ENTOMOLoaicAL SociETY OF LoNDON. — November 6th, 1889. — Prof- 

 J. 0. Westwood, M.A., F.L.S., Hon. Life-President, in the chair. Mr- 

 Kichard 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 misletoe, at Hereford, in the end 

 of September last, by Dr. T. A. Chapman ; also specimens of Psylla visci, 

 Curtis, taken by Dr. Chapman from misletoe, at the same time and place. 

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

 filipendulcE, 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. Richardson. Mr. M'Lachlan 

 also exhibited a female specimen of the common earwig, Forficula auricu- 

 laria, with a parasitic Gordius emerging from between the metathorax and 

 abdomen. He said that it had been placed in his hands by Mr. A. B. 

 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 Lyccena icarus, having the characters of 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 variety 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 Discocejihaliim, 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 had observed that in 

 the Ipsin(B division of NitiduUdcB 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 sub- 

 family ; 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 

 Cryptarcha, mounted to show the organ. Dr. Sharp also exhibited a box 

 of Rhynchota, chiefly Pentatomida, in which the specimens were prepared 

 so as to display the peculiarities of the terminal segment in the male sex. 

 Mr. R. Adkin exhibited, on behalf of Mr. H. Murray, of Carnforth, a fine 

 series of Folia xanthomista, var. nigrocincta, from the Isle of Man, and 

 Cidaria reticidata and Emmelesia taniata from the Lake District. Mr. 

 W. White exhibited a living larva of Zeuzera cesculi, and called attention 

 to the chitinous scutum or thoracic segments with several rows of minute 

 serrations, which evidently assist progression. He stated that the larva 

 exudes from its mouth, when irritated, a colourless fluid, which he had 

 tested with litmus-paper and found to be strongly alkaline. Prof. West- 

 wood made some remarks on the subject. Capt. H. J. Elwes exhibited a 

 number of insects of various orders, part of the collection formed by the 

 late Otto M oiler, of Darjeeling. Mons. A. Wailly exhibited the cocoon of 

 an unknown species of Antheraa from Assam ; also a number of cocoons 

 and imagos of Anophe venata from Acugua, near the Gold Coast, West
