 The great fact of practical imijortance is that it is useless to protect the hacks 

 of cattle against the flies, since nothing will induce the insects to oviposit 

 there, not even when the legs are artificially covered up.

Mention was made in the preceding summary of Dr. Hadwen's observations 

 on Hypoderni'.i. The present paper deals with some points connected with 

 another genus of Oestridae. The larvae of the various species of Cuterehra are 

 found in the bodies of rodents^squirrels, rabbits, field-mice, &c. In some cases 

 the fall-grown larva seems astonishingly large in proportion to its unfortunate 

 host. These larvae are situated under the skin (rather after the manner of 

 f ull-gi'own Hypoderma) of various parts of the body. C. fontinella is a parasite 

 of Lepus artemisia ("Cottontail"). Its eggs closely resemble those of the 

 horse-bot, Gastrophilus equi, having a groove on one side for attachment to a 

 hair of the host. These are probably the first eggs of the genus Cuterehra to 

 be described.

Prof. Poulton exhibited a female Asilid, Promachus sp., captured with its 

 prey, a male Delias descombesi Boisd., August 18th, 1914, at Takdah (5,000 ft.), 

 Sikkim, by Major T. D. Broughton, E.E. Prof. Poulton, the specimen of the 

 African Hesperid butterfly, Ploetzia ceryviica Hew., referred to in the following 

 note written December 26th, 1914, by Dr. Gr. D. H. Carpenter, from Kakindu, 

 about 30 miles W. of the Victoria Nyanza and 500 ft. above it. " I send you a 

 skipi^er of much interest. It came to light one night (December 23rd) about 

 9 p.m., and behaved much like a moth. The feature of interest is the large 

 white pa.tch on the antenna, which was extremely conspicuous and really glistened 

 in the light almost as if it were phosphorescent." Prof. Poulton said that 

 the species was usually diurnal. Commander J. J. Walker, on behalf of 

 Mr. F. C. Woodforde, bred specimens of Zonosoma pendularia L. var. subroseata 

 Woodforde, and var. suhochreata Woodforde, with the type-form of the species 

 for comparison. Mr. W. C. Crawley, di'awings of various species of ants, of two 

 kinds of organs in the funiculi of antennae. They are often, if not always, in 

 the living insects, filled with air, and inaj'- possibly be connected with the 

 sense of hearing; also several drawings of the genital armatures of ^ 

 ants. Mr. H. Willoughby Ellis, two teratological specimens of Coleoptera, 

 viz., a male specimen of Carabus nemoralis Miill., and a specimen of the dark 

 variety of Campylus linearis L. Mr. Champion, on behalf of Mr. W. West of
