166 THE entomologist's RECORD. 



Splitting the stems of the tall marsh thistles for pupse, was a nasty job 

 and not at all successful, a single pupa of (Jchria ochracea, rather a 

 scarce insect in this neighbourhood, was all that rewarded my efforts. 



On August 15th I left Abertillery for my summer holidays, going 

 to my home at Bickley, in Kent, whore I stayed until September 2nd. 

 I did not attempt to do any sugaring, as it had been such a failure at 

 Abertillery and confined myself to searching fences and tree trunks 

 during the day and going round the lamps at night. Amongst the 

 butterflies Pieris biassicae, 1'. rapae and P. napi, Goneptenjx rhamnl, 

 Vanessa io, Coenonywpha pa)i)philus, Rumicia phlaeas and Polyovnnatus 

 icarus were all common, a few Pi/rameis cardni, Parartje vteyaera and 

 Awjiades sylvanas were seen. I did not see a single example of the 

 second brood of Celastrhia argiolus, which is generally common here in 

 August. 



Searching fences and tree-trunks gave Ilcpialus sylcina, Oyjijia 

 antiqiia (?s at rest on their cocoons), OpistJioyraptis Ititeolata 

 (common), Knnomus (jiiercinaria, K. alniaria, K. fuscantaria and K. 

 erosaria, Eupithecia vulyata (common), Xanthorho'e finctitata (in 

 abundance), Coremia ferrngata, Canipt(i(/ramina bilineata, Acidalia 

 vinjularia (common), Ortholitha bipunctaria, Thera variata, Drepana 

 falcataria, Lophoptenjx camelina, Asphalia diluta, Bryophila perla, 

 Xylophasia monoylypha, Charaeas (jrawmis, Luperina testacea (common), 

 Barathra biassicae, Triphaena pionuba, Xoctita plecta and X. xantho- 

 (jrapha (common), Tiliacea {Cirrliia) citrago, Calyinnia trape^ina, Phlo- 

 (fuphura iiieticnlosa, Plusia yamma, Ampldpyra trayupoyonis, Catocala 

 ■niipta, Cratnbus pratelliis, C. perlellKs, and C. yenicnleits (abundant). 



Insects were very common on most nights round the gas lamps. 

 Can any entomologist explain why light pays in some districts and 

 not in others ? I have gone round the lamps, m the Abertillery 

 district, night after night, in the middle of the season, without seeing 

 a single moth. By far the commonest insect round the gas lamps at 

 Bickley, during the last fortnight in August, was Cratnbiis yeniculeus, 

 every lamp gave three or four specimens, and on one lamp no less 

 than 15 were counted. Xoctaa xanthoyrapha came a good second. 

 This insect swarmed on one or two sultry nights. The following 

 insects were taken at light between August 16th and September 1st. 

 Onrapteryx sambiicaria, Opisthoyraptis luleulata (common), Ennunios 

 quercinaria and K. alinaria, Pcrizoina iiiiifasciata, Acidalia viryularia 

 and A. iiiaryine]iit)ictata, Kupitliecia obloityata (common). A', albipiinc- 

 tata, K. absinthiata, K. sobrinata, l\. linariata, E. pnlchellata, Corcniia 

 iDiidentaria and ('. fcrniyata, Xmitliorluie jiuctuata (common), ('ainjtto- 

 yraiiniia bilineata (common), Mesolenca occllata, Anaitis playiata, 

 Piepana binaiia, i'iiix ylaiicata, Lencania pallens, Hydroecia inicacea 

 and IL nictitans (common), Xylophasia monoylypha, Epineuronia 

 popularis (the J s were very common, 3 $ s were found at rest on 

 fences near lamps), Charaeas yraminis, Luperina testacea, Barathra 

 brassicae (common), Ayrotis pnta, Xoctua plecta, X. c-niyrum, X. 

 xanthiiyrapha and A', rnbi, L'irrhia citraya, I'hluyaphora meticiilosa, 

 I'liisia yainina, Ani]ihipyra trayopuyunis (common) and Catucala nnpta. 

 Amongst the "micros" were Crainbns yenicnlens (abundant), C. 

 pratelliis and C. selasellns, Pimiea furjicalis (connnon), I'yraiista 

 pnrpiiralis (common) and /'. ostrinalis, IJerbiila cespitalis (common), 

 Endotricha /lamniealis, Scopida ulirulis, S. lutealis (common) and S.
