FEBRUARY 24th, 1910. 



Mr. Alfred Sich, F.E.S., Vice-President, in the Chair. 



Dr. G. S. Robertson, of Duiwich, was elected a member. 



Dr. Chapman exhibited a bred specimen of Calloplirys 

 avis, and pointed out that it differed from the nearly related 

 C. rubi in being somewhat larger and in lacking the white line 

 on the face and the silvery lines around the eyes, as well as 

 in its life-history (see " Trans. Ent. Soc. Lond.," 1910, 

 pp. 85-106, pis. 14-43). 



Mr. Barnett exhibited a long series oi Hybernia aurantiaria, 

 taken in West Wickham Wood, where it was very abundant 

 in November, igog. 



Captain Cardew exhibited several gynandromorphs, in- 

 cluding Dryas paphia, in which the right side and two-thirds 

 of the left hind-wing were female, the remainder of the left 

 side male, a peculiar feature being the fact that the line of 

 demarcation between the sexes lies in the space between two 

 nervures. The specimen was taken by him in the New 

 Forest in i8g3, and was exhibited by Mr. C. G. Barrett at 

 the Entomological Society of London in the same year 

 (" Entom.," xxvi, p. 329). Amorpha populi, exactly divided, 

 the left side, including wings, legs, and antenna, being male, 

 and the corresponding parts on the right female. Bred 

 from a Dover larva, igog (" Entom.," xlii). A gratis piita, 

 exactly divided, the left side male, right side female ; antennae 

 corresponding (" Entom.," xli, p. 229). 



Mr. A. Russell exhibited a strikingly aberrant form of 

 Pulyominatus icarits from Reigate, where it was captured on 

 May 22nd, igog. The underside of the right sidewin$:rs had 

 the submarginal spots elongated to broad striae, while the 

 left side had normal markings. 



Mr. Sperring exhibited Agrotis agathina from Chislehurst, 

 and also a very smoky bred specimen of Arctia villica. 



Mr. R. Adkin exhibited a series of Peronia periuutana, 

 reared from Sussex larvas. He said that on a former occa- 

 sion he had exhibited a specimen of this species reared from 

 a larva taken on the coast near Beachy Head, where for 

 many years the species had been known to occur sparingly
