this species I actually threw away three or four cocoons of 

 the first lot, thinking that ichneunionid parasites had emerged 

 from the larvae. I have bred hundreds of the insects, of 

 which there are two forms of imago, one black-and-white, 

 the other black-and-buff. The larva is black-and-white, 

 slightly hairy, as may lie seen in blown specimens sent by me 

 to the British Museum and Tring Museum. It feeds on a low 

 plant, but always climbs up on to a fence, wall or trunk of a 

 tree to make its cocoon. The larva is protected and distaste- 

 ful to birds. Mantis, etc. The cocoon is formed of a substance 

 very much like jelly, which, as long as the pupa is alive re- 

 mains soft; if, however, the pupa dies the substance becomes 

 dry and shrink- also. The pupae will live if the substance 

 that forms the cocoon 18 taken off. The colour of the pupa is 

 brown. The cocoon-lik' bodies vary in tint, but are 

 generally yellow, although 1 have had them white like verj 

 small pieces of boiled rice. The duration of the pupal state is 

 very short, nol more than a week. The larva is attacked by 

 an ichneumon of apparently the same species as that which is

Genus Marmara. — Prof. Poultoh said that lie had been 

 shown by Mi. d. H. Durrant the spherical bodies scattered 

 over the cocoon of the Tineid moth Marmara salictella, 



Clemens, and had no doubt that they were secreted by the 

 larva and passed by the anus as in I)> ih imni. It. would be 

 interesting to observe whether any of the common parasites 

 of Tineids construct cocoons to which the spheres bear any 

 marked resemblance. At first sight the appearance suggested 

 i- rather that of a mass of spiders' eggs such as are often seen 

 in chinks of bark. Here, too, it is important to ascertain by
