of the prothorax is black, with the exception of two broad fulvous 

 irregular vittse extending from the anterior to the posterior margin : 

 prostemum black, shining, projecting between the anterior coxae, and 

 the projection deeply emarginate : scutellum rather long, blunt at the 

 apex, perfectly black : elytra fulvous, shghtly divaricating, conspi- 

 cuously carinated, truncate at the apex, and the truncature sinuate 

 carinated ; the carinse five discoidal, one costal and one sutural ; the 

 first discoidal originates at the base, and nearly runs into the sutural 

 at about one-third of its length ; the second unites with the first at 

 the base and runs into the apical area of the wing ; the third origi- 

 nates at the base and runs into the apical area ; the fourth originates 

 in the humeral angle, dividing at one-third of its length, and the 

 two branches counting as two caruise, there uniting with the two pre- 

 viously described in a confused manner in the apical area : the wings 

 are fuliginous, slightly longer than the elytra, and scarcely folded at 

 the tip : the abdomen and legs are black, the latter of moderate size 

 and proportion : the metatibise are armed vdth two spurs. 



Fem. — Head black, wdth the exception of a fulvescent tinge on the 

 short velvety down of the epicraninm : eyes reniform, or almost ar- 

 cuate, ferrugmous (probably by accident) : antennae rather more than 

 half as long as the body and moderately stout, 11 -jointed; the first 

 joint moderately long ; the second very short ; the third about equal 

 in length to the first, and together with the fourth, fifth, sLxth, seventh 

 and eighth inclusive, deeply notched at the apex, and receiving the 

 base of the next preceding joint in the notch : prothorax uneven on 

 the back, somewhat curved anteriorly, and the anterior half of each 

 lateral margin uniting therewith in producing a somewhat semicir- 

 cular outline ; the posterior half of each lateral margin is concave, 

 and a strong but obtuse central tooth is produced on each side at the 

 point of union of the convex and concave portions of the margin ; 

 the posterior margin is nearly straight ; the colour is velvety black, 

 with two broad fulvous vittae, extending from the anterior to the 

 posterior margin : prostemum black, tliickly sprinkled with a grey 

 pilosity, projecting somewhat between the procoxae, and the pro- 

 jection emarginate : scutellum rather long, rounded at the apex, vel- 

 vety black with fulvous margins : elytra bright fulvous, conspicuously 

 carinated, slightly divaricating, truncate at the apex, and the trunca- 

 tures sinuate : the carinae on each elytron are five in number, and are 

 thus disposed ; the first is near the suture and parallel therewith for 

 rather more than a third of its length ; it unites with the second at 

 the base, and this runs into the apical area and there joins the third ; 

 the third originates at the base, exceeds the second slightly in length, 

 and joins the fourth in the apical area ; the fourth originates near the 

 humeral angle and divides at about a third of its length ; both branches 

 proceed to the apical area, and there unite with the second and third : 

 wings fuliginous, exceeding the elytra in length, and scarcely folded 

 at the tip : legs black. 



Hab. Austraha. I have seen but a single specimen of the male, 

 which is in the Cabinet of the Zoological Society, and one of the fe- 

 male, in the Cabinet of the British MuSeum.
