Phojiecoderus subdepeessus Guer. 



I only kuow P. elegans Cast., from the Melbourne district, as a species which 

 suits Putzeys' description of P. subdepressiis Guer. Putzeys' treatment of the 

 two sjjecies P. subdepressus and P. elegans in his "Revision" of 1873 leaves the 

 impression on my mind that only one species was before him. I have not seen 

 any species from Tasmania that is P. subdepressus Guer. 



Promecodeeit.? modestus Cast. 



This species is said by Castelnau to be from Tasmania. Castelnau's descrip- 

 tion might ajiply to P. longus SI., but. in his Revision. Putzeys, with Castelnau's 

 single specimen (?) before him, says it has the basal angles of the prothorax 

 rectangidar. I have not seen it from Tasmania, or the mainland.

(^ P. degener Guer.) 



A variable species in size and appearance. I attribute to it all Tasmanian 

 specimens with the basal angles of the prothorax very wide (open), and which 

 have in the c? the following characters: — Ventral segments 3 — 5 plurisetose in 

 middle, apical segment with three setigerous punctures on each side, placed tri- 

 angularly (two of the punctures marginal) ; anterior femora suddenly dilatate on
