curiously engraven in niezzo-tinto, printed upon a large sheet of paper. 

 Sold by Pierce Tempest at the ' Eagle and Child ' in the Strand, over against 

 Somerset House Water Gate." This engraving must now he of some 

 rarity, and we should be curious to learn whether the portrait is sufficiently 

 faithful to enable an identification of the particular species of Asiatic 

 Rhinoceros which was first imported to this country. 



SCIENTIFIC SOCIETIES. 



Linnean Society of London. 



February 15, 1883.— Sir John Lubbock, Bart., M.P., F.R.S., President, 

 in the chair. 



Mr. J. Jenner Weir exhibited a perfect hermaphrodite butterfly {Lycmna 

 icarus), and a blue male and brown female of the same species for com- 

 parison. The hermaphrodite in question possessed two spotless blue wings 

 on the left and two spotted brown wings on the right, thus being inter- 

 mediate in colour between the two sexes. 



Dr. W. C. Ondaatje exhibited a collection of thirty species of Ceylon 

 corals, of which twenty were of a stony character. The series agree in the 

 main with those of the Indian fauna ; four are new species, namely, two of 

 Cceloria, one of Pavonia, and one Alcyonium, the two latter, however, 

 showing most affinity to forms met with in islands of the Pacific Ocean. 



A paper was read " On the ' Manna,' or Lerp Iusect, of South Australia," 

 by J. G. Otto Tepper. This contains observations on the insect in question, 

 and on the peculiar saccharine substance derived from it and deposited on 

 various species of Eucalypt trees. 



March 1, 1883.— Sir John Lubbock, Bart, M.P., F.R.S., President, 

 in the chair. 



The followiug gentlemen were elected Fellows of the Society : — W. B. 

 Barrett, L. J. K. Brace, J. B. Bridgman, W. O. Chambers, W. E. Clarke, 

 W. Godden, F. H. H. Guillemard, J. C. Havers, T. M. Hocken, C. H. 

 Middleton Wake, J. C. Stirling, and the Rev. P. W. Wyatt. 



Mr. W. T. Thistleton Dyer called attention to, and made remarks on, 

 the dried leaves and rind of the fruit of oranges from the Bahamas partially 

 destroyed by Mytilaspis citricola, Packard. 



Mr. A. W. Bennett read a paper " On the constancy of Insects in their 

 visits to Flowers." He stated, as a summary, that the different classes of 

 insects show very great difference in this respect. Butterflies exhibit but 

 little constancy, except in a few instances ; but they would appear to be 

 guided to a certain extent by a preference for particular colours. The
