DESCRIPTION OF EUPITHECIA FLETCHERATA, A 



GEOMETRID MOTH FROM OTTAWA, 



NEW TO SCIENCE. 



By Geo. W. Taylor, Wellington, B.C. 



This moth is one of many interesting Geometridae that have 

 been sent to me by Mr. C. H. Young, and I propose to describe 

 it as a new species in the Naturalist in order that the attention 

 of the Ottawa entomologists may be directed to it, and that the 

 record of Mr. Young's success as a collector ot rare species ot 

 Geometridse may stimulate others to activity in this somewhat 

 neglected field. The Ottawa list in this family is growing apace 

 by reason of Mr Young's industry, and every box he sends me 

 contains some surprise in the shape of species that have not before 

 been taken in the district. 



EUPITHECIA FLETCHERATA, n. Sp. 



This is one of the broad-winged, medium-sized species of 

 Eupithecia, in wing shape much like Eupithecia latipennis Hulst 

 (which is quite common in Ottawa in the month of June), but is 

 a trifl i smaller. Expanse, 21 mm. 



Palpi of moderate length, rather bushy, very dark (nearly 

 black), with the extreme tips white. Front dark grey, with a fine 

 black transverse line in front of the base of the antennae. 



Thorax grey, darker in front ; a small white posterior tuft. 

 Abdomen dark smoky grey ; last segment darker, but in the male 

 with a tuft of snow-white hairs seen only when the last segment is 

 exserted ; dorsal tufts black ; a black lateral line. 



Beneath, the pectus is white; the abdomen pale except the 

 last segment which is dark grey ; the legs are pale, except the 

 tibia? and tarsi of the 1st pair, which are dark with pale rings. Fore 

 wings rather dark grey, with blackish cross lines enlarged on the 

 costal margin. 



The basal and intradiseal lines, with at least two intervening 

 lines, are parallel to each other ; they leave the costa at a sharp 

 angle, turning at right angles when they reach the cell and run- 

 ning in an almost straight line to the inner margin ; they are all 

 farther from the base at the inner margin than at the costa.
