THE CANADIAN ENTOMOLOGIST. 155 



shade which follows the t. p. line. S. t. line whitish gray, broad, distinct, 

 with a subcostal dentation else continuous and even. Terminal space 

 blackish ; broken black points indicate the terminal line. Fringes reddish 

 brown. All the veins marked by blackish scales, and there is a blackish 

 shading over the median space anteriorly, below median vein and on the 

 inferior portion of the basal field. The male has the lines and spots less 

 obvious and the shading of the wing more strongly contrasts. Hind 

 wings with reddish brown fringes, shaded with fuscous and with a blackish 

 exterior shade and faint median line. Beneath the wings are irrorate with 

 rufous • on both pair the terminal spaces are contrasted by a whitish 

 coloring. A common subterminal shade and exterior line ; discal marks 

 linear, luniform. Beneath the vestiture is reddish brown, as are the sides 

 of the palpi ; above, with the front, these latter are pale. Expa?ise 35 

 m. m. 



In the male the conformation of the subterminal pale shading is 

 indistinct ; the blackish shading basally on interior margin is restricted, 

 the claviform is shorter, not attaining the median shade ; the dark olive 

 brown tint of the s. t. space forms a spot along the s. t. line opposite the 

 cell. In this species the form of the thorax, which is darker colored 

 posteriorly, recalls that in Lithophane. 



Lederer only gives armature to the middle and hind tibiae in his 

 diagnosis of Pachnobia. P. carnea, the type, has all the tibiae spinose ; 

 so has Pachn. scropulana ( Agrotis scropulana Morr.) The species have 

 the habitus of Graphiphora ( Taeniocampa). I find that none of the 

 characters given by Mr. Morrison in a recent number of Psyche, to 

 distinguish his Agrotis scropulana, are valid, except that of the basal 

 markings of the primaries, to which I am the first to draw attention. I 

 am therefore still of the opinion that it is not certain that the White 

 Mountain species is really different. I have recently re-examined my type 

 of Matuta Catharina. I believe it to be a female ; the simple antennae 

 may not distinguish it from Pachnobia in this event, but it is different by 

 the unarmed fore tibiae. It has a resemblance to Pachn. orilliana in 

 habit and the black stains on the veins. Our North American species of 

 Pachnobia will be as follows : 



Cor nut a Grote, 

 Scropulana (Morr.) 

 (An spec. seq. ? ) 

 Carnca (Thunb.) 

 Orilliana Grote.
