Type, (EcopJwra (Scythris) phyeidella, Z. 



Blastobasis, Z. Lin. Ent. X. 171 (1855) ; Hein. Schm. Deutsch. 

 Tin. 387 (1870). 



Zeller separated phyeidella, Z., and roscidella, Z., from Butalis 

 under the name Blastobasis, but giving only a brief indication of 

 its characters. Heinemann constituted phyeidella the type, and 

 described the genus in detail, but with hardly sufficient precision 

 for comparison with other genera now known to occur. It may 

 be well to indicate the characters peculiar to the genus Blastobasis, 

 remarking that those species which have been placed in it in the 

 North American lists do not conform in neuration. 



Antennae : 6 with pecten, strongly notched beyond the basal 

 joint, uniciliate g. 



Labial palpi recurved, of approximately equal thickness through- 

 out, second joint scarcely longer than the apical. 



Maxillary palpi short, projecting. 



Haustellum long, well developed. 



Head and thorax smooth. 



Fore tvings elongate, lanceolate, somewhat widened at the base, 

 acutely pointed. Neuration : 12 veins, 7 and 8 stalked, 7 to costa. 



Hind wings with, abdominal angle strongly developed, thence 

 evenly tapering to the subacute apex, costa much straighter than 

 dorsum. Neuration : 7 veins (4 absent) : 5 and 3 stalked (some- 

 times connate). 



Abdomen somewhat flattened. 



Leys : hind tibia? hairy above. 



89. Blastobasis abgillacea, sp. n. 



Antenna; fawn-grey (a pecten on the basal joint beneath). Palpi 

 smooth, evenly curved ; fawn-grey. Head fawn-grey. Thorax 

 fawn-grey, with a slight brownish tinge. Fore wings fawn-grey, 

 with a brownish suffusion and some greyish-fuscous mottling 

 around the apex and apical margin, a small blackish spot on the 

 cell a little before and above the middle of the wing, from which
