Extracts from the Proceedings of the Entomological Society, 

 November 20, 1871, <o January 1, 1872. 



Variety of Bomhyx Trifolii. — Mr. Bond exhibited a series 

 of small pale examples of Bombyx Trifolii. He had made a 

 similar exhibition a year or two since, and Mr. Milford, their 

 discoverer, furnished the following information, tending to 

 prove that they formed, at any rate, a distinct local form. 

 The locality is Romney Marsh, Kent, and the larvae were 

 first found by Mr. Mitford in May, 1866, feeding in the tufts 

 of a very wiry grass growing in the shingle above high-water 

 mark; they were again found and bred in May, 1867: in 

 August, 1868, two dead moths, exactly similar, were observed 

 in the same locality ; and in August, 1871, eighteen examples 

 were bred. While hunting for these larvae, Mr. Mitford's son 

 found smaller caterpillars, which produced Lithosia caniola, 

 thus showing an entirely new locality for this species. 



Variety of Bomhyx castretisis. — Mr. Bond further exhibited 

 two remarkable varieties of Bombyx castrensis. One of them, 

 a female, had the left-hand wings shaped like those of the 

 male, though the insect otherwise showed no tendency to be 

 gynandromorphous; the other, also a female, had the right- 

 hand under wing marked and banded as in the upper wing. 



Variety of Tryphaena orhona. — Mr. Stainton exhibited, on 

 behalf of Mr. D'Orville, a singular variety of Tryphaena 

 orbona. 



Variety of Argynnis Aglaia. — Mr. S. Stevens exhibited, on 

 behalf of Mr. Shearwood, an extraordinarily dark variety of 

 Argynnis Aglaia, captured near Teignmouth. 



Malformations of British Lepidoptera. — Mr. Bond exhi- 

 bited, on behalf of Mr. Doubleday, varieties or malformalions 

 of British Lepidoptera, as follows:— (1) Melitaea Artemis, 

 with the antennae scarcely more than half the usual length ; 

 (2) Pieris Rapae, female, with only a faint trace of the second 

 spot on the upper wing; (3) Anchocelis lunosa, male, taken 

 at sugar, the right-hand upper wing much broader than the
