Hah.— Coolgardie (White, one example). 



I have placed this species in the genus Cerotalis because the 

 four anterior tarsi of the ^ have spongiose tissue on the under 

 surface of the same joints as the species of that genus; but it is a 

 wider and shorter species than any other as yet assigned to 

 Cerotalis, having more the facies of an Adutela (e.g., A. cuiicolor). 

 The very short linear epimera of the metasternum are not found 

 in the other species of Cerotalis. 



Genus Promecoderus.

Closely resembling P. ovipennis, SL, but differing by its darker 

 colour, darker antennas, piceous-black tibiae; narrower head, more 

 prominent eyes, smaller and less protuberant postocular pro-
