2696. I draw attention to my papers in Can. Ent , Vols. IX. and 

 XI. I believe the three forms here cited to be distinct. I refer 

 tortricina to Spragueia. Fruva fasciatella and obsoleta appear to 

 differ in the structure of the front as well as in ornamentation. 

 The Californian acerba is nt2iX fasciatella. I do not know who is 

 responsible for the present jumble. If these forms are not kept 

 separate they will inevitably be described over again.

 to tip of wings 17 mm.; greatest width acri^ss closed wing-covers, 3.5 mm.

 hiptinctata (DeG.), but the outline of the closed wing-covers is more 

 elongate.

 joint short ; second yi longer ; third slightly longer than second, obliquely 

 truncate at tip and very slender at base. Eyes reddish-brown. Antennee 

 filiform, almost as long as the body ; all the joints except basal two 

 alternately equal in length up to 20th joint (except also the fifth, it being 

 slightly elongate), i2-i5th joints not elongated. First basal joint with a 

 broad longitudinal black stripe on the inner side beneath, and a slight 

 trace of a brownish horizontal line near the apex on the outside ; second 

 joint with two longitudinal parallel black lines beneath. This joint and 

 those following have each at their apex, beneath, a brown line.
