THE ENTOMOLOGIST. 379 
none of our continental friends seem able or willing to 
recognize the distinction between these species. 
Entomologist to the Royal Agriculturist Society.—This ap- 
pointment is proposed: I sincerely hope that on the occasion 
those who have it in charge will waive all those qualifications 
of poverty, number of children, relationship, clanship, 
interest, &c., which govern the appointment of beadles or 
curators of museums, but select the man whose knowledge of 
the Science will do most honour to his appointment, and 
render the greatest service to the Society, and through the 
Society to the agricultural interest.

Life-history of Lithostege griseata.—This moth seems to 
be local as regards England, having only been noticed near 
Brandon in Suffolk, and near Thetford in Norfolk. It flies 
during June, and has been observed during every week in 
that month laying its eggs on Erysimum cheiranthoides 
(worm-seed treacle-mustard). For a first knowledge of its 
economy we are indebted to that excellent observer Mr. 
Brown, of Cambridge, previously to whose discovery the 
larva was unknown. The young larva is hatched about the 
end of June, and may be found feeding during the whole of 
July, and entering the earth in order to undergo pupation at 
the end of that month. Its chief and favourite food consists 
of the seed-pods and seeds of the Erysimum, but it will also 
occasionally eat the leaves and flowers, as well as feed on 
Sisymbrium Sophia (pin-leaved hedge-mustard or flix-weed, 
unless, indeed, this name has been given by mistake), 
Sisymbrium officinale (common hedge-mustard), and Capsella 
Bursa-Pastoris (common shepherd’s purse): these two last- 
named I have found acceptable to its taste in confinement, 
although I am not aware that it has ever been found eating 
them when at liberty. The mode in which it operates on the 
long pod of the Erysimum is curious: it begins nibbling the 
pod just below the dumpy undivided stigma (which, in the 
numerous specimens before me, is invariably left untouched), 
and eats its way down one valve of the pod, consuming every 
seed in its downward progress, leaving the median septum, * 
as well as the opposite valve of the pod entire; arrived at
