segments excepting the narrow, ill-defined apices, which are black. 

 Mid tibiae with two bristles on the outer front side near the middle; 

 hmd tibiae outwardly ciliate. Third vein with two bristles at base. 



Length 5.5 to 8 mm. 



Redoecribed from the type series of one male and six females (not 

 two males and five females as given by Coquillett) ; the type and one 

 other female ai-e from Virginia, and were reared by Koebele from 

 Acronycta hamamelis Guenee, emerging August 8, 1882; one male and 

 three females are from Maryland, reared from an Acronycta on oak, 

 July 28 and 31, 1882; one female without locality was reared from 

 Acronycta loheliae Guenee, April 21, 1885. The specimen reared 

 fi-om Orgyia, mentioned by Coquillett, is not now in the Museum or 

 has been placed elsewhere. One much larger female from Virginia 

 (Dyar) was reared from Acronycta; and one female without rearing 

 record is from Lafayette, Indiana ( Aldrich) . Reared from Alahart^a 

 argillacea Huebner at College Station, Texas, by Reinhard. 



The species is intermediate between Phorocera and ZenilUa in the 

 bristles of the faciala, hence has been referred to in both tables; it 

 is also intermediate between those species with discals and those 

 without, making it difficult to place satisfactorily in the table of 

 species. The Indiana specimen has a pair of distinct discals on the 

 third segment.

Front in male 0.25 to 0.27 of the head width (in three), para- 

 frontals from the vertex with uniform yellowish pollen, parafacials 

 paler yellow; frontal bristles about 10, only the upper one reclinate. 

 and it is much stouter than several next in front of it; lowest 

 frontals reaching level of base of third joint, facial ridges with 

 feeble bristles ascending to middle of third antennal joint ; antennae 

 black, third joint two and a half times the second, not quite reach- 

 ing the vibrissae. Palpi yellow, arista thickened on basal two-fifths. 

 Thorax gray pollinose with the usual changeable stripes indistinct. 

 Dorsocentrals 4, sternopleurals 3; scutellum with three lateral (the 

 middle one small) and a small pair of apicals. Abdomen with 

 rather thin gray pollen extending to the hind margins of the seg- 

 ments, showing a changeable median dark stripe; second and third 

 segments with large erect scattered hairs which almost approach the 

 size of discal bristles; fourth segment with the same kind of hairs 

 and some undoubted discal bristles ; genitalia small, the inner forceps 

 separate, thick, minutely hooked at apex on front side, outer for- 

 ceps shorter, less thick, with several minute retrorse booklets on 

 front near apex. Legs black, mid tibiae with two or three bristles
