NEW SPECIES OF SPIDER WASPS, GENUS AUPLOPUS, FROM 

 THE AMERICAS SOUTH OF THE UNITED STATES 

 (HYMENOPTERA : PSAMMOCHARIDAE) 



By R. R. Dreisbach 



Introduction 



This paper is divided into two parts, the first covering Mexico, 

 Central America, and the Caribbean region, and the second part 

 South America. Keys for the species of each region follow this 

 introduction. 



Cameron^ lists 28 Mexican and Central American species for this 

 group under the genus Pseudagenia Kohl. Since this paper was 

 published at a time when the species were placed in only a few 

 genera, it is impossible to laiow from his paper which species belong 

 in the genus Auplopus Spmola (which replaces Pseudagenia Kohl) . 



This problem was solved for the writer by Dr. H. K. Townes in 

 his trip to the British Museum to study the types of Ichneumonidae. 

 He checked Cameron's types and placed them in the correct genus 

 according to present-day knowledge. He was well qualified for this 

 as he had just recently published on this group for the North 

 American fauna. His investigation reduced the 28 species listed by 

 Cameron to 13 species for the genus Auplopus Spinola. This paper
