70 LEPIDOPTERA. 
beyond the middle are two yellowish-white opposite spots, of which that 
on the inner margin is rather posterior; both are frequently excessively 
indistinct; cilia, beyond a dark hinder marginal line, greyish-fuscous. 
Posterior wings greyish fuscous, with paler cilia. 
The female is larger, expanding lines, and the fascia and spots are 
more distinct. 
ELACHISTA GREGSONI, Stainton, n. sp. Bred by 
Mr. C. S. Gregson from black-headed, greenish-grey larvae, 
found in a species of Poa near Liverpool last March. 
It is closely allied to E. nigrella, but the larva is very 
different, and in the female the two opposite spots are more 
exactly opposite.

Exp. al. 3£ lin. 
Head greyish fuscous. Face and palpi whitish. Antennae dark fus¬ 
cous. Anterior wings blackish, with a slender whitish fascia before the 
middle; two opposite spots beyond the middle, and the extreme ape* 
whitish; these markings are, however, very indistinct; cilia, beyond 
a dark hinder marginal line, pale grey. Posterior wings grey, with 
paler cilia. 
'Jhe female has the anterior wings black, the basal portion only a little 
paler; the first fascia nearly straight, and the opposite spots, which are 
very distinct, almost form another straight fascia. 
LITHOCOLLETIS VACCINIELLA, Scott, n. sp 
The larva was discovered last May by Mr. Scott at Focha¬ 
bers, Banffshire, and Mr. Weaver in Perthshire, mining 
the underside of the leaves of Vaccinium Vitis Idcei, and 
the perfect insect was bred the following month. It is 3 
brilliant species, reminding one of L. pomijoliella and l 
Lantanella, but readily recognised by the total absence d 
any white scales on the inner margin of the anterior wing 5 '- 
between the base and the first dorsal spot.
