 pilose, but thorax sometimes largely yellowish pilose, and pile on sides of 

 abdomen sometimes rusty-brownish. Apex of wings hyaline, the base 

 brownish, the outline of this color extending from apex of first vein 

 obliquely to base of fourth posterior cell, then following penultimate vein 

 to hind margin of wing ; axillary cell almost wholly hyaline ; apex of first 

 basal cell hyaline ; only the extreme base of discal cell brown. Eyes

Oncodocera valida Wied. (Syn. Anthrax valida Wied. ; Anisotamia 

 exiuiia Macq.) — As I have never seen a specimen of this species, I give 

 below a translation of Wiedemann's original description (Aus. Zwei. Ins., 

 II., page 636). 



" Deep black, abdomen having the apex each side fulvous pilose, in 

 the male with two vittse ; 7 lines. From Oaxaca in Mexico. 



" Antennae black, with a simple style. Eyes of the ^ contiguous, so 

 that on the crown only a small space remains, extended in a point 

 anteriorly. Besides these, the whole insect is black, and black pilose, 

 only the end of the abdomen with golden-yellow, beneath even foxy- 

 reddish, glossy, silken pile, which in the male forms two broad vittae that 

 extend to the first segment, but in the female only forming two spots which 

 extend across the last two segments. Wings on the costal margin for two- 

 thirds their length brownish ; in the male less dark. Veins as in the fifth 

 tribe, except that the inner branch of the forked vein is connected with 

 the next following vein at the hind margin of the wing."
