OF NEW SOUTH WALES. 215 



are black, the remainder of the upper surface is of a golden green 

 and very nitid, and the under surface is black with a tendency to 

 piceous on the tarsi, antennas, and palpi. The head is large and 

 rather flat, the facial grooves are deep and diverge much behind, 

 and the labrum is short, broad, crescent-shaped, and marked in 

 front with six setigerous punctures. The thorax is slightly 

 broader than the head, and much broader than long, broadly 

 rounded at the sides and posterior angles, and truncate at the 

 middle of the base, the median line is lightly marked, and the 

 depressions near the posterior angles are rounded and shallow. 

 The elytra are of an elongated oval form, scarcely so wide as the 

 widest part of the thorax, and marked with seven shallow 

 punctured stria?, and with a row of sub-distant larger punctures 

 in each lateral margin. At the base of each elytron there is a 

 depression marked with seven punctures in two obliquely transverse 

 series — five in one and two in the other. The legs are rather 

 slight for the genus. The fore tibiae are armed externally with 

 two strong teeth, the intermediate tibiae are without external 

 spine. 



I have named this handsome species after the very excellent 

 collector who discovered it — Mr. Edward Spalding. 



Coronacanthus. New genus. 



Mentum three lobed, the middle one shorter than the two others 

 and bilobed at the apex, the sides of the lateral lobes converging 

 towards the base. 



Palpi, rather elongate — the maxillary with the terminal joint 

 truncate, slightly trigonal, and of the same size as the third — 

 the labial with the terminal joint truncate and trigonal. 



Mandibles, rather short and stout, and slightly toothed in the 

 middle. 



Labrum as in Feronia. 



Antennae, of moderate length, slender and filiform ; the third 

 joint very slightly longer than the others. 

 Labrum square ; slightly emarginate in front.
