58 THE CA.NADIAN ENTOMOLOGIST. 



The single type is a female taken at Kaslo on July 12, 1907, by Mr. 

 Cockle, and it is in his cabinet. 



3. Eiipithecia termmata^ n. sp. — This species and that next to be 

 described both belong to a group of which the commonest form in British 

 Columbia is one to which I have always applied the wd^vat perfiisca^ Hulst. 

 The species in this group are very nearly allied, and with more abundant 

 material I have already been able to distinguish four B. C. forms. 



Dr. Hulst's types oi perfusca came from Euston, Washington, and 

 from Utah, the last named type being in the United States National 

 Museum. 



They may or may not be conspecific, and as they are not now in the 

 best of condition it is not an easy matter to ascertain with certainty which 

 form has the best title to the original name. I suggest, therefore, that the 

 very common western form, to which I have limited it in my own cabinet, 

 shall be allowed to retain the i\2imQ per/us ca, Hulst. This form has been 

 identified by Dr. Dyar as conspecific with specimens so named for him by 

 Dr. Hulst, and probably with the type from Utah, and it answers as well 

 as any of its allies to Hulst's original description. If the other types in 

 the Hulst collection prove to differ they may be given a new name. The 

 true E. pei-fusca as thus restricted (type from Utah and B. C. specimens) 

 can be distinguished from the other species of the group by a broivn shade, 

 which in fresh specimens is distinctly visible at the junction of veins 3 and 

 4 of the fore wing. This is easily seen in all of the 30 specimens before 

 me at the present moment. 



EupitJiecia terviinata may be described as follows : 



Expanse, 25 mm. Very closely allied to E. perfiisca^ but it is a little 

 larger and considerably darker in colour. The palpi (in terminatn) are 

 distinctly longer, the brown shade at the junction of veins 3 and .4 is 

 absent. 



The most easily-noted difference is, however, in the hind wings. In 

 E. terminata these are rather heavily dusted with black scales, especially 

 towards the outer margin, where they give the appearance of a wide sub- 

 marginal dark band. This band is not intersected by the usual white 

 submarginal line, which can be traced in perfiisca, but there is a very 

 slight indication of a white dot submarginally in the neighbourhood of 

 vein I. The margins of the hind wings are not so noticeably depressed 

 at vein 5 as \u per/usca.
