660 NEW SPECIES OF AUSTRALIAN COLEOPTERA, X., 



Kostnun with carina partially concealed. Frothorax with a 

 distinct median line. Elytra trisinuate at base; with rows of 

 large, normally almost concealed punctures ; third and fifth 

 interstices subtuberculate in places. Basal segment of ahdo- 

 nien with a conspicuous median tubercle, second with a small- 

 er one. Front coxct widely separated ; tibiae rather conspicu- 

 ously ciliated, hind pair with a wide, shallow, subapical emar- 

 gination. Length, 5 mm. 



Hab.—lS^ew South Wales: Illawarra (H. W. Cox). 



Allied to J/, fuherculiveiitris, but both basal segments of 

 abdomen tuberculate. The prothorax normally appears to be 

 without granules, and on abrasion, at any rate on the disc, 

 they are seen to be absent. From above or below, the hind 

 tibiae are seen to have a conspicuous emargination from slight- 

 ly beyond the middle almost to apex, the tibiae at the middle 

 of the emargination being only about one-half the width that 

 they are before it, but, from the sides, the emargination can- 

 not be seen. 



Mandalotus arciferus, Lea. 



Mr. Davey has recently taken, at Portland (Victoria), some 

 specimens of this species, evidently in better condition than 

 were the types. They are clothed on the upper surface with 

 sooty scales ; with two (or four) patches of white at base of 

 elytra, some vague whitish spots near apex of prothorax, 

 whitish rings on femora, and whitish scales on under-surface 

 and head. 



The prothorax of the male is dilated towards, but not to, 

 apex. The elytral tubercles are fairly distinct on some speci- 

 mens, and there are two (or three) on third interstice, and 

 two on fifth, with some very feeble ones elsewhere. 



Two females have the apex of elytra with scattered spots, 

 and one has a longitudinal ochreous spot on each side of base 

 of prothorax. Between the eyes, there is a small granule, 

 much smaller than on the female of J/, inter ocular is; from 

 the female of that species it is also distinguished by its small-
