PAPER. 



Studies in Rhynchophora (Coleoptera). 

 V. The Genus Rhyncogonus.

Rhyncogonus Sharp, 1885. 



Tr. Dublin Soc., Ser. 2, Vol. Ill, p. 176. 

 When I established this genus, I indicated its relations to 

 Celeuthetes and EJytnnus. These two genera are placed by 

 Lacordaire in the division Celeuthetides, and it would there- 

 fore appear that I was of opinion that Rhyncogonus is a Cele- 

 uthetid, though I specially pointed out its similarity to Otio- 

 rhynchus, which Lacordaire considers to be a member of ;i 

 group of general (Otiorhynchides vrais) distinct from Peleu- 

 thetides. In order to settle the position of this interesting and 

 important division of the Hawaiian fauna, I have reinvesti 

 gated the question, with the result of finding that Rhyncojonus 

 has characters so peculiar that it should form a separate group 

 of Otiorhynchidae that may be called Rhyncogonides triba nov 

 The chief character of the gToup consists in the form of the 

 buccal cavity ; this is not tilled externally by the mentum, so 

 that the maxillae are visible for all their length, while tho 

 maxillary cleft extends backwards beyond the junction of the
