This species is smaller than rar/onotella, Ciist., which it greatly 

 resembles. The chief points of difference (which are uniform through 

 the series) are to be found in the extension of the pale ground-colour 

 to the costa betw^een the basal patch and the first fascia, in the 

 attenuation of the first fascia towards the doi'sum (whereas in 

 rarjonoteUa it is there somewhat dilated) and generally in the less 

 clearly defined limits of the darker and paler portions of the wing. 

 Indeed, in the first two particulars it approaches more closely to 

 luctuosella. Dp., but in regard to the third it differs from it quite as 

 much as from 7'ar/onoteUa, moreover in luctuosella the white, or 

 yellowish white, bands are distinctly narrower than in rrducfn, and 

 the hind-wings are less gradually attenuated to the apex. In size it 

 is perhaps hardly larger than lucfuosella, but it could scarcely be 

 mistaken for that species through the absence of the distinct contrast 

 between the colours and markings which gives to the former a 

 particularly neat and compact appearance. 



BLASTOBASIS, Z. 



2303 (2). Blastobasis (?) evanescens, sp. n. 



Antennce (9) with strong pecten ; fawn-oclireous, barred above with brown. 

 Palpi, terminal joint about half the length of the median ; pale fawn-ochreous. 

 Head and thorax pale fawn-ochreou3. Fore-tvhigs narrow, elongate, about four 

 times as long as wide ; pale fawn-ochreous, with a dusting of faintly browni.sh scales, 

 d slight indication of a brown spot in the fold at a little beyond one-third from the 

 base, with a few collected brown scales above and beyond it on the disc, followed by 

 a more clearly defined spot at the end of the cell, this sprinkling of brown scales 

 .being somewhat more profuse beyond than before it ; cilia pale fawn-ochreous. Exp. 

 al., 16 mm. Hind-toings i-ather shining, fawn-greyish ; cilia pale fawn-ochreous. 

 Abdomen and legs pale fawn-ochreous. 



Type, 'i (84150), Mus. Wlsm. 



Hah. : Corsica, Vizzavona, 12, VI, 1899. Unique. 



A somewhat abnoriiial form, agreeing with Blastobasis in having 

 only seven veins in the hind-wings, but differing in the remote origin 

 of 5 from 3-f 4. 



In the absence of the ^ I cannot venture to describe it as the 

 type of a new genus.
