bicarinata by Cameron is identical with bidiensis. According to 
the descriptions, the stigma is pale testaceous in bidiensis, fuscous in 
“bicarmata.’’)

Genus APIS Linnzus 
Apis indica sinensis (Smith). 
The single worker before me agrees best with the Chinese 
subspecies, sinensis. It differs a little in wholly lacking bands 
of gray tomentum at bases of abdominal segments 3 to 5 and 
in the clear yellow scutellum. The dark hair on the front is 
very long and abundant. Possibly a Bornean race may be rec- 
ognized when we have more material. 
Apis florea Fabricius and A. dorsata Fabricius were also found 
at Sandakan. 
Genus NOMADA Scopoli 
Nomada sandacana sp. nov. :
