punctate. Legs piceous, the anterior light red with the tibiae lightly 

 tridentate, the first and second joints of the posterior tarsi long 

 and about equal. 



Length, 2 1 lines. 



Hah. — Melbourne, 



44. LlPARETRUS LURIDIPENNIS, n. sp. 



Like the last species. The head and thorax fulvo-villose, the 

 puncturation fine but more rugose. Elytra paler reddish-yellow, 

 more obsoletely punctate, and more narrowly edged with black. 

 The body is rather densely cinereo-villose beneath, the propy- 

 gidium exposed and with the pygidium clothed with short gray 

 scales as well as hairs. Legs piceous, anterior tibiae bidentate, the 

 terminal tooth long and straight, the other scarcely visible, the 

 first joint of the posterior tarsi as long as the second. 



Length, 3 lines. 



Hob. — King George's Sound. 



45. Liparetrus rugosus, n. sp. 



Of more elongate form than the preceding, and entirely of a 

 subnitid brownish-black, more or less clothed all over with long 

 flaxen hairs. The clypeus is broadly oval and narrowly reflexed ; 

 the puncturation of the head and thorax is dense and somewhat 

 vermiculate ; that of the elytra is irregular and rather rugose, the 

 three geminate striae of other species only showing as obsolete 

 ridges. The legs are piceous-red, the anterior tibiae tridentate, 

 the inner spur short, the first joint of the posterior tarsi shorter 

 than the second. 



Length, 3 lines. 



Hob. — South Australia. 



46. Liparetrus collaris, n. sp. 



Elongate, oval, black, subopaque. Head finely punctate, clypeus 

 large, broadly reflexed, rounded at the angles, slightly emarginate 

 in the middle, and covered with long erect blackish hairs. Thorax 

 minutely punctate, the median line distinct near the base, and the
