Tribe CRYPTINI 



Just as the Cryptinae is the largest of ichneumonid subfamilies, the Cryptini is the largest 

 tribe in the subfamily. Although the greatest numbers of genera and species of Cryptini occur in 

 the tropics, the tribe is well represented in North America. Townes (1970) implies that the spe- 

 cies of Cryptini search for their hosts primarily among foliage rather than in the soil or ground 

 litter and differ from the species of Aptesini and Hemitelini in this respect as well as in having 

 larger average size. 



Townes (1970) divided the Cryptini (=Mesostenini) into subtribes which are partly for con- 

 venience and partly to show what he believed to be some of the natural groupings of genera. In 

 the hope that this classification is actually an improvement over that of Townes and Townes 

 (1962), the former is adopted here with little modification.
