apex of median, pi'oduced into a narrow angular point under the 

 louver margin of the first cubital cell; 2nd discoidal cell angular, 

 receiving the sub-discoidal cell in the centre of the apical 

 margin ] anal cell large, swelling out at apex : hindwings with 

 costal nervure straight, narrow; sub-costal nervure extending 

 beyond the front of the radial cell ; median cell long, broad 

 at the apex; 1st cubital cell broadest at the base ; both the 

 transverse cubital nervures showing fovea in the centre; neither 

 the cubital or discoidal nervure comino- to the outer edse of the 

 wing; the posterior margin very much thickened from the base 

 half way round the basal lobe. 



Abdomen slender, cylindrical, tapering to the apex, truncate at

9 Imago. — -Four lines in length, larger than the male, with the 

 whole of the head and thorax, except the apical edge of the 

 metathorax, bright reddish-brown, ocelli black; antennae without 

 prongs, somewhat longer, 3rd joint longest, slender at the base, 

 swelling out at the apex; 4th- 7th decreasing slightly in length, 

 but increasing in width towards the tip; 8th larger, and truncated 

 on the outer edge. 



Abdomen broadest at the base, tapering to the tips, somewhat 

 flattened on the dorsal surface; anal segment cone-shaped, trun-

^a6.— Melbourne, Yictoria; larvae feeding on the foliage of 

 Eucalyptus globulus (Coll. Mr. Chas. French). 



This handsome insect was sent to me by Mr. French, who stated 

 that it was doing a great deal of damage to the foliage of the Blue 

 Gum. At my request he sent me an ample collection of freshly 

 gathered leaves, containing specimens in all stages of growth, 

 except the eggs and very young larvae. When the sawflies 

 emerged they were very active, running about the jar, and trying 

 to make their way out; when touched they made a buzzing sound 

 like many of the Pergas. The protective rattle of the chrysalid. 

 when the leaves were picked up or handled is very remarkable.
