62 Mr. H. Oam|noii 07i 



Abdomen a little constrieted at segment 3, and somewhat 

 dilated at segments 6-10, with anothei* slight eonstrictiou 

 between 8 and 9. Black, with bright yellow markings on 

 2-8, as follows : — On 2 an oblique line rising upwards and 

 backwards from the auricle on each side, and ending, with- 

 out reaching the mid-dorsal line, by confluence with a large 

 wedge-shaped spot lying on its distal side; on 3-8 a pair of 

 moderately large rounded spots, lying centrally and close 

 together on 3, but becoming progressively more proximal, 

 wider apart, and more elongated transversely on succeeding 

 segments, supplemented on 3-5 by a pair of smaller rounded 

 spots at the base. 



Anal appendages (fig. 11) black. The upper pair as long 



Fijr. 1]. 



Synthemis fenella, sp. n., S i bolotype. 

 Anal appendages, in dorsal view. 



as segments 9 and 10 taken together, almost straight for 

 about two-thirds of their length, then becoming deeply 

 excavated internally, and finally giving rise to an internal 

 prominence and bending sharply inwards towards one 

 another. The lower appendage about two-thirds as long 

 as the upper ones, broad, upcurved, and ending in a 

 rounded point. 



In venation and coloration Synthemis fenella bears a close 

 general resemblance to S. claviculata, Till., from North 

 Queensland. It is immediately distinguished from that 

 species by its smaller size, it being, indeed, the smallest 

 known member of the genus.
