British Species of the Genus Micropteryx. 33 



Duponchel's figure and description are very good, but there is 

 some mystery attending his insect, as he says he received it from 

 Herr Fischer von Roslerstamm, under the name of Anderschella, 

 which is inconceivable, as rubrifasciella was not known in 

 Germany in 1 839, though Herr Mann now sends us the insect, 

 but with a manuscript name ; moreover, the true Anderschella 

 (a very beautiful species) is figured and described by Duponchel 

 as ammanella (vol. xi. 401, pi. 302, f. 8), and he says it was 

 sent to him by Herr Fischer von Roslerstamm under that name. 



Haworth's Tinea sanguinella, of which he says " preecedentis 

 (rubrifasciellce) forte varietas," does not belong to this genus ; it 

 is the Tortrix rutilana of Hiibner. Haworth's specimen is in 

 Mr. Stephen's collection. 



Sp. 6. Mansuetella, Zeller. 



Capillis atr'is ; alis anticis aureo-viridis, macula basale ad costam, 

 fascia ante medium, apiceque, rvfescentibus, obsoletis. 



Mansuetella, Zell. Funfter Bericht des Schlesischen Tausch- 

 vereins, 1844, p. 16. 



Exp. alar. 4 lin. 



Head and face deep black, almost blue black. Antennae black, 

 about half as long as the anterior wings. Thorax, abdomen, legs 

 and tarsi fuscous. Anterior wings greenish golden, with some 

 very indistinct reddish markings, namely, a costal spot at the 

 base, and a fascia before the middle, and the apical half of the 

 wing is entirely reddish ; cilia cinereous. Posterior wings pale 

 grey, with the apex purplish ; cilia cinereous. 



Mr. Douglas has two specimens which he took some years 

 back, along with Calthella. From Zeller's account the species 

 occurs near Glogau, at the same time as Calthella, on Sorbus 

 aucuparia and Spiraea ulmaria. 



It is readily distinguished from every other known British 

 species of the genus by its deep black head; but independently 

 of this character, it may be recognised by being of the size of 

 Calthella, with the markings on the anterior wings somewhat 

 resembling rubrifasciella, only more indistinct. 



Sp. 7. Subpurpurella, Haworth. (PI. III. fig. 10—13, 18.) 



Capillis cinereis ; alis anticis aureo-viridis, macula pallidiore fere 

 obsoleta ad angulum anale, posticis cinereis apicibus pur- 

 pura scentibus.
