344 ME. W. F. KIRBY — A REVISION OF 



Thorax reddish brown above and in front, with greenish spots between the wings, 

 and two broad pale-green shoulder-stripes, with two broad black bands beneath 

 the wings (slightly divided above), and a short black stripe on the space between. 

 Legs black, long, slender, with slender bristles. Abdomen reddish brown above, with 

 rather indistinct greenish spots on the sides; along the lateral carina runs a broad 

 black band, throwing up black rings on the sutures ; the ninth segment is almost 

 entirely black, and the eighth is marked with an oval yellow spot on each side, more 

 distinct than the green ones on the preceding segments. Wings hyaline ; pterostigma 

 oblong, yellow, between black nervures ; fore wings with 7 antenodal and 5 postnodal 

 nervures, the first postnodal not continuous; hind wings with 5 of each, the first 

 postnodal not continuous ; triangle of the fore wings nearly regular, only its outer and 

 upper angle being truncated.

Nannodythemis australis, Brauer. (Plate HI. fig. 5, 6 .) 

 Nannophya australis, Brauer, Reise d. Novara, Neur. p. 99 (1866). Male only. 



Long. corp. 20 millim. ; exp. al. 30 millim. 



Female. — Head yellow ; frontal triangle and back of the head shining black ; two 

 continuous yellow spots at the back of the occipital triangle, and about four yellow 

 spots on each side behind the eye. Thorax black above, with a sulphur-yellow stripe 

 on each side ; the sides yellow, with a black stripe above the middle pair of legs, and 

 the upper part of the suture behind slightly marked with black. Legs black, the 

 coxae and a short stripe at the base of the femora yellow. Abdomen tawny yellow,

Hah. Australia (Moreton Bay). 



Fylgia amazonica. (Plate LI. fig. 2, adult male; fig. 3, immature male.) 



Long. corp. 21 millim. ; exp. al. 38 millim. ; long. pter. 2 millim. 



Adult male. — Head reddish testaceous. Thorax black, the sutures and legs beneath 

 reddish. Abdomen with segments 1-5 black, the remainder red (or by abrasion 

 o-olden yellow). Wings clouded hyaline, a little smoky at the base; pterostigma 

 black. In the immature male the sides of the thorax and the base of the abdomen 

 are more inclining to reddish, and the wings are clear hyaline, except at the base ; in 

 the still younger male and in the female the insect is yellow, with reddish-brown 

 stripes in the middle of the thorax, obliquely on each shoulder and on the middle and 

 sides of the abdomen, and the wings are clear hyaline. 



Hab. Para. 



I suspect that this insect is Nannophya semiaurea, Hag. MS. ; but as this name is 

 inappropriate, being apparently founded on abraded specimens, I have not thought it 

 necessary to adopt it, as no description has been published.
