240 THE ENTOMOLOGIST. 



The Thrips of the Fuchsia. — For some time past the 

 leaves of our fuchsias have been attacked by two sorts of 

 parasites : one of these belongs to the division of the Orthopters 

 Pseudo-neuropters ; to the genus Heliotlirips ; to the species 

 Heliothrips adonidum, Haliday, or H. heinori'oidalis, Bouche. 

 This thrips lives on the lower sides of the leaves, of which it 

 devours the outer surface ; it is very destructive, and very difficult 

 to destroy. Do your readers know anything about this insect ? 

 Have there been any publications on this subject, and in what 

 papers? — E. Lefevre ; 36, Place des Marches, Eheims, France, 

 August 9, 1882. 



[We are not aware of anything authentic that has been written 

 on this subject. Perhaps some of our readers can give information. 

 Mr. Pergande's note (Entom. xv. 94) may interest our corre- 

 spondent. — Ed.] 



Napthaline. — The note on the use of napthaline for the 

 protection of insect collections, in )^our July number (Entom. xv. 

 105), attracted my attention. I beg leave to state that I have used 

 napthaline for over a year in my collections of eggs, mounted 

 birds, bird skins, nests, and a general collection of insects. I have 

 always had uniform success. I procure it in lumps, of a pale pink 

 colour. I have never tried Mr. C. A. Blake's cones, for the reason 

 that I am satisfied to let well enough alone. I hope to hear 

 more on this subject. — Erastus Corning, jun. ; 22, Elk Street, 

 Albany, N.Y., U.S.A., July 30, 1882. 



Naphthaline versus Camphor. — Naphthaline is largely, I may 

 say generally, used by foreign collectors. The Germans seem to 

 have a very strong prejudice against camphor, as injurious to the 

 specimens and also to the health of those who frequently breathe 

 the fumes from their cases. I have for some years used naphtha- 

 line in the store-boxes which contain mj'^ collections, and have 

 now entirely abandoned the use of camphor. I find the former 

 most efficacious as a preventative. It will not cure an infected 

 case : for this and quarantine purposes I use a few. drops of 

 bisulphide of carbon on cotton-wool, repeated once or twice at a 

 few weeks' interval of time. This is fatal to all insect-life, but 

 must be used with the greatest caution, as the effects of the fumes 

 upon human life are most injurious. To prevent mould a small 

 piece of cotton-wool on the head of a long pin, dipped in glacial 

 carbolic acid and placed in the case, is a perfect remedy. — [Rev.]
