ova of four species of the genus Coleophora obtained recently 

 by Mr. H. J. Turner. They were in sitii on the food plant 

 of their respective species, and an enlargement of the micro- 

 pyle of each was also shown. The species were C. hcemero- 

 biella, C. solitariclla, C.fusccdinclla, and C. viminetclla. 



Mr. Alfred Sich exhibited living specimens showing a case 

 of Miillerian mimicry between the Gelechiid moth, Recurvaria 

 (Aphanaula) nanella, and a Hemipteron, Phytocoris tilice, which 

 Mr. West stated to be very common on lime and other trees, 

 and very variable. Mr. Sich stated that both rest on the 

 bark of fruit trees during July, and from a short distance 

 bear a great similarity to each other, the black, white, and 

 grey markings being somewhat similarly arranged. He also 

 exhibited a curious specimen of the genus Pygcera, and 

 suggested that it was possibly a hybrid between P. pigra and 

 P. curtula. This was bred April 20th, 1906, and the larva 

 was taken with others from aspen on the occasion of the 

 Society's excursion to Chislehurst, September 16th, 1905. 



The following is a description of the insect : The chief 

 difference consists in — firstly, markings : the second trans- 

 verse line is so far from the base that it almost occupies 

 the position of the third line in normal specimens ; the third 

 line scarcely visible, except towards the dorsal margin ; the 

 fourth line very much straighter; the second and fourth lines 

 very pale, and twice the breadth of pigra type. Secondly, 

 colour : the spaces between the second and fourth line on the 

 costa and the second and third line on dorsum form a tongue 

 of almost black colour, whereas in normal specimens this is 

 dark purple-grey. The red-brown patch beyond the fourth 

 line is extended to twice the usual width, and is much deeper 

 in colour, and the nervures, as they pass through it, are black. 

 Shortly, the space between the first and second transverse 

 lines is double the usual width, the second and fourth trans- 

 verse lines are more than double the usual width, very pale, 

 and the space between them mostly occupied by an almost 

 black, tongue-like mark. The chestnut colour is extended to, 

 and almost envelops, the submarginal row of black dots, with 

 a conspicuous pale blotch at the anal angle. 



Mr. Sich further showed the ova of Lyccena alcon on the 

 Marsh Gentian {Gcntiana pneumonanthc) , together with a 

 photo-micrograph by Mr. F. Noad Clark.
