New Genera of Bees* 



By T. D. a. Cockerell, 



CLADOGERAPIS n. g. 



Male with joints of flagellum with processes directed for- 

 wards, on upper side, and large branches bearing little filament- 

 like processes, often forked, on under side ; area of metathorax 

 smooth and shining, with an obscure transverse ridge ; basal 

 nervure meeting transverse medial ; first recurrent nervure 

 joining middle of second submaginal cell ; second recurrent 

 nervure entering third submaginal cell a short distance from 

 its end. Type Cladocerapis dadocerus {Lamprocolletes clada- 

 cerus, Smith, 1862). Australia. Type of species examined 

 in British Museum. 



TMCHOCERAPIS n. g. 



Male with antennal joints 10 to 12 reduced to mere threads, 

 ciliate on one side ; joint 13 an oval flat dark disc ; wings very 

 hairy ; malar space large, in the type species black, contrast- 

 ing with the adjacent yellow mandible. 



Type Trichocerapis mirabilis {Tetraloiiia mirabilis, Smith, 

 1865) Brazil. Type of species examined in British Museum. 

 The structure of the antennae reminds one of Thaumatosoma. 



HYPANTHIDIUM n. g. 



Second recurrent nervure passing well beyond second sub- 

 marginal cell, as in Dianthidium, but no pulvillus ; apex of 

 male abdomen bilobed or entire. Type Hypanthtdiutn flavo- 

 marginahwi {Anthidium Jlavornargmattim , Smith, 1879). 

 Brazil. Also includes H. elegantuhim (Smith), H . Jiavopictum 

 (Smith), and H. guttatum (I,atr), all hitherto referred to 

 Anthiditim. I strongly suspect that flavopidum is the male 

 of elegantiilum. 



HETERANTHIOIUM n. g. 



Second recurrent nervure meeting second transverse cubital, 

 as in Anthidiiun, s. str., but a large pulvillus on feet. End 

 of male abdomen pointed. Type Heteranthidium dorsale 

 {Anthidium dorsale, Lep. Sm.). Georgia.
