DESCRIPTION OF AN HITHERTO UNACKNOWLEDGED SPECIES OF 
SCOPARIA (S. ULMELLA, DALE, M.S.).

ScoPAEiA ULMELLA, Dale, M.S. 
Al(S anticcB angust<s, apicihtis suh-acutls, costis suh-arcuatis ; pallidce, 
fusco nigroque sparsim irroratcs ; lined prima arcuatd, late fused ; stigmate 
orhiculare suh-ohsoleto ; stigmate clav if or mi lined primd confiiso ; stigmate 
reniformi perspicuo, 'ii-formi, flavido-ochraceo, fusco marginato ; lined 
secundd costam versus quasi ^- for mi, deinde serrafd, ad onarginemque 
internum oblique deflectd ; umhris sub-ferminalibus inconsjjicuis ; margi- 
nibus apicalibios strigis punctisque sex vel septem notatis. Posticce albidce, 
nitidcB, sub apicem leviter emarginatce. Exp. alar. lin. 8. 
From the members of the dubitalis {pyralella) gi'oup, to which 
upon the whole it perhaps bears the 
greatest affinity, ^S*. ulmella is distin- 
guished by the slender conformation 
of its fore- and hind-wings. 
The peculiarity of its renal stig- 
ma, 0-shaped and filled in with ochre- 
ous, at once separates it from the 
mercurella group. ^.c^. 
To the COarctata group it bears Scoparia ulmella, Dale, M.S. 
some resemblance in the form of the fore- and hind-wings, but it has 
little else in common ; the characters of the first line and its appurte- 
nances, &c., forbidding any connexion with that group. 
It will therefore be seen that >S^. ulmella has a facies peculiar to 
itself, of which the most striking points are the long narrow fore-wings 
with slightly acute apices — the well-defined broad arched (concavely 
facing the base) first line, in which two of the stigmata are pretty 
nearly absorbed — the very characteristic renal stigma, 8 -shaped and 
filled in with ochreous — the apical margin furnished with dots and 
dashes — the shape of the hind-wings, which are comparatively long, and 
slightly emarginate just below their apices. 
Of this interesting little species Mr. Dale took three examples on 
the 13th of July, 1844, on a wych elm trunk in a thick wood at East 
Meon, adjoining Bordean Hanger (Captain Chawner's estate). One of 
these, which Mr. Dale presented to the late Mr. Curtis, is now un- 
fortunately in Australia ; the other two are in Mr. Dale's own cabinet.
