SCITOX. 



For the original diagnosis (P. L. S., N.S.W., 1892, p. 101) it 

 will be well to substitute the following fuller one. 

 Clypeus aatice truncatus, lateribus sinuatis ; mentum antice 

 emarginatum, lateribus pone apicem profunde excisis ; palpi 

 labiales modici, articulo ultimo dilatato ; palpi maxillares 

 parum elongati, articulis robustis (apicali 2° longitudine 

 fequali quam 3"^^ sat longiori) ; labrum vix exsertum, antice 

 (superne viso) truncatum vel late vix emarginatum ; oculi 

 magni nitidi vix manifeste granulati, antice a cantho pro- 

 funde incisi ; antennae (specierum cognitarum) O-articulatse, 

 clava 3 - articulata (hac maris * cogniti quam articuli 

 prsecedentes 5 conjuncti pauUo longiori, feminse paullo 

 breviori) ; prothorax transversus ; elytra geminato-striata ; 

 tibiae anticae extus tridentatae, posticis fere ut Sericesthis 

 (elongatis, gracilibus, intus fere rectis) ; unguiculi simplices ; 

 sterna pilis erectis sat brevibus minus perspicuis vestita, 

 pedibus sparsim pilosis. 

 A very distinct genus on account of the form of the clypeus 

 (recalling that of Mcechidius), the peculiar excision of the sides 

 of the mentum disclosing the extreme base of the labial palpi, 

 and the scarcely exserted labrum resembling that of the genus 

 I take to be Ocnodus. 



S. pauUuSj sp. nov. Ovatus, minus elongatus ; subopacus, non- 



nihil pruinosus ; supra glaber ; rufo-ferrugineus, antennis 



palpisque testaceis ; clypeo nitido in medio subgibbo crebre 



squamose, capite postice prothoraceque vix manifeste, elytris 



parum distincte, pygidio nitido subtiliter sat crebre, punctu- 



latis ; prothorace sat transverso, antice minus angustato, 



lateribus leviter arcuatis, basi utrinque leviter sinuata, 



angulis anticis acutis minus prominulis posticis superne visis 



sat (nee acute) rectis ; elytris geminato-striatis, interstitiis 



alternis angustioribus subconvexis ; tarsorum posticorum 



articulo basali quam 2*"^ paullo longiori. Long., 5 — 5f 1. ; 



lat. 24—3 1. 



Very much like S. ruber, Blackb., but much smaller, and easily 



distinguished inter alia by its clypeus being quite gibbous in the 



middle longitudinally (so that from a certain point of view it 



appears foveate on either side) and by the notably longer basal
