238 ON THE AUSTRALIAN CLIVINIDES, 



acuminate; intermediate tibiae with outer edge spinulose, the 

 external spur prominent and placed considerably before the apex. 



Length 9, breadth 2-5 mm. 



Hah. : Queensland — Port Darwin, Roper River (sent by Mr. 

 Masters). 



A very distinct species, in general appearance much resembling 

 a small species of Promecoderus. Its affinity is to C. ahbreviata, 

 Putz., but it differs greatly from that species by its smaller size; 

 head much wider in front of eyes, more strongly rounded (a 

 strong sinuosity behind wings of clypeus) to anterior angles, the 

 facial carinas long, incurved, forming a border to the inner side 

 of the supra-antennal plates, eyes more deeply enclosed in orbits, 

 these more abruptly constricted behind; prothorax more quadrate, 

 the sides sinuate, the basal curve still shorter; prosternum with 

 intercoxal part not bisulcate, &c. 



Clivina regularis, n.sp. 



Robust, parallel. Head as in C. procera; clypeus deeply 

 emarginate-truncate; prothorax as long as broad, lightly narrowed 

 anteriorly; elytra parallel, simply striate, striae deep on disc, weak 

 on sides, interstices convex on disc, eighth feebly indicated near 

 apex, submarginal humeral carina short; prosternum with inter- 

 coxal part very wide anteriorly, episterna smooth; lateral cavities 

 of peduncle deep, not punctate; metasternal episterna of medium 

 length; metasternum between anterior and posterior coxaj not 

 longer than posterior coxae; anterior tibiae 3-dentate. Black. 



Head smooth, large (2 x 2-2 mm.), convex, obliquely angustate 

 before eyes; lateral impressions light; clypeal elevation convex : 

 clypeus divided from front on sides, depressed along anterior 

 margin; median part truncate; wings concave, strongly advanced, 

 obtusely rounded at apex; eyes prominent, convex, enclosed by 

 orbits. Prothorax as long as broad (2-9 mm. x 2-9 mm.), lightly 

 nari'owed anteriorly (ant. width 2*4 mm.), smooth, convex; sides 

 nearly straight, obsoletely sinuate; posterior angles rounded, not 

 marked; anterior margin widely and very lightly emarginate; 

 anterior angles obtuse, but slightly prominent; median and
