Posterior marginal cilia of caudal wings not as long as the blade's width 

 but yet over twice longer than the longest cilia of the fore wing; distal club 

 joint much longer than proximal. 



From one specimen, f-inch objective, 1-inch optic, Bausch and 

 Lomb. 



Male: Not known. 



Described from a single female specimen captured from a 

 window pane in a private residence at Nelson, North Queensland, 

 December 6, 1912 by Mr. Alan P. Dodd to whom I am indebted 

 for the specimen. 



Habitat: Australia, Nelson (Cairns), Queensland.

GENUS PODAGRION Spinola. 



Podagrion beneficium new species. 



Female: Length, 2.5 mm.; with ovipositor, 5.2") mm. Dark metallic 

 green with aeneous and bright bluish tinges; the face brighter green; ex- 

 serted portion of ovipositor black; antenna; black, excepting the dark 

 metallic scape which is rufous laterad and centrad but sometimes wholly 

 black; trochanters, knees, tibia; and tarsi rufous, the coxae and femora con- 

 colorous with the body, the caudal tibiae blackish for distal four-fifths; 

 distal tarsal joint black, the posterior tarsi often pallid yellowish. Oral 

 area black. Wings hyaline, the venation dusky. Teeth of posterior fem- 

 ora black; immediate base of abdomen more or less slightly rufous espe- 

 cially ventrad at proximal half. Eyes and ocelli concolorous, garnet. 

 Mandibles black at tip. Bright metallic blue especially on the abdoin> a 

 and legs. 



Lateral ocelli their own diameter from the eye margin. Head all over 

 and dorsal thorax densely polygonally sculptured or punctate, the punc- 

 tures moderate to fine, the abdomen, coxa; and femora polygonally reticu- 

 lated, the sides of the pro- and meso-thorax more roughly so. Genal suture 

 fine but distinct. Head, antenna? and thorax bearing short, greyish, moder- 

 ate pubescence; also on the posterior segments of the abdomen and the leg-;. 

 Posterior femora with six large teeth and a seventh minute one just proxi- 

 mad of the fifth tooth. Metathorax with a conspicuous v-shaped median 

 carina whose apex is at the meson cephalad; the large area cephalo-laterad 

 of each branch of the carina is densely punctuate nearly like the scutel- 

 lum while the mesal area included by the two branches of I lie carina is tin- 

 same but also traversed by an irregular, narrow median carina which sends 

 off oblique shoots making the area rugose. Laterad there are no carina- 

 excepting a thin longitudinal one a slight distance laterad of the spiracle. 

 The metathoracic spiracle is elliptical and slightly curved at one end. 

 thus subreniform. A fovoa is just caudad of it. 



Marginal vein of fore wing long but shorter than the submarginal, tin-
