454 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Ilab. — N. S. Wales: Narromine (E. W. Ferguson). 



Readily distinguished from all others of the genus by its 

 remarkable antennae. The sculpture of the head is also 

 remarkable. 



Rytus porcellus Schfs. 



There are before me three males (from the Blue Mountains 

 and Sydney) that agree well with Raffray's notes on the types 

 of li . 2}orccnus, and I believe them to be that species. He 

 thought that the species was probably 2i. coniiger, but this 

 is not the case, as the latter is a smaller species, with rather 

 coarse punctures ; .and is much like B. Kinyi. 



Hamotopsis metasternalis, n.sp. 



cf. Reddish-castaneous ; head, prothorax, and abdomen 

 somewhat darker than elsewhere. With moderately dense, 

 and not very short, yellowish pubescence. 



Head, excluding eyes, decidedly longer than wide; with 

 dense and rather coarse punctures, except in middle, which 

 is shining and with two conspicuous but rather small f ovese ; 

 front rather deeply impressed between antennary ridges. 

 Antennae moderately long, first joint, from above, about as 

 long as the two following combined ; from the side, the three 

 following combined ; ninth slightly wider than eighth ; tenth 

 slightly longer and wider than ninth ; eleventh very large, 

 largely produced on one side. Palpi with apical joint very 

 lai'ge, about as long as the two basal joints of antennae. Pro- 

 thorax strongly convex, longer than wide, widest at about 

 apical third, thence rather strongly diminishing in width to 

 base ; each side near base with a rather large impression, the 

 two connected across middle by a curved line ; behind this 

 line the punctures are denser and coarser than in front of it. 

 FAiftnt lightly transverse; each with the sutural stria distinct 

 and commencing in a small fo\ca, the dorsal subfoveate near 

 base, but not traceable to middle ; with small punctures.
