AMERICAN LEPIJ)OPTERA. 85 



yellowish tinged with fuscous, anterior and middle tibiae aud tarsi more conspic- 

 uously dark brown, joints of latter pale at apex. 

 Exp. 10.0-12.0 mm. 



Hab. — Pennsylvania (Hazleton); California (Placer County). 



A peculiar species, differing in appearance from our other species. 

 The costa of forewing more arched from base; the costal cilia give 

 the appearance as though the costal margin was emarginate beyond 

 the middle. This species has veins 7 and 8 of forewing stalked, but 

 does not differ otherwise in neuration ; its distribution is certainly 

 remarkable; my specimens were taken at light. Scale tufts of 

 forewing very feeble. 



II. miscecristatella Ch.— Dyar's List, p. 574, No. 6544, 6542, 6543.— 

 Palpi and face creamy white, labial palpi externally, except apical half of ter- 

 minal joint, fuscous; vertex white and fuscous intermixed, varying from nearly 

 white to dark fuscous; antennae fuscous, paler beneath. Thorax fuscous brown, 

 speckled with gray. Forewings sordid white, dusted more or less thickly with 

 fuscous scales and intermixed with golden yellow scales, aggregated into lines 

 and patches; markings dark fuscous brown, and arranged as follows: Extreme 

 base of costa, and to a less extent the base; an oblique costal spot very near the 

 base, and containing a patch of yellow scales within the costal margin ; an oblique 

 fascia, more or less complete before the middle, containing likewise a similar 

 patch of yellow scales, a transverse fascia, more or less complete at two-thirds, a 

 well marked costal and dorsal spot between the second and third fascia, beyond 

 the last fascia are four oblique white costal spots, and about three on the dorsal 

 margin; a small scale tuft just before the first oblique costal spot below the fold, 

 two tufts along the inner margin of the second oblique fascia, the larger one 

 transverse on the disc the smaller further outwards below the fold, a very small 

 tuft below outer end of fold ; a large transverse tuft at end of cell, these tufts 

 consist of dark brown scales, faced externally with golden yellow. The fuscous 

 dusting conceals the ground color more or less completely in the apical partof 

 the wing; the golden yellow scales at times form a subcostal streak from near 

 the base. Cilia grayish with a well-defined dividing line at one-third, and an ill- 

 defined one at two-thirds, and with pale lines from the marginal spots. Hind- 

 wings grayish fuscous, with brassy lustre, cilia gray. Abdomen above grayish 

 fuscous; body beneath and legs yellowish silvery white; anterior and middle 

 tibiae and tarsi dark fuscous brown, tarsal joints paler at apex. 



Exp. 9.0-11.0 mm.; 0.36-0.44 inch. 



Hab. — Atlantic States. 



I have seen the type in Cambridge of this species as well as of 

 Pithys aurocristatella and fuseocristatella, and fully agree with my 

 friend Mr. Busck, who, somewhat cynically, states that they arc 

 specimens of the same species in various states of rubbedness ; auri- 

 cristatella has the head entirely whitish and the wings more con- 

 spicuously white than usual ; fuseocristatella is badly worn and
