414 THE ENTOMOLOGIST. 



England. — Mr. Norman H. Joy, a remarkable specimen of Oxytehis 

 taken at Tresco, Scilly Isles, April, 1908. In many respects it is 

 quite intermediate in character between 0. sculptus and 0. laqueatus, 

 Marsh. It is probably a species new to science, but may possibly be 

 a hybrid of these two species. He also showed Liodes stenocoryphe, 

 Joy, male, taken by Mr. W. E. Sharp, at Forres, in 1910, as well as its 

 near allies for comparison, viz. L. picea, 111., taken by Mr. Tomlin 

 and Mr. Joy at Dalwhinnie, Inverness-shire, in September, when the 

 larva was also found feeding on a small underground fungus ; 

 L. ditbia, King, and its various varieties, and L. algirica, Eye, almost 

 certainly only another variety of this species. — Mr. W. C. Crawley, a 

 mixed colony of Lasius umbratus and L. niger. This colony consists 

 of a female L. wnbratus, which was accepted in 1908 by a queenless 

 colony of L. niger. During 1909 and 1910 only niger workers 

 came to maturity in the nest ; those, therefore, that hatched in 

 1910 must have been from parthenogenetic eggs laid by the niger 

 workers. Over a dozen of these latter were dissected, and 

 found to contain no receptaculum seminis. — Mr. Donisthorpe com- 

 mented on the interest of Mr. Crawley's experience, remarking that 

 while it had formerly been supposed that parthenogenetically laid ova 

 produced only males, Mr. Crawley had shown, and proved by dis- 

 section, that workers were capable of parthenogenetically pro- 

 ducing workers. The President observed that parthenogenesis 

 was not unusual in sawflies, and mentioned that in Crcesus varus, 

 which had been founded on a male specimen, the original specimen 

 was the only male known. Dr. M. Burr remarked that the common 

 " stick insect " is largely parthenogenetic, and has been bred par- 

 thenogenetically for more than twelve consecutive generations. — Mr. 

 E. A. Cockayne exhibited a melanic specimen of Lithosia deplana, 

 male, taken in Surrey last July. — Mr. J. Piatt Barrett, some species 

 of Sicilian butterflies taken this year, in contrast with corresponding 

 British species, viz. Euchloe cairlamines and E. damone, Gonep- 

 teryx rhamni, and G. cleopatra, Hipparchia semele, and var. 

 algirica. Small southern forms were also exhibited of E. carda- 

 mines and Leptosia sinapis. — Dr. Chapman, living larvae of Albulina 

 piheretes, and a living imago of Latiorina orbitulus ; and observed 

 that his former suggestion that A. pheretes had probably a larva 

 without a honey gland was incorrect. The larva of A. pheretes 

 possesses a honey gland and fans. Owing probably to the warm 

 weather during August and September, three of the larvse reached 

 the last instar, and he was therefore able to exhibit the larva in the 

 third, fourth, and fifth (or last) instars. L. orbitulus also afforded 

 " forward " larvae this season, and the Hving butterfly of this 

 autumnal emergence, which was exhibited, left the pupa on October 

 2nd ; but Vacciniina optilete, without exception, stopped at the third 

 or hybernating instar. — Mr. J. H. Durrant, two new British species 

 of Blmjacionia, Hb. {^Betinia, Gn. ; Evetria Hb. Meyr.), viz. Ehy- 

 acionia purdcyi, sp. n., taken among Scots firs at Folkestone at the 

 end of July, 1911, by Mr. W. Purdey, a very distinct species inter- 

 mediate between sylvestrana, Crt. and duplana, Hb. ; and B. logcea, 

 sp. n., from Forres, Scotland (W. Salvage and H. McArthur), closely 

 allied to duplana, Hb. and posticana, Ztst. The type male of this new
