“ Plebeius argus.—Many of this species very deficient were 
taken by me at St. Martin Vésubie. 
‘“ Lycaenopsis argiolus.—I only took three specimens at la 
Sainte Baume and one female at St. Martin, and all of these are 
deficient. 
“Now in what stage does this curious and_ interesting 
phenomenon take place? Something, I imagine, must occur 
at a critical time in the life of the larva. I am disposed to 
think towards the end of that stage, for it does not affect the 
size of the insects at all; it therefore cannot be malnutrition 
in the ordinary sense, and it seems to me that it is likely to be 
at some brief critical period after the last ecdysis and before 
pupation.” 
Mr. G. Tatzsor exhibited specimens of Huploea from the
