loped. Fringes checkered brown and white. Secondaries with only one prominent 

 brown line crossing the wing outward of the linear discal spot. This is curved gently 

 inward and outward before reaching the inner margin and is marked heavily on the 

 veins. Outward of this line are the same brown shade bands with white denticulate 

 line and terminal scalloped brown line arranged as described for the primaries. 

 Beneath, both wings are almost uniformly whitish-gray, somewhat brownish on the 

 costa and subapical portions of primaries. A large, oval, brown discal spot on fore 

 wings, but that on hind wings scarcely indicated. 



Types. — Eight males and one female in the author's collection. 

 Co-types will be placed in Rutgers College collection. 

 Habitat. — Stockton, Utah, July 2-14, 1907. 



15. Selidosema anastomosaria, new species. 



Expanse, 31.5-35 mm. Head white with a blackish cross band between the 

 bases of the antennae and another across the middle of the front. Thorax white with 

 a few black scales ; collar blackish. Abdomen banded black and whitish. Ciround 

 color of wings whitish shaded with pale, dirty ocherous and sprinkled over rather 

 sparsely with brown atoms. Primaries with three prominent, brownish-black trans- 

 verse lines, the intradiscal, median and extradiscal. Basal line indicated on costa 

 by a distinct mark of the same color. Intradiscal line begins one third out from base 

 on costa, extends broadly outward to edge of cell, bends inward at right angles and 

 is thence somewhat scalloped to inner margin, the last scallop projecting quite far 

 outward. Median line more diffuse, begins from a large, squarish patch at middle of 

 costa, extends through discal spot and then runs obliquely inward taking an irregular 

 course and almost meeting the projecting scallop of the preceding line. Extradiscal 

 line originates on costa as far out from median line as the intradiscal line is inward 

 of it and in general extends roundly outward, then sweeps inward anastomosing 

 with median line between the cubitus and anal veins, and then runs shortly outward 

 to inner margin ; between the veins it is inwardly scalloped, those in the central por- 

 tion being less strongly curved, and the angles extend in black points outward along 

 the veins. Externally of this line a broad band of the ocherish ground color runs 

 parallel with it. Subterminal line white, strongly dentate, subparallel to outer 

 margin ; internally of it a large patch of brown scales appears between veins M, to M . 

 and sometimes another equally as large at the costa. Terminal line blackish, evenly 

 scalloped around the veins. Fringe gray divided by a brown line. Secondaries 

 with two brownish-black lines in the central portion of wing which begin on inner 

 margin and extend strongly over two thirds of the wing but are lost before reaching 

 the costa. The first is inward of the discal spot and rather even in its course ; the 

 second is somewhat irregular, runs toward the discal spot to M,, then curves out. 

 wardly around it. Subterminal line white, broad and wavy ; between it and the 

 extradiscal line a band of the white ground color is plainly marked. Terminal line 

 sharply indicated, scalloped as on fore wings though not so evenly. Fringe as in 

 fore wings. Discal spot rather large, linear solid. Beneath, even grayish-white, 

 semetimes with a subapical brown cloud, speckled with faint brown atoms and 

 marked along the costa of primaries by brown flecks. Terminal line distinct ; discal 

 spots present on all wings.
