494 MR. a. E. TURNER ON [May 12, 



eves Front depressed round the base of the antennae ; head 

 -a little broader than the mesonotum. Head and thorax opaque, 

 very closely and microscopically punctured. Pronotum depressed, 

 seen from above linear and transverse, sharply obliquely de- 

 pressed anteriorly. Mesonotum much longer than the median 

 segment the punctures on the mesopleurfe a little more distinct 

 than on the mesonotum. Median segment rounded, with a 

 median longitudinal sulcus from the base to the apex, a short 

 carina lying in the sulcus at the base ; along the base ot the 

 segment are a number of short oblique strife. Abdomen a little 

 longer than the thorax and median segment combined, closely 

 and minutely punctured, the apical margin of the segments 

 broadly depressed and smooth. The pygidial area is triangular, 

 much more strongly punctured, with short, stiff hairs springing 

 from the punctures. The first recurrent nervure is received at 

 one-quarter before the apex of the first cubital cell, otherwise the 

 neuration is as in Kohl's figure. 



Obscure blackish blue ; the clypeus, the base of the mandibles, 

 the scape of the antenna?, the apex of the femora, the tibite, and 

 the tarsi yellow ; the flagellum, the abdomen, and stains on the 

 tibife and tarsi light ferruginous; the tegulfe fuscous. Wings 

 hyaline, faintly iridescent, nervures ferruginous. 

 Leng-th 8-9 mm. 



(5 . Clypeus blue-black ; hypopygium pointed, with a spine on 

 each side close to the apex. Otherwise as in the female. 

 Length 7 mm. 



Hah. Townsville, Queensland (Dodd); Mackay, Queensland 

 {Turner) ; February and March. 



Described from two males and two females. 



Near Sericojjhorus Ucolor Sm., from W. Australia, but the 

 radial cell in that species is appendiculate and the head much 

 broader. 



ZoYPHiuM RuroNiGRUM, sp. n. (Plate XXVI. fig. 8.) 

 S . Mandibles deeply notched on the outer margin, acute at 

 the apex, not bidentate. Clypeus very broadly rounded at the 

 apex, the apical margin depressed, without minute lateral teeth. 

 Antennfe about one-third as far again from each other at the 

 base as from the eyes, the first joint of the flagellum shorter than 

 the second, globular, the second shorter than the third, the apical 

 ioint massive and longer than the others, the antennae are a little 

 longer than head and are gradually thickened to the apex. The 

 inner orbits of the eyes are nearly parallel, very slightly con- 

 vergent towards the vertex. The eyes on the vertex separated 

 by a distance scarcely equal to two-thirds of the length of the 

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

 from the eyes. Head and thorax minutely and closely punctured, 

 the front clothed with short, silvery pubescence. Head broader 

 than the thorax ; the pronotum short but not linear, strongly 

 depressed anteriorly. Mesopleurse rather more strongly punctured
