in i and the last lobately produced in the J ; and angularly 



projecting (" subserrate ") in the $? 10. 



9. Antennae always capitate, with six joints preceding the club, 

 all distinctly separated from it and from one another. Labial 

 palpi with 4 joints, maxillary with 0, the former much thicker 

 than the latter. 



7. Xyloperga, Shipp = Heptacola, Konow. 

 [For Synopsis of the species see p. 205.] 

 Antennae either capitate, or (in Kirby's Section II of the genus) 

 clavate from the third joint to the apex. In both eases only 

 •"".•joints at most (in one species only 4) precede the apical 

 joint. Labial palpi with only .'{ joints, maxillary with 

 only 4, the latter scarcely differing in thickness from the 



former 8. Peroa. Leach.

 10 Antennae 8-jointed, long and slender; joints 4 to 7 produced 

 at their apices in the <$ into pointed lobes; in the $ they are 

 nearly simple. Palpi as in Perga (labial 3-jointed, maxillary 

 i-jointed). In the fore-wings the 1st recurrent nerve is 

 sharply (angularly,) bent in the middle, and runs very obliquely 

 into the cubital vein half-way between the 1st and 2nd cubital 

 nerves; the 2nd recurrent is straight, and nearly interstitial 

 with the 2nd cubital nerve. 9. Phylacteophaga, Froggatt. 

 [The only known species of Phylacteophaga is eucalypti, 

 Froggatt, described in Proc. Linn. Soc. N.8.W., Vol. 14 

 (1899).] 



- Antennae with at least 10 joints. Both recurrent nerves are 



straighl and neither is interstitial 11. 



I I. Antennae in the o (the other sex is unknown) 10- to 12-jointed, 

 the intermediate joints shorl and stout with dilated apices. 

 ScutelluEO coarsely and rugosely punctured, dull, bisected 

 by a sharply-defined longitudinal narrow sulcation, its apex 

 produced into lobes as in Perga. and X/jloperga, but here the 

 lobes are proportionately longer and more sharply pointed. 



10. Cerealces, W. F. Kill. v. 

 [For Synopsis of the species see p. 287.] 



- Antennae with at least 15 joints, these in the $ resembling those 



of Cerealces scutellata. In the y the antennae are con- 

 siderably longer than in the J, the post-basal joints are slender 

 and elongate, hut those following become shorter and broader 

 as they approach the apex. The scutellum is somewhat 

 shining, its disc in certain aspects appeal's bituberculate, 

 but it is not (as in Cerealces) divided by a sharp central
