668 NKW SPECIES OF AUSTRALIAN COLEOPTERA, X., 



than apex, median carina feeble or absent; with numerous 

 granules, but in places granulate-punctate. Elytra much wider 

 than prothorax, parallel-sided to near apex; with rows of large, 

 partially concealed punctures; interstices wider than punctures, 

 with rounded or transverse granules. Legs long, femora sub- 

 clavate. Length, 11-14 mm. 



9. Differs in being larger, legs somewhat shorter, and abdomen 

 more convex. 



Hah. — Tasmania : Mount Wellington (A. M. Lea). 



The male has the undersurface and coxse densely clothed with 

 snowy-white scales, a few of which have an opalescent gloss. On 

 the upper surface, the clothing (except at sides and apex of elytra) 

 is sparser, on the elytra mostly scales (some of which are sooty), 

 but on the prothorax (as also on the head, rostrum, and legs) 

 mostly more or less elongated setfc. On the female, the clothing 

 is more stramineous than white. The species is the largest of the 

 subfamily hitherto recorded from Australia; the largest female 

 before me measures 16^ mm., including its extended rostrum. 



Rhachiodes. 



In the Table of Erirhinides given by Mr. Blackburn, this 

 genus, with Olancea^ is separated from the others by the "scrobes 

 abruptly turned under the rostrum." 



Examining the sides of the rostrum of R. granulipes, R. 

 strenuus, and R. hicaudatus (which are certainly congeneric), the 

 scape is seen to be inserted fairly close to its apex, and the scrobe 

 to be bifid, the lower fork turning under the rostrum before the 

 eye is reached, but the upper fork continued until it touches the 

 eye. The lower fork is rather narrower than the upper one, and 

 usually receives the scape. The upper fork is sometimes partially 

 concealed by clothing, but, when looked for, is always plainly 

 visible. 



The scrobes of Encosmia cornuta are much the same, but that 

 species was referred to Encosmia "with considerable hesitation," 

 instead of to Rhaciodes, as its eyes are coarsely faceted, and claws 

 divaricate, and Mr. Blackburn regarded the claws as of primary 

 importance in the subfamily.
