724 REVISION OF THE AUSTRALIAN CURCULIONIDiE, IX., 



Achoperinus, n.g. 



Eyes moderately large. Scape thin, almost the length of funicle. 

 Pectoral canal terminated between four front coxae. Femora 

 dentate. All else as in Achopera. 



This genus is erected to receive Cryptorhynchus infulatus Er., 

 a species supposed by Mr. Pascoe to belong to Ephrycus; that 

 genus, however, has the mesosternal receptacle decidedly open 

 and the eyes finely faceted. 



Achoperinus infulatus Er.; Mast. Cat. Sp. No.5545. 

 Cryptorhynchus infulatus Er. 



Elliptic-ovate, gently convex. Rostrum piceous, antennae and 

 tarsi red; derm elsewhere concealed. Densely clothed with soft, 

 loose, dark brown scales feebly variegated at apex and sides of 

 prothorax; a patch of ochreous scales on median line at base, a 

 patch of similar scales at the side beyond middle of each elytron; 

 each of these with a very distinct spot of white scales on disc 

 just before middle; head and base of rostrum with dingy scales, 

 but a white trilobed patch on vertex. Under surface and legs 

 with brown and dingy white scales ; pectoral canal densely 

 clothed. Prothorax with six fascicles: two at apex and four 

 across middle; elytra with obscure fascicles, except for a very 

 distinct one of black scales on each side at summit of posterior 

 declivity close to suture. 



Eyes almost round, separation slightly less than width of 

 rostrum at base. Rostrum not very long, moderately curved, 

 very feebly increasing in width to apex; rather finely punctate. 

 Scape inserted two-fifths from apex, slightly curved; 1st joint of 

 funicle noticeably longer than 2nd; club almost the length of six 

 preceding joints. Prothorax feebly transverse, apex narrowed, 

 base bisinuate, punctures entirely concealed. Scutellum small. 

 Elytra about once and one-third the width of prothorax, base 

 trisinuate, shoulders rounded; striate-punctate, stria? almost, the 

 punctures entirely concealed. Punctures of under surface entirely 

 concealed; 3rd and 4th abdominal segments combined the length
