wanting. But on the basal part of the costal margin salicifolieUa has a 

 white streak, and just behind it another which meets an opposite dorsal 

 streak so as to form an angulated fascia ; and this streak and fascia are 

 absent in Scudderella. The other costal streaks are similar in the two 

 species, except that in salicifolieUa the last two, placed just before the 

 apex, usually cross the wing, becoming fascia. There are other differ- 

 ences, but those here indicated are sufficient for the ready distinction of 

 the species. 



L. deceptusella, n. sp. 



Among my captured specimens of L. cralcegella Clem. I find a speci- 

 men of this species which at the time of its capture I regarded only as a 

 variety, but which a more attentive examination convinces me is a distinct 

 though allied species. The abdomen and two hinder pair of legs are 

 wanting, though otherwise the insect is in good condition, and though 

 there is but a single specimen, I describe it for the purpose of discrim- 

 inating it from cratcegella. 



Head, antenna? and palpi silvery white, tuft white mixed with saffron, 

 much paler than in cratcegella. Thorax and fore wings very pale golden 

 brown — much paler than cratcegella, perhaps more properly described as 

 dark reddish saffron. On the fore wings there are four silvery white 

 costal streaks like those of cratcegella in shape and position, but smaller 

 and not so distinctly dark margined ; the first is about the middle of the 

 wing length, and is dark margined on both sides ; the second is behind it 

 and is dark margined only before, as also on the other two, which are in 

 the apical part of the wing. The dark margin of the first streak is con- 

 tinued along the extreme costa to the base. There is a short and narrow 

 white streak on the base of the dorsal margin and a median basal silvery 

 white unmargined basal streak which extends nearly to the middle of the 

 wing. (In cratcegella this streak is dark margined on both sides and 

 around its apex.) Nearly opposite to, but a little before the first costal 

 streak, is a nearly square large dorsal silvery white spot, which extends to 

 and becomes confluent with the median basal streak just before the apex 

 of the latter. It is directed a little obliquely backwards and is not at all 

 (or but very faintly ?) dark margined ; opposite to the second costal streak 

 is a triangular silvery white dorsal spot, larger than the costal spot and 

 almost an equilateral triangle. The first of these dorsal spots — the one 

 which extends to and is confluent with the median basal streak — is in
