stalk, the nervule running parallel with the medio-superior nervule. In repose 

 the wings are deflexed in the apical portion along the middle. 



Head smooth, vertex elongated. Face smooth nearly naked, concealed by 

 the labial palpi ; forehead with a thin tuft. Eyes rather small, moderately 

 prominent. Antennae setaceous, pubescent beneath. Palpi exceeding the face 

 by more than one-half the length, crambiform, porrected, flattened, and taper- 

 iDg from the middle to the end ; terminal joint distinct, short, smooth and 

 ovate ; middle joint suddenly arching upward at the face, whence it is porrected 

 and slightly deflexed, roughly clothed with scales above and beneath. Tongue 

 rudimentary, almost obsolete. 



P. s e n t a n a Head and palpi dark brownish, slightly sprinkled with 

 grayish. Fore wings dark grayish brown, with an oblique line of dark brownish 

 scales near the base, terminating in a tuft of the same hue on the fold. An 

 oblique line of elevated dark brownish scales crosses the wing from the costa 

 within the middle, to the middle of the inner margin, and in the middle of the 

 wing, exterior to it, is a short blackish streak, beneath which the wing is dis- 

 colored with dark reddish brown ; along the costa, exterior and parallel to the 

 central line, are two shorter and similar Hues. Near the hind margin, and 

 parallel with it, are two lines of elevated dark brownish scales crossing the 

 nervules. Hind wings yellowish fuscous. 



The larva feeds on the leaves of Viburnum pr u n i folium. It is dark brown, 

 with paler brown papilliform points, and two indistinct subdorsal lines of the 

 same hue. It leaves its food plant to weave a white silken cocoon, and appears 

 as an imago early in July. 



P. flavedana. Reddish saffron. Fore wing3 with an oblique line near 

 the base, terminating in a tuft on the fold ; an oblique central fascia edged on 

 each side with elevated scales, and a fascia near the tip, joining the central 

 fascia, reddish brown. Near the terminal border of the wing is a line of raised 

 scales of the general hue. Hind wings reddish saffron. 



Male? Palpi reddish brown, terminal joint yellowish. Head and thorax 

 ochreous yellow. Fore wings yellow, deeper at the base than at the tip, with 

 the middle of the wing discolored with blackish brown, having a purplish hue. 

 At the base of the fold, on its middle and about the end of the disk, are tufts 

 of scales, and with two transnervular lines of scales in the yellow portion. The 

 extreme hind margin is reddish ochreous, varied somewhat with dark brownish. 



These specimens may be only variations of P. s e n t a n a. 



Anchylopera Stephens. 



Fore wings rather narrow, with the tip usually produced acutely, and the hind 

 margin falcate or concave. The disk is slightly above the middle of the wing, 

 widening from base to apex, with four subcosto-marginal nervules ; apical 

 simple; two distinct diseo-central branches. The medio-posterior arises be- 

 tween the first and second marginal nervules. In the hind wings the discal 

 vein is curved. The median vein is either two-branched, with a medio-discal 

 nervule, or three-branched loith the two superior branches on a moderately long com- 

 mon stalk, and a medio-discal nervule on a short peduncle. 



Head rather rough. With ocelli. Face slightly tufted in the middle. Eyes 

 moderate. Antennas setaceous, pubescent beneath. Palpi exceeding the face 

 a little, slightly ascending but porrected, thickly and truncately scaled towards 

 the end; terminal joint slender, minute, usually drooping, and almost concealed 

 in the terminal scales of the middle joint, which is somewhat curved and 

 roughly scaled beneath and at the end above. Tongue about one-half as long 

 as the anterior coxae, and a little longer than the labial palpi. 



Tip of fore wings produced. Median vein of hind wings 2-branched, with 



medio-discal branch.
