SUBFAMILY ALEUKODICIN^. 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 (ouches the cubitus, and further- 

 more a smaller spot close beside the cubitus in the middle of the pos- 

 terior margin; finally, an almost circulgir 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 i\.merica. One male. 



11. Subfamily AleurodicinjI': n. subfam. 



The members of this subfamily are characterized by the presence 

 in the forewing of the radial sector and media. Radius ^ 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 : 



Geneba of the Aleueodicin.e. 



A. Pupa case without large compound pores. Forewing with radiusi and 



media well developed; vertex produced; lingula included; autennte of 

 seven segments DialeuroiJicux. 



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 Alrurodicus. 



D. Pupa case with conii)ound pores; radius i absent; media considerably re- 



duced; antenna; of four segments Paralcyrodes.
