THE ENTOMOLOGIST. 133 



several letters from correspondents suggesting to me the 

 probability of its being an odd specimen accidentally 

 imported. The species may have been imported by some of 

 the numerous Black Sea and Baltic steamers trading to Hull. 

 I think it highly probable it has been so introduced. But 

 when } The fine condition of the specimen I took leads me 

 to believe it has been bred in this country. The Eupilheciae, 

 generally, are not addicted to roaming; but even if this 

 specimen was an exception it could scarcely have travelled a 

 considerable distance from the nearest steamer without damage 

 to its plumage. The coming season will no doubt show 

 whether the species is established on the ground, or the 

 specimen I have to be a solitary wanderer. — James Saivyer ;

Eupithecia extensaria (Entom. viii. 108). — It is sufficient 

 to know Mr. Sawyer to be assured that this recorded capture 

 is in every sense a genuine one, so far as he is concerned ; 

 but steam is slowly working a revolution — even in Entomo- 

 logy : Livonia is practically now as near to us — especially to 

 Hull — as the Continent is to the South Coast of England, 

 for steamers trade weekly direct to Revel, Pernau, and Riga, 

 bringing large cargoes of hemp, flax, linseed, and grain. The 

 Russian peasant sends his produce to market in a dirty state, 

 especially grain and linseed, largely admixed with weeds and 

 rubbish. What more likely than that E. extensaria, in the 

 egg or pupa state, has been brought over in this way ? and 

 the probability is strengthened by the locality of the capture 

 being within a mile or two of the dock warehouses where 

 these steamers chiefly discharge. This capture is, I believe, 

 a solitary one, and unfortunately the spot has now been 

 broken up for the extension of the dock, but there would be 

 nothing startling in its having found a domicile here, for the 

 climate is congenial. — N. F. Dohree; Beverley, May 18, 1875. 



Eupithecia Knautiata (Entom. viii. 38). — Is Mr. Gregson 

 sure that the plant he found this species on was not Scabiosa 

 succisa (L.) ? I have never seen Knautia arvensis out of 

 cornfields, whereas Scabiosa succisa is always found growing 

 in company with the common ling in heathery, sandy ground. 

 Should this be the case, would it not be better for him to alter 

 the name of the species, unless the inflexible law of priority 

 must hold its own in every case; else it might fall under the
