var. Alecto — a single specimen of an Erehia which I saw at the end of the Arolla 

 Glacier (about 7,000 ft.), and, after a hard run over the stones of the terminal mor- 

 raine, secured, turns out to belong to tliis species : E. lappona — this species had the 

 highest range of any, according to our experience ; it occurred tolerably common 

 about the higher slopes of the Col du Torrent, and also on the top of the pass (about 

 8,000 ft.) ; in descending from the Bella Tola I caught one specimen on the snow at 

 about 9,000 ft., and saw others at nearly the same elevation ; it was common on the 

 Furka : E. Tyndarns — this species we only met with on the Col du Torrent, at from 

 about 6,500 ft. upwards ; it was not common : E. Ligea ? — I believe that several 

 Erebias, from Evolena and Vissoye, are referable to the true Ligea : E. Euryale 

 — being common at Vissoye and Evolena, in the valleys, and a few in Arolla Valley 

 and the Furka. Chionohas Aello — I caught two specimens in the Val d' Arolla, at 

 about 6,000 ft., and afterwards another in the Val d'Annivicrs at the foot of the 

 Col du Torrent, at about the same elevation ; Sclater found it commonly on the Furka, 

 and secured both sexes. Satynis Hermioiie — this fine species was common about 

 Vissoye, particularly frequenting the slopes of some dry rocky ground in the valley, 

 exposed to the sun ; it has a sailing Sibylla-like flight ; also in the Turtman Thai : 

 S. Acicea, var. eordula — this species was also common at Vissoye, occurring in the 

 same localities as the last, but nearly all caught were males. Pararge Mara — this is 

 one of the commonest butterflies in the Swiss valleys, at moderate heights ; it loves 

 to rest on the surfaces of rock overhanging the roads, and on walls, &c., exposed to 

 tlie sun, starting out moderately like a grayling, the grey under-surface matching 

 well with it chosen haunts : P. Hiera — we were apparently too late for this species, 

 only securing a few worn specimens in the Val d'llerens, between Evolena and 

 Arolla. Ccenonym'plia Satyrion — this pretty little " heath " was common at Arolla 

 on damp ground, but also occurred more sparingly around Arolla, in the Turtman 

 Thai, on the Col du Torrent, and on the St. Grothard route ; the males were much 

 commoner than the more brightly coloured females. Syricthiis carthami — not com- 

 mon ; a few in the Val d'Anniviers, at Arolla, Vissoye, and Zinal : S. alceits ? — ■ 

 Vissoye and on the Bella Tola, but I am not sure that the specimens are rightly 

 determined, owing to the diiBculty of this group : S. cacalicB — sparingly at Vissoye 

 and Evolena, but tolerably common at higher elevations on the Col du Torrent, the 

 Bella Tola, and Furka : <S'. Sao — one at Vissoye. Nisoniades Tages — abundant, flying 

 over wet ground, at Arolla. — W. A. Foebes, St. John's College, Cambridge : 16^/t

Von Harold's remarks on Japanese Hydrophilidce. — Hcrr von Harold, in his 

 Beitrage zur Kafer-fauna von Japan (Berl. ent. Zeit., 1878, p. 69), gives a note on 

 these insects, which seems likely to cause a good deal of confusion to those who may 

 follow it. He suggests that Megasternum distinctum, Sharp, may probably be the 

 same as Motschoulsky's Pachysiernum hcemorrhoiim ; though it would be difficult to 

 suppose, he adds, that such a suificient observer should have overlooked the absence 

 of emargination on the front tibige. This is a curious remark for such an ac- 

 curate naturalist as von Harold to make, for, in my description of M. distinctum, I 

 said expressly that it " has the anterior tibiffi simple at the extremity." 



This oversight of Harold's is accompanied, however, by a second equally great 

 one, viz., that Motschoulsky expressly states that P. hcemorrJiouni has the front tibiae 

 emarginate ! His words are " Forme ovalaire attenue'e dcs Cryptopleurum, mais avec 

 les jambcs anterieures echaucrees sur leur face exterieure."
