australis Selys, also. The appendages of the male of A. angeli, 

 n.sp., are very distinct from those of all other species, but come 

 nearest, in form, to those of A. amphiclytus Selys. The new species 

 also resembles the latter somewhat by its colour-scheme, but is 

 easily distinguished from it by its much smaller size, by the bi- 

 colorous pterostigma, and by the two complete lateral bands of 

 the thorax. 



5. DlPHLEBIA EUPHCEOIDES CCERULESCENS, n.Subsp. 



A beautifully marked race, which differs from the type-form, D. 

 euphoeo'ides* Tillyard (Kuranda), as follows :— 



£. Wings slightly narrower, the black clouding not quite so 

 complete, but showing paler spaces in each cellule surrounded by 

 dark pigment. Black bands of thorax, slightly thicker. Abdomen 

 coloured as follows: 1, black with large central blue patches; 2, 

 blue, with' transverse black lines in sutures, a black dorsal line 

 along basal half, enlarging into a large flat spade-shaped dorsal 

 black spot towards apex; 3 as in type-form; 4-7 black with a pair 

 of conspicuous basal blue spots (these segments are wholly black 

 in type form) ; 8, blue, with a narrow elongate anchor-shaped dor- 

 sal black mark; 9, blue, with a short dorsal longitudinal black 

 stripe along basal half, and two small central points of black; 10, 

 black, with two round blue spots wide apart (closer in type-form) ; 

 sutures of 8-10 broadly black. 



£. Very similar to type-form, but with a generally darker 

 colouration and an intensification of the black parts of the epicra- 

 nial pattern. 



Hab. — Mount Tambourine, Queensland. December-January, 

 1913. Not common; occurs mostly on the rocky creeks half-way 

 down the mountain. I obtained a fair series of males and a smaller 

 number of females. 



Types: <j£, Coll. Tillyard. 



There seems to be an almost exact parallel between the limits of 

 distribution, and resulting variations of colour-scheme between 

 this species and Metathemis nigra, already dealt with. In both
