206 AUSTRALIAN PSELAPHIDjE, 



It is more abundant in Australia than anywhere else, but is 

 found also in Tonkin, Manila and Sumatra. 



I have described one species as coming from Brazil, but very 

 likely the indication of locality is erroneous and the insect comes 

 from Australia. I will include it therefore in the following 

 synopsis : — 



A 2. Prothorax smooth and shining. 

 B 2. Transverse basal furrow of the prothorax 

 much interrupted in the middle by a strong 

 fovea; lateral foveas strong; antenna? short, 

 joints transverse, 9-10 larger, very trans- 

 verse, last one not longer than the two pre- 

 ceding ones together and very obtuse at apex; 

 last joint of the palpi triangular, rounded 



at apex — Rockhampton proportionalis, Schf s. 



B 1. Transverse furrow of the prothorax hardly 

 interrupted, the median fovea being hardly 

 visible. 

 C 2. Rather convex, prothorax irregularly ovate, 

 being broader in front, but the sides are well 

 rounded; antenna? not very thick, joints 3-S 

 moniliform, 9-10 broader and transverse, 11 

 regularly ovate; dorsal stria simple, even at 



the base— Australia Howitti, King. 



C 1. Rather flat, prothorax nearly cordate, u little 

 flattened on the sides which are obsoletely 

 and longitudinally sulcate; joints of the 

 antenna? 3-10 very transverse, 9-10 larger, 11 

 nearly as long as the three preceding ones 

 together, ovate-acuminate ; dorsal stria 

 geminate at the base — Australia (?), Brazil (?) Sharpi, Raffr. 

 A 1. Prothorax more or less finely reticulate and 

 opaque, more or less cordate, with the sides 

 flattened and more or less carinate. 

 B 2. Antennse short and thick, joints 3-10 trans- 

 verse. 

 <C 2. Rather flat and parallel, antenna? very short, 

 joints transverse, 9-10 increasing, 11 ovate, 

 obtuse, but not much broader than the tenth ; 

 dorsal stria simple — West Australia planus, Sharp.
