1955 l Carpenter — Spiloconis picticornis redescription 71 
including the type 3 , consist of 18 segments; the scape is 
about six times as long as any segment of the flagellum, 
and the pedicel is about four times as long. The proximal 
eight segments are light yellow, though the 8th is some- 
times partially gray; the next two (9th and 10th) are 
either black or dark gray; the next two (11th and 12th) 
light yellow; and the distal six (13th through 18th) black 
or nearly so. This pattern of coloration is uniform in all 
specimens which I have seen, though the intensity of pig- 
mentation in segments 9 and 10 varies somewhat. The 
maxillary and labial palps are black or nearly so on the 
outer surfaces, but lighter on the inner. The thorax and 
abdomen are pale yellow, except for the dark brown lines 
which mark the apodemes; the legs are pale yellow, but 
with some light tint of gray on the femora. The wings 
are smoky brown and lack maculations ; certain cross-veins 
and parts of some main veins are obsolescent, their posi- 
tions being indicated by white streaks in the wings. The 
venation, shown in figure 6, is typical of that of the Aleu- 
ropteryginae ; I have seen no obvious variations in the 
venational pattern of either wing. The pattern is like that 
of sexguttata, except that the bases of the macrotrichia 
are more conspicuous and are proximal to the middle of 
the wing. 
The terminal abdominal segments of picticornis differ 
greatly from those of the species of the Coniopteryginae 
and Aleuropteryx. Since I have had no opportunity to 
make a comparative study of the terminalia of other species 
of Spiloconis, I am unable to indicate which characteristics 
are generic and which are specific. The most striking pe- 
culiarity of the male abdomen is the reduction of the 
ninth tergite and sternite. Although the sclerotization of 
the abdomen is weak, the first eight segments are readily 
distinguished, each bearing a pair of spiracles; segments 
3-6 also have the evaginable sacs peculiar to the Aleurop- 
teryginae. The tenth tergite is distinct but the ninth ap- 
pears to be fused with the eighth, presumably bearing 
3 Banks’ statement that there are 20 antennal segments in the type was 
apparently an error. His description of the color pattern was also in- 
correct, probably as a result of his mistake in counting the segments.
