INSECT FAUNA. 91 



*Orthorriitnus lateralis, JPasc. 



Orthorrhinus lateralis, Pascoe, Ann. Mag. Nat. Hist., (5) IX, p. 381 (1882). 



Evidently not uncommon, as it occurs in most of the collections I have 

 seen from the island. 



*Orthorrhixls vagus, sp. nov. 



Sub -cylindrical, piceous, thickly covered with ashy gray and ochraceous 

 scales ; prothorax moderately strongly tuberculate, with two erect fascicles 

 in front ; elytra with irregular rows of tubercles, and three discal tufts. 



Head covered with ochraceous scales ; rostrum nearly straight, decidedly 

 longer than the prothorax, finely and rather closely punctured. Antennae 

 moderately long ; the funiculus with the first joint almost as long as the four 

 succeeding ones together, the second joint elongate, the third to sixth about 

 as broad as long. Prothorax rather longer than broad, strongly constricted 

 in front, the tubercles inconspicuous near the anterior margin, the two 

 marginal tufts composed of erect pubescence and scales. Scutelluin trans- 

 verse, rounded behind, thickly covered w 7 ith scales. Elytra considerably 

 more than twice as long as the prothorax, parallel-sided, with rows of 

 impressed punctures between irregular series of tubercles, those in the 

 middle being the most conspicuous : each elytron with a small tufted eminence 

 near the base, a large tuft behind the middle, and a third on the preapical 

 callus, which is not very prominent. Underside thickly clothed with och- 

 raceous and scattered dusky-white scales. Legs with the tibiae bisinuate 

 internally. Length, 11 — 13 mm. 



This species, which is also found at Kiama, in the Illawarra district of New 

 South Wales, evidently belongs to the O. cylindrirostris group of the genus 

 Orthorrhinus. The antennae are inserted at rather more than a third of the 

 length of the rostrum from the apex, and the basal half of the elytra is, in 

 most specimens, decidedly lighter in colour than the apex, owing to the 

 preponderance of the gray scales. 



Traces ixsllaris, Pasc. 



Tranes insularis, Pascoe, Ann. Mag. Nat, Hist., (4) XIII, p. 387 (1874). 



Summit of Mount Ledgbird (2,500 feet) ; also found on the low-lying 

 lands. It appears to be an uncommon species. 



Belus acrobeles, sp. nov. 

 Plate YI, f. 2. 



Elongate, fuscous, somew T hat shining, sparingly clothed with fine gray 

 pubescence ; rostrum ferruginous and smooth beyond the point of insertion 

 of the antennae ; prothorax finely rugose, the sides and. the median line 

 clothed with ochraceous pubescence. 



Head moderately strongly punctured between the eyes, which are large and 

 prominent, finely punctured at the base ; rostrum roughly punctured at the 

 base. Antennas ferruginous, the second joint about half as long as the first, 

 the third and fourth a little shorter than the first, fifth to tenth somewhat 

 thickened, gradually increasing in length, the apical joint pointed at the 

 extremity. Prothorax considerably narrowed and somewhat constricted in 

 front, slightly impressed on each side in the middle, the median line distinct, 

 sparingly clothed with fine ochraceous pubescence ; the sides thickly clothed 

 with ochraceous pubescence. Scutellum broadly transverse. Elytra strongly 

 produced posteriorly, somewhat flattened on the disc, strongly punctured, 

 the punctures arranged in rows near the suture, rugulose near the sides.
