colour markings and size. A fully marked example is of pale 

 testaceous-brown colour, with the antennje (except at the base) 

 and the back of the head blackish, the scutellum dark brown and 

 a number of blackish markings on the elytra consisting of patches 

 on the interstices so arranged as to form a kind of festoon extend- 

 ing from one humeral callus to another and crossing the suture 

 about its middle, and another coalescing with it on the suture, 

 and having its extremities not far from the lateral margin and 

 the apex on each elj^trou ; each humeral callus and the subapical 

 extremity of the hinder festoon being also connected by a black- 

 ish vitta which runs along the inner edge of the marginal part of 

 the elytra. There are also some wdiitish Knes on the elytra which 

 are probably silvery in living specimens. Nearly all the markings 

 on the elytra are liable to be wanting, but there are very few 

 examples (except the var. ? mentioned below) in which the 

 blotches forming the curve on the hinder part of the elytra are 

 not traceable. The convexity of that curve being directed 

 forivard is a good superficial distinction of this species from 

 several which somewhat resemble it. In some examples there is 

 a dark submarginal blotch on either side of the prothorax. The 

 size is long. 2-2| lines. 



Var. 1 erubeacens. Tota testacea (elytris nonnihil rufescentibus 

 et antennis apicem versus picescentibus exceptis). This insect is 

 lar'^'er than the type — ver}^ few examples being less than 2h lines 

 lono-, whereas few- of the type attain that size — and the ntales are 

 certainly somewhat wider than the males with dark markings on 

 the elytra ; some specimens have white lines on the elytra, which 

 are straighter and more continuous than those on the elytra of 

 the other form ; nevertheless I think it is only a variety.

I have not seen an authentic type of this species, but never- 

 theless have little or no doubt of the correctness of my identifica- 

 tion, as the insect is one with well-marked superficial characters. 

 It and the next species are closely allied and are readily dis- 

 tino'uished from their immediate allies by the feebleness of the
