I'll SPHINX. 



with rows of squarish black spots, and is often seert 

 feeding on various meadow plants and grasses: it 

 does not undergo its change under ground, but 

 encloses itself in an oval shining yellow web of 

 silk, attached to the stem of some grass, c. In 

 this it changes into a chrysalis, out of which in 

 about the space of three weeks emerges the com- 

 plete insect. 



Others of the smaller Sphinges are remarkable 

 for having the wings in a, considerable degree 

 transparent: of this kind is the Sphinx ap'iformis, 

 which is of an aspect at first sight more resem- 

 bling that of a wasp or hornet than of a Sphinx, 

 the wings being transparent with merely a slight 

 edging of brown, and the thorax and abdomen 

 varied with black and yellow. The caterpillar 

 inhabits the hollows of Poplar, Sallow, Willow, 

 and Lime trees, feeding on the substance of the 

 bark; changing to a chrysalis in April, and the 

 Fly appearing in the month of June. 



Sphinx crabroniformis is so much like the former 

 as scarcely to be distinguished from it, and in- 

 habits the hollows of the Sallow and other Willows, 

 feeding on the wood: it changes to a chrysalis in 

 May, and the Fly appears in July.
