Hab. Rosebank Experiment Station, S. Africa, on flowers, 

 Dec. 9, 1909, 4 ? (C. K. Brain). 



Closely related to T. mhmticornis, Friese, but smaller in 

 every way. Also allied apparently to T. kobroivi, Friese, 

 but without any pale band on clypeus, which I infer to exist 

 in kobroivi from Friese's comparison with T. dentata. 

 T. riipicola does not especially resemble T. dentata, and it 

 would not occur to me to make comparison Avith that species. 

 Friese says that the mandibles of kobroivi are reddish yellow 

 apically, which is not true of rupicola. The flagellum of 

 rupicola is dark reddish above (black in kobroivi) and paler 

 but dull red beneath, the third joint is a little shorter than 

 the next two together. The tarsi of kobroivi are red, whereas 

 only the small joints are red in rupicola. 



The maxillary palpi of T. rupicola are short, with the two 

 apical joints small, sometimes looking like one. 



Tefralonia dilecta (Cresson). 



Blooniington, Indiana, May 16, 1 ^ [Max Ellis). 

 This species ranges unchanged west to Colorado. 



Tetralonia robertsoni, sp. n. 



$ . — Length about or nearly 15 mm. 



Black, robust ; clypeus entirely black, strongly punctured ; 

 third antennal joint a very little longer than the next two 

 together ; hair of head, thorax, and basal segment of 

 abdomen very pale ochreous ; hair of rest of abdomen black, 

 reddish black at sides of apex ; anterior femora with whitish 

 hair, middle femora with a patch of reddish hair bancath at
