Hob. — South Australia, and King George's Sound. 



This species forms the type of a distinct and perhaps a numerous 

 group, easily recognizable by the less convex penultimate segment 

 of the abdomen entirely covered by the elytra which are dilated 

 at the apex. Burmeister makes this peculiarity the basis of one of 

 his two subdivisions, but he has made the mistake of taking the 

 L. concolor of Erichson, as identical with this species. The four 

 following species belong to this group : — 



70. LlPARETRUS OBSCURUS, n. Sp. 



Broadly ovate, black, opaque, elytra dark reddish-brown, glabrous 

 above, cinereo-villose beneath. Head minutely punctate, the 

 clypeus more coarsely, with the apex broadly rounded and reflexed. 

 Thorax less densely punctate than the head, the median line 

 distinctly marked. Elytra with the geminate stria? distinct, the 

 intermediate spaces lightly punctate. Pygidium rather rugose, 

 carinated in the middle, the propygidium covered, or nearly so by 

 the elytra. The anterior tibia? bluntly tridentate. 



Length, 2^ lines. 



Hob. — South Australia. 



71. LlPARETRUS NITIDIOR, n. Sp. 



In form like L. obscurus, but with the elytra of a nitid, slightly 

 iridescent, red colour, and with a more distinct puncturation. The 

 clypeus of the male is narrowed, truncate and reflexed at the apex, 

 the angles obtuse, and the sides widening behind. The thorax is 

 opaque, very minutely punctate and rather thinly clothed on the 

 margins with long erect blackish villose hairs. Elytra red, nitid, 

 thinly but distinctly punctate and geminate-striate, at the base and 

 suture narrowly margined with black. Body beneath and pygidium 

 cinereo-villose. Legs piceous, anterior tibia? tridentate. 



Length, 2^ lines. 



Sab. — South Australia. 



72. LlPARETRUS LATIUSCULUS, n. Sp. 



Differs from L. incipennis in being smaller, more nitid, more 

 minutely punctate, with the thorax less thickly fringed beneath
