with the maculation almost entirely lost. By careful study it is possible to trace an 

 almost upright, geminate t. a. line, a vague, diffuse median shade, a slightly irregular 

 s. t. line and a large reniform which is somewhat constricted medially. Secondaries 

 paler, more smoky gray, lightest at the base. Beneath, uniform, slightly more red- 

 dish gray, somewhat powdery, with an obscure dusky line on both wings. 



Expands. — r.12-1.15 inches = 28-29 mm - 



Habitat. — Claremont, Calif. , Mr. Carl Baker. 



Two male examples in very fair condition, neither of them with 

 date of capture. The species belongs in the rubifera series, but is 

 distinguished from all of those known to me by its uniform mouse gray 

 color on which the normal maculation is barely traceable. 

 Euxoa claromonta, new species. 



Head and thorax ashen gray, head a little paler ; collar with a transverse, 

 median black line ; thoracic tuftings well marked. Abdomen a somewhat paler gray, 

 lighter in the males than in the females. Primaries pale ashen gray, powdered with 

 smoky ; maculation not well defined, reniform and terminal space usually the darkest 

 part of the wing. Basal line geminate, usually marked on costa and sometimes, also 

 by black scales below the median vein. T. a. line geminate, marked on the costa in 

 all specimens and below that either lost altogether or traceable across the wing; in 

 the latter case nearly upright, a little outcurved in the interspaces. T. p. line gemi- 

 nate, inner part best markedrand somewhat lunulate, only a little bent over cell and 

 then about parallel with outer margin. S. t. line a little irregular, of the paler 

 ground, defined by the dark' terminal space and, sometimes, by a dusky preceding 

 shade as well. A series of black terminal lunules, followed by a yellowish line at 

 the base of the gray fringes. Claviform outlined in one example, barely indicated in 

 others. Orbicular oval, oblique, tending to become irregular and incompletely closed 

 above, more or less defined by black scales, followed by an annulus of the pale ground. 

 Reniform moderate in size, kidney-shaped, ringed with pale and filled with blackish. 

 Secondaries white with a variably marked dusky outer border, not differing much in 

 the sexes; a narrow discal lunule. Beneath, gray, powdery, secondaries paler; a 

 more or less defined outer line and discal spot. 



Expands. — 1.2 5- 1.40 inches = 31-35 mm. 



Habitat. — Claremont, Calif., Mr. Carl Baker. 



Three males and three females, no two alike. This is one of those 

 obscure, variable species of the pitychrous series which is always 

 troublesome when only single specimens are at hand. Its allies are 

 Candida and detesta though not readily confused with either when ma- 

 terial is at hand for comparison. None of the specimens are dated. 

 Mamestra pectinicornis, new species. 



Head and thorax dull, smoky brown. Abdomen gray brown. Tarsi ringed 

 with whitish and rather prominent. Primaries deep smoky brown over a lighter 

 base, giving a somewhat powdery appearance. The median lines are barely trace- 

 able as somewhat more brownish scales occasionally edged by black scales. S. t.
