Riley. I have critically compared the former with the description 

 of the type,* and find it to agree in every particular, even to dimen- 

 sions, so that there can be no doubt of their identity. 



Mr. Stretch remarks : " For the type of this species I am indebted 

 to the kindness ot Lord Walsingham, who captured the single speci- 

 men above referred to in Oregon, during his recent trip to the 

 Pacific coast. In form it approaches nearest to E. egle^ from which 

 it differs iiot merely in the color of the wings, but also by the slen- 

 derer Mbdomen and the bright yellow head. Were it not for these 

 latter differences, it might be considered an albino of ^E". egle, though 

 the typical form of that species is yet unknown from the Pacific 

 coast." 



I fully concur with Mr. Stretch in his recognition of this form, as 

 distinct from E. egle. In addition to other important differences, in 

 both of these eastern examples, the long, slender, cj^lindrical abdomen 

 is in marked contrast with the short (from A in. to .5 in.), thick and 

 conical form observed in the male of E. egle. 



Of the albino form of E. egle^ referred to by Dr. Packard f and 

 Mr. Riley, X and accepted by Mr. Stretch upon the testimony of 

 "eastern entomologists," I have no knowledge. I believe that all 

 such examples of " a white variety," will, on critical examination, 

 resolve themselves into E. collarls (Fitch), or E. Oregonensis. 



In consideration of this new habitat of Oregonensis^ the name 

 selected for it proves to be an unfortunate one; it also presents an 

 argument against the derivation of specific names of insects from the 

 locality of their first observation, especially while so small a portion 

 of our continent has been thoroughly explored,§ our knowledge of 

 geographical distribution so very limited, and the necessary compari- 

 son of our fauna with that of Europe not yet made.||

§ In a recent paper on the Phalajnidae of California, in which thirty-three new 

 species are described, ten of the number bear the name of Calif or nidria or Galifor- 

 niata. • It is hardly possible that all of these species will prove to be peculiar to that 

 Stale or even to the Pacific slope, for more extended observations are continually 

 showing us the identity of many of the species of the Pacific coast with those of the 

 Atlantic States. 



I The species described not long since as Depressaria Ontariella from Canadian 

 examples, proves not only to be a common species in the State of New York, but 

 identical with the Tinea h^radeana of Europe, described by De Gcer more than a 

 century ago.
