NEW BRITISH SPECIES IN 1854. 69 



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 VOJE, 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. ceruseUa. 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. ceruseUa : " 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 lias most resemblance 

 to E. Kilmunella and atricomella; from the former it may 

 be distinguished by the first fascia going obliquely outwards 

 from the costa, and by the posterior position of the dorsal 

 spot; the latter is also the best character to distinguish it 

 from E. atricomella, which is a blacker insect, without the 

 lossy appearance of E. Poce. 



Alis anticis ?iitidis fuscis, pone medium saturatioribus, fascia angulata 

 ante medium, maculis oppositis pone medium {dorsali posteriori) albido- 

 luteis, obsoletis. Exp. al. 4£ lin. 



Head, face, palpi and antennae fuscous. Anterior wings shining ding;/ 

 fuscous, darker beyond the middle ; before the middle is a slightly angu- 

 lated obscure pale fascia (going obliquely outwards from the costa);
