which are not all of equal importance.* In both cases 

 the $$ seem to be extremely common, while the <$<$ are 

 hardly known at all. It is most desirable that these 

 doubts should be cleared up by rearing larvae of both 

 forms on a large scale, which would be sure sooner or 

 later to procure the evidence that is wanted. (Kirby "s 

 " sericea " <$ in B.M. appears to me identical with guerinii 

 <$ of Westwood, and I think it likely that " chalybea " <$, 

 Froggatt, is either the same, or perhaps more probably 

 the true ventralis. Unfortunately Mr. Froggatt does not 

 mention the colour of the antennae in his species.) 



The Types of guerinii {$) and smiihii (9) are both at 

 Oxford. Westwood gives no particular locality for either, 

 but specimens of smiihii in B.M. are from Victoria. 



— Antennae not black, but luteous or ferruginous .... 21. 



21. Larger (about 19 mm. long) and paler. Yellowish with the 



apices of hind tibiae and tarsi, and usually the sides of the 

 mesonotum blackened . . . lewisii, Westwood (18.3f>). 



Tasmania and Victoria. 



— Smaller and darker, brownish-testaceous, with legs and sides 



of mesonotum concolorous. (P. froggatti (9), Rohwer, in my 

 opinion certainly belongs to this species, and " newmanni" 

 Westw., and " sellata," Kirby, are oo of the same insect.) 

 ferruginea, Leach = froggatti, Rohwer. 



N. S. Wales and Victoria. The Type of ferruginea, 

 Leach, according to Kirby, is a $ in B.M. Westwood, 

 however, says that it is a J at Oxford; but he cannot 

 be right as to this, for Leach describes a 2 only, and says 

 distinctly Mas Intel ! The Types of froggatti ($) and 

 sellata (J) are in B.M. That of newmanni <$ is at Oxford. 



22. (I) Antennae with only 5 joints really separated from the 



"club," but the latter is sometimes constricted (on one side 

 only, not all round !) so that in certain aspects the antennae 

 look seven-jointed. A more important character is the 



* The character of " three cubital cells only," on which Guerin 

 founded his Subgenus Pseudoperga for lewisii and venfralis, is 

 certainly not reliable. The first cubital nerve is not always absent 

 in any species of the group, and very seldom so in ferruginea, Leach, 

 which clearly belongs to it.
