intention of examining and making out the species on his return 

 home. When he got home and found out what a rare and curious 

 insect he had found, he was quite surprised, and regretted he had 

 not taken more. 



Is the genus parasitic on the ants or on the myrmecophilous 

 beetles ? 



It is truly significant that both in Europe and in America the 

 genus is found only associated with ants, but as yet we have no 

 authentic information as to the parasitic habits of the species. 

 We trust Mr. Pergande will continue his observations on the 

 species discovered by him and definitely settle the question as to 

 its parasitism. 



All other genera in the Microgasterinas are parasitic only on 

 lepidopterous larvae, although two or three species of Apante- 

 les and Microgaster are recorded as having been bred from 

 rhynchophorous beetles. 



The specimens spoken of above represent three distinct species 

 and may be tabulated as follows :
