crossing the Atlantic three times. Upon examining all my males- in 

 this group, I found but two with traces of the pencil present, the 

 rest showing only the scar where it had been attached. My male type 

 of perplexata n. sp. hereinafter described, has the hair pencil on both 

 legs seemingly intact, in length about half that of the tibia, the hair 

 very fine and curled at the tips. In notata it is straight and coarser. 



PHILOBIA Dup. 

 1829. Histoire Nat., VII, 195. Type, notata Linn. 



In this genus the antennae are serrate, each joint, toothed near the 

 outer end, is tipped with a fascicle of hairs in the d", almost simple 

 and evenly ciliate with a fine hair-like bristle in the ?. Front 

 rounded, smooth, palpi slightly extended beyond it ; tongue well- 

 developed; hind tibiae with two pair of spurs in both sexes, the male 

 with a small external pencil of hairs, generally removed by abrasion. 

 Thorax and abdomen without tufts. Wings rather broad, the costa 

 of primaries much rounded at apex, and below it the outer margin 

 excavated between veins R^ and M^, and in the 3 a fovea below, at 

 base beneath cell. Secondaries with sharp angular point at margin, 

 opposite vein M^. 



Philobia ulsterata new species. 



Expanse, ^ 24-28 mm., 5 25-30 mm. Front, palpi, antennae and collar 

 brownish ochre, the latter decidedly darker. Body and all wings above are 

 white, but peppered thinly, and minutely strigate with dusky scales ; they have 

 a soiled appearance. Dusky lines cross primaries, their inception at costa 

 marked with heavy dark chocolate brown spots. The basal spot linear, cross- 

 ing costa toward outer margin and continued by a narrow dusky line, curving 

 outward to inner margin. The second spot is quadrate, and the line from it 

 is usually broader and darker and runs straight across wing, often waved 

 in its course. The extra discal is linear, and like the basal in its direction 

 across costa to vein M', then in a fine line of same color, wavy and heavily 

 marked at center of wing, fading into dusky below, runs direct to inner mar- 

 gins. Apical spot broad, quadrate, extending to vein M', leaving between it 

 and the extra discal spot a triangular white space at costa. Broken below vein 

 M', the line reappears, at wing center, as three heavy dark spots, separated 

 by the white veinings, the central one much the largest. All cross lines 

 marked with two or three dark brown scales at vein crossings. A heavy dark 

 brown marginal within excavation below apex, and dots between the veins
