SaiitVs species appears as P. enxius in Dalla Torre, ' Cata- 

 logus Hymenopterum/ vol. ix. Vespidse, p. 163. The type 

 of P. enxuy bears the label in his handwriting, the specific 

 name being the vernacular term for the species in South 

 America {vide Trans. Ent. Soc. Lond. (3) i. 6, p. 504). 



PuJybia bifasciata, Sauss. 



Polyhia bifasciata, Sauss. £tud. fam. Vesp. ii. p. 172. no. 7 (1853). 

 Foli/bia quadricincta, Sau3S. Etud. fam. Vesp. ii. p. 173. no. 8 (1853). 



A specimen of P. bifasciata determined by Ducke is 

 certainly identical with P. quadricincta, Sm., with the type 

 of which it has been compared. Ducke has doubtless seen 

 the type of P. bifasciata in the Paris Museum. 



Polybia (Parapolybia) sumatrensis, Sauss. 



Polyhia {Parapolybia') sumatrensis, Sauss. Rev. et Mag. Zool. (2) vii. 



p. 374 (1855). 

 Icaria sulciscutis, Cam. Proc. Zool. Soc. Lond. vol. ii. p. 30 (1901). 

 Icaria rubrisctdis, Cam. MS. 



Dr. Schulz, in ' Spolia Hymenoptei'ologica/ places Icaria 

 sulciscutis, Cam., described from Singapore, in the right 

 genus. 



There can be no doubt that P. sumatrensis, Sauss., the 

 type of which is in the British Museum, and Avith which 

 Cameron's species have been carefully compared, is the same 

 species. 



Polybia (Parapolybia) orientalis, Sauss.

/. fuscipennis. Cam., from the Khasia Hills, is certainly 

 nothing more than a colonr-variety of P. orientalis^ from 

 •whicli species it differs (o) by the absence of the longitudinal 

 yellow stripes on the mesonotum, [b] the yellow at the base 

 of abdominal segments 3 and 4 forms a continuous band 

 both dorsally and ventrally, and is not broken dorsally as in 

 P. orientalis. Tlie general ground-colour also is more choco- 

 late-brown than in that species, and the antennae darker.
