and base of the femoi-a) ferruginous. Wings hyaline, stained 

 with fuscous along the costa, nervures black. 



(5 . As in the female, but the clypeus is rather longer and not 

 porrect at the apex, and the apical half of the fifth abdominal 

 segment is yellow. 



Length, $ 9 mm., cS 8 mm. 



JIab. Cairns, Queensland [Turner) ; December and January. 



Somewhat related to C. antipodes Sm., but the head is much 

 narrower and it is a much smaller species. The clypeus is also 

 very different. 



Cerceris multiguttata , sp. n. 



2 . Clypeus more than twice as broad as long on the central 

 lobe, short, slightly porrect at the apex, the apical margin very 

 slightly and broadly emarginate, with four minute teeth. Antennae 

 inserted nearer to each other than to the eyes, separated from the 

 eyes by a distance equal to three-quarters of the length of the 

 scape and about the same distance from the base of the clypeus ; 

 the second joint of the flagellum twice as long as the first and 

 half as long again as the third. The inner orbits of the eyes 

 very nearly parallel ; the posterior ocelli a little further from the 

 eyes than from each other, and about the same distance from the 

 posterior margin of the head as from each other. Head, thorax, 

 and median segment coarsely and closely punctured, the frontal 

 carina strongly i-aised between the antenna?. Pronotum broadly 

 rounded anteriorly ; scutellum very broadly truncate at the apex. 

 Median segment with a shallow sulcus from the base to the apex, 

 the triangular space at the base smooth and shining. Abdomen 

 coarsely punctured, the fourth and fifth more shallowly than the 

 basal segments ; the first segment broader in the middle than 

 long, slightly nari-owed to the base and apex and obliquely de- 

 pressed at the base, not as long as the second segment. Pygidial 

 area finely rugose, twice as long as broad, the sides nearly parallel, 

 broadly rounded at the apex. 



Black ; the mandibles at the base, clypeus, outer orbits of the 

 eyes, the inner orbits broadly to a little above the base of the 

 antennse, a narrow line from the anterior ocellus to the base of 

 the clypeus, an oblique spot on each side of the vertex, the pro- 

 notum narrowly interrupted in the middle, the tegula?, a spot on 

 the mesopleurse, a large round spot on each side of the scutellum, 

 the postscutellum, a small spot on each side on the triangular 

 space at the base of the median segment, a large spot on each side 

 at the apex extending on to the sides, the first abdominal segment 

 except at the base, the apical half of the second segment, the 

 three apical abdominal segments (narrowly black at the base), the 

 tibife, tarsi, and the apex of the femora all dull brownish yellow. 

 Wings hyaline, tinged with fulvous, darker on the costa ; nervures 

 ferruginous.
