female, used its legs for propelling itself through the water. Aberra- 

 tion OF Tephrosia bistortata. — Mr. Tutt exhibited a beautiful aber- 

 ration of Tephrosia bistortata (r rcjmscular ia) , in which the ochreous 

 ground-colour was much intensified, and the transverse shade between 

 the median and subterminal line was developed into a brown band ; 

 the transverse basal, median and subterminal 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. Cocoons and aberrations of Zyg^na 

 ExuLANs. — Mr. Tutt also exhibited the cocoons, pupal-skin and aber- 

 rations of the imago of Zi/i/acna cculana. 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 7,000 to 9,000 feet elevation. The 

 pupa-skin was very similar to those of other Zygtenids. The ima- 

 gines exhibited were all aberrations, and consisted of females of the 

 ab. fiarilinra, 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 

 the wing, from the base to far beyond the centre, was entirely crimson. 

 A STRANGE EFFECT OF Pakasitism. — Dr. Sharp exhibited a specimen 

 of a lepidopterous insect that had been alluded to in The Kntoiiiolo<jisVs 

 Monthli/ Magazine, Sept., 1896, p. 201. It was a caterpillar which, having 

 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. 

 Pigmentation of pupa of Plusia moneta. — 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. The Tsetse fly. — Mr. Blandford 

 called attention to the recent discoveries relating to the Tsetse fly, made 

 by Surgeon-Major Druce in Zululand, which proved that this insect 

 aflected animals by injecting them with a parasitic Protozoon. The 

 disease had spread from wild animals to domestic animals, and the 

 parasite was more widely distributed than was generally believed, 

 and had been found in India and England in sewer rats. He said 

 that Surgeon-Major Bruce had proved that the Tsetse fly was pupi- 

 parous, which was of importance as aftecting the classification of the 

 Diptera. Dr. Sharp said that, in his opinion, the Tsetse fly would 

 cease to be troublesome with the advance of civilisation. Pupa-skin, 

 COCOON AND eggs OF Pamphila COMMA. — Mr. C. G. Barrett exhibited 

 the pupa-skin, cocoon and eggs of Pamphila (■o)iiiiia, found on chalk 

 hills, near Reading, by Mr. A. H. Hamm. Tephrosia bistortata 

 (crepuscularia) and T. crepuscularia (biundularia). — Mr. Barrett 

 also exhibited, and remarked on a series of both forms of Tephrosia 

 crepuscularia and T. bimuhdaria, showing an unbroken line of variation 

 from brown to white, and also to grey and black. In addition, he 

 showed several second-brood specimens obtained in the past summer 

 by Mrs. Bazett, of Reading. Messrs. Tutt, Tunaley and Fenn made 

 some remarks on the specimens exhibited, and gave it as their opinion 

 that the two insects were abundantly distinct. Papers. — Mr. Tutt 

 read a paper entitled, " On the specific identity of Coouini/injjha iphis 

 and C. satyr ion," and exhibited a long series of specimens. The Rev.
