This is the siiiallost of tho species in average expanse, and is still 

 shorter and rounder winged than J-J. (Icniiculalis. It is (juite easily recog 

 ni/.able by its almost iiimiaculate wings and is by no means unconiinoii 

 locally. It seems more fi-ecinent in northern localities, but I have 

 received it from Virginia, and westward it occurs in Iowa and Xebiaska, 

 I ha\e not had ir from Colorado or any point in tlie Sonoran faniial 

 region. 



The antenini^ are well developed in both sexes. In the male the Joints 

 are well marked and short, the lateral bristles are long and stout and 

 are set in deep i)its. Near to the insertion of these lateral bristles is 

 a rather large ])rocess set with hair about the tip, and near the tip 

 is another similai' ])rocess also clothed in the same May, while other 

 smaller tubercles and pits give rise to single hairs. This gives the 

 joints a much greater number of bristles and therefore a more brushy 

 01 brush like a[)pearance under a hand lens than any of the other 

 species thus far described. Tlie antenna' of the female are furnished 

 only M'ith weak lateral bristles, much shorter than those of the nude, 

 and the joints are without hairy ])rocesses. The male sexual char- 

 acters are of the same type as in U. liihricalis, but differ in that 

 the siii>erior margin of the harpe is not drawn out and chitinized, 

 while the process from the inferior margin is much longer and more 

 prominent. 



The Pseudaglossa forhcssi i , French, is based upon specimens in which 

 the maculation is quite well detined, and all of it traceable, resembling 

 thus, somewhat, a small JJ. iiihrirali.Sj except in wing form. To the 

 kindness of Prof. S. A. Forbes I owe an opportunity to examine one of 

 the types, which enables me to make the reference detinitely. A com- 

 p.irison of the tigures given on Plate i will at once show the relation- 

 ship of the forms.

Ground color smoky black without lust<n"; secondaiies scarcely 

 paler; abdomen narrowly white banded at the edges of the segments. 

 Primaries with all the lines present, narrow, white, and broken, accom- 

 panied, however, by black lines which are traci'able on close examina- 

 tion. Basal line reduced to a, slender white line. Transverse anterior 

 line distinct, though usually broken and sometimes reduced to a series 

 of white scales: ui>iight as a whole, but somewhat irregularly out- 

 curved in the interspaces. Transverse i)osteri(n" line distinctly marked 

 on the costa by a triangular white patch, but beyond that reduced to 

 a broken track of white scales in most instances; but it is sometimes 

 distinct though narrow; in course it is as in the preceding species
