PORRITT : AN ENTOMOLOGICAL EXPEDITION. 



fear that 7iigrod?icta was becoming scarce. After our return home 

 we suggested this to a Liverpool lepidopterist, who has had great 

 experience with the species, and were then at once informed by him 

 that as three collectors had spent about a fortnight on the very 

 ground, just before our going there in June, working every available 

 yard of it for this species, and so taking plenty, our informant's 

 surprise would have been great if we had found any ! In the middle 

 of August, too, we were probably a fortnight too early for the variety 

 unicolor of Cirrczdia xerampelina^ which used to be not uncommon 

 in the Nunnery Grounds near Douglas, and doubtless equally so in 

 other parts of the island, as its food (the ash) flourishes luxuriantly, 

 and is undoubtedly the tree of the Isle of ]\Ian. In the list of species 

 for the Isle of Man, I have also included those I took when there 

 from the 17th to 20th June during the past season, as well as several 

 Trichoptera I took several years ago.

Vanessa io. Satyrus cegeria^ and about a dozen other species of 

 butterflies occurred, but none of any rarity. Satyrus semele seemed 

 equally at home either on mountains or sandhills, and was common.

 linariata, larvae in seed capsules of Linaria vulgaris ; E. minutata ; 

 E. subfulvata ; E. p2unilata \ E. nanata ; Coremia zmidentaria^ 

 abundant everywhere ; Scotosia dubitata, on ling flowers after dark, 

 high upon the Zvloel Leys ; Cidaria picata^ about rocks between Pen- 

 maenmawr and Conway \ C. pj'unata, abundant about old currant or 

 gooseberry bushes in gardens ; Fygcera bucephala, larvae in profusion 

 on sallows ; Charceas graminis. very fine on the jNIoel Leys ; Miana 

 literosa ; Agrotis porphyrea \ Tryphcena ja?ithina, abundant every- 

 where, apparently much more so than T. pro nub a ; Noctua umbrosa ; 

 Xanthia cerago \ Anarta myrtilli^ larvae ; Mania maura ; Stilbia 

 anoniala, common on, but near the base of, the Moel Leys; Pyrausta 

 piirpuralis \ Endotricha flammealis ; Scoparia mercuralis ; S. truiici- 

 colalis^ a Scoparia occurred rather commonly in one hedge at Pen- 

 maenmawr, which seems to be a pale form of this species ; Crambus 

 geniculellus ; Pero?iea spo?isa7ia ; Tortrix unifascia7ia ; Dictyopteryx 

 holmiana ; Grapholitha 7iisa?ia ; Spilo7iota i7icarnata7ia, this pretty 

 species occurred in profusion among Eosa spinosissi77ia in Conway 

 Bay, and on the opposite sandhills near Llandudno ; Fhoxopteryx 

 limdana^ common ; Xa7ithosetia ha77iana ; Conchy lis inopia7ia] Aphelia 

 pratana, abundant ; Hypolepia radiatella^ most abundant, and almost
