DlRPHIA MARGINELLA. 



Mas. Nigro-fusca ; antenna pallide lutea, late pectinata ; abdo- 

 men nigrum, segmentis luteo fasciatis ; tarsi lutei ; ala fer- 

 rugineo-fusca, fimbria alba strigata ; antic a fascia nigro-fusca 

 obliqua indistincta, striga alba clavata, linea exteriore cinerea 

 dentata nigro-fusco marginata ; postica basi cinerea, fascia 

 exteriore dentata fusca cinereo submarginata. 



Male. Blackish brown. Palpi very short. Antennae pale 

 luteous, broadly pectinated. Abdomen black, with a broad luteous 

 band on the fore border of each segment ; apical tuft luteous. Legs 

 stout, pilose ; tarsi mostly luteous. Wings ferruginous-brown, with 

 white transverse streaks on the fringe. Fore wings hardly acute, 

 with an indistinct oblique blackish brown band which includes part 

 of an oblique clavate white streak ; the latter is yellowish beneath ; 

 an exterior oblique dentate cinereous line, which is bordered with 

 blackish brown on the inner side and is wholly blackish brown 

 beneath. Hind wings cinereous towards the base, this hue bordered 

 by an indistinct brown band ; an exterior brown dentate band which 

 is indistinctly bordered with cinereous on the outer side ; basal part 

 of the interior border with long luteous hairs ; under side with more 

 distinct markings. Length of the body 17 — 20 lines ; of the wings 

 48—52 lines. 



The dentate exterior line and the white spotted fringe of the 

 wings distinguish this species from D. varia.
