(Sussex), July 28, 1917, on Inula dysenterica (Fleabane). 

 This is its first record on Fleabane, and all the specimens 

 were of a bright yellow and black colour when alive, and not, 

 as is usual, red and black. Though freshly emerged they were 

 quite mature, and moreover were ke])t alive for a long time 

 without changing colour in any way. A specimen from Box 

 Hill of the typical form, taken on Inula conyza (Ploughman's 

 Spikenard), May 7, 1909, was also exhibited for comparison. 

 It was previously only recorded from Senecio jacobae 

 (Ragwort). 



Photographs of Sawfly Larvae.^ — The Rev. F. D. 

 MoRiCE exhibited with the Epidiascope a set of photographs 

 (mostly taken from living specimens feeding or resting on 

 their usual food-plants) of the following Sawfly larvae :■ — 



Cimhex lutea, L., coiled up on Sallow, Abia fasciata, L., do. 

 on Snowberry, Phymatocera aterrima, Kl., on Solomon's Seal, 

 Rhadinoceraea micans, KL, on Iris, Empria (Poecilosoma) 

 luteola, KL, on Yellow Loosestrife, Eriocam/pa ovata, L., on 

 Alder, Nematus {Croesus) septentrionalis, L., in " threatening 

 attitude " on Birch, Pteronidea (Nematus) salicis, L., on Birch, 

 Trichiocampus viminalis, Fall., on Poplar. Also of a cast 

 skin, showing the Y-shaped spines, of a Periclista larva — ■ 

 probably melanocephala, F. ; and of the sort of " palisade " 

 ■ — a ring of little columns formed by the rapid drying of some 

 bubbly, froth-like secretion from the mouth — with which the 

 young larva of Lygaeonematus compressicornis, F., surrounds it- 

 self while feeding on a leaf of black Poplar. (Plates B and C.) 



The Chairman observed that Sawfly larvae in moulting 

 attach themselves by the tail to a gummy substance pre- 

 viously deposited by them, because they have no hooks on 

 the terminal pad of the prolegs such as occur in the Lepido- 

 ptera; the true legs, which in the latter are generally used 

 rather as hands than as feet, are in the Sawflies provided with 

 claws sharp enough to penetrate the leaf.
