REV^ISION OF THE AUSTRALIAN CURCULIONTD^ 



BELONGING TO THE SUBFAMILY 



CR YPTOlillYNCHIDES. 



Part X. 



By Arthur M. Lea. 



Parts ix. and x. deal with Chcetectetorus and its allies, all of 

 which belong to the " Cry ptorhynchides vrais " of Lacordaire. 

 Of the species recorded from Australia, I am acquainted with all 

 except Chcetectetoriis hcedtdus Pasc, and Gasterocercus nigromveus 

 Chevr. The latter species probably does not belong to Gastero- 

 cercus, as M. Chevrolat proposed for it the generic name of 

 Coptoscelis, without, however, giving a generic description. 



A character made use of by Mr. Pascoe in his table, viz., 

 " Rostrum curved" as against " Rostrum straight" is not to be 

 relied on, as both Menios and Metyrus include species having the 

 rostrum straight, and others having it more or less distinctly 

 curved; in fact this character seldom appears to be of primary 

 importance in the subfamily. 



Exithius was regarded by Mr. Pascoe as being allied to Chct- 

 iectetorus, probably on account of the clothing and shape of the 

 prothorax; but the short metasteinum (though longer than in 

 IHhiacia'^''), very narrow metasternal episterna, excavated head, 

 and partial soldering of the two basal segments of abdomen in 

 middle, would seem to exclude it from all association with that 

 genus and denote an approach to Paleticus. 



In nearly all the genera the metasternum is elongate, and w itli 

 large or comparatively large episterna. The mesosternal rece[>- 

 tacle is subject to great variation, being decidedly open in some, 



* It is with considerable doubt that I refer Titnaria to the {^roup.
