and angular, with two basal and two lateral dark spots ; 

 abdomen large, ovate, more than twice the width of the 

 head, the first segment semicircular and chestnut, the second

For specimens of this elegant species I am indebted to 

 Mr. Thompson, who took them from the Cygnus Bewickii

 through the kindness of T. C. Heysham, Esq. The lateral 

 fasciae are variable both as to diameter and extent, as well 

 as intensity of colour.
