ENTOMOLOGY. 



' Lepidoptera. — Mr. William Hewett writes that the lepidopterous fauna ot 

 Askham Bog is both numerous and interesting, and after twenty-three years experi- 

 ence of collecting in many parts of the country (and especially Yorkshire) he 

 unhesitatingly affirms it to be one of the best collecting-grounds in the kingdom. 

 The date of the excursion is somewhat early for many of the best species, still any 

 or all of the following species should be met with : — Anthocharis cardamines, 

 Argynnis selene, Pericallia syringaria, ladis lactearia, Acidalia remtitata, Et?i??ie- 

 lesia decolorata, Eupithecia castigata, E. albipicnctata and its var. angelicata (the 

 larvse feed on the flowers and seeds of Angelica sylvestris), E. valerianata , E. vul- 

 gata, E. absynthiata, E. tenuiata, Collix sparsata (for which Askham Bog is the 

 only Yorkshire locality, and here it is usually abundant, some seasons literally 

 swarming on favourite evenings, the larvje are to be found on Lysiniackia viclgaris) ; 

 Coremia feri-iigata, C. tinidentaria, Phibalapteryx lignata (abundant in the Bog, 

 and double-brooded, occurring in June and again in early August), Cilix spinula, 

 Cyniatophora duplaris, Acronycta tridens, A. psi, A. leporina var. bradyporina 

 (fairly common at sugar on favourable nights), A. megacephala, A. runiicis, A. men- 

 yanthidis, Leucania lithargyria, L. ptidonna (this local species is usually very 

 common both at sugar and flying over the sweet gale), L. imptira, L. palleiis, 

 Xylophasia lithoxylea, X. siiblustris, X. hepatica, Apamea getnima, A. iittatiimis, 

 Miana strigilis, M. fasciuncula, M. literosa, M. fiirnncula, M. arcnosa, Grani- 

 mesia trilinea, Noctiia augur, N. plecta, JV. c-nigrum, N. brunnea, N. festiva 

 (some very pretty forms of this variable species may be taken from amongst the 

 swarms that frequently come to sugar), N. rubi, N. baja,- larvse of Tceniocaiiipa 

 popuhti on aspen and poplar, larvse of Epwida viniinalis on sallow (York and 

 indeed northern larvae generally of this species produce some beautiful melanic 

 forms), Hadena adiista, H. dentina, H. suasa (usually very common at sugar), 

 H. thalassina, Cziciillia iimbratica , Hydrelia unca (one of the many Askham Bog 

 specialities, and frequently abundant on the wing in the early morning and evening). 

 Very common species have been omitted from this list. 



Coleoptera. — The Rev. W. C. Hey, M. A., writes that March is the best month 

 for Hydradephaga at Askham Bog. It is very doubtful if Hydroporzis scalesianiis, 

 H. oblongus, Agabus iiliginosus, or H. rufifrons will be found in June. But 

 many good things will still remain, e.g.,H. deco7'atiis, H, uvibrosus, H. vittula, 

 H. pran^daris, Liopterus agilis, Agabus unguiculaj'is , A. abbreviatus, and C. grapii. 

 This is the time to look for Hydaticus transversalis and Hydroena palustris , but they 

 have not occurred for many years. Bagoits peti o (only known as British by five 

 examples from Askham Bog) may be looked for in wet moss at the margins of large 

 shallow ponds. Dytiscns dimidiatus is a March insect, but the equally rare D. 

 circimicinctits might still be found in the deepest parts of the ponds near the middle 

 of 'Chandler's Whin.' Many species of Philhydrida will abound, including the minute 

 Liinnebius picimts. The handsome Donacia lemnce affects the flags in a large pond 

 which runs at right angles to the railway line. The 'jungle' has yielded among 

 other good things, Aromia moschata, Polyopsis prceusta, Bradycelhis placidus, and 

 Crypiocephahis labiatus. Oodes helopioidrs has often been found in wet moss. 



Other Orders. — No records.
