AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XII—GIRAULT. 289 
closely, finely reticulated. Propleure closely, finely punctured, more or less striated. Metapleure 
finely, closely punctured; there are, on the last femur, about six irregular teeth, the basal three 
larger and more widely separated; they are as long as the coxe, which are closely and more 
finely punctured than the femora. 
The male is similar. As is usual with metallic species, the amount of the brassy and _ 
rufous tints varies. The fore tibia may be testaceous at the base and apex, as well as below. 
Probably the femoral teeth vary in size and number, as | have noticed to be the case with 
other species. The apical joints of the antenne form a not very clearly defined club. The 
sides of the mesonotum are bounded by a smooth furrow, inside of which is a flatter one, 
double its width, which again is bordered on the inner side by an irregularly crenulated 
furrow. The central part is finely rugose, divided into two almost equal parts by a narrow 
smooth furrow; the apical part is depressed in the middle. 
Except for the large alar cloud, this species does not differ from typical Podagrion, 
which have long been known to live in the egg-cases of Mantis. 
4. POCAGRION BENEFICIUM Girault. Female; male. 
Length, 2.5 mm.; with ovipositor, 5.25 mm. 
Dark bright metallic green with eneous and bright bluish tinges, the face brighter 
green; exserted portion of ovipositor black; antenne black, excepting the dark metallic scape 
which is rufous laterad and ventrad but sometimes wholly black or metallic; trochanters, 
knees, tibiz and tarsi rufous, the coxe and femora concolorous with the body, the caudal 
tibie 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 femora 
black; immediate base of abdomen more or less slightly rufous especially ventrad at proximal 
half. Eyes and ocelli concolorous, garnet. Mandibles black at tip. Bright metallie blue 
especially on the abdomen and legs. 
Lateral ocelli their own diameter from the eye margins. Head all over and. dorsal 
thorax densely polygonally sculptured or punctate, the punctures moderate to fine, the 
abdomen, coxe and femora polygonally reticulated, the sides of the pro- and mesothorax 
more roughly so. General suture fine but distinct. Head, antenne and thorax bearing short, 
greyish, moderate pubescence; also on the posterior segments of the abdomen and the legs. 
Posterior femora with six large teeth and a seventh minute one just proximad of the fiith 
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 punctate 
nearly like the scutellum while the mesal area included by the two branches of the carina is 
the same but also traversed by an irregular, narrow median carina which sends off oblique 
shoots making the area rugose. Laterad, there are no carinw 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 fovea is just caudad of it. 
Marginal vein of fore wing long but shorter than the submarginal, the postmarginal 
vein short but longer than the stigmal. Antenne 13-jointed, with one ring-joint which is 
distinet; funicle joints shortening distad, the distal two distinctly wider than long, the first 
two subequal, a fourth longer than wide, each slightly longer than the pedicel; joint 3 
quadrate; joints 4 and 5 subequal, slightly wider than long while joints 6 and 7 are subequal, 
each slightly shorter than joint 5; club long, ovate, much wider than the funicle, its. three 
joints subequal in length and as long as the proximal joint of the funicle. Mandibles dentate. 
The male is the same but the funicle joints are all distinctly longer, the club not wider 
than the funicle or hardly so, its distal joint short; antenna lighter distad and the abdomen 
differs as it should for this sex in this genus. The proximal funicle joint is nearly twice longer 
than wide, longer than the second joint and none of the joints of the funicle are wider than 
long.
