rieties there ought to be some way of designating tlie different forms, 

 and I would thus distinguish them : 



1. Hind wiugs with one or more black dashes beneath in % 2. 



" without black dashes beneath ; fore wings without reddish band 

 above cnryse. 



2. Fore wings above with reddisli band 3. 



" without reddish hand ; liind wings with two Mack dashes. 



demotella. 



'.i. Hind wings with two black dashes beneath angunella. 



" with one only nigrosigiiella. 



1 am as certain as I can be from a description, without seeing the 

 insect, that carycevorel/a Rag. given above is also a synonynt of this 

 insect. If he had the % , and it had no dash below, then a synonym 

 of caryce ; if he had the 9 *^'ily, then of that, or of demotelht. But 

 as I have not seen the insect I give the name the benefit of what 

 doubt there is. 



7. A. riibrifasciella Pack.. Ann. Lye. Nat. Hist. N. Y. x, 267, 1873; 

 Grote, Bull. Geol. Surv. Terr, iv, 693. — Body and wings slate-ash, glistening; 

 thorax tinge^l with reddish brown and with the head giving otF faint metallic 

 colors : palpi blackish on the outside. Fore wings rather bro-ad ; just within the 

 basal third a straight line of raised scales, extending from inner edge, and stop- 

 jiing short of the subcostal vein, conspicuously black externally, concolorous with 

 the wing within ; the black line is bordered with vermillion (sometimes wanting), 

 which usually reaches the costal edge. Base of wing slightly paler than middle 

 of wing. A light triangular paler shade in the costal region of the middle of 

 the wing, enclosing the two black discal spots. A snbmarginal faint narrow line, 

 curved outward in the middle, with four or five acute scallops. Fringe concol- 

 orous with rest of wing. Hind wings pale glistening cinereous. Beneatli, fore 

 wings quite dusky with no markings; hind wings much paler, growing darker 

 towards the costa Legs dark ash, paler at the end of the joints, e.specially the 

 hind tibife, which have a whitish band around them ; hind legs whitish within 

 (Packard ). 



Dr. Packard says, " the larva lives in June and early in July be- 

 tween the leaves of the Alder (^Abnis), where it makes a hoi-n-shaped 

 case of black cylindrical pellets of excrement, arranged regularly in 

 circles, the additions being made around the mouth of the case. The 

 case is about an inch and a half long ; its mouth is a quarter of an 

 inch in diameter; within it is densely lined with white silk. 



'I'he pupa is of the usual color, mahogany-brown, the end of the 

 abdomen rounded, with six hairs projecting from a supra-anal pro- 

 jecting ridge. On each abdominal segment is a dorsal dusky trans- 

 verse strij)e, widest on the basal segment. The pupa state lasts about 

 two weeks, the moth which I reared appearing July 24th, the larva 

 having' been found Jidv Hth.'"
