Polistes tenebricosus Lepel. var. 
This form! is not noticed in the “Fauna.” It is repre 
sented in the Indian Museum collection from Sikkim, Dehra 
un, and various localities in Assam, where it seems to be a 
fairly common insect. 
Polistes sagittarius Sauss. 
Probably distributed throughout India and Burma ex- 
tending to the Malayan sub-region and China. It is mainly a 
hill species. 
Polistes stigma Fabr. 
Widely distributed in India, Burma and Ceylon extending 
to Malaya. This species generally builds its delicate paper 
combs on trees overhanging a river or a pond. On the island 
of Barkuda in the Chilka Lake it nests along the shore, chief- 
ly on the southern end, but never in the interior. In a visi 
paid to Barkuda in the middle of April, 1922, several indivi- 
duals of this form were seen hovering just a few inches above 
the mud at the edge of a small pond that has been dug on the 
island. They would, not infrequently, venture out further and 
sip at the water. : 
Polistes maculipennis Sauss. 
This is almost entirely a hill species. Sikkim ; Mussorie ; 
Simla Hills ; Kumaon ; Nepal; Kashmir. It also occurs in 
South Africa. Three specimens in the Museum collection 
named P. marginalis shaitan Bingham are remarkably similar 
to this species. 
Polistes adustus Bing.
