A female from Silago (Middle Sumatra) in June. This is 20 

 mm. long. The eyes are naked, and with very line network ; the 

 frontal band is narrow, posteriorly a little broader, in the middle 

 with a shining black-brown, below broader, stripe. The third joint 

 of antennae has a distinct tooth. Palpi with light ashy grey 

 tomentum, ending in a point. Beard as well as the pubescence of 

 fore breast and fore coxae light grey. The pale median stripe of the 

 abdomen consists of triangular spots; under side red-yellow, with 

 a black-brown apex. The neuration of wings is normal, the first 

 posterior cell at its opening a little narrowed. Perhaps Tabanus
