I have an enormous series of specimens of this insect, both males 

 and females. It is absolutely impossible to distinguish between 

 the females of R. r^alafia and B. sosia. Sosia merely differs from 

 (/alalia in being without the raised velvety brand of scales upon 

 the primaries below the end of the cell. Some vestiges of this 

 sexual mai'k, however, appear in a few specimens. I am perfectly 

 convinced that the insects do not specifically differ from each 

 other, and that we are simply dealing here with dimorphism 

 affecting the sexual stigmata of the male sex. This is a singular 

 fact, and, so far as my observation extends, hitherto unobserved. 



Pabosmodes, gen. nov. 



Closely allied to the genus Osmodes, from which it differs princi- 

 pally in the form of the palpi, the third joint of which is long and 

 porrect, whereas in t3'pical Osmodes the third joint is short and 

 suberect. 



The antennae are moderately long, exceeding the middle of the 

 costa. The neuration of the primaries and the secondaries is as in 

 Osmodes, and there is likewise at the origin of veins 2 and 3 of the 

 secondaries a raised patch of scales as in Osmodes. The primaries, 

 as in the latter genus, have also a long tuft of hairs about the 

 middle of the hind margin ; these hairs are ordinarily folded 

 forward against the under surface of the primaries as in Osmodes.
