198 THE ENTOMOLOGIST’S WEEKLY INTELLIGENCEB. 
between tbe Druryella group and Lienig- 
iella, the paler ground-colour brown in- 
stead of black, and tbe longitudinal 
streaks at the base, causing it to approxi- 
mate to tbe last-named species. 
lu 1854 appeared my volume of tbe 
‘ Insecta Britannica,’ in which two 
British species of the genus are described, 
Drurella and Lienigiella; the former I 
then believed identical with Zeller’s 
Druryella, described in the ‘Zeituug’ of 
1850, deeming it an accidental error 
that he had described the base as brassy, 
lor in our insect, as in Hiibner’s Zieg- 
Icrella, the base is black. 
The characters of the Drurella of the. 
‘ lusecta Britannica,’ for which it is best 
now to retain the Haworthian name of 
Dxirnia, are as follows: — 
“ Anterior wings black, with an oblique 
silvery fascia near the base, a broad 
orange fascia in the middle, edged with 
silvery violet, and with two short silvery 
streaks, one at the anal angle and one 
at the extreme apex.” 
In 1856 Frey described a new species 
under the name of Schmidiella, and in 
remarking wherein it difi’ered from Dru- 
ryella of Zeller, he observed, in a note, 
that theFabrician wame Drurella might, 
on account of the insulficienl description, 
be applied with equal correctuess to 
several species, which he believed had 
actually been done, and he then proceeds 
to point out that Staiutou’s Drurella was 
distinct not only from his Schmidiella, 
but from Zeller’s Druryella. 
The essential characters oi Schmidiella 
are “ anterior wings black, the base itself 
black, then an oblique golden or brassy 
fascia, an orange fascia in the middle 
edged with golden, and with an im- 
interrufitcd blucish silvery line going from 
the anal angle to the extreme apex.” 
This continuous line occurs in Zeller’s 
Druryella, but not in the British Eximia, 
but Schmidiella differs at once from 
Zeller’s Druryella in not having the 
entire base of the wing brassy. 
Hence so far the three species are 
easily distinguished, if the specimens be 
in good condition. 
Herrich-Schaffer, in his ‘ Schmetter- 
linge von Europa,’ figures (999) and de- 
scribes a species which seems to agree 
with our Eximia; but he adds that one 
specimen from Professor Frey differs in 
having the apical streak continuous. In 
this he correctly points to the character 
which distinguishes Frey’s Schmidiella 
from our Eximia. 
The larva of Eximia mines in the 
leaves of the hop (Humulus lupulus ) ; 
frequently there are many larva in a 
single leaf. 
The larva of Schmidiella mines the 
leaves of Vicia Sepium. 
The larva of Zeller’s Druryella has not 
yet, I believe, been observed ; in the Ent. 
Zeitung, 1850, Zeller remarks (p. 19~) 
that it occurred amongst raspberry and 
hop bushes, and there is an impression 
gone abroad that it (like Eximia) mines 
the leaves of the hop. 
If we tabulate the three species above- 
mentioned, thus — 
Schmidiella. Extreme base black, 
apical streak uninterrujited. 
Eximia. Extreme base black, apical 
streak interrupted, forming two 
spots. 
Druryella, Z. Entire base brassy, 
apical streak uninterrupted. — 
we see at once that wc leave space for a 
fourth species, with — 
Entire base brassy^ apical streak in- 
terrupted, forming two spots, 
which arc the very characters of the in- 
sect which was taken by Mr. Brown,
