 ccBsia, Hw. The larva on apple, pear, cherry and hawthorn, and probably 

 on other fruit trees, though Prof. Zeller says he has only bred it from apple. 

 It is "sulphur-yellow, with dark red-brown sub-dorsal stripes, and pale 

 reddish-brown bands on the 4th to 12th segments " (Staiuton).

 rupted brown-red line forming spots on each segment ; head yellowish- white " 

 (v. Hey den). 



Another species (Ziimnermanni, Now.), according to tlie description 

 and figure, appears to differ from the other Sioammerdamice, and has 

 been placed by Nowicki in a new genus (^Kesslerid) , but I have not 

 seen it in nature. 



I may add, that I noticed among Herr von Nolcten's types, two 

 specimens of a species which I would be inclined to describe as new.

Revision of the genus Eupelix. 



My last paper with the above title will be found at p. 276, vol. 

 xii, of this magazine. Since that time, I have desisted from describing 

 other British genera or species of this Order because I believed that 

 the few remaining ones, which I had not noticed in my previous papers, 

 were so well-known and understood by every student as to require no 

 notice from me. Nor would I now have begun afresh, had I not had

 to write, has the peculiarity of having, so far as I am aware, only four 

 species in the whole world, and singularly these are all European, 

 except JJ. marginata, Eieb. The similarity of the species has given
