and subterminal line was developed into a browa band ; the transverse basal, median 

 and subterminal lines on tlie fore-vFings, and the median and subterminal lines on 

 the hind-wings, being strongly marked in dark brown. It was taken by Mr. J. 

 Mason at Clevedon in March, 1893. Mr. Tutt also exhibited the cocoons, pupa- 

 skin, and aberrations of the imago of Zygcena exulans. The cocoons were spun 

 upon one another, five in a cluster, and Mr. Tutt stated that the species was 

 exceedingly abundant in the pupal and imaginal stages during the first week of 

 August on tlie mountain slopes above Le Lautaret, in the Dauphine Alps, at from 

 7,0U0 to 9,000 feet elevation. The pupa-skin was very similar to tliose of other 

 Zygsenids. The imagines exhibited were all aberrations, and consisted of females of 

 the ab. flavilinea, with bright yellow nervures ; a large male and several females of 

 the ab. striata, with the red spots more or less confluent and developed into streaks ; 

 also, an unique female aberration in which tlae wing, from the base to far beyond 

 the centre was entirely crimson. Dr. Sharp, a specimen of a Lepidopterous 

 insect that had been alluded to in " The Entomologist's Monthly Magazine," Sept., 

 1896, p. 201. It was a caterpillar which liad received the eggs of a parasite on the 

 anterior part of the body, the abdomen, nevertheless, went on to the pupal meta- 

 morphosis, while the head and thorax remained attached to it in the caterpillar 

 stage. He also called attention to some peculiarities in the pupa of Plusia moneta, 

 pointed out to him by Mr. Fleet ; in this species the pigmentation varies greatly in 

 extent, and is sometimes entirely absent. Mr. Blandford called attention to the 

 recent discoveries relating to the Tsetse fly, made by Surgeon-Major Bruce in Zulu- 

 land, which proved that this insect affected animals by infecting them with a 

 parasitic Protozoon. The parasite was communicated from wild animals to domestic 

 animals, and was probably more widely distributed than was generally believed, it or 

 a closely allied form having been found in India and England in sewer rats. He 

 said that Surgeon-Major Bruce had proved that the Tsetse fly was pupiparous, which 

 was of importance as affecting the classification of the Diptera,. Dr. Sharp said 

 that in his opinion the Tsetse fly would cease to be troublesome with the advance of 

 civilization. Mr. C. G. Barrett exhibited the pupa-skin, cocoon and eggs of Hesperia 

 comma, L., found on chalk hills near Reading by Mr. A. H. Hamm. He also exhibited 

 and remarked on a series of both forms of Tephrosia crepuscularia and T. liundularia, 

 showing an unbroken line of variation from brown to white and also to grey and 

 black. In addition, he showed sevei'al second-brood specimens of both forms 

 obtained in the past summer by Mrs. Bazett of Reading. Mr. Tutt and Mr. Fenn 

 made some remarks on the specimens exhibited. Mr. Tutt read a paper, entitled, 

 "On the specific identity of Cmnonym'pha Ipkis and C. Satyrion," and exhibited a 

 long series of specimens. The Rev. T. A. Marshall communicated a paper, entitled, 

 "A Monograph of British BraconidcB. Part VII." Mr. T. D. A. Cockerell 

 communicated a paper, entitled, " New Hymenoptera from the Mesilla Valley, New 

 Mexico." Mr. E. Meyrick contributed a paper, entitled, " On Lepidoptera from the 

 Malay Archipelago." Dr. Sharp read a paper by Mr. G. D. Haviland and himself, 

 entitled, "Termites in Captivity in England."— H. Goss AND W. W. Fowler,
