specimens of the plants Cotyledon umbilicus and Scduui cuigli- 

 cum sent to him by Mr. Rowden, from Exeter. A discussion 

 arose as to the distribution of the former plant, and it was 

 generally considered to be confined to the south-west and 

 western districts at no great distance from the sea, and not 

 to be found at all further east than Hampshire. Mr. Step 

 remarked that several plants had practically the same area 

 of distribution, such as Sibthorpia, two of the heaths, and 

 one or two species of clover. Dr. Chapman called attention 

 to the fact that the Cotyledon was by no means restricted to 

 the coast on the Continent, being found commonly in many 

 parts of the Alps. 



Mr. R. Adkin exhibited the living larvae of Acidalia 

 marginepunctata feeding on yarrow, and stated that previously 

 he had always been unsuccessful with the breeding of the 

 species. He remarked that the larvae seemed to be much 

 removed in form from the usual Acidalid larva, and that this 

 fact seemed to portend the breaking up of the genus at no 

 distant date. 



Mr. Kemp exhibited series of the following Coleoptera. 

 taken on the banks of the canal at Byfleet on June ist, 

 during the Society's field meeting •. — Rhagiuin bifasciaiuiii 

 (confluent spotted var.), and fine series of Donacia bicolora, 

 D. sericca (black var.), D. semicuprea, D. simplex, D. cinerea, 

 and D. discolor. 



Dr. Chapman exhibited the curious fungus Geaster limbatiis, 

 the starry puff-ball. He also exhibited the pupating burrow 

 of Scardia boleti. Their peculiarity consisted in a specially 

 constructed trap-door. The burrow is of some length, and 

 the cocoon proper occupies the lower half or third of the 

 burrow. The surface opening of the burrow is a loosely 

 constructed dome of silk and debris, but the top of the 

 cocoon proper is a trap-door, made of scraps of fungus, 

 rotten wood, or whatever the burrow is made in, embedded 

 in a dense mass of silk, the whole forming a circular disc of 

 some thickness, firmly attached to one side of the burrow so 

 as to form a hinge ; loosely elsewhere, so that the pupa easily 

 thrusts it open, though it is less easily forced inwards. 

 There is often a bend in the burrow at this point, purposely 

 arranged to allow the trap-door to fall well back out of the 

 way of the pupa. As a cocoon with a trap-door, that of 

 Lagoa crispata was instanced, and specimens exhibited ; in 

 this cocoon, which roughly resembles one of E. lanestris 

 or H. prasinnna, there is a trap-door, woven of silk, hinged 

 at one side, loosely attached at the other. The cocoon is
