NOTES — ORTHOPTERA AND LEPIDOPTERA. 5 



On dissecting a portion, I further found two or three perichaetia, 

 the characteristic leaves of which were quite perfect, enclosing one 

 or two antheridia, somewhat shrivelled, with their accompanying 

 paraphyses. 



Who were the makers of this boat, and who gathered this moss 

 for caulking purposes, I have not seen definitely stated ; it may have 

 been ancient British, or it may have been older. If made in the 

 immediate neighbourhood — which is more than probable — it may 

 have been made, and probably was, by men living during that period 

 when the vale of Ancholme was covered by that forest of oak, yew, 

 hazel, birch, etc., which grew just above the gravels and boulder-clay 

 of the drift period. Since then it would appear that the land began 

 gradually to sink, the forest disappeared, its place being occupied by 

 a swamp, and eventually a lake. But this is a question which can 

 only be settled by those who know the district and the level at 

 which the boat was found. I, for one, should be glad to know 

 whether anything — and if anything, what — has been attempted 

 towards determining this question, which is a most interesting one. 

 At any rate, be the period what it may, Plagiothecium undulatum 

 must then have been found in the district in considerable abundance. 



NO TE— ORTHOPTERA. 



Some Lincolnshire Orthoptera. — While in Lincolnshire in August this 

 year I took seven species of Orthoptera, which have since been obligingly 

 examined by Mr. Eland Shaw, viz. — Stenobothrus viriduhis L. ,S. bicolor Charp. , 

 3". elegans Charp., Gomphocerus maculatus Thunb., Tettix bipunctatus L,., Tham- 

 notrizon cinereus L., and Platydeis raslii Hagenb. Steuobol/incs viridulus was 

 abundant in and near an old chalk-pit at Haugham Pasture, where also one 

 specimen of Tettix bipunctatits was obtained, and on the bramble -bushes near 

 Tkamnotrizon cinereus was numerous. Stenobothrus bicolor, S. elegans, and 

 Gomphocerus maculatus were taken on the coast sand-hills at Mablethorpe. 

 Platydeis raslii was plentiful amongst the coarse grass on the coast sand-hills at 

 Trusthorpe. This species was taken by Mr. Saunders, in August 1886, at Heme 

 Bay, which, as Mr. Shaw informs me, appears to be the only other locality from 

 which it has been reported recently.— H. Wallis Ke\v, London, 8th Oct., 1888. 



NO TE—LEPID OPTERA. 



Scoparia ingratalis in Yorkshire. — On the 26th of June last, in a rough 

 field beyond and adjoining Pennyspring Wood, Huddersrield, I knocked down a 

 Scoparia which, from its whiteness when on the ground, at once attracted my 

 attention. A closer examination at once revealed a beautiful specimen of 

 ingratalis, and by beating an old whitethorn hedge bordering the field, I soon 

 secured several more examples. S. ingratalis is now usually, and very properly 

 so, considered to be a form of S. pyralalis, of which the ordinary form also 

 occurred with the variety on the occasion of my taking the specimens ; but 

 S. ingratalis has never before been recorded from Yorkshire, nor, so far as I 

 remember, anywhere than in the extreme south of England. It has always been 

 associated in my mind with the chalk of Kent and Sussex, and that it should occur 

 here on a heavy clayey soil, where the tendency in lepidoptera when they do vary, 

 is almost always in the opposite direction to melanism, is very singular. — Geo. T. 

 Porritt, Huddersfield, December 15th, 1888.
