(13) 14. Scapes longer. Pubescence very pale, golden or silvery 



Grandidieri, Forel, race mendax, Emery. 

 (12) 15. No glabrous line present on the abdomen in the 2j.. Dorsum of the 



epinotum triangular, much narrowed at the base ; antennae and legs 



red ..... Grandidieri, var. Rollei, Forel. 

 (11) 16. Abdomen shining or subopaque,in greater part finely reticulate-coriaceous. 



Pubescence generally short and more sparsely distributed. 

 (22) 17. The two faces of the epinotum meet in a distinct angle, the apex of which 



may sometimes be rounded ; no glabrous median line on the abdomen. 



(19) 18. The erect pilosity on the abdomen as fine as the pubescence 



Olivieri, Forel, var. tenuipilis, Em. 

 (18) 19. The erect pilosity coarser than the pubescence. 



(21) 20. More robust. Edge of scale rounded ; legs black ; the pubescence slightly 

 yellowish .... Olivieri, var. delagoensis, Forel. 



(20) 21. Slender ; edge of scale more trenchant ; legs brown ; pubescence white 



Olivieri, race tauricollis, Forel. 



(17) 22. The two faces of the epinotum meet in an arc, subangularly only in the 



largest 2j. 2J.- A fairly distinct median glabrous line on the abdomen, 



which is very shining . . . Olivieri, race infelix, Forel. 



Dr. Santschi has transposed to C. Olivieri several of the races and 

 varieties which were named for me by Dr. Forel as belonging to 

 C. foraminosus, and has also made some other minor alterations in 

 the classification. These will be made apparent in the synonymy 

 under the title of each species.

2J., 7-2-9 mm. Head, thorax and legs dark brick-red (burnt sienna), 

 tarsi and petiole brownish red, abdomen black. Head and thorax 

 subopaque, the legs and petiole slightly, the abdomen very shining. 

 Head and thorax finely reticulate-punctate, the larger superimposed 

 punctures are seen under a high magnification to consist of three 

 contiguous round pits. They are almost obsolete on the clypeus, and 

 become shallower towards the back of the head. The epinotum 

 is more reticulate-rugulose than reticulate-punctate. Scale feebly 

 rugulose, the abdomen transversely and finely so. On the body the
