Type ( d" ) in C. French's collection; type (9), I. 5690, in 

 South Australian Museum. 



Much larger than any previously described species of the 

 genus; each of the three basal joints of the male tarsi has on 

 each side of its apex an acute spine, and these may eventually 

 be considered as of generic importance. The head, prothorax, 

 and scutellum are darker (almost black) than the rest of the 

 body, but no part is of a bright colour. The femora of the- 

 male are without distinctively sexual clothing. The eleventh 

 joint of antennae is narrowed from about the apical fourth, 

 the narrow portion appearing to start from a feeble suture. 

 The antennae of the female are probably shorter than those- 

 of the male, but on the only one before me they are broken 

 off almost at the base. The two males differ somewhat, the 

 (smaller) one from Western Australia having stouter 

 antennae, the outer line of each mandible an almost even 

 curve (on the type the polished apical portion is deflected 

 almost at a right angle), the apical segment of its abdomen 

 is more strongly concave (probably due to irregularity in 

 drying), and the tarsal spines are less conspicuous. 



Uracanthus insignis, n. sp. 

 PI. xxxii., fig. 5. 



Dark piceo-castaneous, elytra (apex and suture excepted) 

 paler. Densely clothed (except for some conspicuously 

 glabrous spaces) with short stramineous and white pubescence. 



Head with muzzle almost twice as long as wide; clypeus 

 with a few conspicuous punctures, rounded posteriorly, with 

 the suture deep, triangular, and wide in the middle. 

 Antennae thin, not passing third abdominal segment, fifth 

 to tenth joints rather feebly produced to one side at apex, 

 tenth about two-thirds the length of eleventh. Prothorax 

 much longer than wide, base almost twice as wide as apex: 

 glabrous portion with about twenty conspicuous corrugations, 

 but irregular and with a small node on each side of middle. 

 Elytra narrow, almost parallel-sided, each widely emarginate 

 and strongly and acutely bispinose at apex, with remnants of 

 feebly-elevated lines ; with dense and minute punctures, but 

 on basal third with rather large partially-concealed ones. 

 Legs thin, but not very long. Length, 30 mm.

 Type, I. 5691. 



The most beautiful species of the genus, with an 

 unusually long muzzle, curious clypeal suture, and apical 

 spines of elytra unusually far apart. The type is probably a 

 male, although the femora are without distinctively sexual 

 clothing. The clothing on the head is rather dense, but the-
