XI, D, 5 Cockerell: Ceratinid Bees 303 



differs from the typical extra-Philippine insect, from the Asiatic 

 mainland, by having the male scape entirely black. It may, 

 therefore, take the name A. cupulifera hakeri var. nov. ; type 

 locality, Los Banos (Baker 3655) . 



AUodape palavanica sp. nov. 



Female, 6.5 millimeters long; like A. marginata, but clypeus 

 practically all yellow and narrow lateral face marks developed; 

 hair of hind legs whitish as in marginata. Perhaps only a 

 variety, but in view of the locality, probably a distinct species. 



Palawan, Puerto Princesa {Baker 5009). 



Allodape reversa sp. nov. 



Male, 4 millimeters long, or slightly more; like A. cupulifera, 

 but clypeus with the light area broadened below, covering the 

 whole apical part ; the vertical band very broad, but not expanded 

 above; no lateral face marks; tarsi ferruginous. The scape is 

 all black. 



Palawan, Puerto Princesa (Baker 5011). 



The accompanying female, from the same place (Baker 5010), 

 does not materially differ from A. cupulifera. This may be no 

 more than a variety of A. cupulifera. The whole group of Al- 

 lodape, described above, is very compact and is uniform in the 

 principal characters. Differences in the venation do not appear 

 to be constant for particular species and races. In Luzon, 

 Palawan, and Mindanao, as on the Asiatic mainland, large and 

 small forms coexist. It is probable that each island, when well 

 separated from the others or of any considerable size, has a 

 race or species of its own ; but if this is true, it may yet be found 

 that the characters of these races are mainly or wholly confined 

 (so far as external appearances go) to one sex, or are such 

 as occur in occasional varieties in the other races. The further 

 study of this problem should be in the hands of a resident 

 naturalist. 



Allodape jucunda Smith, which has been erroneously listed 

 from the Philippine Islands, is a South African species. 



Genus CERATINA Latreille
