TWO NEW SPECIES OF PHYTOPHAGOUS HYMEN OP- 

 TERA BELONGING TO THE FAMILIES ORYSSIDjE 

 AND TENTHREDINIDjE, WITH NOTES ON OTHER 

 SAWFLIES. 



By Gilbert Turner. 



The first of these insects agrees in all particulars with Latreille's 

 genus Oryssus, the type of which is such a peculiar insect % that 

 Dalman suggested that it should be separated from the TJroceridaz 

 and raised to the rank of a family; this has since been done, and 

 it is now placed before the Uroceridce. This family contains only 

 about 20 species in the single genus Oryssus, which are very rare 

 but have a wide geographical range, though the species presently 

 to be described is the first recorded from Australia. The second 

 belongs to the genus Clarissa of the family Tenthredinidce, the 

 type of which was described by Kirby from a specimen collected 

 and forwarded by me from this district (Mackay, Q ). 



Oryssus Queenslandensis, n.sp. 



9. Long. corp. 9-10-5 mm.; exp. al. 13-5-15 mm. 



Black; a very narrow line of golden-yellow pile on each side of 

 the 1st abdominal segment, a broader line of the same on each 

 side of the 2nd, a roundish spot of the same on each side of the 

 3rd and 4th, nearly the whole of the upper surface of the 5th 

 and the entire upper surface of the 6th and 7th clothed with pile 

 of the same colour; the pronotum and front of the head also 

 show traces of yellow pile, the latter, however, very faintly. 

 Legs red, darker on the outer than the inner surface. Forewings 

 fuscous, except the tips and extreme bases, which are hyaline, 

 and a broad band rather nearer the base than the apex of a
