and of course I have not seen them, but two specimens 

 of " glaber $ " and many of nancarrowi $$ and $9 are in 

 B.M. named by the author.

 Stigma with pale (yellowish) apex. Antennae more than 

 15-jointed in the 2. Larger species.

— Stigma entirely dark. Antennae only 13- or 14-jointed (the 



apical joints are not very distinctly separated) in the 2. 



Smaller species nancarrowi, Froggatt. 



The very curious larva of Philomastix is figured in 

 Froggatt's "Australian Insects." It lias, like Perga, no 

 ventral legs and, unlike that or any other Australian 

 sawfly-larva, two paradoxically long anal appendages 

 (cerci ?). In both these characters it seems allied to 

 the Pamphilidae, but in these the cerci are comparatively 

 quite short ! I doubt, however, whether this similarity 

 is due to any special phylogenetic affinity between the 

 Australian and the Palaearctic species. The former is 

 much more probably a peculiar genus of the Pergidae, 

 with which it agrees in several characters (reduced number 

 of palpi, etc.) not found in any of the Pamphilidae.

PERGULA, n. g. 



I have only seen one species of this curious little genus, 

 and of that species only one specimen, a \ It is. however, 

 so distinct that T venture to describe it. 



Pergula turneri, n. sp. ;. 



Black, shining, feebly and shallowly punctured. Mouth-parts, 

 trochanters, knees, tibiae, tarsi, and genitalia sordidly whitish. 

 Apices of hind tibiae, and the tarsal joints following, more or less 

 infuscated. Wings hyaline. 



Antennae very shortly pilose, 7-jointed; the apical joint aboul 

 as long as the two preceding it. and rather longer than joint ;>. 

 The joints, except the apical and the two shorl basal ones, are all 

 obi onical, and the antennae as a whole might be called subclavate. 

 Face subquadrate, inner margins oi eyes parallel. Clypeus very 

 short (its apical margin slightlj sinuated inwards), antennae in- 

 serted close above it. Frons deeply sulcate longitudinally from the
