THE CAXADIAX ENTOMOLOGIST. 



Fore wings moderately broad, with hind margins well rounded out. 

 (In IViimata these margins are very straight and the wings pointed.) 



Thorax with a whitish transverse line posteriorly and two minute 

 black dots, one on each side the middle. Abdomen with black band on 

 second segment. 



Fore wing : Basal line evenly curved. Intradiscal very sharply 

 angled at cell. Extradiscal curving inwardly from costa, then outwardly 

 at cell, and thence in a series of scallops to inner margin ; some black 

 dashes running from this line inwardly on the veins. Crossing the median 

 space are three fine lines, heaviest on the costa. The two outermost are 

 subparallel to the extradiscal, but the innermost is not parallel to either 

 intra- or extradiscal. This line includes a small black discal spot. There 

 is a narrow pale band beyond the extradiscal line, bounded outwardly by 

 an indistinct fine line, exactly parallel to the extradiscal ; this space is 

 divided by a similar fine line hardly visible, except on the veins. 



The submarginal space is a little darker than the rest of the wing, 

 and is divided by a distinct scalloped pale line. Marginal line fine, 

 broken, but very black and distinct. Fringe moderate, faintly spotted. 



Hind wing with the markings of the fore wing faintly continued, the 

 intradiscal of fore wing becoming the basal line on hind wings. The pale 

 extradiscal divided band of fore wing can be traced right across hind wing. 

 Discal dot minute. 



Beneath, fore wing lightly scaled, smoky ; two median lines and the 

 extradiscal marked on costa, and fainily visible across wing. Extradiscal 

 pale band also traceable across all wings. 



Hind wing a little paler ; five cross lines quite distinct, two intra- and 

 three extradiscal. Discal dots distinct. 



The markings of the hind wings, both above and below, are very 

 different from Quebecata. 



Type, a female from Mr. C. H. Young. It is dated Ottawa, 9, VI, 3, 

 and is in perfect condition. 



I name this after Mr. Arthur Gibson, who has helped me very much 

 with species of Ottawa Geometridse. 



Eupithecia fasciata, n. sp. 



There can be no question but that this species is very closely allied 

 to the E. bi/asciata of Dyar, described from Kaslo. In fact, Dr. Dyar,
