ferred to Spiloconis Hagen’s cerata from Ceylon, originally 
assigned to Coniopteryx 2 Up to the present time, there- 
fore, the genus has been known from Australia and five 
islands in the Asiatic region. The specimens of picticornis 
from Hong Kong are the first of the genus recorded from 
the Asiatic continent. 
The outstanding characteristic assigned to Spiloconis by 
Enderlein is the unusual length of the first two antennal 
segments, both of which are several times as long as wide ; 
in other genera of the family these segments are about 
as broad as long. Knowing only sexguttata and maculata 
at the time of the description of Spiloconis, Enderlein was 
led to believe that the genus might also be characterized 
by maculations on the fore wings, but picticornis, inter- 
rnpta and apparently cerata have unmarked wings. In all 
probability the most significant generic features will be 
found in the terminal abdominal segments of both sexes. 
An account of these terminal structures in picticornis is 
given in detail below, but until equivalent structures are 
known in other species, we cannot propose their generic 
application. 
The redescription of picticornis included below is based 
in part on the type, which is in the Museum of Comparative 
Zoology, but largely on eighty-five additional specimens, 
as follows: 35, 3 2, Taipo, Hong Kong, China, Jan. 1, 
1954, ex citrus (Flanders) ; 2 5 , 1 2 , Fanling, Hong Kong, 
Nov. 16 and 25, 1953 (Flanders); 23 <5 , 19 2, bred from 
Hong Kong stock at Riverside, California, Dec. 20, 1954 ; 
20 5, 10 2, same, May 7, 1954; 45, 3 2, same, April 17, 
1955. All of this material is preserved in alcohol and is 
deposited in the Museum of Comparative Zoology. 
The fore wing of the type is 2.3 mm. long and 1 m. wide 
(maximum) ; in other specimens which I have examined it 
ranges from 2.5 to 1.9 mm. long, and from 1.1 to .8 mm. 
wide. The general body color of living or alcoholic speci- 
ments is pale yellow; that of dried specimens is much 
darker. The frons is light yellow, occipital and genal areas 
brown. The antennae in all specimens which I have seen, 
2 Spiloconis ruja Nakahara, originally described from Japan in 1913, is 
now considered by its author to be a synonym of sexguttata (in litt.).
