The following species are unknown to me : — 



Melanterius piceirostris, Er.; I.e. No. 5398. Hah. — "Neu- 

 holland " (Erichson). 



Melanterius fugitivus, Pasc. ; I.e. No. 5397. Hah. — -"Swan 

 River " (Pascoe). 



NeO MELANTERIUS, n.g. 



Head small, not concealed; ocular fovea not traceable. Eyes 

 rather large, reniform, moderately close above, almost touching 

 below, coarsely faceted. Rostrum long and thin, feebly curved, 

 continued beyond mesosternum. Antejince slender; scape inserted 

 much closer to apex than base of rostrum; two basal joints of 

 funicle elongate; club small, ovate. Profliorax convex, trans- 

 verse, sides rounded, apex feebly produced and about half the 

 width of base, base bisinuate ; constriction feeble ; ocular lobes 

 obtuse. Scutellum round. Elytra subcordate, feebly convex, 

 considerably wider than and more than twice the length of pro- 

 thorax, shoulders and apex rounded. Pectoral eanal shallow, 

 narrow in front of anterior coxse, these feebly separated. Meso- 

 Hternal plate slightly lower than coxte, feebly transverse, not 

 concave. Metasterniim slightly shorter than basal segment of 

 abdomen; episterna of moderate size. Abdomen moderately large, 

 sutures distinct; 1st segment slightly longer than two following- 

 combined, truncate at apex, intercoxal process moderately rounded; 

 intermediates moderately large, their combined length greater 

 than that of 2nd or apical. Lec/s moderately long; femora stout, 

 clavate, not grooved, strongly dentate, posterior terminated 

 before apex of abdomen; tibiae compressed, rather thin, almost 

 straight, terminal hook moderately large; tarsi rather thin, 3rd 

 joint almost as long as wide, deeply bilobed ; claw-joint long, 

 increasing in width to apex; claws small, widely separated. Sub- 

 ovate, feebly convex, punctate, winged. 



The first species here described was sent to me by Mr. Masters 

 as Etcthehus troglodytes, which species it probably resembles to a 

 certain extent; but as Mr. Pascoe describes the rostrum of that 

 genus as being straight, the anterior legs as being the larger, the
