464 REVISION OP THE AUSTRALIAN CURCULIONIDiE, xii., 



Head coarsely punctate; with a distinct median carina; eyes 

 finely faceted. Rostrum slightly inflated between base and an- 

 tennae; coarsely punctate. Prothorax moderately convex; with a 

 distinct median carina; with dense, large, round, and rather shal- 

 low punctures. Elytra elongate-subcordate, with series of large, 

 deep, oblong punctures, becoming smaller and more rounded 

 towards sides and disappearing posteriorly; interstices punctate, 

 behind each puncture subgranulate, third and fifth moderately but 

 distinctly (the seventh less noticeably) raised. Tibiae feebly stri- 

 ated, the front pair rather strongly bisinuate beneath, subapical 

 tooth indistinct. Length, 8|-1 Omm. 



Hab. — New South Wales: Illawarra. 



Each of the punctures on the interstices appears to have been 

 impressed, so that a small posterior portion is raised, these por- 

 tions are sometimes polished, so that the elytra appear subgranu- 

 late. 



Cryptorhynchus fuliginosus Boisd., is placed in Master's Cata- 

 logue as a synonym of Rhynchcenus luridus Fabr., as is also 

 Acalles immansuetus Bohem. Dr. Boisduval's description is insuf- 

 ficient for the identification of C. fuliginosus, but fortunately the 

 type is still extant. M. Lesne recently examined it, and sent some 

 notes and sketches of it that have been reproduced in these Pro- 

 ceedings.* From these, it can be confidently identified as 0. plin- 

 thoides. It is also A. immansuetus, but whether Rhynchcenus 

 luridus or not seems doubtful, f It can scarcely, however, be the 

 A. luridus known to Mr. Pascoe, as he states t that that species 

 belongs to Poropterus.
