differs in the absence of a longitudinal depression on the 

 basal half of the second dorsal segment, in the greater 

 breadth of the thorax, which is more than twice as long as 

 the greatest breadth in metallica, and in the greater length 

 of the second dorsal segment. The colour of the thorax is 

 also different. The type of nietallicn is from Adelaide, but 

 the species ranges as far west as Perth.

2 . Ca?rulea, abdomiuc viridi-a^ueo ; an tennis mandibulisque nigris ; 

 pedibus fuscis, femoribus intermediis posticisque basi, tibiisque 

 posticis supra ferrugineis. 

 Long. 10 mm. 



? . Head no broader than the thorax, closely and not very 

 finely punctured, not narrowed behind the eyes, the posterior 

 angles very feebly rounded ; eyes large, a little nearer to 

 the posterior margin of the head tlian to the base of tiie 

 mandibles ; antennal tubercles well develoj)ed ; second joint 

 of the flagellum as long as the first and third combined. 

 Thorax nearly twice as long as the breadth on the almost 

 straight anterior margin, strongly narrowed from behind the 

 middle ; coarsely reticulate. Abdomen closely and finely 

 punctured; first segment oblique from near the apex to the 

 base, slightly constricted at the i\pex, with a spine on each 

 side at the base beneath ; second segment about half as long 

 again as the greatest breadth, not much broader in the 

 middle than at the apex, more strongly punctured than the 

 other segments, a small patch of white hairs at the apex of 

 segments 2-5. No pygidial area. The sides of tlie apical 

 segments clothed with long black hairs. Intermediate and 

 hind tibirc with one well-developed sj)ine near the middle of 

 the outer margin, the apex of the tibiae above produced into 

 two spines nearly as long as tlie calcaria, which are black.

In many points this is related to suhmetallescens, but 

 differs in the armature of the tibiae, in colour, and in the 

 shorter second abdominal segment. It is quite distinct from 

 amcvna, Andr($, and other metallic species from North 

 Queensland.
