vein is longer relatively to the marginal. The latter is of much 

 the same form in all and can hardly be called punctiform in any. 



Oocto)ius Hal. 



Male antennae with 13 joints, the scape flattened and short, 

 the second joint very small and roundish, the following ones 

 subequally elongate, flattened and wide, but not so wide as 

 long. Antennae of female ii-jointed; scape very long, set on 

 an elongate pedicel, so as to appear obsoletely 2-jointed. and as 

 long as the three following joints together; club as long as the 

 five preceding joints together. Posterior ocelli wide apart, 

 perhaps placed close to the eye margins, the collapse of the head 

 in dried specimens making it mipossible to ascertain this point. 

 Scutellum large and elongate, longer than the mesonotum ; the 

 axillae encroaching little or not at all on the scapulae ; propc- 

 deum with two raised lines or longitudinal carinae. Tarsi 5- 

 jointed. Apical cilia of front wings short, many times shorter 

 than the greatest width of the wmg. Abdomen pedicellate. 

 (For figures of antennae see PI. XIII fig. 2; the lower two an- 

 tennae representing male and female of this genus.) 



Ooctonns australcnsis, sp. nov. 



Black, shining, antennae of the male black, of the female 

 with the scape mostly pale yellowish-brown, the second joint 

 also more or less brownish, the following three blackish, the 

 sixth also dark but less so than the preceding, 7th, 8th and C)th 

 white, loth much wider than the 9th and black, club black. Legs 

 brownish yellow or testaceous, posterior tibiae more or less 

 darkened. Abdomen pedicellate, brownish black or piceous.

Hab: Cairns, Queensland; two examples extracted from eggs 

 of a conspicuous Tcttigonia common in the cane fields. 



Gonatoccnis, Nees. 



Female: Antennae Ti-jointed, the scape elongate, al)out equal 

 to the next three joints together, second joint widened, much 

 wider on its flat surface than the following; flagellar joints not 

 differing greatly in length, the basal ones being, however, rather 

 shorter than the following ; club as long or longer than the three 

 preceding. Front wings with short apical cilia, several times
