from head; front strongly biim pressed; median space convex; 

 lateral spaces wide and convex, bearing posteriorly (opposite 

 middle of eyes) the large anterior setigerous supraorbital 

 puncture; antennae moniliform, three basal joints glabrous. Pro- 

 thorax lightly transverse (1-75 x 2-25 mm.), wider across base 

 (1-8 mm.) than apex (1-4 mm.); anterior angles wide, rounded, 

 bordered; sides lightly rounded on anterior four-fifths, lightly 

 sinuate posteriorly, and meeting base at right angles; basal angles 

 sharply rectangular ; two setigerous punctures on each side, 

 posterior at basal angle; a wide basal impression on each side, 

 reaching base externally, bordered by a short longitudinal sub- 

 marginal ridge. Elytra convex, truncate-oval (4-2 x 2 8 mm.); 

 basal border dentate at humeral angles; lateral border reflexed; 

 stria3 punctate, 1-6 deep, seventh lightly but distinct^ marked; 

 interstices 1-6 lightly convex, seventh and eighth not separately 

 convex, eighth carinate towards apex, third bipunctate near course 

 of third stria; anterior puncture about middle of length, posterior 

 at beginning of apical declivity. Metepisterna (with epimera) 

 wide, a little longer than broad. Length 6 '8, breadth 2-8 mm.

Tribe PLATYSMATINI. 



Though not now dealing generally with the Australian Plat3^s- 

 matini, there are some points of interest that require notice, so I 

 take the present opportunity of placing them on record. 



(1) A Note on Generic Nomenclature. 



Teropha ■ Castelnau, 1867) should be used instead of Morphnos 

 (Schaufuss, 1867), which is too near Moi'phnus (Cuvier, 1817, 

 Aves). 



Pachymelas (Tschitscherine, 1902) must supplant Nurus 

 (Motschulsky, 1865), which is too near Niira (Hej^d., 1826, 

 Arachnida). I feel considerable doubt about the species referred 

 to Pachymelas being truly congeneric with those referred to 

 Nurus by M. Tschitscherine. 



C astelneaudia (Tschitscherine, 1891) will have to take the 

 place of Homalosoma and Trichosternus. Homalosoma (gen. ined..
