296 THE CANADIAN ENTOMOLOGIST 



received from the Provincial Museum, Victoria, B.C., through Mr. 

 E. H. Blackmore. It may be described as follows: 



Hydriomena macdunnoughi, sp. nov. 



This species has a very close resemblance to H. ruherata in 

 colour and style of markings, and can be best compared with that 

 species. 



Palpi moderate, front of head dark ashen, thorax and abdo- 

 men fuscous. Fore wings dark ashen gray with a ruddy tinge. 

 The basal band runs straight across the wing, except where it 

 bends outwardly on the median vein and again sharply outwards 

 at vein 1. The mesial band as a whole is smoky fuscous with a 

 ruddy tinge and crossed through the middle by the usual watery 

 band. The intradiscal, black band runs straight to median vein, 

 then makes an incurve to inner margin. Mesial space quite nar- 

 row, pale ashen with a ruddy tinge, and containing a prominent, 

 linear, discal dot. Extradiscal line running almost straight across 

 the wing, irregularly scalloped inwardly on the veins. Marginal 

 area ruddy grey with a smoky, curved band running through the 

 centre. There are geminate black dots at the base of the fringe. 

 Hind wings dark, smoky gray with a prominent black, curved 

 band beyond the discal spot. 



Fore wings beneath smoky with two outer curved bands be- 

 yond the discal spot. Hind wings of same colour with a prominent, 

 black, curved extradiscal line, beyond which is a second faint line. 



The fringe on all the wings is short and fuscous. 



The palpi in this species are much shorter than in ruherata, 

 and the general colour is a darker smoky fuscous with ruddy tinge. 

 The course of the basal and median bands is different from that 

 of niberata. The uncus is broader near the tip, and the valvae 

 do not narrow as in ruherata, but are broad and full one-third 

 back from the tip. 



Expanse 28 mm.
