several of which are margined by black scales; cilia of the costa pale 
yellow, of the hinder margin fuscous, with a black apical streak. Pos¬ 
terior wings pale grey, with paler cilia. 
ELACHISTA POJE, Douglas, n. sp. The larva is not 
uncommon in the leaves of Poa aquatica in April and 
August, but is very apt to be ichneumoned. The mined 
places are very long and narrow, and only slightly disco¬ 
loured; thus very dissimilar to the broad whitish mines 
| made in the leaves of Arundo phragmites by the larva of 
E. cerusella. The first notice that appeared of this insect 
was in the Zoologist for 1853, at page 4142, in an observa¬ 
tion by Mr. Miller “ On the habits of E . cerusella the 
| insect having been mistaken by Mr. Miller for the other 
sex of E. cerusella; a mistake not unnatural, when we con¬ 
sider the simultaneous appearance of the two species in the 
same localities. Mr. Douglas found the larvae in Green¬ 
wich Marshes in August, 1853, but all the specimens then 
found were ichneumoned. Last spring it was found at 
Southend, Greenwich, Hackney, &c., and, no doubt, is 
generally distributed, though hitherto so completely over- 
| looked. 
It is an obscure dingy insect, and has most resemblance 
,0 E. Kilmunella and atricomella; from the former it may 
lie distinguished by the first fascia going obliquely outwards 
from the costa, and by the posterior position of the dorsal 
8 P°t; the latter is also the best character to distinguish it 
from E. atricomella , which is a blacker insect, without the 
glossy appearance of E. Poce.
