104 THE ENTOMOLOGIST. 



of British Lepidoptera and had acquired a considerable knowledge of 

 the species occurring in the Brighton district and surrounding 

 country. From early youth the son took an active interest in Nature 

 study with a special leaning to entomology. He soon became as 

 expert as his father in field-work, and thus to a large extent was 

 prepared for undertaking the more arduous labours he afterwards 

 accomplished. 



In the year 1880 young McArthur was engaged by Mr. Meek to 

 collect lepidoptera in the Shetland Isles. This trip was so successful 

 that in the following year he again visited the Shetlands and then 

 added thirteen species to the list of fifty-three he had previously 

 obtained. In 1883 he once more journeyed to the Shetlands, but on 

 this occasion Unst, the most northern isle of the group, was the 

 scene of his operations. Among the half-dozen additional species he 

 secured w'as Grymodes [Hadena) exults. The Outer Hebrides next 

 attracted his attention, and in 1887 he spent the entomological 

 season of that year in the Isle of Lewis. As he added some seventy 

 odd species to the list of lepidoptera known to occur in that island, 

 this venture seems to have been highly successful, although he had a 

 severe illness whilst there. 



In 1888 and 1889 he collected in Kashmir for the late John Henry 

 Leech, Esq. Travelling through Lahaul and Ladak up to the Kara- 

 koram, he probably worked a good deal of country that had never 

 been visited by an entomologist before. The winter of 1888-89 he 

 spent in the Malay Peninsula. The difficulties attending him during 

 the Kashmir journeys were great, but the fact that he, in spite of all 

 obstacles and endless trouble with natives, coolies and others, attained 

 his object, shows him to have been a man resolute in the perform- 

 ance of whatever he undertook. A large number of insects, chiefly 

 moths, were captured, and many specimens of previously described, 

 but rare, species were obtained. 



In 1892 he visited the Shetlands for the fourth time, and in the 

 following year he had a season in Co. Cork, Ireland. Collecting in 

 Orkney during the season of 1895 he added seventeen species to the 

 list of Orkney lepidoptera; and four months spent in the Isle of Lewis, 

 in the year 1901, increased the number of species of lepidoptera known 

 to occur in that island by seventeen species also. His last entomolo- 

 gical expedition (1908) was to Aviemore, and here the initial stage 

 of his fatal illness seems to have attacked him, but he would not give 

 in, and even made an expedition to HaiTis in June, where, however, he 

 was unable to obtain access to suitable collecting ground. On his 

 way back to Aviemore he spent a few days in a reputed locality for 

 ZygcBna achillece, but as he could not obtain this species, or find a 

 shelter for himself, he had to leave the inhospitable district. After 

 his return to London he appeared to be in his usual health for a 

 time, but subsequently he broke down and in May, 1909, he went 

 into hospital, as it was found that he was suffering from cancer. 



We also regret to announce the decease, at an advanced age, of 

 Albert Piffard, Esq., F.E.S., &c.,of Felden, Boxmoor, Herts.
