to spare a specimen for dissection, without which it is impossible 

 to be sure of all the structural characters, but I think there is no 

 doubt of its being closely allied to Paracijmus (Paranacama) 

 Lindi, Blackb., and sublineatus^ Blackb., of which it has quite 

 the facies, and the structural characters so far as I have been 

 able to examine them.

LACCOBIUS. 



The following species may, I think, be attributed to this genus 

 (not previously recorded as Australian so far as I know-), although 

 they differ from the European members of it in having maxillary 

 palpi somewhat more robust, the labrum shorter, the mesosternum 

 tuberculated (not sharply carinated) in front of the middle coxce, 

 and the tibiae set with short stiff erect bristles. In general ap- 

 pearance, sculpture, ifec, they resemble the European L. minutus^ 

 Linn., but are a little more elongate in form. The distinctive 

 characters mentioned above might justify a new generic name, 

 but I am satisfied that for the present it is better to minimise 

 genera, and so should be disposed to attribute to Laccobius all 

 species belonging to Ilydrohiides (Lacordaire), and having eight- 

 jointed antennae, tibiae devoid of swimming-hairs, prothorax and 

 ventral segments of the Hydrohius-ty^% and facies style of sculp- 

 ture, tfec, resembling the European Laccohii. Ilydatotrepltis 

 differs inter edict in having the last joint of the maxillary palpi 

 not longer than the penultimate, but in some characters comes 

 near Laccohius. 



L. montanus, sp. nov. Sat late ovalis ; sat nitidus ; brunneo- 

 piceus ; antennis (clava excepta), palpis (apice summo ex- 

 cepto), clypeo, prothorace, pedibusque dilutioribus vel tes- 

 taceis ; supra crebre jequaliter sat aspere punctulatus; elytris 

 leviter striatis ; prothorace fortiter transverso, antice fortiter 

 emarginato, lateribus sub-diaphanis, angulis omnibus rotun- 

 datis. Long., If 1. ; lat., f 1. 



The texture of the lateral portions of the prothorax is so thin 

 that these parts are transparent ; the prothorax is very much 

 wider across the l^ase than in front (though the hind angles are 

 so entirely rounded oft that there is no clear distinction between 

 the sides and the base ; the sides and apex of the elytra are paler 

 in colour than the disc. Compared with the European L. niinuiuSj 

 Linn., this species is throughout much more closely and evenly 

 punctured, the puncturation being moreover scarcely so strong as 

 that on the prothorax of L. tninutus.
