24 LLOYD S NATURAL HISTORY. 



This large Hawk-moth is a native of India, China, and 

 the Malay peninsula and islands. It expands about five 

 inches. 



The head and thorax are olive- green, the latter with an 

 ashy-grey streak on the sides. The abdomen is olive-green 

 above, and golden yellow on the sides. The fore-wings arc 

 olive-brown, with the basal area olive-green, and the tip pale. 

 There are several parallel dark lines running obliquely from 

 the inner margin towards the tip ; the innermost being 

 angulated upwards to the costa, and beyond these is a fine 

 waved sub-marginal line. In the discoidal cell is a black 

 lunule, and near the hinder angle a black streak. The hind- 

 wings are dark brown, with a broad ochreous band running 

 from the anal angle, parallel to the hind margin. 



The larva, which feeds on yam, is bluish green, with a black 

 and green ocellated spot on the fourth segment, a sub-dorsal 

 line, and a yellow horn. 



GENUS MIAVIA. 



Body moderately long and broad ; abdomen with more or 

 less metallic scaling. Fore-wings with the costa nearly 

 straight, the tip pointed, and the hind margin oblique, with a 

 projection in the middle. Hind-wings slightly sinuated. 



This genus only includes two or three species found in 

 Australia and Amboina. In appearance the moths resemble 

 Isoph's (Hiibner), being rather small Sphinges, with brown 

 fore-wings and red hind-wings ; but Isoples has a longer and 

 narrower abdomen, and the fore-wings are sub-triangular, 

 narrow at the base, and widening towards the extremity, and 

 distinctly marked with oblique lines ; and there is no distinct 

 projection on the hind margin. Several closely-allied species 

 are found in Asia and Africa. The type cf Isoples is 

 /. ihyclia (Linn.).
