SOME MYEINIECOPHILOUS INSECTS FROM HAYTI. ^ 



By William M. Mann, 

 Bussey Institution, Harvard University. 



The insects here noted were collected in Hayti during the winter 

 of 1912-13. Few myrmecophilous insects have been recorded from 

 the West Indies, though no doubt many occur there as the 

 ant fauna is varied and abundant and contains many ancient 

 types. Of these Aphamogaster relicta Wheeler & Mann is the 

 predominant Myrmicine ant on the island, and this species was 

 found to harbor several interesting inquilines. 



In addition to the species recorded in these notes several others 

 of possibly myrmecophilous habits were taken. I hope to list 

 these after further study. 



Mr. A. B. Wolcott, of the Field Museum at Chicago, has very 

 kindly drawn the accompanying figures. 



The types of the new species have been deposited in the Museum 

 of Comparative Zoology at Cambridge.
