differs in the absence of a longitudinal depression on tlie 

 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 metallica is from Adelaide, but 

 the species ranges as far west as Perth. 



Ephutomorpha dilecta, sp. n. 



$ . Cserulea, abdomine viridi-seueo ; antennis mandibulisque nigris ; 



pedibus fuscis, femoribus intermediis posticisque basi, tibiisque 



posticis supra ferrugiueis. 

 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 the 

 mandibles ; antenual tubercles well developed ; 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 apex, 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 the apical 

 segments clothed with long black hairs. Intermediate and 

 hind tibijB with one well-developed spine near the middle of 

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

 two spines nearly as long as the 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 

 amoina, Andrd, and other metallic species from North 

 Queensland.
