470 MR. R. E. TURNER ON [May 12, 



Black ; the base of the mandibles, clypeus, front as high as the 

 base of the antennae, the frontal carina, the sides of the pronotum, 

 the postscutellum, a large spot on each side occupying the whole 

 length of the median segment, the sides and apex of the first 

 abdominal segment, the second segment except a triangular mark 

 at the base, the apex of the fifth segment very broadly, and the 

 two basal ventral segments yellow ; the antennfe, the outei' orbits 

 of the eyes connected with a broad l^and on the posterior margin 

 of the head, a large spot on each side occupying the greater 

 part of the mesonotum, the scutellum, the apex of the fifth ventral 

 segment, and the legs dull ferruginous ; the coxfe above black. 

 Wings pale flavo-hyaline, nervures light testaceous, a faint cloud 

 in the radial cell. 



Length 14 mm., exj). 24 mm. 



Hob. Mackay, Queensland [Turner); November. 



Cerceris labeculata, sp. n. 



2 . Mandibles simple, blunt at the apex. The central lol^e of 

 the clypeus slightly convex and feebly porrected at the apex, 

 narrowly emarginate anteriorly, the angles of the emargination 

 produced into short teeth, narrowly truncate at the base, the 

 length almost as great as the greatest breadth. Antennte inserted 

 high up on the front, nearei' to each other than to the eyes, from 

 which they are separated by a distance less than the length of the 

 scape, which is short ; the second and third joints of the flagellum 

 nearly equal in length. The antenna? are separated from the 

 base of the clypeus by a distance equal to two-thirds of the length 

 of the clypeus. Inner margin of the eyes parallel ; the posterior 

 ocelli nearly as far from each other as from the eyes and nearer 

 to the posterior margin of the head than to each other. Front 

 sparsely and shallowly punctured, the carina between the antenna 

 not very strongly raised ; vertex, mesonotum, mesojDleurje, and 

 sides of the median segment coarsely punctured-rugose. Pro- 

 notum strongly rounded at the angles ; the triangular space at 

 the base of the median segment finely obliquely striated. First 

 abdominal segment longer than broad, depressed at the base ; the 

 abdomen deeply and closely punctured ; the pygidial area finely 

 punctured, narrowly truncate at the apex, where it is only half 

 as wide as at the base, rather broader in the middle than at the 

 base. 



Black ; the mandibles at the base, the clypeus except the base 

 and the extreme apical margin, the apex of the interantennal 

 carina, the inner orbits of the eyes as high as the base of the 

 antenn* very broadly, and the scape of the antennae pale yellow ; 

 the posterior margin of the pronotum interrupted in the middle, 

 the postscutellum, the apical margin of the first, second, and 

 fourth abdominal segments, and a short vertical streak on the 

 mesopleura?, orange-yellow; the flagellum. tegula?. scutellum, first 

 abdominal segment, the middle of the second, the apex of the 

 fifth, the pygidium, and the legs (except the cox?e, trochanters,
