282 THE ENTOMOLOGIST. 



August" (Id.). Mr. Stainton says (E. M. M. ii. 187), "I have 

 only a single bred specimen of dichrodactylus ; this was bred from 

 a ;pupa on tansy at Chudleigh, in June, 1850, and which appeared 

 in the perfect state July 5th." The late Mr. Buckler bred this 

 insect from June 28th to July 5th from larvae received from 

 Mr. Sang, June 8th (c/. E. M. M. xii. 233). The larvse sent me 

 by Mr. Sang in 1882 were feeding in June, and the moths 

 emerged in July. Then as regards hertrami I have bred it, as 

 stated above, in July, from June larvse ; and Mr. Porritt bred his 

 Jirst specimen on July 24th, from larvse received June 25th (c/. 

 E. M. M. xxii. 105). In a state of nature I have met with this 

 insect from the end of June to the end of July. 



From these facts it does not appear that dichrodactylus is a 

 later insect than hertrami; but, on the contrary, they tend to 

 prove that the two insects are synchronous. 



In all reference to the tansy-feeding insect I have used 

 Muhlig's name, dichrodactylus, to save confusion ; but it should 

 be remembered that the prior name is ochrodactyla of Hiibner ; 

 and if it is ultimatel}^ conclusively proved that hertrami is not 

 distinct, then Bossier's name also will be sunk, and the 

 synonymy will stand thus : — 



Ochrodactyla, Hiibner. 

 dichrodactylus, Miihlig. 

 hertrajiii, Roessler. 



Lord Walsingham, in his remarks on P. hertrami (' Ptero- 

 phoridse of California and Oregon,' p. 4), observes that the late 

 Professor Zeller was inclined to consider hertrami, ochrodactyla 

 {= dichrodactylus) , and hisclioffii as all belonging to the same 

 species. The last named is a Texan insect, and I have not seen 

 it; but as regards hertrami and ochrodactylus I quite concur in 

 the opinion entertained by the late Professor.

RHOPALOCERA IN THE NEW FOREST. 



By F. W. Hawes. 



On July 18th, in company with my brother, in pursuit of 

 improved health and entomological specimens, I started for 

 Lymington, which we found a convenient place for working the
