ever having hnd, a local habitation in these Islands. If Dr. Leach 

 did really capture it at Tenby it can only be supposed to have been a 

 casual and accidental introduction among alpine plants ; but it is far 

 more probable that the captor was not sufficiently careful in labelling 

 his specimens taken here and on the continent. 



So far as my own judgment goes, there is not a shadow of a shade 

 of evidence that either of these species has ever possessed a right to 

 inclusion in the British Fauna.

NOTES ON ASSEMBLING OF MALES OP CERTAIN MOTHS IN CEYLON. 

 BY E. EKNEST GREEN", F.E.S. 



The following facts in connection with the assembling of the 

 males of certain moths in Ceylon may be of interest to entomologists 

 in other parts of the world. 



Amongst Eupterotidcs I have taken & Fabia, Cram., and undafa, 

 Blanch., in this manner. 



In the family Lasiocampidce the males of Trahala Vishnu, Lef., 

 can be constantly taken by exposure of a freshly-emerged female. 



Heti'Tusia ciiigala, Moore, amongst the Zijgasnidm, is also strongly 

 attractive. 



Nearly all the Lymantridce exhibit the same phenomena. In the 

 case of Lymantria ampla, Walk., my rooms were for several days 

 besieged by male admirers of the particularly unprepossessing-looking 

 female moth. It was noticeable that they continued to present them- 

 selves for several days after she had been impregnated, and even after 

 she had been killed and set. For ten days or a fortnight after the 

 death of the female the males continued to arrive and to flutter round 

 the breeding cage in which she had been confined. Dasi/chira Hors- 

 fieldi, Saund., is another Lymantrid with very strong powers of 

 attraction. 



Though this emanation, whatever it may be, is extraordinarily far 

 reaching, it is unable to penetrate even a thin sheet of writing paper. 

 I kept a female Z>. Horsjieldi for several days, without the advent of 

 a single male, in a glass jar, the mouth of which had been covered 

 with a piece of paper ; but immediately after this paper had been 

 perforated with a few pin holes the males commenced to arrive. 



In all the cases noted above the moths were displayed in the 

 verandah of my bungalow.
