one-third its leng:th ; fork 4 sometimes absent, its pedicel about twice its length, 

 the median cell thus extremely long. Expanse 14 mm. 



Many specimens from Washington, D. C, August. 



P<»lyceiitropnS carol ineiisis* Bks. — Head densely clothed with yel- 

 lowish gray hair in front, and blackish behind ; palpi pale; antenniB yellowish, 

 very strongly crenate within; prothorax with yellowish hair; rest of thorax 

 and the abdomen brown, former with some yellowish hair; legs pale yellowish, 

 tarsi rather darker. Wings uniformly clothed with jet black hair, and with 

 about twt.ity sri'all snow-white spots, several arranged in an irregular, broken 

 band across wing near middle, two at the pterostigma, one or two at posterior 

 apical angle, one at arculus, and two or three on the apical margin, those in basal 

 part of wing indistinct; a tuft of erect black hair at base of forewings; posterior 

 wings blackish, with darker venation ; discal cell slender, as long as its pedicel ;. 

 fo-k 1 not as long as its pedicel, fork 3 longer than its pedicel, fork 4 reaching 

 basad of fork 3, but with a long pedicel ; fork 5 reaching much farther toward 

 base. Expanse 13 mm. 



One specimen from Black Mt., North Carolina (Beutenmiiller). 



Polyceiitropus dispar n. sp.— Head black, with black bristles and 

 white hair; palpi brown; antennse pale, the joints tipped with black; thorax 

 dark, with some black bristles and pale or whitish hairs, mostly on the middle; 

 abdomen yellow-brown ; legs yellow, the tibiae dark, and the tarsal joints dark, 

 except the extreme base of each joint is snow-white. Wings dark, irregularly 

 clothed with dark hairs, in places jet black, forming patches and streaks; the 

 apical part of wings mostly dark, ending in an irregular band, beyond paler; 

 the middle area mostly occupied by a pale triangle; a large pale spot behind 

 anastomosis, containing a black spot ; fi-inge. mostly brown, some white patches; 

 hindwings dusky, darker at tips. It agrees quite closely in venation with Poly- 

 centropus (as restricted by McLachlan) ; no closed cell in hindwings, and all the 

 forks are present in the forewings, an oblique cross-vein in costal area; but I 

 cannot see any subapical spur on leg 1, in fact I think there is but one at the tip, 

 which is small and appressed to the leg. Expanse 11 mm. 



Specimens from Tucson, Arizona, June 5th (Oslar). 



Polyceiitropus arizonensis n. sp. — Face brown, vertex black, with

 especially along the costa, near pterostigma and on- apical margin, and a larger 

 one above the arculus. Hindwings blackish, darkest on costal margin toward 

 tip. Antenine slightly crenulate on inner side; spurs 3-4-4. Upper branch of 

 radial sector forked fully one-half way out from anastomosis; lower branch of 

 median forked beyond upper branch. Expanse 22 mm.
