Wings * for the most part richly suffused with amber, the colour being most intense 

 in the costal, subcostal, median, and cubital spaces, and also ah)ng the costal margin

* Mr. E. J. Tillyard kindly informs me that the wing-venation of <S'. uuiUastoni, as shown in a photograph 

 which I sent him, agrees exactly with that of his unique female of S. claviculata Tillyai'd, from N, Queensland ' 

 The New Guinea species is abundantly distinct, however, by reason of its considerably larger size and by the 

 greatly superior development of its ovipositor. He: also draws my attention to the extreme variability of 

 the extent and arrangement of suffused areas in the wings of Synihemis females, even in different examples 

 of the same species, and, in the case of bred specimens, in the same individual, according to age.
