joints of the palpi gradually dilated and compressed to the apex, and broadly trun- 

 cated, the labials more strongly so, with bisetose penultimate joint. Mandibles 

 furnished with a setigerous pore. Thorax suborbicular, as wide as the elytra, the 

 latter without scutellar stride. Joints 1 — 3 of the anterior tarsi, with their outer 

 angles produced, in the ^ more strongly so, and their soles on the inner side fur- 

 nished with a rounded pad of compact hairs. 



The genus is nearest allied to Lychnus (Putz.), but clearly distinct 

 by the form of the anterior tarsal joints, and the clothing of the 

 soles in the ^ .

Shining pitchy-black, the palpi, antennoe, and legs dark red. The transverse 

 occipital groove punctured, the rest smooth. The thorax strongly rounded on the 

 sides, but a little narrower at the base than between the prominent but rounded 

 anterior angles, and suddenly narrowed close to the base, whereby the hind angles 

 become slightly projecting ; the base with a few large punctures, the dorsal furrow 

 deep, the rest smooth. Elytra towards the suture sharply striated, the exterior 

 strisB and all striee near the apex obsolete. Long., 13 mm., <? ? .

 nau. Trans. R, S. Victoria (2), vol. viii, p. 161. 

 This species, of which Mr. Olliff has sent me a single (apparently female) 

 example, certainly cannot remain in the genus to which M. Putzeys has referred it. 

 The head is of entirely different form, strangulated (though not so strongly as in 

 Lychnus) immediately behind the eyes, the neck not broader than the anterior part, 

 the eyes prominent, the frontal furrows deep and lateral, and the mandibles short 

 and broad, and abruptly falcate at the tip. As in the Broscidce generally, it has 

 only one supra-orbital pore, whereas Percosoma has four in line close together. 

 The first three joints of the anterior tarsi are greatly prolonged at their outer apices, 

 and the palpi dilated and transversely truncated, the labials subsecuriform. If the 

 male prove to have the soles of the dilated joints of the anterior tarsi furnished with 

 a hair-pad, the species will belong to Eurylychnus, from which it differs only in the 

 elytra having a scutellar striole.

Neither of the above-cited descriptions of this fine species is satisfactory ; 

 C'haudoir'g minute details of the elytral sculpture do not agree with any of the ten 

 examples, males and females, which I have examined, and which include specimens 

 named by Macleay himself. The species is distinguished from Q. titana, longU 

 pennis, Bostocki, and others, by the rotundity of the sides of the thorax continuing to 

 behind the middle, by the sub-opaque elytra, and by the broad lobular production
