SUBFAMILY ALEURODICIN/K. 25 
hind wing. Club in the forewing large, extending as far as the 
middle of the posterior margin. Forewings relatively broad, the hind 
wings rather narrow, particularly in the proximal part. Cubitus in 
the hind wing curved. 
Color of the wings and markings on the upper and lower sides uni- 
form. BasaL color of the forewing ochraceous yellow, with a rather 
finely increscent brown sprinkling, which is wanting only in the 
following locations: A pretty large semicircular spot, its base resting 
on the exterior margin at the mouth of an; another spot at the 
anterior margin close before the point; a still larger spot near the 
embouchure of an, which almost touches the cubitus, and further- 
more a smaller spot close beside the cubitus in the middle of the pos- 
terior margin; finally, an almost circular spot in the middle between 
the cubitus and the point of bifurcation of the radial vein. Between 
the two light-colored spots on the posterior margin of the wings there 
is a spot of rather dark-brown color. Hind wings sprinkled densely 
with dark-brown spots. Their apices somewhat lighter in color. 
There is a large ochraceous spot along the anterior margin at the end 
of the first third and another at the end of the second third of its 
length. Wings quite colorless, without any luster, without pubes- 
cence, and without any powdering. 
Length of forewings 5.5 mm. ; length of hind wings 3.75 mm. ; 
length of body 7 mm. ; length of abdomen 4.75 mm. ; width of thorax 
1.5 mm.; length of the ninth segment 1.75 mm.; length of forceps 
1.25 mm. 
Habitat. — In all probability South America. One male. 
II. Subfamily ALEURODiciNiK n. subfam. 
The members of this subfamily are characterized by the presence 
m the forewing of the radial sector and media. Eadius 1 may or 
may not be present, and the cubitus is rarely faintly indicated. 
The type genus is Aleurodicus. 
Four genera are at present included in the subfamily, which may 
be separated as follows : 
Genera of the Aleurodicin^. 
A. Pupa case without large compound pores. Forewing with radiusi and 
media well developed; vertex produced; lingula included; antennae of 
seven segments Dialeurodicus. 
B. Pupa case with no compound pores, but with agglomerate pores; radius i 
and media well developed ; antennie of seven segments Leonardius. 
C. Pupa case with large compound pores; radius i and media well developed; 
antennae of seven segments Aleurodicus. 
D. Pupa case with compound pores; radius a absent; media considerably rer 
duced; antennae of four segments Paraleyrodes.
