234 Mr. C. O. Waterhouse on netc Coleoptera 



The antenna are pale, but dusky at the apex. There 

 are no distinct markings on the thorax. The elytra have 

 a purple gloss ; on each there are the following golden 

 markings: an elongate spot on the suture at the scutellum, a 

 triangular spot in the middle of the base (extending a little 

 over the shoulder), a narrow fascia just before the middle, 

 commencing on the margin, is directed obliquely backwards 

 for a short distance, and then tvu-ns obliquely at a right 

 angle forwards to a level with the starting point, and then 

 turns again backwards at an acute angle and joins the 

 suture ; there are also two lunate spots at some distance 

 from the apex, Avhich, with the corresponding pair on the 

 other elytron, form an interrupted fascia. 



Hab. — S. Australia (Bakewell). 



This species much resembles M. elegans, but is much 

 smaller and narrower, and has two spots at the apex of 

 each elytron, instead of one, &c. 



There is a specimen in the Museum which closely 

 resembles this species, but has the spot in the middle 

 of the base of the elytra more elongate; the spot below 

 the scutellum divides posteriorly, and the mesial .band 

 appears more strongly zig-zag; the thorax also is obscurely 

 marked with fliscous, and the anterior legs are less pale. 

 This may be a mere variety. It measures H lines. 



There are also two examples which resemble the above, 

 but which are black, with the suture of the elytra only 

 golden-pubescent ; the base of the antennfe, the palpi and 

 the anterior legs are pitchy. Long. 2^ lin. 



These are probably a distinct species, but the examples 

 being: in bad condition I do not venture to describe them.

Nigra; capite thoraceque flavo-rufis; elytris basi an- 

 gustissime, macula parva juxta basin, sutura usque ad

Head and thorax pale red, with yellow silky pubescence. 

 Antennae rather long, the 4th to 10th joints distinctly 

 longer than broad. Scutellum silvery. Elytra black, 

 with the following silvery-white markings; the base
