yellow colouring, it much resembles a small Syyithemis rei/itia 

 Selys. Along the small rivulets close by, the very similar dragon- 

 fly, Syntheynis tasmanica Tillyard, was on the wing much more 

 abundantly. This latter species also frequently intruded upon 

 the domain of Synthemiopsis, and sometimes the latter would 

 make short excursions along the rivulets. S. tasmcuiica was, 

 however, easily distinguished by its duller colouration, which is 

 dark brown, with ochreous-yellow markings. 



A search was made for the larva of this species. Seeing a 

 newly-emerged specimen fly off from the side of a small rivulet 

 close to the swamp, a search amongst the reed-stems resulted in 

 the discovery of a fresh larval skin; the next day, another imago 

 was found transforming, and the exuviae secured. For compari- 

 son, the exuviae of Synthemw tasmanica were secured. These 

 latter closely resemble those of S. eusfalacta Burm. The exuvia? 

 of SyiUhpinmpsis are closel}^ similar to those of S. tasmanica, but 

 may be at once distinguished by their more slender build, more 

 prominent eyes, and more projecting frontal shelf. The wing- 

 sheaths are divergent, and the whole body hairy, as in all larvae 

 of Synthemini; while the teeth of the lateral lobes of the labium 

 are of about the same size and number as in S. pustalacta. The 

 whole larva strongly i-esembles that of C or dnU'tf aster, though of 

 course considerably smaller.
