 2; 4, similar to 3 in shape but peduncle wider 
and shorter and sides not as straight. This segment also bears a forked 
trichome but on the inner side; 5 much the smallest of the intermediate
