PRTLAMPELIX^E. 259 



Subfamily PHILAMPEL1TOE. 



Roths. & Jord., 1903, p. 475. 



'■ ^2. Sexual armature symmetrical; tenth segment (^) 

 not divided mesially, the tergite narrow ; seventh sternite 

 (2) membranaceous distally, never spinose. Abdominal 

 spines uniserial only in Pholus and Tinostoma [both American]. 

 Xo high crest on mesonotum, and second segment of palpus 

 (skeleton) not angulate laterally in anv species" (Roths. & 

 Jord., I.e. 1903). 



Cosmopolitan. Two tribes, only one of which, Nephelini, 

 is represented in India, the other, Philampelini, being American. 



Tribe NEPHELINI. 

 Nephelic^:, Roths. & Jord. 1903, p. 498. 



Imago. — " <$Q. Abdominal spines in more than one row. 



" The genera of this tribe are in more than one organ either 

 similar to the Sesiisle or to the CHCEROCAMPiNiE. Very often 

 a genus inclines towards one subfamily in one stage and 

 towards the other subfamily in another stage. Macroglossum, 

 for instance, is Sesiid in the imago and larva but Choerocampid 

 in the pupa ; Ampelophaga is Choerocampid in the imago and 

 larva and Sesiid in the chrysalis. The imago of Atemnora 

 is Sesiid 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 

 Sesiin^e on the one side and in the Chceeocampin^e on the 

 other reappear in the Nephelini, a tribe of PmLAMPELiNiE, 

 which subfamily stands between the two others. 



" Progressive and retrogressive development is about 

 equally frequent in this tribe. The normally non- crested 

 head acquires a crest in reduced forms, like Darapsa, Deidamia 

 and Sphingonsepiopsis, and the eyes become lashed and small. 

 On the other hand, the eyes and the palpi are enlarged in 

 Elibia, Eurypteryx and Giganteop>alpus . The originally conical 

 abdomen is flattened in a number of genera ; the spines, 

 which are never absent, develop like those in the Sesiinje, 

 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 Sesia 

 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 Sesiinje. In the species with strongly spinose 

 and flattened abdomen the first segment is usually closely 

 appressed to the thorax ; in Macroglossum the first tergite
