Hah. — Swan River, Chidlow's Well, Pinjarrah, W.A. 



Specimens may frequently be obtained from the dead crowns of 

 various species of Xanithurrhoea and occasionally from similar 

 •situations in Kin'iia austraHx. The size, and to a certain extent 

 the colour, are variable. The species is moderately close to iynarius, 

 Pascoe, from which it differs in its finer puncturation, elytral 

 interstices, but especially by the apical segment of abdomen. 



Deretaphrus parviceps, n sp. 



Moderately shining, sides of elytra subopaque; dark reddish- 

 brown; legs and apical joints of antennae slightly paler. 



Head small, densely and rather coarsely punctate, neck rather 

 ■sparsely punctate, a few shallow depressions close to neck; clypeal
