cubic foot of earth, picked at random in an egg-bed, 600 of the 

 parasites emerged, and only fifty locusts. At night the insects 

 rested on blades of grass. I examined 264 specimens, of which 

 248 were females and sixteen were males. I found no varia- 

 tions in colour. 



Hah. — North Queensland: Herbert River, Nelson, near 

 Cairns. 



Hosts. — Locusta australis, Brunner ; L. danica, Linn. 



ScELio ovi, Girault, 1913. 



This species is common in the vicinity of Nelson, where it 

 has been bred from the eggs of Locusta danica, Linn. 

 Hah. — North Queensland: Nelson, near Cairns. 

 Host. — Locusta danica, Linn. 



ScELio FROGGATTi, Crawford. 



S . A male specimen of a Scelio, which is probably S. 

 froggatti, Crawford, wa« caught on the mainland, some miles 

 north of Cairns, December 24, 1911 (A. A. Girault). The 

 wings are but slightly infuscated and the antennae are honey- 

 yellow. This may be distinct from froggatti, of which only 

 the female is described by Crawford ; but since the host 

 (Locusta danica, Linn.) is to be found around Cairns, it is 

 quite probable that the same parasite would attack it. Length, 

 3'50 mm. 



SCELIO FLAVICOPvNIS, Sp, nOV. 



S . Black ; legs, except coxae, reddish-yellow ; coxae 

 black; antennal scape black; rest of antennae . golden-yellow. 

 Differs from aiistrcdis, Froggatt, and ovi, Girault, in structure 

 as follows : — Abdomen finely longitudinally striate ; second 

 and third segments with median areas not striate ; fourth 

 abdominal segment distinctly longer than third ; third funicle- 

 joint of antennae not dilated; wings hyaline, venation pale- 

 yellow, indistinct. Length, 3"50 mm. 



Described from a single male specimen caught while 

 sweeping in the forest, February 20, 1913. 



Hah. — North Queensland: Nelson, near Cairns (A. P. 

 Dodd). 



Type. — I. 1367, South Australian Museum. A male, 

 tagmounted, plus a slide bearing male antennae and forewing. 



Scelio nigeicoenis, sp. nov. 

 (S . Differs from flavicornis in having the femora much 

 suffused with black ; the antennae wholly fuscous ; first 

 abdominal segment striate ; remaining segments very finely 

 reticulately rugulose ; third segment distinctly the longest. 

 Length, 3 mm.
