LurTON : The Lepidopteea of Arran.

As is frequently the case when in pursuit of insects, what appeared 

 to be a favourable spot or a good evening for them, turned out often 

 very badly. Sugaring was very discouraging at Brodick ; we sugared, 

 on two nights, palings for the distance of a mile at the side of a 

 plantation, and very near an open moor of heather, &c., and the only 

 result was one common Noctua. 



At Corrie we sugared on four evenings — twice in one place, and 

 twice in another, both times on low levels near the coast. One evening 

 we counted nine moths of the five commonest species that visit sugar, 

 and on the other three nights not even so many. Netting, both in the 

 daytime and in the evening, produced by far the most insects ; the 

 best we got in the evenings were Dasydia ohfuscata, Pelurga comitaia, 

 Hepialus velleda, and Agrotis vallige.ra. Obfuscata is, I think, the best 

 insect we took ; this we found a mile from Brodick, on the Lamlash- 

 road, on a small piece of moorland, and for about half an hour on two 

 evenings it was tolerably abundant. During the rest of our stay we 

 only met with three specimens in other localities — one at rest on rock, 

 and two flying. Gomitata occurred one evening on the sandhills at 

 North Sannox, and we ca[)tured ten. Valligera also occurred there, 

 and on one evening only we took five, over flowers. Velleda was 

 tolerably abundant on several evenings. 



During the daytime, by searching trees, palings, &c., we found one 

 Hadena contigua, several Cymatophora duplaris one Notodonta camel- 

 ina, one Ellopia Jasciaria, Venusia cambrica abundantly, one fine 

 variety of Boarmia repandata, Larentia coesiata, and Cidaria imma- 

 nata in thousands ; several Coremia propugnata and Tanagra choero- 

 fhyllata. By beating the trees, most of which are birch and alder, 

 we obtained a few larvae, viz : — N. dictoeoides, N. dromedarius and N. 



ziczac, G. ridens. A. menyanthidis, three Drepana % (which died), 



and S. illastraria. On heath and heather we found L. quercus and 



carpini, the latter abundant ; these were full fed by Aug. 15th.
