THE ENTOMOLOGIST’S 
WEEKLY INTELLIGENCER.

THANKS. 
Stx weeks have scarcely elapsed since 
our last appeal to our correspondents 
on the subject of the genus Depres- 
saria, and already three species never 
bred before by us grace our setting- 
hoards. 
Our most especial thanks are due to 
those who have thus promptly responded 
to our call. 
Firstly, we have to thank Herr 
Schmid, of Frankfort-on-th e-Main, for 
a new species in the genus, the larva 
of which feeds on yarrow ( Achillea 
millefolium ) ; the perfect insect is inter- 
mediate between Albipunctella and Pul- 
cherrimella , and belongs to a group 
which we have hitherto been accus- 
tomed to consider exclusively Umbel- 
lifera-e ating insects ; for this novelty 
the name of Depressaria Achillea: has 
been proposed. 
Secondly, we have to thank Herr 
Hofmann, of Ratisbon, for the larva 
of D. Pallorella: this larva, like its near 
ally D. Liturella, feeds on the leaves 
of Cenlaurea, but its dark green colour 
readily separates it from the black 
larva of Liturella; moreover, that is 
fed up at the end of May, this at the 
end of July. Rumours had indeed 
reached us that Pallorella was a Cen- 
taurea- feeder, but we fancied there 
was some confusion with Liturella , and 
were not disposed too hastily to give 
credence to the assertion. 
Thirdly, we have to thank Herr 
Lederer, of Vienna, for transmitting 
to us living larvae and pupm of the 
Alpine species Depressaria ILeydenii. 
This insect was first noticed by Senator 
vou Heyden, who, turning over a stone 
on the Faulhorn, in August, 1847, met 
with a pupa spun up thereto, which 
produced a specimen of a new Depres- 
saria ; this was named by Zeller after 
its discoverer, and the unique specimen 
was fully described in the ninth volume 
of the ‘ Linnaea Entomologica.’ In the 
summer of 1858 Professor Zeller visited 
Vienna, and made an excursion to the 
Styrian Alps; there he found a De- 
pressaria larva in abundance on a white 
Umbellifer, and collected a considerable 
number, but the plant went mouldy 
whilst he was travelling, so that all the 
larvae perished but two, which pro- 
duced D. ILeydenii. One of these was 
forwarded for verification to Senator 
von Heyden, and when at Frankfort 
last May we had an opportunity of 
comparing this Styrian specimen with 
the original Swiss individual, and 
agreed with the learned entomologist
