' P- d^liU'H.da Hulst, n. sp. 

 / P. gertrnda n. sp. — Expands 40-42 mm. Palpi light ocher, stained with 

 fuscoiis towards ends ; front ocher fuscous ; antennae of same color, lighter basally ; 

 thoi'ax ocher below, reddish brown above. Abdomen dull whitish : fore wings 

 bright reddish brown, almost fulvous, marked with broad, white, longitudinal 

 stripes on spaces between the veins ; the anterior one between 7 and 8 is subniar- 

 ginal and short; the next reaches from margin almost to stem of 8 and 7 ; the 

 next between 5 and 6 extends from margin, merging with the next lower, which 

 itself is faint towards margin, the merging being on vein 5 outside of cell and 

 extending longitudinally across cell, more faintly towards base, the lower part 

 separating within cell and joining a corresponding band just below subdiscal 

 vein ; sometimes the ground color is apparent on vein 5 all its length, and the 

 two white bands do not actually unite; the jiarts between 3 and 4 and 2 and 3 

 are short, not reaching cell: the bands between 1 and 2. and posterior to 1, are 

 straight, the former joining with the one between 4 and 5 near base but not 

 reaching it, the latter reaching to base; hind wings with lines broadened so that 

 the fulvous color is mostly lost on basal two-thirds, and is fainter outwardly on 

 veins; beneath as above, the fulvous more faint on fore wings, stronger on bind 

 wings, especially anteriorly.

Palpi long, porrect, heavy ; tongue developed ; front with hair 

 tuft; antennae pectinated in both sexes, in S almost to apex, pecti- 

 nations moderate ; thorax loosely scaled ; abdomen smooth ; legs 

 smooth, hind tibise not swollen, without hair pencil, with two pairs 

 of spurs in both sexes; fore wings subfalcate, sometimes obscurely 

 angulate at 4, especially in % , 12 veins, 6 and 7 stemmed, 10 and 



1 1 from cell, without fovea below in % ; hind wings 6 and 7 stemmed, 

 5 undeveloped, 8 separate from cell. 



Dr. Packard figures the fore wings with 1 1 veins only. In many 

 specimens I have found no such example and no such tendency.
