210 Mr. H. T. Staiiitoii on neiv species of Madeiran Lepidoptera. 



2. Acidalia atlantica, n. sp. 



A. alis anticis dilute griseis, lineis tribus e punctis nigricantibus com- 

 positis, costam versus angulatis et latioribus, puncto discoidali 

 nigro supra lineam centralem posito ; margine postico nigro pune- 

 tato. — Exp. al. Q^-7 lin. 



Allied to Acidalia Virgularia, but paler and neater ; the three 

 lines parallel, and distinctly angulated towards the costa; the 

 discoidal spot placed on the central line, and the hind margin 

 of the hind wings more dentated : the hind tibiae of the male are 

 incrassated, with no spurs, and the tarsi almost obsolete; the 

 hind tibiae of the female have one pair of spurs. 



Inhabits Dezerta Grande. 



3. Scapula fer rug alis y Hiibner. 

 Udea ferrugalis, Stephens, Mus. Cat. p. 240. 

 Inhabits Madeira proper. 



4. Simaethis Fabriciana, Linnaeus. 



Simaethis Fabriciana, Stephens, Mus. Cat, p. 248. 



Two specimens, both a trifle darker than European specimens 

 of this insect, but apparently not specifically distinct. 

 Inhabits Madeira proper. 



5. Eudorea decor ella, n. sp. 



E. alis anticis albidis, striga anteriore recta latiuscula, striga posteriore 

 tenui arcuata et indentata, externe late saturate fusco marginata, 

 signo t$ ochraceo expleto, spatio antemarginali angusto albo. — 

 Exp. al. 8 lin. 



In the sharp contrast of colour, this resembles E. resinea ; but 

 from that species it is abundantly distinguished by the form of 

 the second striga, the distinct white submarginal space, and the 

 ochreous filling-up of the mercurial marking. 



Inhabits Madeira proper. 



6. Eudorea frequentella, Stainton. 

 Eudorea frequentella, Stephens, Mus. Cat. p. 4. 



Three specimens, in bad preservation, should probably be re- 

 ferred to this species ; but in all, the central portion of the wing 

 is dark, as m the variety (?) concinnella. 



Inhabits Madeira proper. 



7. Eudorea acuminatella, n. sp. 



E. alis anticis angustis, acuminatis, dilute griseis, striga priore acute 

 fracta, extus saturatius marginatis, striga posteriore biarcuata et
