The insect described below as the type of this genus I have been 
unable to place in any genus known to me. I do not deem it necessary 
to give any further diagnosis of the genus than to say that it is an 
Ypsolophus, except as to the antennæ and palpi. ‘The former are 
minutely pectinated, and are otherwise like those of Ypsolophus. The 
terminal joint of the palpi is, perhaps, a little more robust than in 
Ypsolophus ; the second joint is clavate, rounded at the apex, laterally 
compressed, vertically thickest just before the end, forming a thick, rather 
compact, undivided brush. As to the length of the palpi and the relative 
lengths of the joints, it agrees with Vpsolophus. 
B. costolutella. WN. sp. 
- Yongue and face brownish-ochreous; palpi ochreous yellow; head 
brown on top, ochreous yellow above the eyes; thorax dark shining 
brown, except the anterior margin and patagiæ, which are ochreous 
yellow. A line drawn from the base of the anterior wings, near the 
dorsal margin, to the beginning of the costal ciliæ, will divide the wing 
into a narrower anterior (or costal) ochreous yellow portion, and a wider 
posterior (or dorsal) portion, which is shining dark brown. The anterior 
or ochreous yellow portion, however, becomes furcate about the apical 
third of the wing, sending a curved branch into the dark brown portion ; 
this branch is at first wide, but curved, gradually narrowing towards the 
dorsal cilize, which it does not quite reach. There is a faint, narrow, 
ochreous yellow hinder marginal line at the base of the ciliæ, which are 
paler than the dark portion of the wing, their basal half being darker than 
the apical half. Posterior wings and their ciliz grayish slate color. Alar

If one could believe that the projecting brushes had been removed so 
evenly and smoothly as in this insect, without otherwise injuring them, 
and leaving no trace that they had ever been other than they now are, 
then this insect would be an Yfsolophus, resembling Y. epatoriella (vid. 
post-prox ).
