438 THE ZOOLOGIST. 



Mr. J. J. Walker exhibited the following species of Halobates, viz.: — 

 H. sericeus, Eseh., from the Pacific; H. sobrinns, B. White, from Marquesas 

 Islands; H. wullerstorffi, Esch., from Marquesas Islands; H. princeps, 

 White, from the China Sea; and a female of H. wullerstorffi, with ova attached. 



Mr. W. H. B. Fletcher showed a variable series of seventy-five Cyma- 

 tophora or, bred in 1893 from larva3 from Sutherland, a series of about forty 

 C. ocularis bred-in from stock from Oundle. Also a series of thirty-three 

 moths, all females, supposed to be hybrids between C. ocularis male and 

 G. or female, from the above stock in each case, bred as a second brood in 

 August and September, 1893. He stated that he placed the reputed 

 parents in a muslin sleeve on a branch of Populus nigra, and did not open 

 the sleeve until the resulting larvae required fresh food. To the best of his 

 belief the female parent had no chance of pairing with a male of her own 

 species. The supposed hybrids resembled the female parent, except that 

 both orbicular and reniform stigmata were very conspicuous, being pure 

 white filled up slightly with black, whereas in C. or they are usually 

 inconspicuous and the orbicular are sometimes wanting. None of the 

 C. or bred had the stigmata developed so fully as had the hybrids, which 

 were most uniform in this respect. 



Mr. F. J. Hanbury exhibited a specimen of Leucania vitellina, taken 

 at Brockenhurst on August 24th, 1893, by Mrs. Hanbury, and another 

 taken by himself at Freshwater, Isle of Wight, on September 7th; also 

 an extraordinary Gonepteryx rhamni, showing red blotches at the tips of 

 the fore wings, taken by a gardener at Walthamstow, Essex.
