The genera of this tribe are in more than one organ either similar to the 

 Sesiinae or to the Clioerocampinae. Very often a genus inclines towards one sub- 

 family in one stage and towards the other subfamily in another stage. Macroglossum, 

 for instance, is Sesiad in the imago and larva, but Choerocampid in the pupa ; 

 Amjiclo/ihaga is Ohoerocampid in the imago and larva, and Sesiad in the chrysalis. 

 The imago of Ati'miiora is Sesiad in the strong flat spines, Choerocampid in the large 

 friction-scales. Such similarities are in so far affinities as they show that the lines 

 of development which prevail in the Sesiinae on the one side and in the 

 Choerocampiime on the other reappear in the Nephelicae, a tribe o^ PInlampelinafi, 

 which subfamily stands between the two others. 



Progressive and retrogressive development is about eipially frequent in this tribe. 

 The normally non-crested head acquires a crest in reduced forms, like Darapm, 

 ]>ei(himiu, Spliingonaepiopsis, and the eyes become lashed and small. On the other 

 hand the eyes and the palpi are enlarged in Elihia, EnrijjHeri/x, Giyanteopalpus. 

 The originally conical abdomen is flattened in a number of genera : tlie spines, 

 which are never absent, develop in a similar way as in the Sesiinae, becoming very 

 weak in some genera and very strong and flat in others, Macroglossum and the two 

 genera derived from it agreeing in the spination almost exactly with Scxia and 

 allies ; the basal sternite is not spiuose, or has weak spines, or is as strongly s])inose 

 as the other sternites, and these sometimes nearly as strongly as the tergites, as is 

 also the case in several Sesiinae. In the species with strongly spinose and flattened
