This species is extremely variable in coloration, but fairly 

 constant in structural characters. The ground-colour is pale 

 vellow or yellow-brown, and the variation consists in the extent 

 to which black is distributed over the various parts of the body. 

 The head may be completely or partly black; when it is yellow- 

 brown there are usually two round black spots on the vertex. The 

 four basal segments ot the antenna are usually yellow-brown aud 

 never wholly black, sometimes the upper surface only is black ; 

 the five apical segments are usually dark and never entirely brown, 

 only the black colour varies in intensity. The prothorax may be 

 light yellow, red-brown, or black ; in the latter case sometimes 

 the edges are faintly yellow. The scutellum is generally black, 

 sometimes red-brown or lighter. The elytra may be entirely 

 yellow, red-brown, or black ; otherwise they have two black 

 transverse bands alternating with yellow ones; the length of 

 these bands varies considerably, and the basal black band very 

 often does not reach the side margins of the elytra ; sometimes 

 three shades of colour, viz. pale yellow, black, and red-brown, are 

 at once present on the elytra; the basal black band is in some 

 examples prolonged triangularly along the suture to meet the
