fcssor Zellerliad written a little treatise on this group in the Stettin, ent. Zeitang 

 for 1871, and had differentiated the two species exactly as Mr. Barrett had done. 

 The name ccBsiella should now be dropped and not retained for either species — one, 

 feeding on hawthorn, being the oxyacanthella of Duponchel and Zeller ; the other, 

 feeding on sloe, being the spiniella of Htibner and Zeller. 



Of Swaminerdamia oxyacanthella, Mr. Barrett writes : " The larva is dai-k red- 

 " brown, with a broad spiracular stripe, which is yellow from the head to near the 

 " middle and thence reddish to the extremity, no dorsal line, lives in a white web 

 " singly, in an angle of the twigs of hawthorn. Beginning of June. Imago first 

 " emerged June 26th, all others being then in the pupa state." 



Of Swammerdamia spiniella he writes: "The larva reddish-brown, wiY/t a broad 

 " ill-defined pale dorsal line, and a broad yellowish-iuliite spiracular stripe. The 

 " dorsal line in full grown larvse is not always continued to the anal extremity, but 

 " is always very distinct towards the head and anterior segments. On black- 

 " thorn, in a similar loose web to the other, but often two or three larvae in one web. 

 " Middle of June to end. Imago emerged July 7th." 



Mr. Barrett adds " these distinctions were perfectly constant. I had a fair 

 " number of the hawthorn larvse, and found those of the other species in great 

 " abundance on blackthorn. These latter were still feeding when the hawthorn 

 " species was in pupa and emerging." He says also, that he " took the hawthorn 

 " species in great abundance at Llanberis — only among hawthorn." Spiniella " was 

 " afterwards plentiful everywhere amongst blackthorn." 



In the eleventh volume of the Natural History of the Tineina, I have confused 

 these two species as the sexes of my S. ccesiella — see p. 70—" Thorax white in the 

 " male, grey in the female." Spiniella has the thorax white, oxyacanthella has it grey. 



Zeller, in the Stettin. Ent. Zeitung, 1871, p. 75, points out the differences of the 

 two larvae, laying stress on the identical characters mentioned by Mr. Barrett. 



Everything would therefore seem perfectly clear and distinct, only, unfortunately, 

 I have on several occasions bred what appears to me to be spiniella from a haicthorn 

 hedge, in which there is not an atom of sloe. The problem now will be to try and 

 find the two larvae on this same hedge and to separate them and breed the two 

 distinct species. — H. T. Stainton, Mountsfield, Lewisham : \2th December, 1878. 



Occurrence of Swammerdamia nanivora in Russia. — During a recent visit of 

 Baron von Nolcken to this country I was much pleased to see in one of his boxes three 

 specimens of S. nanivora, of wliich I had previously only seen the single specimen, 

 which I bred, in 1870, from a larva found, in Strathglass, by Dr. Buchanan White, on 

 JBetula nana, and which was briefly noticed in the Entomologists' Annual, 1871, p. 

 96. Bai'on von Nolcken captured his specimens, on June 8th, 1878, in Esthonia, in 

 a mossy bog, among Betula nana. The size and distinctness of the sub-apical costal 

 spot was well seen in the Baron's specimens, and Mr. Eagonot, who had an oppor- 

 tunity of seeing them during von Nolcken's stay in Paris, also noticed this character. 

 It will be remembered, however, that the species was established mainly on the broion 

 larva being so different from the gj-een larva of the ordinary birch feeder, our ^rjseo- 

 capitella, the Heroldella of German authors. — -Id. : January, 1879-
