In this species the head is but little covered by the thorax. 

 The lateral grooves of the rostrum are oblique, and the mandibles 

 of the male are produced downwards and backwards from the 

 outer angles into a somewhat acute horn. The thorax is narrow, 

 and is thickly and rather finely tuberculated, while the medial 

 dorsal line is almost obsolete. The elytra are costate, the 

 alternate " costee " being larger, while the intervals have a some- 

 what reticulated appearance. The anal appendage of the male is 

 long, but not quite so strong as in the species already described. 



I have never seen this insect, except in the late Mr. MacLeay's 

 collection, where there are several specimens, and as one of them 

 was labelled Swan River, I take it for granted that they are all 

 from Western Australia. 



6. — PSALIDURA MIRACULA. 



Oblongo-elliptica nigra nigro-setosa parce squamosa, fronte 

 medio vittata, thorace tuberculato antice leviter lobato 

 postice medio canaliculato, elytris elongatis tricostatis 

 interstitiis reticulatis lateribus rugosis subcostatis apic€ 

 remote mucronatis. 

 Mas ; mandibularum angulis externis longissime acute pro- 

 ductis, forfice anali longissimo acuto. 

 Long. 11 lin., lat. 4| lin. 

 Hab. Mudgee. 



The extreme length of the horns of the mandibles, which are 

 also sharp and sickle-shaped, is the most remarkable charac- 

 teristic of this species. The anal forceps is also of great length. 

 In other respects it is not unlike P. mira, it is, however, longer, 

 more coarsely tuberculated on the thorax, and more regularly 

 reticulated on the elytra than that species. 



The only specimen I know was taken by Mr. Masters last 

 summer, near Mudgee, and is now in the Museum,
