are introduced in language of the author's own, having a special value 

 quite apart from the rest of the work. Nor is this all ; for the characters 

 are drawn not simply from the complete stage of the insects, but from the 

 larva and pupa as well, and these same stages are introduced in the 

 generic descriptions. It is unfortunate that he has not included also the 

 egg. The work is illustrated so far by ten octavo plates, one of which is 

 devoted to the structure of the wings, the head and legs of the imago ; two 

 to the early stages of a few species, and the remainder to excellent chromo- 

 lithographs of the perfect insects. The figures of the early stages are an in- 

 teresting, though somewhat scanty, addition to our knowledge, the most 

 important of which is found in the larva and pupa of D'Urbania, a curious 

 genus of Lycaeninae, in which the pupa, as well as the larva, is covered 

 with long fascicles of hairs, as long as the width of the body. Mr. Trimen 

 has been aided by collectors and naturalists throughout Southern Africa 

 to a very great extent, so much so, indeed, that he has added to his title 

 page the name of one of them, Col. Bowker, as joint author with himself ; 

 and the help he has received in this respect may be indicated in part by 

 the considerable number of species which have been added to the list of 

 South African butterflies since the publication of his first work, a total of 

 3S0 against 197. An excellent coloured map of Southern Africa, south of 

 the tropic of Capricorn, is prefixed to the first volume. We hope the third 

 volume, completing the work, will soon be issued.

REMEDY FOR ROSE-APHIS. 



Dear Sir : Experiments with a weak solution of Creolin upon Rose 

 Aphides and leaf-tying larvae ( Tortrix) proved quite successful without 

 any apparent injury to the plants. Rose bushes syringed with Creolin 

 solution remained for some time after free from insects of any kind fo far 

 as I could observe. More continued use of Creolin must be made to 

 speak with certainty, but it seems to me likely that in this disinfectant we 

 may have a valuable help for garden or greenhouse.
