Though like the last five species this is altogether a larger 

 and rougher insect. The third scries of tubercles from the suture 

 consists in both the specimens before me, of three tubercles on the 

 right elytron and two on the left. There is also visible on one of the 

 specimens an anal appendage, which seems like a thin coriaceous 

 forceps with a membi-anaceous covering. I have observed some- 

 thing of the same kind in the dissection of other species, and it is 

 very conspicuous in Psalidura tristls Boisd. — which insect I place 

 in the genus Sderorinus. The points at the apex of each elytron 

 ai'e close together in this species ; in all the previously described 

 species of this section the elytra are more or less dehiscent. 



The two specimens I have seen (both males) are in the col- 

 lection of the late Mr. MacLeay, and are labelled "New Holland."

The specimen from which the description is taken is a female. 

 The sculpture of the elytra is much more rugged and deeply 

 rugose than in any of the previous species, the tubercles not
