Gibbs : Yorkshire Naturalists' Union at Masham. 19 



Psychomyia pusilla, abundant. 

 Hy dropsy che lepida. 



Other Trichoptera noticed included Leptocerus cinereus and 

 Tinodes wceneri, both common. Various species of Planipennia 

 were taken and the Odonata included a fine vEschna juncea, 

 a dragonfly apparently much rarer in Yorkshire than its near 

 relative ^E. cyajiea. 



A striking feature of the excursion, too, was the extra- 

 ordinary number of the fine Hymenopteron Sirex gigas which 

 were seen near the saw mills at Healey, probably at least 

 twenty specimens being seen which had recently been found 

 in the timber used at the mills. Scarcely any attention was 

 paid to the Lepidoptera, but Majiia maura, Melanthia rubi- 

 ginata, and other species were taken. 



Mr. E. Snelgrove, B.A. (Sheffield), writes as follows on the 

 Phanerogamic Botany : — The district examined by the botanists 

 during the three days of the meeting extends along the south 

 bank of the Ure, from two miles below Masham, up the 

 Burn, which flows through Colsterdale, to Birk Gill. The 

 records include 200 species of flowering plants, among which 

 maybe mentioned : — Campanula latifolia, C. glomerata, Hypericum 

 hirsutum, H. dubium, H.pulchrum, Geranium sylvaticum, Mimulus 

 luteus, Primula fariiiosa, Parnassia palusiris, Epipactis media, E. 

 palustris, Gymjiadenia conopsea, Listera ovata, Schcejius nigricans, 

 Carex pendula, C. Jlava, C. panicea, C. paniculata, C. remota, 

 Ononis spinosa, Pimpinella magna, and Rubus saxatilis. In Birk 

 Gill, Drosera rotundifolia, Vaccinium oxycoccos. Near Masham 

 also Actcza spicata and Saxifraga tridactylites. 



Amongst Cryptogams, Equisetum palustre , E. sylvaticum, Lyco- 

 podium selago, and an interesting list of ferns were recorded. 

 For this last, Mr. J. E. Clark is responsible : — Pteris aquilina, 

 Lo?naria spicant, Asplenium adiantum-nigrum , A. viride, A. ruta- 

 muraria, Athyrium filix-foemina, Polystichnm lobatu?n, P. lobatum 

 var. aculeatum, P. aculeatn?n var. lonchitidioides, Lastrcea oreop- 

 teris, L. filix-mas, L. spinulosa, L. dilatata, L. cemula, Polypodium 

 vulgare, Cystopteris fragilis, Phegopteris Dryopteris, P. poly- 

 podioides. Most of these were found in Birk Gill. There was 

 some remarkably fine Peltigera canina on the mosses of the 

 moist cliffs. The flowering plants were done carefully, but it 

 cannot be said that any serious attempt was made upon the 

 mosses, hepaticae, or lichens, for want of specialists. The 

 Botanical party were much indebted to Mr. W. A. Thwaites, of 

 Masham, for valuable guidance to suitable localities.
