Anoplius amcenulus, sp. n. 



2 • Olypeus about three times as broad as long, transverse at 

 the apex. Eyes almost touching the base of the mandibles, their 

 inner margins almost parallel, slightly curved towards the vertex, 

 where they are separated by a distance equal to the length of the 

 second joint of the flagellum ; posterior ocelli about half as far 

 again from the eyes as from each other. Antennae as long as the 

 head, thorax, and median segment combined ; the second joint of 

 the flagellum half as long again as the third and twice as long as 

 the fourth. Pronotum depressed, shorter than the mesonotum, 

 the posterior margin with a slight angle at the apex of the arch. 

 Median segment a little broader than long, with a faint median 

 sulcus at the base, obliquely sloped posteriorly. Abdomen fusi- 

 form ; second ventral segment without a groove. Posterior tibiae 

 cylindrical, spinose ; tarsal ungues with one tooth ; anterior tarsi 

 with a few short spines on the basal joint. Second abscissa of 

 the radius nearly twice as long as the third ; first recurrent 

 nervure received near the apex of the second cubital cell, second 

 close to the middle of the third cubital cell ; submedian cell a little 

 longer than the median ; cubitus of hind wing interstitial with 

 the transverse median nervure. 



Black ; with a transverse band of cinereous pile at the base of 

 the second and third dorsal abdominal segments ; silvery pile on 

 the clypeus, sides of the postscutellum, coxa?, and angles of the 

 median segment. Wings fuscous, an obscure band outside the 

 third transverse cubital a little paler. 



Length 13 mm.

This differs from nubilipennis Sm. in the structure of the 

 posterior tibia? as well as in other details. A. cinereus Fabr., a 

 common Queensland species, has paler wings with a fuscous 

 margin, and is a smaller species. 



Anoplius sericops, sp. n. 



$ . Clypeus about twice as broad as long, widely emarginateat 

 the apex, the labrum exposed. Eyes separated from the base of 

 the mandibles by a distance not exceeding half the length of the 

 first joint of the flagellum, their inner margins nearly parallel, 

 slightly curved towards the vertex, where they are separated by a 

 distance about equal to the length of the third joint of the 

 flagellum ; the posterior ocelli about as far from each other as 

 from the eyes. Front not raised into tubercles at the base of the 

 antenna? ; the second joint of the flagellum scarcely longer than 

 the third. Pronotum as long as the mesonotum, narrower than 

 the head, the arch of the posterior margin with an obtuse angle 

 at the apex. Median segment distinctly broader than long, with 

 a rather obscure median sulcus, truncate posteriorly. Abdomen 

 elongate fusiform ; second ventral segment without a transverse 

 groove. Tarsal ungues bifid ; posterior tibia? spined ; comb of 

 anterior tarsi very short. Radial cell short, less than twice as long
