FURTHER NOTES ON THE MA.CRO-LEPIDOPTERA OF 

 THE SHETLAND ISLES. 



By J. Jenner Weir, F.L.S., F.Z.S. 



In the 'Entomologist' last year (Entom. xiii. pp. 249 — 251 

 and 289 — 291) I gave some account of the Macro-lepidoptera of 

 the Shetland Isles, which had been obtained by a collector in the 

 employ of Mr. Meek. Emboldened by the success which had 

 attended Mr. Meek's laudable enterprise, Mr. M' Arthur, the 

 collector in question, has visited the islands this year, and by 

 prolonging his stay to a somewhat later period has extended our 

 knowledge of their lepidopterous fauna. 



Mr. M'Arthur has added thirteen species to the list given by 

 me last year, viz. : — 



Pyrameis Atalanta. Hadena dentina, 



Hydroecia micacea. Plusia gamma. 



Apamea basilinea. Emmelesia hlandiata. 



Miana fasciuncida. Gidaria inimanata. 



Celcena Haworthii. Cidaria testata. 



Caradrina cuhicularis. Garsia imbutata. 

 Noctua C-nigrmn. 



By these additions the total number of Macro-lepidoptera 

 observed in the Shetland Isles has been increased to thirty-eight. 



The period during which the collection was made extended 

 from the second week in May until the middle of September. 

 The season was one of the worst known by the inhabitants, being 

 both very wet and cold ; so that Mr. M'Arthur was obliged to 

 wear an overcoat during the whole of the summer ; the prevailing 

 winds were north-west and south-west. 



Of the thirteen new species taken but few present any 

 difference in colour from the ordinary Scottish or English type, 

 and, beyond including their names in the list of captures, call 

 for no further remark ; but, on the other hand, some present 

 differences of colour from the normal type such as to render 

 them worthy of notice. 



Hydroecia micacea. — Some of the specimens taken are of a 

 darker and richer red than any I have previously seen, but 

 others approach more nearly to the normal colour.
