of the suture near the apex is an elongate narrow stripe. Meso-, 

 middle and sides of metasternum and abdominal segments, and 

 base of aculeus with obscure pubescence. 



Aculeus moderately long, broad at the base, strongly lessened 

 from there to beyond the middle, then narrow, apex pointed. 

 Posterior spurs unequal, longest about two-fifths the length of the 

 first tarsal joint. Length 3|-5, width lf-1 J mm. 



Ilab. — Forest Reefs. 



The markings of the elytra are suflicient to render this species 

 easy of identification; at first sight it resembles 21. limhata, than 

 which it is slightly broader. 



MoRDELLA COMMUNIS, Waterh.; Mast. Cat. Sp. No. 4317. 



From New South Wales I have numerous specimens which 

 agree in all particulars with the descriptions of this species; they 

 are all dingy, many of them having a greasy look, caused by a 

 sprinkling of gre3dsh pubescence; the elytral macule are often 

 obsolete, and they are never very clearly defined. 



MoRDELLA FELIX, Waterh.; Mast. Cat. Sp. No. 4321. 



I have this species from Blackheath (Masters), and Forest 



Reefs (Lea). Mr. Waterhouse in describing ' it says: — "Head 



with a distinct longitudinal hnpressed line";' this should 



read " pubescence i^artecl in the middle," a character common to 



most species; very few have an impressed line. 



MoRDELLA TRiviALis, Waterh.; Mast. Cat. Sp. No. 4334. 



I have two specimens — one from Galston and the other from 

 Newcastle — which agree ver}^ well with Mr. Waterhouse's des- 

 cription of this species; he omits to mention the colour of the 

 posterior spurs; in my specimens they are piceous-black; in the 

 Newcastle specimen the anterior femora are reddish-testaceous, 

 the intermediate somewhat darker; in the Galston sj^ecimen all 

 the le^'s are concolorous.
