28o Yorkshire Naturalists at Dent. 



• 

 fewer, and above that ceased. The Common Frog was noticed to be much 

 more numerous on the upper drier reaches of Whemside than it was on 

 the wetter slopes lower down ; in fact, one was found within thirty yards 

 of the highest cairn . Evidently after spawning these amphibians had 

 made for the higher and drier ground. Trout, in the river, was the only 

 species of fish noted. 



MoLLUSCA. — The following Mollusca were collected by Mr. Greevz 

 Fysher and verified by Mr. John W. Taylor : — Arion aterv. welanocephala, 

 Helicigona arbustorum, Hygromia ritfescens, H. hispida, Helix nemoralis 

 V. libellula (12345), Vitrina pellucida. Hyalina cellana, H. alliaria, 

 H. nitidula, Pyraniidula rotundata, Zua lubrica, Clausilia bidentata. 

 One example of Ancylus fluviatilis was observed in a small s.tream running 

 into the River Dee. 



Dtptera. — Mr. Chris. A. Cheetham's observations are as follows : — The 

 weather was unfavourable for Diptera, but in Great Blake Ghyll fungus 

 gnats and small limnobids were plentiful and some interesting species 

 were taken. Mr. F. W. Edwards kindly identified these, and states that 

 one species, Excchia con finis Winn, is new to the country. Ormosia 

 (Rhypholophus) aciculata Edw. was in plenty, this is the insect recorded 

 as /?. nodulosus Mcq. in The Naturalist, 1921, p. -254. | Two Boletinas 

 were taken, B. trivittata Mg. being an addition to out list, and B. inerniis 

 Lunst. Phronia forcipula Winn, and A llodia longicornis are also additions 

 the latter 1 have had previously from Famley and Austwick. Erioptera 

 Juscipennis Mg. (also from Beverley, Gormire, Austwick and Famley) is 

 unrecorded for the county. Amalopsis immaculata Mq. and Dicranoniyia 

 chorea Mg. complete the Great Blake Ghyll captures. 



On the summit of Whemside the species were mostly very common low- 

 land types, but two Empids, E. lucida Ztt. and E. Snowdoniana Collin, 

 are the species generally found in abundance on Cloudberry blooms. 



CoLEOPTERA. — Mr. W. J. Fordham reports : — Mr. H. H. Wallis and 

 the writer investigated the beetle fauna of Great Blake Ghyll and the 

 adjoining portion of Whemside on the Saturday. The following day was 

 devoted to the immediate neighbourhood of Dent, and was restricted 

 to the valley of the river, with a short ramble up Flintersgill. A total 

 number of g8 species (not including varieties) was obtained. There were 

 no new county records as far as the species are at present determined . 

 Help was rendered by several other members of the Union, as noted in the 

 following remarks on the more noteworthy species : — 

 *Notiophilus substriatus Wat. An interesting black form of this insect 

 was taken, with apices of the elytra of an orange hue. 

 Bembidium atroviolaceiim Daf. (stonioides Dj.). Two examples imder 



stones by the river in Dent dale. 

 B. decorum Pz. Also occurred here. 

 B. atrocoeruleum Steph. Under stones by the stream in Great Blake 



Ghyll. 

 Patrobus excavatus Pk. Occurred at about 1,200 ft. on Whemside. 

 The montane assiniilis Chd. was not seen, though it occurs freely 

 on Inglcborough. 

 Pterostichus vitreus Dj . Whemside, about 1,800 ft. (one). 

 *Metabletus foveatus Geoff. Great Blake Ghyll. 

 Hydroporus rivalis Gyll. Was taken in the stream at the head of Great 



Blake Ghyll. 

 H. borealis Gyll. (davisi Curt.). .Abundant in the river in Dent dale, 

 and easily captured by hand as it swims among the stones at the 

 edge of tlic river. 



f This and otliers will be described by Mr. lulwards in a future part 

 of the Transactions of the Entomological Society. I have a number of 

 additions to the Yorkshire list awaiting this publication.
