Hah. — Atherton, N.Q. Rare; April, 1907. A single male^ 

 and several females, taken by Mr. E. Allen. 



Martin described this species from a unique female (loc. Queens- 

 land) in the de Selys Collection. I was at first inclined to con- 

 sider my specimens as a distinct species, partly because of their 

 greater size and some small differences in details of colouration, 

 but more especially because I sent a pair to M. INTartin and he 

 did not, apparently, connect them with his type. However, the 

 two agree in all essential points, and in particular, I do not know 

 of any other species in which the labrum, has a black border 

 carrying a row of small yellow hairs — a most distinctive character 

 for this species. 



•The specimen in the de Selys Collection must have come from a 

 different locality (possibly Gayndah), and this may account for 

 minor differences. 



Mr. Allen notes that the specimens he took were apparently 

 not long emerged, and were flying in the long grass between the 

 creek and railway station; they could have been caught easily by 

 the hand. This is probably, therefore, a winter insect in North 

 Queensland. 



7. AusTROGOMPHUs ARBUSTORUM Tillyard. 



At Cooktown, in January, 1908, this insect was only just 

 emerging, and the few specimens I took were considerably smaller 

 than those found at Kuranda. 



8. AUSTROGOMPHUS PRASiNus Tillyard. 



Common at Cooktown, along the Endeavour River, where I 

 found it freshly emerged in January, 1908. The colours are then 

 bright orange-yellow and black, as in A. Risi Martin, to which 

 this insect is closely allied. The rich green colour, which suggested 

 the name to me, is clearly only found in the maturer insect. 



9. AusTROGOMPHUS ARENARius Ti!l3^ard. 



Occurs sparingly in the grass along the banks of the Endeavour 

 River, but is by no means common. There is also in the Macleay 

 Museum, Sydney, a specimen from Derby, N.W. Australia, in
