latiore, subtilissimo punctulato ; elytris lineatira impresso-punc- 

 tatis; femoribus muticis, haud canaliculars. Long. 3|-4| lin. 



Hob. Port Bowen. 



A remarkably broad species, the breadth of the elytra 

 exceeding their length. The first abdominal suture is not 

 traceable, or rather is replaced by a large, deep, irregular 

 impression. 



iETHREUS. 



Caput rotundatum ; rostrum rectum, subulatum, basi excepta nudum; 

 scrohes subbasales ad partem inferiorem oculi desinentes. Oculi 

 antice approximati, tenuiter granulati. Srajnis brevis; funiculus 

 articulis duobus basalibus elongatis,tertius usque ad septimum gra- 

 datim brevioribus et crassioribus ; clava distincta, breviter ovata. 

 Proilwrax transversus, dorso planatus, lateribus verticalis, apice 

 haud productus, basi bisinuatus, lobis ocularibus fere obsoletis. 

 ScuteUum distinctum. Elytra oblongo-subcordata, supra depressa, 

 prothorace latiora, apicibus rotundata. Mima pectoralis in meso- 

 sterno mitraeformi terminata, apice cavernosa. Pedes mediocres ; 

 femora modice elongata, mutica ; tibia; subcylindricac, recta?, vel 

 intus paulo bisinuatae. apice extus spina recta instructae ; tarsi 

 articulo tertio ampliato, profunde bilobo ; unguiculi subdivergentes. 

 Abdomen segmentis duobus basalibus majoribus, sutura prima 

 arcuata. 



An isolated form, which I can only suggest may be found 

 to have Memos and Mitrastethus as remote allies. To these 

 genera it is approximated by its straight rostrum, short scape, 

 general character of the underparts, except that the meta- 

 thoracic episterna are rather narrow ; and to Mitrastethus 

 somewhat in outline, but not otherwise. The peculiar arma- 

 ture of the tibiae may belong possibly to only one sex. The 

 elytra of the only exponent of this genus are marked with 

 brown lines, caused by the dark approximate punctures in the 

 sulci, and each elytron has a brown oblong spot, to the naked 

 eye apparently depressed or contracted like a scar. I am in- 

 debted for my specimen to Mr. Masters. 



JEthreus cicatricosus. PI. I. fig. 8. 



A2. ellipticus, fuscus, supra sat dense, infra pedibusque densissime 

 griseo-squamosus ; rostro nitide piceo, prothorace multo breviore ; 

 antennis ferrugineis ; prothorace apice valde angusto, squamis 

 rotundatis paulo sejunctim tecto ; elytris sulcato-punctatis, punctis 

 approximatis, interstitiis paulo convexis, quinto sextoque in medio 

 macula oblonga fusca notatis, apicem versus paulo prominulis.
