which was considered by Mr. Stainton to be a dark variety of Glyphisia 

 crenata. 



The Hon. T. De Grey exhibited a series of Oxyptilus Isetus (Zeller), from 

 Brandon, Suffolk. 



Mr. M'Lachlan, on behalf of Mr. Tegetmeier, exhibited some nature-printed 

 butterflies, the bodies and antennae being painted by hand : they were so 

 admirably executed as to have been taken for hthographs, and were offered for 

 sale as such by an eminent firm. 



Mr. Blackmore exhibited a number of insects, chiefly Lepidoptera and 

 Coleoptera, the result of last winter's collecting in Tangier. Among the butter- 

 flies was a fine series of the true Anthocharis Euphaeno (Linn, sp.), a species 

 till recently mistaken. Among the Coleoptera was a curious monstrosity of 

 Pimelia scabrosa; the right-hand antenna was doubly furcate, or rather there 

 were two antennae, of which the two basal joints were united ; branching from 

 the third joint, the right hand fork was of normal form, but the left hand fork 

 was again furcate, a small two-jointed limb springing out (at the top, not at the 

 side) of the 8th joint of the fork {i. e. the 10th joint of the antenna). 



Mr. F. Moore exhibited cocoons of a Sagra from Bombay, collected by 

 Mr. Newton ; three cocoons with the beetles which had emerged therefrom 

 were shown in situ, and lay contiguous within a large swelling in the stem of a 

 creeper (Cocculus macrocarpus). 



The President read the following extract from a letter, dated "Sarawak, 17th 

 April, 1870," from Mr. A. Everett ;— 



" My brother has found two remarkable spiders. One, which we had not 

 the means of keeping at the time, was lying with its legs pressed closely 

 beside its body, and was white streaked with black in irregular fashion : when 

 he called me to see it, I looked closely but in vain for it, the only thing visible 

 on the leaf being apparently a patch of bird's dung ; when it moved, one saw 

 immediately what it was. The other is similar in colour and behaviour, but 

 seems to belong to a different genus, and the resemblance to the droppings of a 

 bird is not so completely deceptive. These would appear to be instances of 

 protective mimicry, and as such will perhaps be of interest to you. I have 

 another example, almost if not quite as evident : I had a caterpillar brought me, 

 which, being mixed by my boy with some other things, I took to be a bit of 

 moss with two exquisite pinky-white seed-capsules ; but I soon saw that it 

 moved, and examining it more closely found out its real character : it is covered 

 with hair, with two Httle pink spots on the upper surface, the general hue being 

 more green : its motions are very slow, and when eating, the head is withdrawn 

 beneath a mobile fleshy hood, so that the action of feeding does not produce any 

 movement externally ; the shape is oval, and the edges are fringed with tufts of 

 hair : it was found in the limestone hills at Busan, the situation of all others 

 where mosses are most plentiful and delicate, and where they partially clothe
