Voy. Astrol., II., p. 140. Fairm., Rev. Zool., 1850, p. 50. 



101. Rhizopertha Papuensis. n. sp. 



Oblong, parallel-sided, piceous black, sub-opaque ; antennas and 



legs piceous red. Thorax roughly punctate and opaque, projecting 



over the head, emarginate in front, retuse in front, toothed on the 



anterior lateral margin, and truncate and rectangular at the base. 



The elytra are three times the length of the thorax, and of the 



same width, with 9 or 10 rows of large punctures on each with 



slightly raised interstices ; they are only slightly retuse near the 



apex and without teeth or tubercle. A scanty whitish pubescence 



covers the whole body. 



Length, 4 lines. 



102. Genus doubtful. 



A very minute insect and only one specimen. 



Family. TENEBRIONID^E. 

 103. Nyctozoilus crenaticollis. n. sp. 



I am not at all sure of the genus of this insect. It is of an 

 opaque black colour all over and moderately convex. The head is 

 flat and punctate. The thorax is transverse, emarginate in front 

 and bisinuate at the base ; the anterior angles rounded, the 

 posterior rather acute,, the sides slightly rounded and coarsely 

 crenulate ; the elytra have each 9 distinct costae with broad smooth 

 intervals. The antennae have the first joint a little larger than the 

 others, the second a little smaller, they get gradually thicker to 

 the apex. 



Length, 9 lines. 



104 Prophanes submetallicus. n. sp. 



This and the following species are clearly of the same genus, but 

 the genus is probably not strictly Prophanes. Black, nitid, antennae 

 short, the last five joints flattened, enlarged and hairy. Head
