The type was described from a male specimen whose antennae 

 were wanting, and thus Westwood made the mistake of placing 

 it in the genus Perga. 



I have collected a large series of both sexes, with the curious 

 double-tailed green larvae, upon the wild raspberiy-plants on the 

 Tweed River, N.S.W. When visiting the British Museum in 

 1908, I went through the cabinets of sawflies, and recognised mv 

 species under the name of Perga macleaii.

A number of cases have been recorded from the Roma and 

 Mitchell districts, Southern Queensland, of the death of cattle 

 that have acquired the abnormal habit of eating the larv?e of 

 these sawflies. The sawflies appear in the early summer in the 

 open forest-country in enormous numbers, and deposit their eggs 

 on the foliage of the ironbark-trees. The resultant, long-tailed, 

 slender, green larvae are so numerous, that they completely strip 

 all the foliage off the trees over a large extent of the ironbark 

 forests. When full}' fed, they crawl or fall to the ground, and 

 congregate at the base of the tree-trunks in regular heaps.

 of licking up these moribund larvne; and quite a number of the 

 young stock, in these particular areas, have died from their par- 

 tiality to this change of diet.
