84 SUBFAMILIES CYPHALEINjE AND CNODALONINjE, 



straight, forehead vertical, eyes half concealed by prothorax, 

 separated by a distance equal to the transverse diameter of one 

 eye; antennae reaching the base of prothorax, joints 3-5 short and 

 slender, 7-11 moderately enlarged, 8-10 somewhat round, about 

 as wide as long, 11 ovate, longer and wider than 10. Prothorax 

 2J x 4 mm., convex, feebly arcuate-emarginate at apex: anterior 

 angles scarcely produced, deflexed and obtuse, the sides feebly 

 rounded anteriorly, nearly straight behind; posterior angles sub- 

 rectangular, widest at base, lateral border and channel very 

 narrow, apical border still narrower, disc without any lateral 

 foliation, and, like the head, densely and evenly punctate. Scu- 

 tellum transversely triangular, nearly smooth. Elytra slightly 

 wider than prothorax at base, moderately convex, scarcely 

 parallel, sides narrowly bordered and channelled throughout, 

 disc closely and irregularly punctate (very much as in 0. tenui- 

 tarsis Pasc). Abdomen with two apical segments minutely 

 punctate, other segments striolate, intercoxal process triangular; 

 metasternum coarsely punctate; prosternum rugose, widely cari- 

 nate, its process received into a V-shaped notch of the meso- 

 sternum; legs and tarsi rather short, claw-joint of posterior tarsi 

 scarcely longer than the basal joint. Dimensions, 9|-11 x 4-5 mm. 



Hob. — Tambourine Mountain, South Queensland. 



Two specimens, taken by Mr. A. M. Lea and the author 

 respectively, in January, 1912, can be readily distinguished from 

 Olisthcena by their convex prothorax, with its wide and bent 

 down anterior angles, the disc continuous to the lateral channel, 

 less parallel form, etc. Type in the author's Coll. 



Toreuma, n.gen. 



Elongate, subparallel, eyes large, rather close. Epistoma 

 short and tumid, canthus little raised and rounded in front; 

 antennae short and very fine, penultimate joints not much 

 enlarged, last joint of maxillary palpi small, securiform, of the 

 labial obconic, prothorax moderately convex, explanate laterally, 

 sides arcuately narrowed from base to apex, strongly emarginate 

 at apex, elytra strongly arched longitudinally, gibbous near the
