closely resembles those two species; from both, however, its 

 costate elytra and black shining colour will distinguish it.

" Oblongo-elliptica, fusca, in cavitatibus brunneo-squamulosa, 

 thorace rotundato, in medio ampliato, confertim tuberculato, 

 apice nonnihil producto, elytris porcatis, costis tuberculorum 

 nigrorum seriebus, humeris tuberculo majore insignitis, ad 

 suturam mucronatis." 



" (J. Elytris apice sensim ampliatis, ventre subtus apice exca- 

 vato, ano forfice validissima armato." 



"Long.corp.(rostro excluso) 1*2-13 millim. Lat. 4-5 mill. Long, 

 forficis 4-5 mm." 



" 9. Elytris ovalibus, versus apicem haud ampliatis, segmento 

 anali inermi." 



" Patria ; Australia orientalis." 



The above is Dohrn's description of the species; the size given 

 prohibits my regarding it as any of the species before me; while 

 in the description there is not sufficient to enable me to assign it 

 to any group. I have placed it near P. Wilcoxi merely because 

 that is the smallest species known to me; but the length of the 

 forceps quoted, would indicate a very different species. 



PSALIDURA METASTERNALIS, H.sp. 



(J. Elongate, subparallei; prothorax minutely granulate, elytra 

 foveo-striate, interstices thickly granulate; fascicles widely 

 separate. Black, opaque; clothed with muddy scales in the 

 depressions; seta3 black. 



Head convex, somewhat thickly setigero-punctate, punctures 

 extending on to rostral ridges. Rostrum short, thick, flat pos- 

 teriorly, shallowly excavate at apex; ridges flattened; basal sulci 

 rather feeble, median notch deep, extending anteriorly to form a 

 Y-shaped depression behind marginal plate. Mandibles rounded, 

 slightly produced in front. Prothorax(7-5 X 8 mm.) rotundate, 

 evenly rounded from base to apex, base truncate, apex truncate 

 above, feebly sinuous at sides, no definite median or ocular lobes; 

 collar-constriction faint, median line feeble; disc densely and
