brownish and white scales. The costa is slightly geminated with white from 

 the basal patch to the tip of the wing, with intermediate blackish brown 

 stripes, one of which is extended to the hinder margin beneath the tip. Hind 

 wings dark fuscous. 



Mr. B. D. Walsh, to whom I am indebted for a suite of specimens, 



says respecting its larval life, that " it mines a gall like a rose, on a 



dwarf upland willow, Sali.r humilh, which I call salicis rhxIoldcK^ and 



swarms in it, several being found in each gall. I have bred over a 



hundred, but, as is the case with the other specimens sent herewith, it 



varies but little, I send only a few." The larvae are found from Aug. 



1st to the 24th. 



Hedya saliciana n. s. — Fore wings brown, slightly testaceous, marked with 

 white clouded witli brownish. The basal patch has its posterior edge strongly 

 angulated. The central fascia is often illy marked, oblique and of the general 

 hue. Between the central fascia and the basal patch is an angulated band 

 which is whitish on the inner margin and towards the costa is clouded with 

 brownish or testaceous-brown ; the apical portion of the wing is of the same 

 hue as the central band and is varied with brownish, and at the ocelloid patch 

 with a few black stripes. The costa is slightly marked with white from the 

 basal patch. 



Variety a. The ornamentation is the same, except that the basal patch is 

 reddish-brown and the wing exterior to the basal patch is suffused with dark 

 reddish, leaving however on the middle of the inner margin a whitish patch 

 more or less sufl'used with reddish. 



Variety P. The basal patch is dull reddish-brown and the wing exterior to it 

 is nearly uniform ochreous-gray, without distinct markings. 



Mr. Walsh informs me that H. saliciana mines a cabbage-like gall 



peculiar to Sa/ix loiigif<jlia. Variety «, mines a pine-cone-like gall on 



Salix cordata, and I suppose variety fi inhabits the same gall. 



DITULA ? 



Costa broadly folded, closely aj^pressed and rounded. Apical vein of fore 

 wings simple. Antennae ciliated, not subserrate and plumose. 



Ditulal blandana n. s. — Fore wings reddish ochreous, with the central fascia 

 reddish-brown, oblique, and somewhat diffuse beyond the middle of the wing. 

 On the costa exterior to the central fascia, is a conspicuous, triangular white 

 spot, having on the side next the hinder margin a rounded, reddisli brown 

 spot projecting into the costal white spot. The whitish portion of the wing, 

 exterior to the central fascia is striated with redtlish-brown. Hind wings pale 

 fuscous. Head and labial palpi reddish-ochreous. 



A single specimen, not in good condition, from A. S. Packard, Jr. 



of Brunswick, Maine.
