106 THE ENTOMOLOGIST. 
and throughout all the correspondence about the potato bug, 
I have been silent; I have not cried “ Wolf,” simply because 
I do not believe the wolf is coming. The editor of the 
‘American Entomologist’ informs us that there are “at least 
a dozen different species of potato bug :” these are principally 
of the genera Lytta and Epicauta, beetles very nearly related 
to the familiar blister-beetle, Lytta vesicatoria. The more 
destructive, or more noticed, are Epicauta marginata, 
E. lineata, E. strigosa, EK. murina, and especially, E. atrata. 
The Count Dejean, with his usual fertility of name-giving, has 
multiplied these names, but whether he has discovered new 
species I will not venture to say. All these beetles, when in 
the perfect state, devour the potato-haulm with a rapidity 
and voracity that appears almost incredible, leaving the bare 
stalks standing up like stag’s-horns. Next in importance are 
the various species of Chrysomela, or bloody-nosed beetle, 
and entomologists incline to place the Chrysomela decem- 
lineata of Thomas Say at the head of them for mischief; the 
larva is even more voracious than the perfect insect: both 
devour the haulm, and the haulm only. The third family of 
potato-beetle comprises the genera Cassida, Cryptocycla, 
and Chelomorpha (tortoise beetles), the larve of which are 
beset with prickles in a very curious fashion: all these 
beetles are leaf-eaters, and if 1 may take the statement of our 
friends in America they are potaio-leaf eaters. It will be 
hardly necessary to state that I have no practical acquaint- 
ance with any of these beetles, except as preserved in’ 
cabinets, or that I see small prospect of their crossing the 
Atlantic; but stil when I recollect that Pieris Rape has 
already crossed in a contrary direction, I can by no means 
deny the possibility of such an event; and, therefore, I will 
give my English readers an opportunity of studying the 
remedies which our transatlantic friends think they have 
found most efficacious.— Edward Newman. 
“Artificial Remedies: Paris-green.—The many entomolo- 
gists and agriculturists who have experimented on this 
insect—with various poisons and other substances, in those 
portions of the United States where it has been so destructive 
for some years past—concur in recommending the use of 
Paris-green diluted with flour, ashes, or air-slacked lime, as 
the best remedy known for destroying the insect both in its
