Besides there still exists a small number of caterpillars 

 where the question must remain for the present undecided, 

 because either the possession of the organs in question has not 

 been definitely verified, or opinions in the literature are contra- 

 dictor}'. Of the greater part of the caterpillars mentioned 

 here, nothing more, indeed, is known than that they live with 

 the ants in Symbiosis. Which species of ant comes into ques- 

 tion is, in the large majority of cases unknown. De Niceville 

 only can we thank for extensive information on the subject. 

 Every butterfly collector who collects the Lycaenid caterpil- 

 lars, should therefore not neglect to observe the ants that visit 

 them, to observe the manner of their intercourse with the cat- 

 erpillars, to preserve a number of ants in spirit, and to publish 

 the well-determined names of both ants and caterpillars. It is 

 by no means sufficient to say : " visited by a little yellow ant," 

 or "in company with the common black ant." Generally 

 it is not necessary to seek far for the ants, for the nest is often 

 to be found under the feeding plant. Also the digging out of 

 such nests often offers a proof of the living together of cater- 

 pillars and ants. In a whole series of Argus-caterpillars pupa- 

 tion seems to take place in the nest of their visitors. Perhaps 

 also many species hibernate in the same place. Observations 

 on this point have not yet been published. The question of in 

 how far the shelter ascribed to the ants really exists would 

 be greatly explained by such observations. An especial atten- 

 tion should be devoted to the behavior of the ants towards 

 those butterflies which come out in their nests. No observa- 

 tions exist on the behavior of the species of ants to those cater- 

 pillars which they do not normally visit ; thus the so-called
