Polistes, and consequeutly we might reasonably expect the species to be less frequently met 

 with than its more powerfully built and pugnaceous neighbour. It is noteworthy, too, that 

 the species of Icaria are more uniformly coloured and, more particularly, darker coloured than 

 are those from India and Hindu-Malaya. 



It is noteworthy that of the 35 species of Aculeata taken by Mr. Lorentz no less 

 than 21 belong to the Vespidae, as against 7 Pompilidae and 5 Sphegidae, the other groups 

 most numerously represented.

The abdomen is black ; except in some examples the sides of the basai 2 segments 

 are tinged with brown. The flagellum of the antennae is rufous below. There are only 

 workers in the collection. It seems to be a smaller form than the typical race.

Apparently a common species. It is, no doubt, as I hâve suggested, /. c. supra, a form 

 of P. tepidus F. It may be 30 mm. in length. No doubt the V"te du BUYSSON in his forth- 

 coming Monograph of Polistes with the ample material at his command, will be able to 

 define the limits of the species. Smith records P. tepidus from Waigëu, Misol, Aru, Kei, 

 Batjan, New Guinea, the Solomon Islands. The following from Batjan, where it was taken 

 by Mrs. DE BEAUFORT in December, forms another race.

Black, with the following parts dark rufous : the clypeus except the apical fourth, the 

 outer orbits, the vertex behind the ocelli, the upper part of malar space, the mesonotum 

 except round the edges, the black on the hinder part broader than on the sides, and a line 

 down the centre; a broad irregular band on the basai half of the 2nd abdominal segment, the 

 mark roundly narrowed at the base and at the sides, the apex almost transverse ; a narrow
