pellucidum, destroying more than half their number. The 

 ootheca is laid exposed on the surface of the leaf; the parasite 

 when ready to emerge fully occupies the whole space of the 

 destroyed eggs. 



Family CALLIMOMIDAE. 



PODAGRION NIGRICLAVA, n. Sp. 



9- Length 2'60 mm., exclusive of the ovipositor, which 

 is nearly as long as the body. Dull aeneous-green, the coxae 

 concolorous, also the hind femora except at the base and apex ; 

 rest of legs intensely yellow, the first two pairs of femora, and 

 apical half of posterior tibiae, more or less rufous ; antennae 

 golden-yellow, the club black. 



Teeth on posterior femora usually seven, distinct and 

 acute, 1 largest, 3 next largest, 2 shortest; sometimes there is 

 a very small additional tooth between 2 and 3, or there may 

 be a very small tooth between 5 and 6, but this is more often 

 confluent with 5, which thus may be broad and bidentate. 

 First funicle joint a little longer than wide, 7 twice as wide 

 as long, the club two-thirds as long as the funicle. Propodeum 

 with polygonal reticulation and numerous irregular carinae ; 

 median carina forking at one-fourth its length. Scutellum 

 not smooth at apex but the sculpture somewhat finer there. 

 Forewings hyaline ; stigmal vein short, shorter than the short 

 post-marginal. 



<$ . Like the female, but the anterior and intermediate 

 legs (except their coxae) intense yellow ; funicle joints rather 

 longer, the first less than one-half longer than wide, 7 

 quadrate, the club not one-half as long as the funicle ; 

 posterior femora with five acute teeth, 2 small, the others 

 large, almost subequal. 



Hab. — Northern Territory: Darwin (numerous females, 

 one male, labelled "From Mantid ootheca, 3/1/15, G. F. 

 Hill"). 



Types. — A female and male on a tag. 



Asymmetry in the femoral teeth is common. A closely 

 allied form to the other Australian species. Differs from 

 beneficium, Girault, in the colour of the legs and antennae, 

 and the branching of propodeal median carina ; from 

 vmshingtoni, Girault, and pax, Girault, in having the distal 

 funicle joints wider than long; from pavo, Girault, in the 

 colour of the male, and the larger number of femoral teeth in 

 both sexes ; from grotii, Girault, in the much shorter 

 ovipositor; from batesi, Girault, in the -colour of the legs, in 

 having the median carina on propodeum forking at base, and 

 in bearing one more tooth on the posterior femora ; hwu 

 hyalina, Girault, in having the scutellum sculptured at apex.
