punctiform fovea on upturned edge of segment, just above each 

 posterior setigerous puncture. Anterior femora without a sub- 

 apical seta on posterior face; posterior coxa with a setigerous 

 puncture; posterior trochanters inipunctate. Length, 19-5; 

 breadth, 435 nmi. 



Hab. — Northern Territory: Katherine River. Coll. French 

 (unique). The type is now in the National Museum, Melbourne. 

 Mr. F. P. Dodd afterwards sent me a specimen (9) from Port 

 Darwin. 



In facies, this remarkable species resembles a species of Tera- 

 tidium, but is at once distinguished from that genus by having 

 the anterior tibise bidentate. It is allied to C. aberrans SI., 

 from which it differs by ^ with head larger, less strongly nar- 

 rowed l^ehind eyes, posterior parts of orbits and eyes less pro- 

 minent, paragense much more developed, right mandible with 

 upper side near base I'aised into a strong wide prominence, labrum 

 and median part of clypeus emarginate; prothorax shorter, border 

 narrower, less advanced at anterior angles, lateral marginal 

 channel not forming a sulciform gutter and without any marginal 

 setfe; elytra more widely rounded at apex, etc. 



TeuATIDIUM ROBUSTUiM, n.Sp. 



Elongate, convex, laivigate. Head as wide as prothorax, eyes 

 protuberant, frontal sulci long, deep; prothorax as broad as long, 

 widest before middle, rounded on sides; elytra elongate-oval, 

 impunctate; anterior tibise unidentate at apex. Black, nitid. 



Head large (5 ram. across e3"es), convex, roundly declivous to 

 anterior margin, strongly declivous to eyes; clypeus trisinuate 

 behind labrum, intermediate angles short, obtus-e; three setiger- 

 ous supraorbital punctures on each side placed very close together 

 near posterior margin of eye; eyes deeply set in orbits, convex, 

 prominent ; orbits narrow behind eyes, rising sharply but 

 roundly from neck; submentum plurisetose on each side. Pro- 

 thorax of same width as head with eyes (5 x 5 mm.), strongly 

 angustate to base; disc subdepressed; sides lightly rounded; 

 posterior angles not marked; basal curve strongly sinuate on 

 each side; base forming a wide rounded lobe; anterior margin
