deeply sulciform. Scrobes deep, prolonged downwards. Eyes 

 subovate. Prothorax (6x7 mm.) evenly rounded on sides, 

 apical sinuosity feeble ; disc convex, densely covered with fine, flat- 

 tened granules, each bearing a long seta. Elytra (15 x 9 mm.) 

 evenly rounded, apex not greatly produced nor mucronate, base 

 subtruncate, humeral angles rounded; disc with longitudinal striae 

 feebly rugulate, not definitely punctate, each with single row of 

 setae down middle; interstices not much raised, with double or 

 triple rows of fine, somewhat obsolete granules, bearing long de- 

 cumbent setae; seventh marginal. Beneath, convex, fifth segment 

 with a punctiform depression at apex. Legs moderate in length. 

 Dimensions : Q.'2'l x 9 mm. 



Hab — ( ? ) "West Coast of Australia." Type in Macleay Museum. 



Evidently closely allied to T. ambiguus Macleay, and, like that 

 species, rather doubtfully referred by Macleay to Talaurinus. Un- 

 fortunately I have never seen a male, but have no doubt that it 

 will prove to be similar to T. ambiguus, which, whatever its posi- 

 tion, certainly does not belong to Psalidura. 



The locality given by Macleay, is, I believe, erroneous, and it is 

 likely to prove to be a Queensland insect.

(J. Large, robust, convex. Black, densely clothed with brown 

 scales variegated with lighter brown and white, setae yellow. 

 Head clothed with yellow setae, trivittate with white, prothorax 

 trivittate, elytra with white along inner side of each costa, also 

 maculate more internally, sides albo-vittate; beneath, each seg- 

 ment with yellow hair, larger on each side of ventral excavation; 

 posterior tibiae with a brush of yellow hair along inner side. 



Head strongly convex, densely setigero-punctate. Rostrum 

 short, little excavate, save in front; external ridges not pro- 

 minent, slightly convex in profile ; internal thick, more pro- 

 minent; lateral sulci shallow; median area linear, feebly depressed 

 throughout. Scrobes deep, widely open posteriorly. Eyes sub- 

 ovate. Prothorax (6x7 mm.) rotundate, apical margin feeblv 

 sinuous above, with rather a strong postocular sinuosity; disc 

 slightly depressed, and with a faint collar-impression; median
