8 THE entomologist's RECORD. 



the footway and half soaking the pedestrian who dared to cross over. 

 The Devil's Bridge is a befitting name on a day like this, for, as we 

 remarked to each other, there might have been forty million imps 

 struggling for the mastery in that wonderful scene. 



But to return to the more sunny side of the tunnel ; the morning 

 at first was dull, and as we ascended the Pass a few Erebia ceto were 

 taken, together with K. lappona as usual ; a single specimen of E. (jorge 

 with very black underside found its way into one of my boxes near 

 the top of the Pass. Parascotia trepidaria likewise fell a victim, as 

 also did P. quadnfaria lower down on the other side ; of Larentia 

 caesiata I took several specimens quite typical, and a bad Brenthis 

 euphrosi/ne was the the only one of its genus at the higher level, and 

 on the way down towards Airolo two quite fresh A, wjlaia saluted us, 

 whilst a single Aporia crataegi and a single Colios phico)iione made the 

 acquaintance of our nets. One very worn Parart/e viacra showed 

 that this species was nearly over. Among the Lycaenidae that we 

 saw or caught as we neared Airolo, one or two examples of Heodes 

 virjjaureae or Chnjsop/taniis hippotho'e danced from flower to flower 

 in a certain military area that was so hemmed in and encircled with 

 barbed fencing, that it was quite impossible to get through anywhere, 

 and they were not sufficiently near to name with certainty, but from 

 the brilliance of the copper, I incline to think they must have been H. 

 vinjanreae. One Poh/onimatiis Jiijlas, and a nice pair of C. seiiiiargus 

 were the only blues that we saw and caught. Zi/t/aenidae, usually so 

 plentiful all over Switzerland, were here, and particularly in the 

 Hospenthal, remarkable by their absence. At Airolo we took Anthro- 

 cera purpuralia vav. nKhigena, A. lonicerae, and A. tranaalpina. After 

 a pleasant afternoon tea, and after posting various Airolo postcards to 

 our several friends, we made our way to the station hard by in 

 brilliant sunshine, but alas, emerged on the other side of the Gotthard 

 Tunnel into a downpour of rain. However, the rain in no way 

 damped the enjoyment of the day, and the sight of the Reuss from the 

 Devil's Bridge was fully Avorth the inconvenience of the rain, for 

 though I have seen most of the largest waterfalls of Norway, yet the 

 Reuss on this day will ever have a niche ot its own in my memory. 

 The Doctor and I spent another day around the Ober Alp See, mostly 

 on the mountain to the north-west of the Lake, and though our 

 list of captures was not great, it was, nevertheless, most enjoyable, for 

 in addition to the scenery and insects, the Doctor is such a delightful 

 companion that time goes quickly with him. As we went up the 

 steep bye-paths towards the Ober Alp we found ourselves beside a 

 deep gully with a running stream and saxifrage in abundance, and 

 the sun greeted us warmly as we emerged on to the bridge above, so 

 we halted to admire the view, and as we looked there appeared a 

 Parnassius below on the saxifrage, doubtless, P. delink, then another, 

 and another, until the temptation was too great, so down I went to try 

 my luck, and as I came back with half a dozen or so in my cyanide bottle, 

 the Doctor said, " I believe P. deliuH must always lay its eggs beside 

 running water," and to this 1 agree entirely, I have never seen it laying 

 except on saxifrage that, I believe, must at times be wholly under water. 

 In the Roseg Valley, where the species occurs very plentifully, and 

 where I have watched them laying, I was quite certain that those 

 plants must be under water considerably at the melting of the snow,
