the sides and apex very finely punctured. Abdomen subovate, 

 scarcely longer than the thorax and median segment combined, 

 the second segment the broadest, the apical segment lanceolate. 

 The first recurrent nei-vvu-e is received by the first cubital cell a 

 little before the apex, the second is interstitial with the second 

 transverse cubital nervure. The second cubital cell is scarcely 

 moi-e than half the length of the third, the first is longer than the 

 second and thml combined. The second on the radial nervure is 

 a little more than half as long as on the cubital. 



Black ; the clypeus, the scape of the antennae, a large spot on 

 the mesopleurse beneath the anterior wings, the scutellum, post- 

 scutellum, and a spot on each side near the apical angles of the 

 second abdominal segment yellow. The tarsi and anterior tibiae 

 fuscous. Wings hyaline, nervui-es fusco-ferruginous. 



Length 8 mm., exp. 13 mm. 



Hah. Mackay, Queensland {Turner') ; October. 



The intermediate tibiae have two spines at the apex ; the tarsal 

 ungues are long, curved, and simple. The form is very similar to 

 sanguinolentus^ but the scutellum is shorter and the whole insect 

 less robust. 



A colour variety from Cairns is without the yellow spot on the 

 second abdominal segment and has the apical half of the clypeus 

 dark brown.

$ . Clypeus broadly truncate at the apex, subtriangular, but 

 truncate at the base, almost smooth. Eyes very large, diverging 

 towai'ds the vertex, approaching each other most closely at the 

 base of the clypeus, where they are separated by a distance about 

 equal to the length of the scape of the antenna. Antennae 

 inserted rather high up on the front, as near to the eyes as to 

 each other ; the seconcl joint of the flagellum nearly half as long 

 again as the third and quite as long as the scape, the four or five 

 apical joints forming a strong club, the joints broader than long. 

 The posterior ocelli far apart, two and a half times as far from 

 •each other as from the eyes, from which they are separated by a 

 distance equal to the length of the first joint of the flagellum. 

 Head opaque, the space round the ocelli rather coarsely punctured. 

 Thorax and median segment closely punctured ; the pronotum 

 depressed below the level of the mesonotum, the posterior angles 

 widely separated from the tegulfe. Median segmeiit as long as 

 the mesonotum, truncate at the apex, with a longitudinal carina 

 on the surface of the truncation, the triangular area at the base 

 of the segment rather obscui-ely defined and very finely rugose. 

 Abdomen petiolate, the first segment half as broad again at the 

 apex as at the base, and nearly twice as long as the breadth at 

 the apex ; second and third segments large and broad ; the whole 

 abdomen rather closely punctured and opaque ; the apical margin 

 of the first segment smooth and shining, with sparse punctures. 

 Pygidial area triangular, with the margins slightly raised, covered
