 rostrum, 1| mm. ; width, 3 mm. ; variation in length,

Hab. — Queensland: Cairns (Macleay Museum). . 



Appears to be an abundant species, judging by the num- 

 ber of specimens in the Macleay Museum. It is abundantly 

 distinct from nodipennis and araneus by the shape of the 

 mesosternal receptacle and the strong (although concealed) 

 prothOracic punctures ; in shape it is intermediate. The 

 clothing is much denser, and of a slightly different shade of 

 colour to that of araneus. 



This species agrees fairly well with Mr. Pascoe's descrip- 

 tion of odiosus, except that the elytra are not callose towards 

 the base, and that the punctures are not distinct, being in fact 

 closer together than usual. But if the locality given for 

 odiosus (King George Sound) is correct (a subject, however, 

 that appears to me to be doubtful judging by the distribu- 

 tion of Onidistus and its allies) there should be no liability 

 to confound the two species. 



PSEUDONIDISTUS, n. g. 



Head partially concealed, forehead trisinuate. Eyes 

 large, ovate, moderately faceted. Rostrum moderately 

 long and rather thin, each side with a shallow 

 groove above the scrobe. Antennae thin ; scape in- 

 serted nearer apex than base of rostrum, longer than 

 funicle ; two basal joints of funicle elongate ; club ovate, 

 moderately large. Prothorax transverse, base bisinuate, sides 

 rounded, apex feebly produced, constriction slight, ocular 

 lobes obtuse. Scutellum not traceable. Elytra cordate. 

 Pectoral canal rather shallow and not very wide, wider 

 between coxae than in front, terminated between intermediate 

 coxae. Mesosternal receptacle transverse, sides produced, 

 hinder margin semicircular; open. Metasternum much 

 shorter than the following segment ; episterna narrow but 

 distinct throughout. Abdomen moderately large, sutures 

 distinct, first segment as long as the two following combined, 

 intercoxal process wide ; third and fourth combined slightly 

 longer than second and considerably longer than fifth. Legs 

 long ; posterior coxae touching elytra ; femora stout, sub- 

 pedunculate, acutely dentate, not grooved, posterior passing 

 elytra; tibiae somewhat compressed, thin, bisinuate beneath;
