MARKINGS OF THE GKAPHIPTERI. 45 



larger on the thorax, and a still larger on the middle of the 

 elytra, all three joining each other. These marks are sur- 

 rounded by a narrow band of pale, golden yellow, then by a 

 broad band of buff, and lastly by a second narrow band of 

 yellow. 



Then there is Graphiptcrus Wcstwoodii, yellow, with a large 

 butterfly-shaped black patch on the elytra ; Grapliipterus cordi- 

 gera, having a similar patch, but looking like a heart suspended 

 by a string. Grapliipterus Scncgalensis is striped with narrow 

 bands of yellow and buff- brown; and Graphiptcrus exclamationis 

 is black, with a grey mark on each elytra, shaped just like a note 

 of exclamation. 



The generic name Graphipterus, or " written-wing," is given 

 to the insects in consequence of the manner in which their 

 elytra are decorated with marks defined as clearly as if they 

 were drawn or written with a pen.
