Epeolus bifasciatus (Proc. Entom. Soc. Philad. iii. p. 38, 

 1864). More recently Jbrgensen used the name yet again 

 for a species from Argentina, and his species has been 

 renamed E. potrerillensis by Jensen Haarup.

A careful examination of the type specimens of these 

 insects has failed to reveal any satisfactory structural cha- 

 racter for their separation. The ferruginous markings on 

 the mesonotum of N. ccanthidica, though absent in the type 

 of N. japonica, are present in another specimen from Hiogo, 

 and such colour-markings are often variable. Alfken 

 asserted some time ago that the two species were identical ; 

 but Professor Cockerell believed them to be distinct (Trans. 

 Amer. Ent. Soc. xxxi. p. 364, 1905). 



Bingham (' Fauna Brit. India,' i. p. 465) considers N.sub- 

 petiolata, Sra. (1879), from Bombay, to be synonymous with 

 the same author's N. adusta (1875). It would seem that 

 the variety he mentions (/. c. p. 46(5) is Smith's N. subpetiulata. 

 There can, however, be little doubt they are distinct species. 

 N. adusta (type in G. 11. J. Rothney Coll.) has the "scutellum, 

 postscutcllum, the tubercles, and collar yellow," according 

 to the original description, and there is no mention of the 

 longitudinal mesouotal groove to which Bingham refers in 

 his description of the variety (/. c). N. subpetiolata (type 

 in B. M.) has the thorax " ferruginous, with a black longi- 

 tudinal groove on the mesothorax," and Smith would 

 certainly have mentioned the groove if present in N. adusta.
