Exhibitions. 



A new form of Morpho eugenia. — Mr. Arthur Dicksee 

 exhibited three specimens of a new race of Morpho eugenia 

 from Colombia, from which it was hitherto unknown, together 

 witli two Morpho eugenia from French Guiana, and one 

 Morpho adonis from French Guiana, and another from the 

 Lower Amazons, for comparison. 



He pointed out that the shape was half-way between the 

 rounded form of eugenia and the pointed form of adonis, and 

 that the colour approached more nearly to the colour of 

 adonis, whereas the white costal markings approached more 

 nearly to M. eugenia. He gave it the name of M<>r/>ht> 

 eugenia, form damocles. The locality is Villavicencio, Colombia, 

 and the dates are May and .lime 1918.

 of home-bred L. m arion, together with their pupa cases. 



He pointed out. that the full-fed larva seldom, if ever, 

 attempted to crawl faraway from the ants in order to pupate. 

 Larvae which he had kept both in the nests of .1/. scabrinodis 

 and .1/. laevinodis generally fed in chambers deep down in 

 the nest where the small ant larvae in their last instar were 

 cared for by the workers. When the arion larva was full fed 

 he generally remained where he was among the brood, slowly 

 changing colour from a line ochreous hue to a dead grey 

 white Six or seven days migh.1 elapse before the larval skin 

 was cast. The ants were running over their guest all the 

 time but never attacked him. even when the fresh pupa was
