876 Hymenoptera in America North of Mexico 



"the most singular looking and wonderfully shaped chalcids known, the structure of the thorax, 

 and particularly of the scutellum, being most wonderfully and curiously modified and developed; 

 this development, in connection with the brilliant colors of its members, makes the group the 

 most striking and attractive of any in the superfamily." However, disregarding these adaptive 

 differences, but considering the fundamental structure of the thorax, it is clear that the 

 eucharitids are descended from the same ancestral stem that produced the present-day 

 pteromalids.
