DESCRIPTIONS OF THREE NEW SPECIES OF EUPITHECIyE 

 FROM WESTERN AMERICA. 



BY GEO. W. TAYLOR, NANAlMO, B. C. 



Eupethecia Laggan ata, n. sp. — Expanse, 22 mm. 



Palpi short and sto ut. Head, thorax and fore wings dark gray, with 

 a brownish tinge. Abdomen and hind wings paler, the first segment and 

 the last two segments of the abdomen whitish. 



Fore wings very long and narrow, pointed at apex, tornos rounded. 

 The wings are crossed by numerous alternate pale and dark lines, the 

 dark lines being emphasized on the costa, and the paler ones on the hind 

 margin. There are about four of the pale lines between the base of the 

 wing and the intradiscal line, two in the median space and three beyond 

 the extradiscal line, in addition to the wavy submarginal. 



The median area is limited outwardly by a dark shade, which follows 

 an unusual course ; it is directed inwardly from the costa to the subcostal 

 vein, then curves outwardly to vein two, and then with a sunilar curve to 

 inner margin, which it meets three fourths out from base ; there is a long 

 black dash on the median vein, and another on vein two. 



The lines on the fore wing seem to be continued across the hind 

 wing, but are only evident on its inner margin, except the fine wavy, white 

 submarginal line, which can be traced completely across the wing. The 

 central portion of the hind wing is quite without markings. 



Beneath the fore wing is very lightly scaled ; there are three dark 

 spots on the costa, alternating with three pale spots, the central dark spot 

 being exactly above the discal spot. There is a fourth dark spot on the 

 costa, near the base, and a fifth near the apex. Submarginal space slightly 

 darker, with the pale submarginal line faintly indicated. 



Hind wing more heavily scaled, gray, crossed by about five brown 

 lines complete across wing, rhe first and third extradiscal being heavy and 

 diffuse ; discal points brown, minute. 



This species bears a slight superficial resemblance to the European 

 E. nanata, but has much narrower wings, and a different arrangement of 

 lines. 



The type specimen, a male, is unique at present, and was captured 

 by my good friend, Mr. F. H. Wolley Dod, above Agnes Lake, near 

 Laggan, Alberta, at an altitude of 7,200 feet. It is dated 17 VIII, '07. 

 The captor has very generously left it in my collection.
