132 NOTES ON AUSTRALIAN COLEOPTERA, 



lateral border scarcely differentiated from disc, recurved towards 

 base, and, with it, closely, finely, evenWand distinctly punctured; 

 base subtruncate, very narrowly bordered. Disc convex, a little 

 foliate at the sides, these hollowed near base, flatter and more 

 horizontal anteriorly. Central line very feebly indicated by 

 smooth interval on centre; a transverse impression near to and 

 parallel with base. Scutellnin widely transverse, triangular 

 punctulate, carinate in the middle, raised anteriorly and strongly 

 depressed behind. Elytra {\0'D y. ^'b mm.) moderately convex, 

 widely ovate, epipleural border a little raised at shoulders, these 

 rounded : slightly narrower than prothorax at base, then rather 

 widely rounded, greatest width ahout middle, bluntly tapering at 

 apex. Sides narrowly bordered, this border not continued on 

 base, and throughout seen from above, with narrow horizontal 

 margin, with a row of evenly placed, rather distant and not large 

 punctures continued almost to apex. Disc smooth, except for 

 faint indications of three subobsolete costse quite disappearing on 

 apical declivit}', and even, minute, rather close surface-punctures, 

 Submentum coarsely punctured, with prominent triangular tooth, 

 gula without longitudinal furrow, prosternum and underside of 

 femora coarsely, abdomen more finel}^ closely punctured. Tibiae 

 straight and feebly spinose at apex, first joint of posterior tarsi 

 as long as the rest combined. Diuiensions — 16 5 x 8*5 mm. 



Hab. — Murchison District, West Australia. 



A single specimen, kindly presented by Mr. C. French, to whom 

 I dedicate it. Easily distinguished from A. Westivoodi Bates, by 

 shoiter, wider form, and the very different prothorax (wider 

 anterior angles, thin and opaque lateral border, and general shape). 

 The form of prothorax is somewhat trapezoidal, sides almost 

 straight, gradually widening from apex to base, so that the 

 maximum width is almost at the hind angles. It seems to me a 

 mistake to define the genus of a group like the Nyctozoilides as 

 rigidly in smaller details as Bates has done in the case of Agas- 

 thenes, as almost every new species would require a new genus. 

 In this case Bates' generic diagnosis must be slightly modified to 

 include A. Frenchi, since (1) the gula is without a longitudinal
