SWAMMERDAMIA CICSIKI.I.A. [PlATE IT. FlG. '2. 



Geographical Distribution. 

 Tliis species seems very geuerally 

 distributed throughout England, and 

 has also been noticed in Scotland 

 and in Ireland. M. Constant enu- 

 merates it amongst the species oc- 

 curring in the department of Saone 

 et Loire, and Biuaud enumerates it 

 in the sj^ecies occurring in the de- 

 partment of Doubs. In Germany it 

 has been noticed in various localities; 

 but it is naturally very difficult some- 

 times to say whether the species re- 

 corded has been the hawthorn-feeder 

 or the birch-feeder. It is also re- 

 corded as occurring in Switzerland 

 and in Italy. 



Synonymy. 

 This insect was lirst figured by 

 Hiibner recognizably at figure 360 

 (erroneously numbered 260) in his 

 " Sammluug Europuischer Schmet- 

 terlinge," as Tinea ccesiella; he 

 there represents the two white costal 

 spots and the white inner margin 

 characteristic of the males of the 

 present species ; his previous figure 

 under the same name, 172, is so bad 

 that it is best to omit all reference 

 to it. Ilaworth appears to have 

 had this insect in view when he 

 spoke of his var. y. of his Erminea 

 lutarea, in the 4th part of his " Le- 

 pidoptera Britannica." Treitschke 

 probably had specimens of this insect 

 before him when he described the 

 imago of his Lita Heroldella, in 

 the 9th volume of his " Schmetter- 

 linge von Europa ;" but the de- 

 scription of the larva, as already

La Distribution Geographique. 



Cctte espcce parait etre trcs-re- 

 jiandue partout en Angleterre, et se 

 trouve aussi en Ecosse et en Irlaude. 

 M. Constant la cite parmi les especes 

 qui se trouvent dans le departemeut 

 de Saone et Loire, et Bruand la 

 conte parmi les especes du departe- 

 meut de Doubs. En Allemagne on 

 I'a remarquee en plusieurs localites, 

 mais quelquefois il est assez difficile 

 a decider si I'espece dont on parle 

 est I'espece de Faubepiue, ou celle 

 du bouleau. On dit aussi qu'elle se 

 trouve dans la Suisse et en Italic. 



Synonymie. 

 Hiibner a le premier figure cet 

 insecte en fa^on reconnaissable sous 

 le nom de Tinea ccesiella a la figure 

 360 (par erreur imprimee 260) de sa 

 " Sammlung Europiiischer Schmet- 

 terliuge ;" il represente les deux 

 taches costales blanches, et le bord 

 interne blanc, qui sont si caracteris- 

 tiques des males de notre espece ; la 

 figure 172 qu'il avait deja publiee 

 avec le meme nom est si mauvaise 

 qu'il vaut mieux de n'y pas penser, 

 Haworth parait avoir eu cet insecte 

 sous les yeux en parlant de la 

 variete y. de sou Erminea lutarea 

 dans la (juatricme partie de ses 

 " Lepidoptera Britannica." II est 

 possible (jue Treitschke ait eu 

 devaut lui des individus de cetle 

 espcce lorsqu'il a fait la description 

 du papillon de Lita Heroldella, 

 dans le neuvieme volume de ses
