NOTES AND OBSERVATIONS. 231 



lineolata Lep. were observed swarming in the sun over beds of 

 Ajaga reptans. The great majority were males, but couples 

 were observed in copulation. Two females and eight males were 

 captured, placed under a glass jar covering a patch of planted 

 A. reptans, and observed for a week. Copulation occurred at 

 intervals, and lasted for at least some minutes. No eggs were 

 laid — I was unaware then that the species lays on oak— but this 

 did not seem to affect the mating process. Polyandry was not 

 observed, but I think it very probable. 



Pristiphora ruficornis. — 'ln one experiment a single male and 

 female kept in a large glass jar with a hawthorn twig for four days, 

 and given opportunity to drinkand feed, were never observed to mate. 



Amauronematus vittatus. — Mating was not observed, during 

 observation lasting one hour, of flies in a small glass vessel which 

 capped a small alder twig.

NOTES AND OBSERVATIONS. 



New Names for Old. — In February, 1910, I published in Trans. 

 Linn. Soc. (2nd ser., Zool.), vol. xiii, pp. 301-305, the description of 

 a Pyralid moth from Praslin, Seychelles, under the name Nacoleia 

 maculalis Eletcher. As I now find that my name is an absolute 

 homonym of Nacoleia maculalis South (Trans. Ent. Soc, 1901, 

 p. 462, t. 14, f. 7), described from Central and Western China, the 

 Seychelles species may be renamed as insulicola nom. nov. The 

 generic name Nacoleia Wlk., 1859, is ante-dated by Lamprosema 

 Hb., Verz., p. 361, 1826. 



The generic name Arbela Moore (P.Z.S., 1879, p. 411), in Lepidop- 

 tera, is a homonym of the Eeduviid genus Arbela Stal (Hem. Afr., iii, 

 pp. 38-42, 1865). In vol. i on moths in the Fauna of British India, 

 p. 314, 1892, Sir George Hampson founded the family Arbelidse on 

 Arbela Mo., but this family name has since been changed to Teragridse, 

 founded on Teragra Wlk., the first described genus contained in it. The 

 African genus Teragra is, I believe, not identical with the Indian genus 

 Arbela Mo., which is now renamed Indarbcla nom. nov., type tetraonis 

 Moore. — T. Bainbrigge Fletcher; Pusa, India, July 31st, 1922. 



Notes from the Alton District, Hants (Lep.). — On June H>th 

 there emerged from a mixed lot of pupffl Hydrelia uncula. As I had 

 no marsh larvae or pupa?, the only explanation possible is the follow- 

 ing : The preceding autumn, passing the swamp near Oakhangor,
