MANY-DOTTED APPLE-LEAF WORM. 241 



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 larvse 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 Ewaetopona (sv beautiful, p-erwrrov front). In a system- 

 atic arrangement of this group this genus will stand next to Lo- 

 phopteryx. 



As the works of this insect are ' evil only and that continu- 

 ally,' and as the worms are so easily destroyed by cutting oif 

 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 shoulder-striped Tortrix, or the Mant-dotted Apple- 

 leaf worm, Brachytcenia Malana, 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
