496 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



rather wide and depressed. Metasternum and basal segment of 

 abdomen scarcely visibly punctate in middle; apical segments 

 moderately strongly punctate; lamellse extending but little more 

 than half way to first suture. Length 1|-2J mm. 



Hah. — Tasmania (Mr. A. Simson, No. 3804), Hobart, Bruni 

 Island (Lea). 



Of four specimens under examination no two have the elytral 

 markings alike; on three of them the suture is narrowly piceous 

 throughout, on the fourth it is scarcely darkened. On one the 

 piceous markings form an irregular U behind the scutellum, and 

 about the middle of each an irregular h (correct on the left and 

 reversed on the right elytron) joined together by a transverse 

 fascia at about one-third from apex; on another specimen the h 

 is present but rather indistinct, and the basal U is not continued 

 across suture; on the third specimen the markings are much 

 narrower and consist of a short broad U near the base, a trans- 

 verse fascia at one-third from apex and a slightly curved and 

 disconnected stripe slightly nearer the side than suture; the fourth 

 specimen resembles the third to a certain extent, but the markings 

 are less sharply defined and the basal U appears as a V. 



Rhizobius corticalis, n.sp. 



Oblong-ovate, subdepressed, feebly shining. Reddish-brown or 

 brownish-red, prothorax slightly paler than elytra; head, under 

 surface (including epipleura?) and appendages dark testaceous (or 

 brownish) red; metasternum slightly infuscate or not. Densely 

 clothed with short yellowish pubescence (more or less waved on 

 elytra) interspersed with long brownish set?e, which are more 

 numerous at the sides than on the middle. 



Prothorax comparatively strongly punctate. Elytra densely 

 and strongly punctate. Intercoxal process of prosternum wedge- 

 shaped, its sides carinate. Metasternum distinctly transversely 

 wrinkled and (except for a rather large space about middle of 

 apex) coarsel}'- punctate. Abdomen densely punctate, punctures 

 less regular and smaller on basal segment than elsewhere, but a
