THE YOUNG NATURALIST. 



It is of course necessary to keep each box stocked with some preservation 

 to destroy mites, and nothing is more effective than a particle of napthaline, 

 about the size of a hazel nut, wrapped in a piece of muslin and securely 

 pinned in the corner of the box. If this is attended to, the insects will be 

 preserved for years, and should the collector, from pressure of business or 

 other causes, be obliged to put aside his entomological pursuits for a time, 

 when he returns to it he will find his previous captures in good condition, so 

 that he will again be induced to take up his favourite study with pleasure and 

 enthusiasm.

REPORTS OF SOCIETIES. 



ENTOMOLOGICAL SOCIETY OF LONDON. 



June 1, 1887. — Dr. David Sha.;rp, E.Z.S., President, in the chair. 



Mr. Philip Crowley exhibited the following specimens of Diurni, from the 

 Kareen Hills, Burmah :—Papilio Zaleucus, P. Adamsoni, Papilio f sp. (male 

 and female), and Nymphalis Nicholii. 



Mr. T. E,. Billups exhibited several specimens of an ant found at Kew, 

 frequenting a species of palm from Tropical Australia, and which had been 

 determined as Tapinoma melanocephalum ; also living specimens of Carabus 

 auratus, from the Borough Market, and of a species of Blaps from Northern 

 Africa. 



Mr. Waterhouse exhibited a specimen of a Brazilian Locust, Conocephalus 

 sp., which he had for some time preserved alive, and which had only died that 

 same morning. He called attention to the change of colour which he had 

 observed in the eyes of this insect ; in a bright light they were dirty white or 

 horn-coloured, with a black dot in the middle ; but at night, or if the insec 

 were confined in a dark box, they became altogether black ; shortly afte 

 death, also, the eyes became black. Mr. M'Lachlan observed that he ha 

 noticed a darker spot in the centre of the eye in certain Ephemeridse, and i 

 other Neuroptera. The discussion was continued by Dr. Sharp and others 

 but no one seemed to be able to account for the alteration in question. 



Lord Walsingham exhibited specimens of Cater emna terebrella, Lk., a species 

 lately taken in Britain, which he had caught in Norfolk, and bred from fir- 

 cones gathered in the same locality. 



Mr. Meyrick read two papers, "On Pyralidina from Australia and the 

 South Pacific " and " Descriptions of some exotic Micro-Lepidoptera." In 

 these papers about sixty new species were described. A discussion ensued
