Giant Robber Fly

Giant Robber Fly (Promachus, 蛮食虫虻属).

Comparing with descriptions in my trusty copy of Iconography of Forest Insects in Hunan China (1992), I think it is Promachus albopilosus. It is a real beast of a predatory fly: I have seen several over 3cm in length, perched in the lower parts of Yuelu Mountain.
