NOCTURNAL LEPIDOPTERA FOUND IN CANADA. 257 



black and brown as far as the extra basal line, which is thick, brown, 

 and irregular, and is followed by a white fascia, enclosing a rather 

 large black discal dot ; median space streaked and clouded with 

 brown ; reniform spot blackish-brown ; elbowed and subterminal lines 

 fine, doubledj parallel, and well-defined posteriorly, but losing them- 

 selves anteriorly in a dark costal patch ; the elbowed thickened into 

 a black spot opposite the reniform ; immediately succeeding the sub- 

 terminal, a pure white slightly wavy fascia running across both wings, 

 and followed by a brownish-black parallel band ; a series of black 

 marginal dots on a paler space. 



Posterior wings whitish, with a small discal dot, a few indistinct 

 transverse lines, and a well-defined brown black-edged line correspond- 

 ing to the sub-terminal on the anterior wings ; the marginal dots 

 rendered obscure by a number of black and brown streaks. Under 

 side whitish-cinereous, with discal lunules, a dark transverse line, a 

 marginal series of black dots, and a second discal spot on the anterior 

 wings. Length of body, .6 inch ; alar expansion, 1.75 inch. 



Hab. — Cobourg ; May and June, at sugar. 



This species bears a considerable resemblance to H. minerea, but 

 may be distinguished by its much paler colour, and the sub-marginal 

 white fascia and black band, instead of the two large terminal glaucous- 

 white lunules. 

 9. H. DUPLicATA, nov. sp. 



Blackish-cinereous, male darker ; female clouded with tawny or 

 ferruginous. Thorax with a fine black band in front ; tegulse tipped 

 with ferruginous. Anterior wings with all the lines distinct, black ; 

 extra-basal with a sharp denticulation just below the costa, then 

 slightly sinuous ; elbowed, with two nearly rectangular denticulations 

 anteriorly, irregularly curved posteriorly ; subterminal forming two 

 regular arcs which unite in the middle in a sharp denticulation. Across 

 the middle of the median space, which is slightly paler than the rest 

 of the wing, there is an irregular dark band edged with black, and 

 enclosing the deep black reniform spot (in some specimens this band 

 is almost obsolete, and in the male quite so). Marginal space paler, 

 covered with numerous black dots and streaks, but not divided by the 

 usual shade in thr middle. 



Posterior wings cinereous, with a dark brown black-edged submar- 

 ginal band commencing at the anal angle, where it is elbowed, thence 

 straight across the wing, but becoming obsolete before it reaches the 

 costa ; faint traces of another above. Under side of both wings cine-
