The Zoologist — February, 1866. Ill 



Exhibitions, SfC. 



Mr. S. Stevens exhibited four large cases of Lepidoptera and Coleoptera from the 

 Himalayas, containing; numerous rare species, and many of the Lepidoptera having 

 been bred from the larvse. 



Mr. Bates gave an account of Mr. Bartlett's explorations in the Amazons country; 

 he had gone up the Amazons River as far as Nanta, and had thence followed the 

 course of the Ucavli until he reached the eastern slopes of the Cordilleras : a collection 

 of objects of Natural History, including several thousand insects, the result of four 

 months' labour, had been despatched, and might shortly be expected in England. 

 Whilst speaking of the Amazons, Mr. Bates desired to mention that the local 

 authorities at Para, which was merely the chief town of a province of Brazil, had 

 recently voted £600 towards the expenses of scientific researches undertaken by 

 Agassiz. 



Prof. Westwood read extracts from a letter from M. Snellen van Vollenhoven, 

 recounting some of his entomological experiences during the past season. 



A conversation ensued respecting the female Lepidoptera which occur in autumn 

 with undeveloped ovaries. Mr. J. Jenner Weir inquired whether such females, after 

 hybernation, were found to have developed ovaries in the spring? It might be that 

 early hybernation was an aid to the development of the ovaries. Prof. Westwood 

 thought it probable that the ovaries were developed during the winter; the difficulty 

 was to say when the impregnation took place; this, in the case of wasps, must be in 

 the autumn, since the males did not survive the winter. Mr. M'Lachlan observed 

 that nearly all the hybernated specimens of Vanessa were females; but he had himself 

 taken Cerastis Vaccinii and C spadicea respectively in copuld on sallow-blossoms in 

 the spring. 



The following are descriptions of the three new exotic Longicorn beetles exhibited 

 by Prof. Westwood at the previous Meeting: —
