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 Eupithecia, 
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 Sawyer ;

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. Dobrée; Beverley, May 18,1875. 
Lupithecia Knautiata (Entom, viii. 38).—Is Mr. Gregson 
sure that the plant he found this species on was not Scabiosa 
succisa (Z.)? 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
