Mr. Carr exhibited examples of C. fliicUiosa, C. duplaris, 

 and Boarmia repandata, with nice var. conversaria forms, all 

 from the Wye Valley ; he also showed the latter form from 

 the New Forest, and stated that he had never obtained the 

 dark form of this species in the latter locality. 



Mr. Cowham exhibited a white specimen oiRiimia cratcegata. 



Mr. Step exhibited on behalf of Mr. W. J. Lucas a speci- 

 men of the rare fungus, Cordyceps ophioglossoides, and its 

 host, Elaphomyces gramdatus, from Oxshott, and pointed out 

 that the Cordyceps is a member of a genus that is specially 

 interesting to entomologists, from the fact that several 

 British species are known to attack Lepidopterous pupae 

 underground, whilst a New Zealand species produces the 

 well-known phenomenon called the vegetable caterpillar. 

 C. ophioglossoides attacks the little-known hart-truffle {Elapho- 

 myces gramdatus), a subterranean fungus that under the 

 doctrine of signatures had formerly a reputation as an 

 aphrodisiac in rustic medicine. He also showed the fungus 

 Rhizina inflata, one of the Discomycetes, which Mr. Lucas 

 had found on burnt ground near the Black Pond. Like 

 Elaphomyces, it is parasitic on the roots of young conifers, and 

 so destroys great numbers of seedling pines. It is very 

 abundant this season in the pine woods on Ockham Common. 



Mr. Alfred Sich exhibited specimens of Coleophora chalco- 

 gramuicUa, and read the following note : 



" I exhibit two specimens, male and female, taken in coptda 

 at Richmond, Surrey, on August 14th, igog. The female 

 laid a few eggs, and I have now five larvae feeding. For the 

 first few days of their existence they mined the leaves, but 

 have now cut out minute cases. This species was first 

 described by Zeller in i83g, but not taken in Britain till 

 1857, when Mr. T. Wilkinson discovered the larvae near 

 Scarborough. I believe the species has not been taken 

 previously so far south in England." 



Mr. Turner read a paper entitled " Our Authorities," Part 

 II, and exhibited a number of volumes of the works referred 

 to by him (see p. 21).
