THE YOUNG NATURALIST. 



[December 



Saturday was showery all day. In the evening I caught a very 

 good Geometra papilionaria as it came slowly flying out of a wood. 



On Monday, 22nd July I left Loch Ridon and many friends behind 

 me, with much regret, but with the hope that I may return some other 

 year to further investigate the insects of this beautiful countryside.

ENTOMOLOGICAL SOCIETY OF LONDON. 



November 6. 1889— Prof. J. O. Westwood, M.A., F.L.S., Hon. Life President 

 in the chair. 



Mr. Richard S. Standen, of Framlingham Earl Hall, Norwich, was elected a 

 Fellow ; and the Rev. C. F. Thornewill, M.A., was admitted into the Society. 



Mr. J. W. Douglas sent for exhibition specimens of Anthocoris visci, Dougl., a new 

 species taken from the mistletoe, at Hereford, in the end of September last by Dr. 

 T. A. Chapman ; also specimens of Psylla visci, Curtis, taken by Dr. Chapman from 

 the mistletoe at the same time and place. 



Mr. R. M'Lachlan exhibited coloured drawings of a specimen of Zygcena filipen- 

 dala, in which the left posterior leg is replaced by a fully-developed wing, similar to 

 an ordinary hind wing, and with the neuration almost precisely the same, but less 

 densely clothed with scales. The specimen was described by Mr. N. M. Richardson 

 in the Ent. Mo. Mag. for June, 1889, and the drawing was executed by Mrs. Richard- 

 son. Mr. M'Lachlan also exhibited a female specimen of the common earwig Forfi- 

 cula auricular ia, with a parisitic Gordius emerging from between the metathorax and 

 and abdomen. He said that it had been placed in his hands by Mr. A. Farn, by 

 whom it was taken, and that other instances of similar parasitism by Gordius on 

 earwigs had been recorded. 



Mr. W. F. Kirby exhibited a gynandromorphous specimen of Lycana icarus, 

 having the characters rf a male in the right wings and the characters of a female in 

 the left wings, caught by Mr. T. Brown at Keyingham, Yorkshire, on the 22nd of 

 June last ; also a specimen of a avriety of Crabro interruptus, De Geer, found by Mr. 

 F. Woodbridge in a hole in a log at Uxbridge. 



Mr. W. L. Distant exhibited a male and female specimen of a species belonging 

 to a new genus of Discocephalina, from Guatemala, in which the sexes were totally 

 dissimilar, the female having abbreviated membranes, and being altogether larger 

 than the male. 



Dr. D. Sharp stated that he observed that in the Ipsince division of Nitidulidas 

 there was present a stridulating organ in a position in which he had not noticed it in 

 any other Coleoptera — viz., on the summit of the back of the head. He had found it 

 to exist not only in the species of Ips and Cryptarcha, but also in other genera of the 

 subfamily; on the other hand, he could not find any trace of its existence, except in 

 members of the Ipsina. He exhibited specimens of Ips and Crptarcha, mounted to 

 show the organ. Dr. Sharp also exhibited a box of Rhynchota, chiefly Pentatomida, in
