 British Mn>euni, toifh Descriptions cf new Species. By

V. 



In the following paper the descriptions of several new species 

 of Apidse and Diploptera are publislied, as well as notes oti 

 known species. Most of the new material is from collections 

 recently formed by Mr. G. E. Bryant in Sarawak and 

 Penang and by Mr. E,. E. Turner in Australia. Mr. Turner's 

 fine collections from Australia, the whole of which are now 

 at South Kensington, are well known to all Hymenopterists. 

 A new species of that curious Eumenid genus Macrocalymma 

 is a very interest ijig discovery. 



Mr. Bryant, who spent some nine months in Sarawak, was 

 primarily occu]ned in collecting beetles, but at my request 

 collected such bees and wasps as he encountered in his 

 excursions. The Thrincostoma and Ccelioxys were two captures 

 of especial interest, the former as introducing a second species 

 to a genus recorded in the Oriental Region for the first time 

 last year, and the latter as connecting the two sexes of a 

 species in which sexual dimorphism is very strongly 

 developed.
