Type, A . farinosa, Weber. 



iSince using the name Aphana for this genus (Faun. B. 1. 

 supra), when I thought I had solved the synonymic problem, 

 I have found that Guerin, in first describing this-genus under 

 the name of Aphana (Voy. ' Coquille,^ Zool. ii. (2) i. p. 1S4, 

 1832), gave as the type his A. fuscata from New (Guinea. 

 This genus is therefore structurally distinct from other species 

 included subsequently in Aphcena^ Aphakia, Burm., and 

 Penthicodes thus becomes available. Blaiichard regarded the 

 name Ajjhana as preoccupied by Aphinus, Lap., an argument 

 1 did not and do not follow ; but the type of Guerin's Aphcena 

 settles the question.
