species as "A. compressiventris Guerin (=A. siberica Sauss.)." 

 Krombein (personal communication, 1956) has commented upon this 

 synonymy as follows : Ampulex siberica Sauss. is apparently a mis- 

 identification by Saussure of sibirica Fab. Kohl (1893) in his revision 

 of the genus Ampulex considered A. compressiventris Guerin to be 

 the correct name for this common African species and that sibirica, 

 described from Siberia, must be another species. However, Turner 

 (191 2) stated that he had seen Fabricius's type specimen and that it 

 was identical with what had been called compressiventris; he con- 

 sidered the Siberian locality given by Fabricius as an error. Krombein 

 suggested that Williams's use of the combination siberica Sauss. was a 

 lapsus and that the valid name, if Turner is correct, is sibirica Fab. 



Natural hosts. — Cockroaches, West Africa (Perkins in Sharp, 

 1899) : Nesting sites are keyholes. Enters apartments in search of 

 cockroaches. Wasp cocoon protrudes from dead body of cockroach. 



Ampulex sonnerati Kohl 



Synonymy. — "La mouche bleue" of Sonnerat (Kohl, 1893). 



Natural host. — "Kakkerlac," Philippine Islands (Sonnerat, 1776) : 

 Nesting sites are ready-made crevices. The wasp seizes the cockroach 

 by an antenna and stings the host many times in the "abdomen." She 

 drags the cockroach by an antenna to the nest, and, after depositing 

 her egg, plugs the opening with moistened earth. 



Dolichurus bicolor Lepeletier 



Synonymy. — Schulz (1912) considered this to be Dolichurus cornic- 

 uliis. Berland (1925) stated that this is possibly a color variety of D. 

 corniculus. Soyer (1947), from a study of the behavior of the wasps, 

 believed that both D. bicolor and D. haemorrhous are varieties of D. 

 corniculus. Krombein (personal communication, 1956) stated that D. 

 corniculus and D. bicolor differ in characters other than color alone 

 and that D. bicolor is considered a valid species today. 



Natural host. — Cockroach, France (Benoist, 1927) : The wasp was 

 observed closing the entrance to its burrow. Its egg was attached to 

 the coxa of the midleg of the cockroach, 



Maneval (1932) stated that D. bicolor is found at the edge of dry 

 woods along with D. corniculus and that the wasp will also accept the 

 prey of D. corniculus if presented to it. 



Dolichurus corniculus (Spinola) 



Synonymy. — Dolichurus haemorrhous Costa [Schulz, 1912]. Ber- 

 land (1925) listed D. haemorrhous separately but stated that it is per- 

 haps a color variety of D. corniculus.
