This comraunication is in continuation of my previous 

 Notes on Puj)^. (Trans. Ent. Soc. Lond., 1893-94). It 

 refers especially to a character of certain pupte, that 

 occurs and appears to show a relationship in a large group 

 of TM?-eMi«, and incidentally it deals with the plume moths, 

 and some forms that have, or are supposed to have, 

 affinities with them. 



I may, in the first place, correct two errors in my 

 previous papers ; the most important of these, or at any 

 rate the one for which I feel I am most to blame, is as 

 to the free segments in the Limacodidfe. In the Lima- 

 codids, not only are segments (abdominal) 3, 4, 5, 6, free, 

 but also 1 and 2, in the sense in which I now understand 

 the word, that is, they are not soldered to the wings and 

 appendages, and appear to be capable of independent 

 movement on each other. It is extremely probable that 

 the insect, however, never does so move them, and rarely, 

 if ever, indeed, moves the others, being packed closely in 

 and well pi'otected by its cocoon. In explanation of my 

 error, I may say that these two segments are so closel}' 

 applied to the appendages, that when one separates them 

 by ti'action in the living pupa one fears to tear the 

 delicate pupa to pieces, and suspects that the separation 

 is made by breaking down actual slight soldering — an 

 occurrence which I have pointed out takes place very 

 readily in those pup^ in which the process of fusion of 

 the parts is in its early stages, the greater part, that is, 

 of the lower " Incompletsi " in fact, such as Limacodids, 

 Nepticulids, Adelids, etc. Then in the empty case all 

 segments and appendages are so freely separate that this 

 state of the pupa throws no light on the extent of solder- 

 ing in the living pupa. The error is only of importance
