Femora iiotclied, and, subdentate underneath, ; tibiae nearly straight, 

 somewhat compressed, with well-developed terminal hooks, their inner 

 angles spiniform, the setae more slender than those on the elytra. Tarsi 

 hairy, 1st joint elongate, slender at the base, 2nd oblong yet shorter than 

 the basal one, 3rd short, moderately expanded and bilobed, the terminal 

 about as long as the basal, with simple claws. 



Underside shining, rufo-piceous, the sides of the breast with flavescent 

 scales or squamiform setae, abdomen with fine setae. Prosternum deeply 

 emarginate in front, rostral canal without sharply defined borders, be- 

 coming shallow between the coxae, and not extending into the mesosternum. 

 Mesosternal process broad, not concave, transversely rugose. Meta- 

 sternum rather short, punctate, with slender squamae at the sides. Basal 

 ventral segment as long as the metasternum, broadly medially impressed, 

 rather coarsely but not closely punctured, its apical suture extremely fine, 

 but deep at the sides, distinctly and broadly angulate between the coxae ; 

 2nd segment shorter, more distantly and finely punctate, transversely 

 impressed behind the middle. The sculpture of the prosternum seems to 

 consist of punctures and minute tubercles, which, however, owing to the 

 thick vestiture, are not easily seen. 



Female. — Rostrum as long as thorax, cylindric, rather slender, shining, 

 finely and distantly punctate. Antennae elongate, slender, and medially 

 inserted. 



Length (rostrum exclusive). 3^4| lines ; breadth, 1^-2^ lines.

Both sexes forwarded by Miss S. D. Shand. 



This cannot be Dr. Sharp's A. chathamensis, which is clothed above with 

 numerous erect setae only, whilst the thorax is described as " very rough, 

 with tubercular sculpture." 



Aldonus lineifer, sp. nov. 



Convex, oblong-oval, only slightly shining, fusco-piceous, antennae and 

 tarsi pitchy-red ; elytra very scantily clad with pale suberect squamae, 

 and short erect, pale and infuscate setae. 



Rostrum longitudinally rugose and punctate almost to the extremity, 

 and indefinitely carinate along the middle from its base to the point of the 

 antennal insertion. Thorax with moderately coarse punctures and more 

 or less distinct plane intervals, the sides more rugosely and closely punctate 

 but without discernible tubercles or granules, the mesial line smooth ; the 

 scales on the sides, in front, are oviform and depressed ; there are some 

 similar ones at the base, but on the disc they are slender and indistinct, 

 or altogether absent. Elytra coarsely striate-punctate, quite striate behind, 

 the punctures suboblong, distinctly separated, and encroaching on the 

 interstices in many parts ; the suture and interstices finely pimctate aiid 

 rugose. Femora with slender, depressed, elongate scales ; the tibiae with 

 outstanding, moderately fine setae. 



Eyes large, nearly flat, rounded outwardly, truncate inwardly, just 

 free from the thoracic margin, as in the preceding species. 



The more scanty vestiture and the sculpture of the thorax render this 

 species distinct. 



Male. — Length (rostrum exclusive), 2| lines ; breadth, 1| line.
