190 SELECTED NOTES FROM 



Crustacese, for when so mounted they are susceptible to polarised 

 light, or the paraboloid may be used. Few crustaceans, when 

 alive, form more beautiful objects, whether viewed transparent, 

 polarised, or with spot-lens.

Caligus rupens is a common parasite on sea-fish, and may 

 often be found on salmon, etc., at the fishmongers. They are 

 popularly known as Sea-Lice. The females are furnished with two 

 long strings of ova, which give them a very peculiar appearance.

Acari from Chaffinch. — This mite very much resembles one 

 found in a cheap quality of raw sugar, and is commonly known as 

 the sugar-mite. E. Lovett. 



By staining this mite, the curious pads which serve as feet 

 would be shown very plainly ; otherwise, they are almost invisible.

Eggs of Vapourer-Moth, 0. Antiqua, are attached to the 

 cocoon, on which the wingless female, after crawling out of the 

 pupa-case and receiving the male, which is attracted by a sense 

 peculiar to a few species, such as Carpini, Qtierciis, etc., deposits 

 her eggs, and then dies. E. Lovett. 



May I venture to differ from Mr. Lovett on what he says about 

 the Female of the Vapourer-Moth dying after depositing her eggs ? 

 Two or three years ago, one of these creatures made her nest in a 

 chink on the outside of one of my windows, and I watched her 

 with interest. She laid several eggs, but all had been hatched, 

 and I had caught several full-grown vapourers to put into my 

 cabinet, whilst she was still alive. I killed her, however, because 

 I wanted her to grace my cabinet also, and there she is now.

Exuvia of Pupa of Circopides (Frog-Hopper).— A great 

 quantity of these were found on the underside of oak-leaves in 

 Goodnestone Park, in August; sometimes as many as six or seven 

 were found on one leaf. They are attached by a thread or two, 

 probably to assist the insect in extricating itself I have searched 

 the oaks at Wood Green without finding a single specimen.
