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

 Se.vinae or to the Choerocumijinac. Very often a genus inclines towards one sub- 

 family in one stage and towards the other subfamily in another stage. Maci'oglossum, 

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

 Ampclophaga is Choerocampid in the imago and larva, and Sesiad in the chrysalis. 

 IHie imago of Atnmnora 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 ou the one side and in the 

 Clioeroeamjiinae on the other reappear in the Nephelicae, a tribe o^ F/iilinnpeliiiai', 

 which subfamily stands between the two others. 



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

 The normally non-crested head actjuires a crest in reduced forms, like Darapsa, 

 De'idamiu, Sp/iingonaepiopsis, and the eyes become lashed and small. On the other 

 hand the eyes and the ])alpi are enlarged in Elibia, Eurijpteri/x, Giganteopalpus. 

 The originally conical abdomen is flattened in a number of genera ; the 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, Macroglossiim and the two 

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

 allies ; the basal sternite is not spinose, or has weak spines, or is as strongly spinose 

 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 sjiinose and flattened
