the Tl ow stripes of the thorax are lost posteriorly m the genera,

the neck All the margins of the pronotum are commonly white | 
The side of the prothorai is yellow, with two very broad, longitudd

margin behind. The side-pieces of the meso- and meta-thorax ar 
Zskv with yellow edges, and the coxae are dusky externally; rl 
pale specimens both these and the side-pieces are concolorous.

black with a Y-shaped mark, the short stem of which reaches tbl

black patch between them, and leave a narrow black stripe outsid 
The extreme margin of the scutellum is yellow. Sometimes tl;

The wing covers are sparingly’ pubescent with yellow hair, ar 
coarsely and closely punctured, the punctures being more or 1 
confluent so as to give the surface a rugose appearance. Th

The abdomen is pubescent, and minutely punctured. It varies | 
color from black, or reddish black, with two broad yellowish strjl
