within the angle. Beyond this line the wing is shaded with purplish and is thus 

 a little lighter than the basal portion. The s. t. line is |>a!e, irregular, broken, 

 preceded l>y a dusky shading. There is a dusky shade at the base of the fringes, 

 which is broken hy white dots at the end of the veins. The ordinary spots are 

 marked by dusky clouds on the costa. There are three white dots in the s. t. 

 space. Secondaries yellowish, smoky, veins and a lunule darker. Beneath yel- 

 lowish, powdery, with a purplish tinge. Secondaries with an outer dark line. 

 Both wings with a discal lunule. Expanse 1.20 in.: 30 mm.

Through the kindness of Mr. Strecker I owe a male of this spe- 

 cies, which I was at first inclined to consider a form of nitela. The 

 course of the t. p. line, however, is SO different and so constant in 

 the examples in Mr. Streeker's possession that I concluded him cor- 

 rect in separating the species under the new name. In a general 

 way the markings are like those of nitela ; but the t. p. line is much 

 less evident, besides differing in course. The species is also smaller 

 than nitela, though small specimens of the latter occur. More 

 materia] is needed to define the species satisfactorily. In sexual 

 characters it does not ditter to any appreciable extent from nitela.

Ground color fawn gray or brown, powdered with tine whitish or bluish atoms. 

 Bead and the interior portion of the collar a richer dark brown, without the 

 powdering, otherwise there is no marking on either head or thorax. Primaries 

 almost uniform in color, the median space slightly darker ; the t. p. line traceable 

 in most specimens, but never prominent m any : when best marked it is seen to 

 be geminate, made up of two very narrow lines, between which is a powdering 

 of whitish scales. In some cases even this is entirely wanting and the wing is 

 apparently uniform in color. Secondaries smoky, the veins a little darker and a 

 tendency to a discal lunule. Beneath mouse may. powdered with white scabs. 

 The fringes darker and uniform, except that they are tipped with white. Ex-

This insect is one of the most easily recognizable of all the spe- 

 cies, because of its almost uniform coloration. At first glance it 

 resembles nitela, and indeed looks like that species with all the 

 markings taken out, except the merest traces of the t. p. line and 

 the somewhat paler shading in the s. t. space. None of the exam- 

 ples that I have seen, and by the kindness of Mr. H. Bird I have a 

 verv prettj series before me, has any trace of an s. t. line. The
