198 THE entomologist's record, 



condition, to hang on a (entainea or other flower on the banks below. 

 F'arar;ie maera, too, was also frequent, though often badly torn. The 

 two common Pierids — Fieris hraxsicae and P. rapae — were still abundant, 

 so also was P. napi, but of the most normal form. Higher up, the pine- 

 wood crossed the road, and among the flowers by the roadside, a few 

 worn lireiitJiis euithiosi/ue still flew with plenty of B. amathusia and an 

 occasional B. rnn. A steep flowery bank leading up to the rocks above 

 suggested a halt for a few moments, for here many species were 

 common, Parnassiiis apullo fairly so, although the lower Engadine 

 valleys — at Zernetz, Sus, Lavin — appear to produce this species only 

 very sparingly, several species of blues, Erebia (joante, captured almost 

 at the commencement of our walk, and other insects, among which 

 Erebia aethiops may be mentioned. The best capture here, however, 

 was Lycaena arion, two small dull-coloured examples, the ^ very thinly 

 scaled with blue, the 5 greyish, with only a tinge of blue scaling towards 

 the basal part of the inner margin. It would be interesting to know 

 if this were the ordinary form of the species in this district, as it is 

 very different from those we have captured in many places elsewhere, 

 at any rate we propose to call it var. (or ab.) ofenici. Two or three Aporia 

 crataefii 2 s, the central area of the forewings quite glassy and trans- 

 parent with wear, were observed, and Ariii/nnis odippe was frequent. 

 Of the Anthrocerids, only Anthiorera lonirerac and A. tranmlpina were 

 observed, but these were very abundant, the former often with a 

 distinct orange tone in the colour of the hindwings. As one walked 

 along several moths were netted, Eiib"Ua bipinictaria being especially 

 abundant, whilst the ^ Dasi/dia obfiiscata were exceptionally large 

 and dark, and this was so throughout the Avhole length of the Pass, 

 but more interesting to us Avere examples of E]none res]iertaria, 

 and Tlu'ia obeliscata, whilst Litlmsia i/riseula and L. Inrideola were 

 very frequent on flowers. The first rocky cutting was much 

 patronised by Erebia <ioaitte, but one or two worn Erebias netted 

 for inspection w^ere puzzling as being not altogether satisfying 

 for that species, but it was not till a good hour later that we 

 recognised that we bad netted among the E. tptaiite a worn example or 

 tw^o of the much rarer and local A', iicrine. Bnt we soon came out on 

 some meadows where mowing was proceeding, and, in one of these, as 

 yet uncut, upon the rank herbage growing round the source of a 

 bubbling spring, BrentJiia ino was very common, although few were 

 worth a pin, and here a pretty pale form of Eubolia )nensiiraria was 

 equally abundant. Worn Ci/aidris seiniar(/i(s, too, Avere not infrequent, 

 but we were evidently much too late for this species in fine condition. 

 Here, too, we captured a magnificent pair of newly-emerged Melitaea 

 phoebe, the ? of the large dark mountain-valley form, strangely the 

 only examples seen on the Pass. Passing a delightful moss-covered 

 spring where one was tempted to drink, one comes to a bend in the 

 road where a bridge crosses a stream that comes down a side valley 

 and here falls rapidly into the main one. On the banks of the 

 stream, a number of tiny water- rills oozed out, making little wet 

 patches that crossed a track that evidently indicated a short cut to a 

 dwelling higher up the valley, and these damp patches proved most 

 productive, for all the common blues of the valley were assembled here: 

 Plebeius ari/iis {aegoii) var. Idlliasi, worn, Ct/aniris seiniaryus, Hirsiitina 

 damon, Poli/onimatus icarus, Aricia astrarche, Ayriades coridon, and.
