closely with this genus, far more closely than with the genus 
Pygsera in which it is placed by Dr. Harris, who had probably 
overlooked the remark made by Mr. Westwood (Drury’s Exotic 
Entomology, vol. ii, p. 28) that from the structure of the larva 
this insect “ is nearly allied to Ptilophora and Petasia, and not to 
Pygsera.” Mr. Westwood accordingly places our insect, though 
with a query, under the genus Petasia. His specimens of the 
larva, however, in being wholly denuded of hairs, misled him in 
one character of some importance, the larvae of Petasia being 
destitute of hairs. And not to mention other marks of more or 
less moment, as from the full descriptions above given these 
marks will be sufficiently obvious to professed entomologists, 
who are the only persons that will be interested in this topic, I 
may observe that in being destitute of any hump or protuber¬ 
ance upon the back of the last segment of the larva, our insect 
differs from both Petasia and Lophopteryx. Indeed it does not 
appear to find an exact representative in its preparatory and 
perfect states, in any European species, and its arrangement, 
therefore, in any of the genera which have been instituted is pal¬ 
pably incongruous. I am hence obliged to propose a new genus 
for this insect, which, in allusion to the bright orange or tawny 
yellow color of its head and the anterior part of the thorax, may 
be named Eumetopona (eu beautiful, p-et-witov front). In a system¬ 
atic arrangement of this group this genus will 6tand next to Lo¬ 
phopteryx. 
As the works of this insect are i evil only and that continu¬ 
ally,’ and as the worms are so easily destroyed by cutting off 
the twig on which they are clustered and throwing it into the 
fire, whenever a brood is met with it should be exterminated at 
once. Hens do not appear to relish them, 
Eating irregular notches in the margin and holes in the middle of the 
leaves, in June and September; a rather thick cylindrical light green 
worm an inch long with five white lines and numerous white dots. 
The Apple siiouldeu-striped Tohtrix, or the Many-dotted Apple- 
leap worm, Brachytania Malaria, new species, (plate 8, fig. 5.) 
There are many other kinds of worms in addition to those 
which we have already spoken of, which feed upon the leaves
