thetis, females, from Folkestone, taken in igio, and a very 

 interesting^ example which he supposed to be a natural 

 h\-brid between A. coridon, male, and Polyommatus icarus, 

 female, or A. thetis, male, and P. icants, female (see"Ent.," 

 vol. xliv, p. 4, tig. in text). 



He also showed a fine male Grapta (Polygonia) c-albiun, 

 with the whole of the ground colour yellow, one of eleven 

 specimens he and others had bred from the same batch of 

 ova. The parents were quite normal var. hiitchinsoni, and 

 the grandparents also quite typical. His own larvse were 

 fed on elm, and sleeved out on a growing tree. The first 

 batch of pupas were cut off the tree, and produced two yellow 

 varieties. The remaining larvae were fed up in a hot-house, 

 as they were so late, and food was getting scarce. These 

 last produced four yellow examples. The undersides of all 

 the yellow varieties were a trifle darker than those of the 

 typical forms bred from the same brood. 



Mr. H\'. J. Turner exhibited a teratological specimen of 

 Danais limniace. in which the left fore-wing was diminished 

 in size, with a large indentation in the hind margin, reaching 

 nearly half the length of the wing, and partly ciliated. 



Mr. Buckstone exhibited a box of teratological specimens, 

 including Epionc advcnaria, Orgyia antiqita, Cupido minima, 

 Nyssia Jiispidaria, Hadcna pisi, and Anchocelis pistacina, with 

 left hind-wing dwarfed or missing ; Vanessa atalanta, with all 

 the wings abnormally broad ; and Panagra petraria and 

 Agrotis tritici, with a sinus in the wing-margin fully fringed.
