 Linngeus, 1758, p. 489 ; id., 1767, p. 799 ; Jordan, 1911, p. 235. 

 Hyloicus, Hiibner, 1822. p. 138 (part.) ; Roths. & Jord., 1903, 



p. 116. 

 Thamnoecha, Roths. & Jord., 1903, p. 153. 



Genotype : ligustri Linn. (Jordan, in Seitz, Pal. ii, p. 235). 



The only species of this genus occurring in India, uniformis 

 Butler, was placed by Rothschild and Jordan (1903) in a new 

 genus, Thamnoecha. Seitz (1928) places it in the genus Sphinx 

 Linn., which Rothschild and Jordan (1903) called Hyloicus 

 Hiibner. The name Sphinx Linn, has been adopted instead of 

 Hyloicus Hiibner on the suggestion of the Committee on 

 Nomenclature of the International Zoological Congress. The 

 characters given below apply to the one Indian representative 

 of the genus. 



Imago. — "(J. Antenna long (tip broken off in the three 

 specimens seen), distinctly narrowed at the base, the seg-

 feebly dilated laterad subdorsally, almost as long as high,

 bristles. Palpus small, rough. Tongue short. Tibiae not 

 spiny ; spurs very short, proximal pair of hind tibia absent ; 

 no pul villus, paronychium very small, without lobes, first 

 segment of front tarsus with four long spines, the apical one 

 nearly half the length of the segment, second segment as long 

 as the first.

 Harpe narrow, without patch of modified scales, subdorsal 

 fold of inner surface high, with bristles ; harpe simple, not 

 dentate, ending in an obtuse process. Penis-sheath thin, 

 prolonged into a flat, feebly concave process curving sideways, 

 ending in a verv short pointed hook. 2 unknown " (Roths.

Hab. Nearctic, Neotropic and Palsearctic Regions. One 

 Indian species, of which the early stages are unknown.
