Notes.

The specimens from Shaanxi belong to the form intermedia (Chen, 1949) because the hind trochanters (as often fore trochanters) are entirely yellow and with tri-coloured (yellow, black and brown) second tergite and sternite latero-posteriorly. Colour of both mesosoma and head are very variable, e.g. the scutellum is black in most specimens but sometimes it has two yellow patches.
