THE ENTOMOLOGIST. 



B. Eyes quite flat. Ocelli very small. Basal 

 joint of the antennne much longer than 

 the first joint of the flagellum. Wings 

 rudimentary. - - . - MrBMECOMORPiiA. 



Myrmecomorplia corresponds with Pedinomraa, Foerst., 

 and is an earlier name. I have found the species on which 

 it is founded under a stone near Chepstow.

 dominal segments unequally long. - - Isobrachium:. 



Foerster changes Scleroderma to Sclerochroa, because the 

 former name was previously used in Botany. Ateleopterus is 

 founded on Bethylus ateleopterus, Perisemus on B. triareo- 

 latus, Goniozus on B. clavipennis and on B. fuscipennis, and 

 Isobrachium on B. dichotomus: all these species were pre- 

 viously described by him, and B. dichotomus is a synonym 

 of B. fuscicornis, Nees (male), and of B. nigricornis, Nees 

 (female). The materials of this family do not agree well 

 together; a connection may be traced between them and the 

 Chrysididse.
