Hah. — Coen River, Cape York (H. Haeker), Queensland (Brit- 

 ish Museum). 



Two male specimens examined, one taken by Mr. Haeker, in 

 1906; a second, labelled Queensland 77-27, in the British Museum 

 consignment to me. The tibial characters are remarkable, and are 

 shown in my outline figure; while its highly polished surface, cylin- 

 dric form, large seriate punctures, and less produced angles of 

 thorax, easily distinguish it from the common M. laticollis Pasc. 

 Type in the Author's Coll.

 narrower at apex, feebly bisinuate at apex (a little

 attenuated but continuous throughout at apex, base without raised 

 border, sides with narrow sulcus within border, widened into a hori- 

 zontal lamina towards the anterior angle, base bisinuate; disc 

 minutely not closely punctate, with two large and deep basal
