YORKSHIRE NATURALISTS AT KNARESBOROUGH. 147 
{larvze), None of these call for any special notice, all being common 
and of general distribution, the only exception being Asthena blomeri, 
of which Mr. Hewett noticed one specimen at rest on the bole 
of an ash tree, on the wooded slopes of the Nidd Valley. The 
species occurs in abundance at Sledmere, and also sparingly at Castle 
Howard, Coxwold, and Helmsley. Whilst at Knaresborough on the 
3eth April, 1894, he noticed Pieris rapa, P. napi, Anticlea badiata, 
Scoparia ambigualis, Crambus tristellus, and Crambus culmellus 
For the correct determination of the three last-named insects, 
Mr. Hewett was indebted to Mr. G. T. Porritt, F.L.S. Mr. Hewett 
further mentioned that a fine living female specimen of Sirex 
gigas was given to him by a keeper who had just caught and impaled 
it. In this connection it will be of interest to mention that Mr. T. H. 
Blakey, Starbeck, has taken the following Lepidoptera in the neigh- 
bourhood of Knaresborough: Pieris brassicae, P. rapa, Anthocharis 
cardamines, Colias edusa, Vanessa urtice, V. atalanta, V. io, 
cardut, Satyrus janira, Chortobius pamphilus, Polyommatus phleas, 
Lycena alexis, Thanaos tages, Smerinthus populi, S. tilie, Sesia 
tipuliformis, Cossus ligniperda, Hepialus hectus, H. humuli, Zygena 
filipendule, Arctia caja, Liparis auriflua, L. salicis, Orgyia antiqua, 
Odonestis potatovia: and soda vg vinula. ‘Thirteen species of 
Spiders were recorded by Mr. 
For the Botanical Section Mr. 4 H. Pawson, its Phanerogamic 
Secretary, reported on the Phanerogams as follows:—The riband- 
like tract of magnesian limestone which runs N.W. and S.E. through 
Yorkshire attracts the botanist as the heather does the honey-bees, 
and it is no doubt greatly on our account that the geologists have 
such frequent opportunities of studying these singularly unfossiliferous 
rocks. Our rambles on this lovely July day did not extend much 
beyond a mile from the town. The Wallflower of the truly wild type 
and the rare Nottingham Catch-fly were observed on the cliffs above 
the river, fortunately in places inaccessible to would-be depredators. 
Allium oleraceum is here in marvellous abundance, and there is 
a good patch of Salvia verbenaca in a sunny corner. Anthriscus 
vulgaris was again found, as at Pontefract, this time on Grimbald’s 
Crag, where Geranium pusillum was growing. ‘The time was short 
and a thunder-shower hindered us, otherwise we should have had 
a longer list of plants than the following one, which was the result of 
the day’s excursion :— 
Helleborus viridis. Hypericum montanum. 
Cheiranthus cheiri. Geranium pratense 
Silene nutans. Geranium pusillam, 
Silene noctifiora, Geranium columbinum, 
Sagina apetala. Geranium sanguineum.
