560 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiii., 



T am satisfied that all the preceding species belong to Xylo- 

 'philus, or to some of the many subgenera proposed at its expense; 

 but so many, apparently strikingly distinct forms have been 

 separated from that genus, and later on reunited with it, that it 

 seems desirable not to propose any new genus on species that 

 could, by any reasonable probability, be referred to it. It is 

 probable that the present, and some of the following species, may 

 be considered worthy of generic rank, but, for the present, they 

 are referred to the main genus. Whether this and the next 

 species are allowed to remain in XylojDhilufi or not, however, 

 they should always be generically associated. 



Xylophilus subserraticornis, n.sp. 



^. Black, prothorax flavous, parts of legs obscurely flavous. 

 Moderately clothed with short, depressed, ashen pubescence; 

 elytra, in addition, with a few, fine, upright hairs. 



Head and appendages as in preceding species, except that the 

 median line is still more feebly impressed, that the punctures are 

 slightly more distinct, and that the antennae have a slightly more 

 serrated appearance. Prothorax slightly transverse, and dis- 

 tinctly narrower than head, base and apex equal, sides gently 

 rounded, with an impression across middle at apical third, rather 

 shallow on disc but fairly deep on sides, with a conspicuous, curved, 

 medio-basal impression, and a small, round fovea on each side; 

 punctures much as on head. Scutellum minute, within a shallow 

 depression. Elyt7'a rather long, much wider than prothorax, 

 almost parallel-sided to near apex, with a vague swelling on each 

 side of scutellum; punctures dense, sharply defined and of moder- 

 ate size, becoming smaller posteriorly. Sterna and abdomen much 

 as in preceding species, ^ind-femora each with a conspicuous 

 pad of pale pubescence on hind-margin from base to near apex. 

 Length, 2 J mm. 



7/«6._N.S.W.: Jenolan (J. C. Wiburd). Unique. 



Structurally close to the preceding species, but with flavous 

 prothorax, and clothing of hind-femora somewhat different. The 

 eleventh joint of botli antenn?e, and the middle legs are missing 

 from the type.
