odour for the attraction of the J , but I do not think anyone has 

 recorded smelhng this odour. The case in question, however, is a 

 ^ odour to attract the $ , which I think probably exists in hum id i, as 

 in hectus. This is a rare case, so far as records go. Most odours that 

 can be detected are, either in both sexes for benefit from enemies, or 

 in $ , not to attract ? , but to charm her after he has been 

 attracted. Tliis is much the most common in butterflies. From 

 what I have seen of courtship in butterflies, I beUeve the ? attracts 

 the J by sight (as well as scent) and then has to be "charmed" by 

 the , both by display of colour, and by a special scent — varying, of 

 course, in different species. — T. A. Chapman, Firbank, Hereford. 



Larv.e Destroyed by Mice. — A few days ago I had about 130 

 larvae of Bhirtavia in a large cage, and now they are reduced to 6, 

 eaten by nuce. They had made a hole through the gauze or leno 

 which covered a part of the cage. Recently they have eaten many 

 valuable imagines of mine, but I did not suspect them of eating larvae.

Coleoptera.— Notes. 



SiLPHA LiTTORALis. — On Saturday, May 21st, I took a very nice 

 specimen of this beetle under a dead hedgehog at Mottisfont, near 

 Romsey. — R. Beck, Burnside, Southampton. 



Geotrupes pyren.eus. — I captured a single specimen of this dung 

 beetle flying in the hot sunshine on May 26th. I have not seen it 

 since August, 1890, when I took one at Swanage. — Id. 



Cicindela sylvatica. —Being in the neighbourhood of Aldershot 

 to-day (May 26th) I again paid a visit to North Camp in search of 

 this beetle and was rewarded by capturing twelve in excellent 

 condition. This time I took a sweep net with me and found it easier 

 to transfer them from it to the killing bottle than from the butterfly 

 net with which I took the specimens in September, iSgo. I again 

 noticed that this insect confined itself to an area of about fifty square 

 yards and although 1 walked a quarter of a mile from all four sides I 

 did not meet with a single specimen. — Id. 



Captures at West Wickham. — On Saturday, June nth, I paid 

 a visit to Mr. Chaney, and durin-^ the afternoon went with him to 

 West Wickham. Insects were not common, but I managed to net. 

 several Aphthoiia veiiustula, HL-FiineopJiaga luercnvuilis, Straugalia 

 melanum, &c. Also, by beating birch, hazel, and oak, Rhyncliites 

 inegncephnlus, R. ikuuls, Polydrosns iindiitiis, Cryptoccpludns fiilcrntus^ 8cc.

PoLTDROSUS micans. -On June nth, I was fortunate in getting 

 four specimens of this good weevil at West Wickham. Three were
