50 Arthar M. Lra : 



At once distinguished From //inirfa/ns by the club ; this is hirger, 

 of somewhat different shape, and much more hollowed out^ with the 

 hollow highly polished ; from ahove it appears as a thin hollow shell. 

 The metasternal depression is hounded on each side by ridges or 

 carinae ; of these there is one on each side, commencing at the middle 

 coxa, and extending to the middle, when it turns back so as to become 

 V-shaped ; at its end it meets a similarly forked carina, the point 

 of meeting being nuirked by an acute recurved spine or tooth, l)elow 

 this there is a smaller tooth ; in pioictatus the sculpture is on a 

 smaller scale and less complicated. 



The specimen obtained (in Septemljer) remained motionlesfs for a 

 little while after the covering stone was removed. It then started 

 to move slowly, but as soon as touched folded its appendages together, 

 much as do the species of Diplocfdei^. 



Ell plcrtopa erfatnmwae, n.sp. 



Bright pale castaneous, abdomen very little darker ; appendages 

 almost flavous. Rather densely clothed with very short pubescence. 



Head moderately transverse ; a large fovea on each side, not quite 

 closed in front and meeting in front ; base distinctly notched in 

 middle. Antennae rather thin, almost extending to base of prothorax ; 

 club three-jointed, ninth and tenth joints rather small, although 

 larger than the preceding ones, eleventh ovate, apex obtusely pro- 

 duced. Prothorar rather lightly transverse, sides rather strongly 

 rounded at apical third, thence decreasing in width to base ; near 

 base with a strong transverse impression, slightly dilated in middle, 

 and foveate on each side : median line rather short and shallow, 

 not extending to apex or subbasal impression. Elytra parallel-sided, 

 slightly longer than wide, subsutural and dorsal striae commencing 

 at base in small foveae, the dorsal striae scarcely traceable 

 to middle ; punctures indistinct. Abdomen slightly longer than 

 elytra, very feebly increasing in width to apical fourth ; second seg- 

 ment with a small transverse l)asal tubercle, second t<i fifth sul)equal 

 in length. Lcy-'^ moderately long. Length \\ mm. 



Hah. — New South Wales: Sydney, from a nest of Ertatnitima 

 mefallieitm (A. M. Ijca). 



A small narrow parallel-sided species ; fairly close to depressirnflis, 

 but larger, more parallel-sided, cephalic impressions moi'e pronounced, 

 those on the prothorax not the same, etc. ; hasalix is more convex 

 and polished, antennae shorter and club stouter, etc. ; ziczac has 

 much stronger impressions and hn/nphilus very different clothing. 



From some directions the cephalic impressions appear to be closed
