440 THE ZOOLOGIST. 



transverse shade between the median and subterminal line was developed 

 into a brown band ; the transverse basal, median and snbterminal lines on 

 the fore wings, 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, pupal-skin, 

 and aberrations of the imago of Zygana exalans. 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 the mountain slopes above Le Lautaret, in the Dauphine 

 Alps, at from 7000 to 9000 feet elevation. 



Dr. Sharp exhibited a lepidopterous insect that had been alluded to in 

 the ' Entomologist's Monthly Magazine,' Sept. 1896, p. 201. It was a 

 caterpillar which had received the eggs of a parasite on the anterior part of 

 the body ; the abdomen, nevertheless, went on to the pupal metamorphosis, 

 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 Zululand, 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. 

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

 was of importance as affecting the classification of the Diptera. 



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

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

 also exhibited a series of both forms of Tephrosia crepuscularia and I 1 , biundu- 

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

 to grey and black. In addition he showed several second-brood specimens 

 of both forms obtained in the past summer by Mrs. Bazett, of Reading. 



Mr. Tutt read a paper "On the specific identity of Ccenonympha iphis 

 and C. satyrion," and exhibited a long series of specimens. 



The Rev. T. A. Marshall communicated a paper entitled "A Monograph 

 of British Braconidse. Part VII." 



Mr. T. D. A. Cockerell communicated a paper entitled " New Hymen- 

 optera from the Mesilla Valley, New Mexico." 



Mr. E, Meyrick contributed a paper " 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,
