Whki:i.i:ij finds that umler natural eoiiditinns the food of Lepto- 

 i:^i/ns (loH^iitii consists very largely, if not cxc lusively, of the isopods 

 Onisius antl Antuidillidiitm. This is the only ant known to show so 

 marked a prefereiK e for crustacean f(Mid ; the other members of the 

 same genus a|)i)ear to '(ck^kX for the most part upon termites. 



The males of /,. t/oih^afa are winged, but the females are apter- 

 ous, in appearance nmch resembling the workers. How the fertiliza- 

 tion of the females takes place is thus an interesting (piestion. Of 

 course a nuptial llight is precluded l)y the wingless condition of tlie 

 females, and \Viii:i:i kk < onsiders it im|)robable tiiat the males of one 

 nest find their way into other nests and so fertilize the females there. 

 If the females are fertilized by the males of the same colony, the author 

 j)i>inls out that this would be a mo.^t tlagrant case of ind)reeding, so it 

 seems reasonabk' to snppo.se that the females issue from the nest at 

 night as pedi'strians and in this way meet the males of other nests, as 

 the latter also go t'oith at night. The males are said to be "high- 

 ly hcli()ta( ti< ." L. I. coi.K.

.\ number of rather desuitor\- experiments were made upon the 

 marciiing colunmsof the recently hatched cateri)illars of I/ciiii/nca main. 

 it was found that w hen the leading caterpillar of a line was removed 

 the pr()( ession was stopped and the larv;e gathered into a bunch. In 

 nine out of twenty-one experiments the original leader when returned 

 again took the lead and the line followed ; in the other eleven cases 

 a new leader took the place of the one removi'd. No general conclu- 

 sions are drawn. i,. .1. coi.E.
