Dr. D. Sharp stated he had observed that in the Ipsince division of Niti- 

 dulidce 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 other trace 

 of its existence, except in members of the Ipsince. Dr. Sharp also exhibited a box 

 of Rhynchota, chiefly Pentatomidce, in which the specimens were prepared so as to 

 display the peculiarities of the terminal segment of the male sex. 



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

 of Polia xanthomista, var. nigrocincta, from the Isle of Man, and Cidaria reticulata 

 and JEmmelesia tceniata 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. Westwood made some remarks on the subject. 



Mr. H. J. Elwes exhibited a number of insects of various Orders, part of the 

 collection formed by the late Otto Moller, of Darjeeling. 



Mons. A. Wailly exhibited the cocoon of an unknown species of Anthercea from 

 Assam ; also a number of cocoons and imagos of Anophe venata from Acugua, near 

 the Gold Coast, West Africa; specimens of Lasiocampa otus, a South European 

 species, which was said to have been utilized by the Romans in the manufacture of 

 silk ; also a quantity of nests containing the eggs of Epeira madagascariensis, a 

 silk-producing spider from Madagascar, locally known by the name of " Halabe." 



Mr. H. Gross read a communication received from Mr. S. H. Scudder, of Cam- 

 bridge, Mass., U.S.A., on the subject of his recent discoveries of some thousands of 

 fossil insects, chiefly Coleoptera, in Florissant, Western Colorado, and Wyoming. 

 Prof. Westwood remarked on the extreme rarity of fossil Lepidoptera, and called 

 attention to a recent paper by Mr. A. G. Butler, in the Proc. Zool. Soc, 1889, in 

 which the author described a new genus of fossil moths belonging to the Geometrid 

 family Euschemidce, from a specimen obtained by Mr. A'Court Smith, at Gurnet 

 Bay, Isle of Wight. 



Mr. F. P. Pascoe, read a paper, entitled " Additional Notes on the genus 

 Hilapus," and exhibited a number of new species belonging to that genus. 



The Rev. Dr. Walker read a paper, entitled "Notes on the Entomology of 

 Iceland." Mr. Roland Trimen asked if any butterflies had been found. Dr. Walker 

 said that neither he nor Mr. P. B. Mason had seen any during their recent visit to 

 Iceland, nor were any species given in Dr. Staudinger's list. In reply to a question 

 by Mr. G. C. Champion, Mr. Mason said that during his recent visit to Iceland he 

 had collected nearly one hundred species of insects, including about twenty Coleoptera. 

 He added that several of the species had not been recorded either by Dr. Staudinger 

 or Dr. Walker. Mr. Elwes enquired if Mr. J. J. Walker, with his great experience 

 as a collector in all parts of the world, was aware of any land except Iceland, outside 

 the Arctic Circle, from which no butterflies had been recorded. Mr. J. J. Walker 

 replied that the only place in the world which he had visited in which butterflies 

 were entirely absent was Pitcairn Island. — H. Goss, Hon. Secretary.
