to obtain further proof. Comparison with its European ally 

 woiild not be possible to many, so that I give to our species 

 a name and ivll description, placing it for the present in the 

 same genus. 



Petrophora salvata n. sp. 



Expanse 29-30 mm. Palpi projecting well beyond front, 

 slender, dark gray brown, tipped with paler. Antennae dark 

 gray, bipectinate in the &, slender and threadlike, shortly 

 ciliate beneath in the 9 . Front rounded, of gray brown and 

 white scales intermixed; a small interpalpal tuft. Thorax dark 

 brown mixed with white scales dorsally, on the patagiae 

 at sides, and heavily over the scutellar region. Abdomen 

 dusky white with a slight mixture of brown scales. The 

 second, third, fourth and fifth segments anally margined with 

 black. Primaries rather produced and pointed at apex with costa 

 strongly arched. Basal line crosses very close to base, rounding 

 out strongly at costa, then receding somewhat to inner margin, 

 the enclosed space dark gray. The intra and extra discal lines 

 are both double, forming bands, the former in width about half 

 the latter. It leaves costa one-third out, rounding out slightly 

 on crossing, thence straight to inner margin. The broad space 

 between it and basal line, and at centre of wing, is nearly clear 

 of dark scales, and assumes a bluish gray cast. A trace of wavy 

 gray lines sometim.es appears in former, and the small round 

 black discal dot is conspicuous in the latter. The outer line of 

 extra discal band leaves costa about two-thirds out, with an in- 

 ward curve to vein m', and another to vein m', thus forming 

 a small angle at both, thence in a series of outward waves between 

 veins, reaches inner m.argin near to anal angle, its general course 

 being nearly straight across wing. The inner line leaves costa 

 at centre, m.akes a sharp outward angle just below costa, then 

 parallels the outer line in a similar series of waves, to inner margin 

 at centre. These bands are filled with black and dark brown 

 scales to a point just below cell in the former, and to vein m' in 

 the latter whence to inner margin they are of the pale ground 

 color, except an occasional darkening just at inner margin. A 

 pale band parallels the outer line of extra discal across wing, 

 sometimes nearly white, and the dusky submarginal space out-
