cornmuu oiu; (S./'/ici/'onJ/ift) by the iiairow border of the wings;, 

 wiiicli is entirely brown, by the black instead of crimson band 

 across the abdomen, and by the under side, which is variegated 

 with black and white. 



The larvne, which have erroneously been stated by some authors 

 to feed upon the wood of Willows, have been bred from the eggs 

 by my friend J. C. Dale, Esq., to whom I am indebted for a 

 drawing and account of the Caterpillars : when about ten days 

 old they have several furcate spines upon each segment of the 

 abdomen, that entirely disappear when they are full fed, at which 

 period they vary exceedingly. 



The perfect insects are remarkably swift upon the wing, and 

 make a humming noise similar to a humble-bee ; they have been 

 taken by Mr. Dale at Enborne, near Newbury, Berkshire, in some 

 abundance, the end of May and beginning of June : they are 

 URich attached to damp places in woods and moist meadows, 

 where they are attracted by various flowers, especially Pedicularis 

 paliidns and syhaiica, about wluch they fly, extracting honey 

 from the nectaries whilst on the wing, like the Humming Bird 

 and other Sphinges. 



Svabiosa succisa (Devirs-bit Scabious), the plant upon which 

 ilie Caterpillars feed, is figured in the plate.
