SPHINGINTE. 41 



covered with scattered black dots, except on the wing-cases. 

 The spiracles are visible as large black spots. 



The moth is very abundant throughout Africa and Southern 

 Asia, but becomes scarcer and more local in Southern Europe, 

 and migrates northward in Central Europe in warm summers. 

 Single specimens have been captured in the South of England 

 at long intervals. 



SUC-FAMILY III. AMBULICIN^. 



The Amhulicimji are an exclusively tropical sub-family, and 

 barely touch the Pal^earctic Region, their northern limits being 

 North India, North China, and Japan. The typical species 

 are large moths, with long and rather narrow wings. The 

 fore-wings are often pointed at the tips, the palpi are rounded 

 externally, the antenna are slender, the eyes prominent, the 

 thorax short, and the abdomen of the male rather long, with 

 a lateral angular expansion before the tip. In the larva the 

 anterior segments are not retractile, but taper slightly towards 

 the rather large head ; the horn is long and oblique, and 

 there is a row of oblique stripes on the sides. 



SUBFAMILY IV. SPHINGIN/E. 



The Sj>hinguhc are moths v.ith moderately long and broad 

 fore-wings, not very pointed at the tips, and generally grey or 

 brown. The hind-wings are varied with red, yellow, or grey, 

 and the sides of the abdomen are marked with spots of the 

 same colours. The head is generally rather small, but the 

 proboscis is usually very long. In the larva, the anterior 

 segments are not retractile, and hardly narrowed ; the horn is 

 usually long, and the sides of the body are oblic^uely striped.
