The peculiar lateral asymmetry exhibited in the Hemarid 

 genitalia will be dealt with in our consideration of the Hemariiiac. 

 The other imaginal specialisations will also be considered when we 

 deal with the various subfamilies. 



Subfam : Hemarin^e. 



The clearwinged Sphingids, of which Hcmaris fuciformis is 



figured by Reaumur (Mb//., ii., pi. xii., figs. 9 — 10), had already 



received the name " d'ailes vitrees " when Reaumur changed (loc. 



cit., p. 277) it to " Papillons mouches." Owing to their superficial 



* 1 cannot discriminate the North American species, C. chamoenerii, from 

 European C. gallii, and I see by Butler that Strecker (Can. Put., iv., p. 206) 

 considers them identical (Griffiths). 



f Though the frenulum agrees fairly well with that of S. ligustri, I cannot help 

 thinking that British entomologists ought to separate this species genetically From 

 S. ligustri. In development of haustellum, shape of pupa and general characters it 

 agrees much more closely with Protoparce celeus, ringr/lata, Carolina and other 

 species with which genus Butler places it. The Australian specimens of A. con- 

 volvuli seem to differ from European and African forms in my cabinet (Griffiths).
