unique. He held that Ascoschongastia should be restricted to 

 species with this character, and he expanded Euschongastia to 

 include all other species formerly placed in Ascoschongastia. 

 Fuller (1948) followed Wharton's concept and placed in Euschon- 

 gastia a number of old species, including E. trouessarti. In 1950 

 Ewing split off the monotypic genus Boshellia (type species 

 Neoschongastia hirsuta Boshell and Kerr, 1942). Recently, Fuller 

 (1952), along with a list of the known species, gave a more com- 

 plete diagnosis of the genus, v/hich is accepted for this paper. 



Distribution : The genus Euschongastia is widely distributed 

 over the world. It has been found wherever collections have been 

 made. In Ewing's original description only the genotype, E. 

 americana, was included. Fuller (1948, 1952) has assembled most 

 of the known species which were described originally under other 

 generic names. Also, he has synonomized certain species with 

 E. indica. Brennan (1947, 1948) described new species from 

 North America. Recent Ascoschongastia species of Lawrence 

 (1949) from Africa are placed here in Euschongastia. Boshellia 

 Ewing, 1950, is here considered a synonym of Euschongastia. If 

 Euschongastia later is split into subgenera, Boshellia will prob- 

 ably be valid at that level. All species are brought together in the 

 following list, which summarizes by geographic regions the 

 species of Euschongastia described at the present time :
