starches, and it added a new difficulty to those who had to 

 determine these, especially in mixtures."

JANUARY nth, 1906. 



The President in the Chair. 



Mr. J. W. Schoon, of Bayswater, and Mr. A. A. Dobson, 

 of New Maiden, were elected members. 



Mr. West (Ashtead) exhibited a booklet now being ex- 

 posed for sale on all the stalls and containing some sixty 

 admirable photographic reproductions of the life-histories 

 and protective resemblances in butterflies and moths. 



Mr. Hy. J. Turner exhibited four male examples of MorpJw 

 cypris from South America. 



Mr. South exhibited an enlarged drawing made by Herr 

 Max Gilmer of the ova of Pieris brassicce, showing the larva 

 just emerging from the shell. 



Mr. Tonge exhibited a capital photograph showing' the 

 life-history of Sesia (Macroglossa) stellatarum, ova, larva, pupa, 

 and imago. 



Mr. Main exhibited a long series of Noctua /estiva bred 

 last year from larvae collected in Lancashire, and a photo- 

 graph of an egg capsule of Periplaneta americana, the large 

 American cockroach which has become naturalised in some 

 of our factories in this country. 



Mr. Kaye exhibited a remarkable specimen of Agrotis 

 tritici bearing a close resemblance to Agrotis agathina. It 

 had been taken this year at Oxshott flying over heather in 

 company with A . agathina, and was a good example of syn- 

 cryptic resemblance brought about by the common habit of 

 resting on heather. The specimen agreed with A. agathina 

 in ground colour, in the pale costa, in the distinct dark 

 wedge-shaped marks near the outer margin, and in the dis- 

 tribution of the stigmata. These characteristics are simply 

 a strong development of characters which recur in the 

 species, and it was the simultaneous development of all of 

 them which gave the insect its strong likeness to A. agathina.
