Osniia rubripes is very near 0. rufohirta, Lep., and be- 

 longs to tlie subgenus Acanthosmia, Thorns. 



Osmia laboriosa, Stn,, from Yarkand, somewhat resembles 

 O. rufigastra, Lep., from Algeria, but differs in having the 

 scape, mandibles, and anterior margin of the clypeus reddish, 

 whereas in O. rufigastra all these parts are black. Cockerell 

 (Trans. Araer. Ent. Soc. xxxi. p. 333, 1905) writes a note 

 on tlie species. The black markings on the abdomen give 

 the insect a very distinct appearance. The North American 

 species are satisfactorily dealt with by Cockerell. 



Osmia jucunda, Smith. 



Osmia jucrmda, Smith, Catal. Hymen. Brit. Mus. i. p. 139. no. 36 



(185.3). $. 

 Osmia vidua, Gerst. Stettin, eut. Zeit. xxx. p. 345. no. 9 (1869). 



Smithes type of 0. jucunda from Albania agrees perfectly 

 Avith specimens determined by Friesein the Edward Saunders 

 collection. Gerstaecker described his species from Sicily. 



Osmia apicata^ Smith. 



Osmia apicata, Smitli, Catal. Hymen. Brit. Mus. i. p. 140. no. 37 



(1853). 2. 

 Osmia macroylossa, Gerst. Stettin, ent. Zeit. xxx. p. 349. no. 12 (1869). 



Smithes type of 0. apicata agrees perfectly with specimens 

 in the Edward Saunders collection determined as O. macro- 

 glossa by Friese, and with a specimen from Corfu determined 

 by Schmiedeknecht. In his 'Apidae Europsese,^ Schmiede- 

 knecht suggests that they are co-specific, but does not 

 synonymise them, being unable to determine 0. apicata 

 satisfactorily from the description.
