Differs from the description of peccttarins (trom Batchian) in 

 being smaller, the 1st joint of the funicle longer than the 3rd, and 

 the prothorax without four white spots across the middle and 

 one at apex.

I have to thank Messrs. Etheridge and Rainbow for calling 

 my attention to the fact that this name, although not appearing 

 in Scudder, had been previously used* for a genus of fo.ssils. 

 As a substitute therefore for the genus of weevils, I propose the 

 name Derbyidla.
