bole liberally decorated with the large corky fungus, Fomcs 

 vegctus, some of the specimens measuring more than a foot 

 across, and clearly exhibiting its perennial character by 

 several strata of annual growths. 



Mr. R. Priske has since forwarded a short list of the 

 Coleoptera taken by him : 



Brachinus crepitans, Telcphorus nigricans, T '.* Immorrhoidalis, 

 Lacon murinus, Mclanotus rufipes, Corymbitcs holosericens, 

 Cistelaluperus andvar. fcrniginca, C. murina, Chrysomclapolita, 

 Pliytodccta pallida and RhyncJiitcs ccncovircns. 



JUNE itf/i, 1907. 



Mr. Lucas exhibited a specimen of Panorpa germanica, one 

 of the scorpion flies ; the Trichopteron Leptoplilebia sub- 

 marginaria, from Fetcham ; and from Netley, the Myxogastcr 

 or slime-fungus, Rctinavia maxima. 



Mr. Hy. J. Turner exhibited the living larvae of Colcophora 

 discordella, sent to him by Mr. Wilkenson, of Workington. 



Mr. West, of Greenwich, exhibited eggs of the night-jar, 

 the rare Coleopteron Triplax lacordairei, and the uncommon 

 Hemipteron, Verlusia rlwmbca, all from Darenth Wood. 



Dr. Chapman exhibited living larvae of Calocampa exolcta 

 in their pre-final instar, and stated that they were now feed- 

 ing on sallow, having refused their first food, dandelion, which 

 they only consumed when in a shrivelled and stale condition ; 

 and two varieties of Papilio machaon, bred from continental 

 pupae. One looked very yellow, the other rather black. The 

 first one might be described as having an excess of the black 

 marginal line, as evidenced by its continuing round the outer 

 margin of the anal orange ocellus, and a great or complete 

 defect of the black line bordering the inner side of the great 

 dark submarginal band ; this increases the yellow and is 

 obviously in want of the black line, basal to the orange 

 ocellus, and the black spots in the apical yellow streaks of the 

 fore-wings. The orange ocellus has quite a remarkable 

 appearance in consequence of these variations. The other 

 specimen is more remarkable for the form of the fore-wings 

 (costa very arched towards the apex) than for markings. It 

 has an excess of dark area, but has in places some paleness 

 of the dark scales. 



A discussion took place in which numerous species were 

 cited as, in the larval stage, preferring their food to be more 

 or less stale, or even decomposing ; among them were one
