354 MONOGRAPH OF THE GENUS SYNTHEMIS, 



rosy-brown, with black sutures; marked with creamy spots as 

 follows : — 1, pale on dorsum; 2, a pair of triangular spots, 

 auricles brown below, [)aler above, genital aperture edged with 

 cream; 3, a pair of basal triangular spots, a pair of central spots 

 somewhat elongated basally; 4-7, a pair of small basal spots, a 

 pair of oval central spots; 8, with central spots only; 9, brownish; 

 10 brown, pale on dorsum. Appendages: superior 3*3 mm., 

 wavy, approaching in a slight curve at tips, which are very 

 slightly enlarged; a tiny spine underneath near bases; colour 

 dark brown; inferior l'5mm., narrow subtriangular, pale 

 brownish, tips slightly upcurved (Plate vii., figs.4a and b). 



9. Very similar to male but somewhat larger, with greater 

 expanse of wing, duller colouration, thicker and more cylindrical 

 abdomen; pterostigma 4 mm., pale yellow in teneral specimens, 

 rich brown in mature ones. Wings hyaline^ even in newly 

 emerged specimens, with basal dark brown touch as in male. 

 Ovipositor conspicuous, reaching to middle of segment 10, tip 

 rather blunt, usually scarcely upcurved; very dark brown or 

 black. Appendages short, 0"8 mm., subconical, pointed, dark 

 brown (Plate vii., fig. 17). 



There is no doubt that this widely distributed species varies 

 considerably in many respects in different portions of its range. 

 I consider that the eastern and western Australian races are 

 sufficiently distinct from one another, and from tiie oceanic types, 

 to warrant subspecific names. They can be distinguished as 

 follows : — 



A.. S. macrostiy^na macrostigma Selys. — Hindwing : (J 33, ^ 

 32 mm. Black mark at base of wings very small in male, lying 

 in submedian space; vei'y large in female, reaching to arculus of 

 forewings and close up to triangle of hindwings, also in sub- 

 median space. Wings of female suffused with yelloivish. Front 

 with Si conspicuous dark T-mark, face and labrum pale. Append- 

 ages of male brown; 9-10 brown. Ovipositor of female, as 

 described by de Selys, very remarkable, reaching nearly to end 

 of appendages, with lamina slightly separated for part of their 

 length, confined again at tips. Types: ^. Coll. Selys("Oceania"):
