prothorax. 
Meton tropicus. 
M. nigro-piceus, parce grisescente pubescens; prothorace trans-

This species is more nearly allied to the Aru Meton granulicollis 
than to the Australian Meton Digglesii, agreeing with the former 
in the style of coloration, the granulated prothorax, with its small 
lateral tooth and the narrower elytra, but differing in the broader 
and shorter prothorax, more trigonate elytra, the nearly trans- 
verse posterior band, and more ashy hue. Meton has been re-
