Rev. F. D. Morice's Notes on Australian Sawflies. 253 



The only species recorded from Australia (australis, 

 W. K. Kirby = juvencus, L. !) is certainly a mere accidental 

 importation from the Northern Hemisphere, and no part 

 of the true indigenous Fauna. The $ is chalybeous (blue 

 with green and purple reflections). The <$ has a shining 

 testaceous abdomen, and the legs are mostly black, while 

 those of the $ are mostly yellowish. In both sexes the 

 bases of the antennae are testaceous. (The Type of 

 •• australis " — a $ — is in B.M.) 



f2. Sirex, L. (= Paururus, Knw.). 



— Costal area of fore-wing crossed by a transverse '"nerve," but 

 without a longitudinal " vein." 



Mr. Rohwer has described in Ann. and Mag. Nat. Hist. 

 (Nov. 1918) a new species of this genus from North Queens- 

 land (obtusiventris, Rohw. $). I have not seen the unique 

 Type, but it is described as black w r ith antennae and legs 

 ferruginous; 8 mm. long; with the abdomen "rounded 

 not tapering apically," this being a very unusual character 

 in a Xiphydria. (As the species does not seem to have 

 occurred elsewhere it is presumably indigenous.) For a 

 full account of its other characters see the author's 

 description (I.e.) 3. Xiphydria, Latr. 



4. .Middle and hind tibiae with calcar-like spines before as well as 



at their apices (PL XII, Fig. 19, PI. XV, Fig. 19) . . . 5. 



.Middle and hind tibiae with no spines other than the apical 



calcaria 12. 



5. Antennae apparently only 3-jointed (all joints beyond the two 



short basal ones being fused together and not distinguishable). 

 Fore-wings with a distinct " lanceolate cell " (PL XI. Fig. .'}). 



(Subfamily Arginae). <>. 

 - Antennae with at least 5 distinct joints. Fore-wings without a 

 lanceolate cell, the humeral nerve being undeveloped. (Mr. 

 Rohwer divides the genera of this section between two of 

 his " Families " — the Perreyiidai and the Pergidae, placing 

 Philomastix and Phylacteophaga in the former, Perga, Xyloperga 

 and Cerealces in the latter, but for certain reasons I hesitate 

 at present to take this view, and prefer to leave their precise 

 affinities undecided 8. 



6. Lanceolate cell crossed obliquely by a transverse nerve.* Hind- 



* This character does not occur in any other genus of the Arginae .
