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



[The only Australian species is 0. sericatus, Mocsary, 

 described in Term. Fuz. (Feb. 1900) from New South Wales. 

 In the same year but some months later Mr. Gilbert Turner 

 described the same species from Mackay, North Queensland, 

 under the name Oryssus queenslandensis . The Type of 

 quet nslandensis, G. Turner (and many other specimens <$ and 

 2 from Kuranda, N. Queensland),* are in B.M., but not the 

 Type of sericatus, Mocs. In this species the fore-wing of 

 the $ is crossed by two conspicuous dark clouds, in the <$ 

 wing these are scarcely indicated (PI. XI, Figs. 1 and 2).] 



■ — Insertions of antennae between the eyes, never beloir them, and 

 separated from the mouth-parts by a visible "clypeus." 

 Top of head with no lateral rows of tubercles. Neuration of 

 wings more or less complete, always with at least 8 closed 



cubital cells in each fore-wing 2. 



2. Front tibiae with only one apical spine or " calcar." Antennae 

 many-jointed, long, slender, and filiform, with simply cylin- 

 drical joints (none of them dilated, pectinated, bifurcated 

 or otherwise paradoxically developed in either sex). The 

 dorsal apex of the abdomen is generally more or less acuminate, 

 and in the $ the ovipositor projects from below it (looking 

 like a stout needle with a blunt point). The scutellum is not 

 distinctly separated from the rest of the mesonotum. 



(Family Siricidae). 3. 



— Front tibiae with two calcaria. Antennae with the joints 

 seldom quite simple. (Often they are clavate, capitate, 

 pectinate, serrate on one side, pilose, etc., etc., see PI. XII, 

 Fig. 1 to 11.) Ovipositor of $ usually concealed within a bi- 

 valved chitinous sheath, which is always visible from beneath, 

 and may (or may not) project slightly beyond the dorsal apex 

 of the abdomen. Scutellum always distinctly separated from 

 the rest of the mesonotum . (Family Tenthredinidae). 4. 

 ."!. Costal area of fore-wing (/. e. the space between the costa and 

 subcosta) divided by a longitudinal "vein," hut with no 

 "nerve" crossing it transversely. Last dorsal plate of the 

 abdomen in the 'I deeply foveated before its apex, which is 

 compressed and drawn out into a straight nail-like process, 

 from beneath which the ovipositor may be seen projecting. 

 The latter is much stouter than thai of Ophrynopus, but the 

 structure in both cases is essentially the same. 



* These specimens were all taken by Mr. 1!. E. Turner emerging 

 from holes apparently made by hectics in a dead Eucalyptus tree 



in June or duly !
