702 THE INSECTS OF THE MACLAY-COAST, NEW GUINEA, 



Scutellum triangular, rounded behind, sparsely punctured. Elytra 

 of the width of the thorax at the base, and nearly four times the 

 length, widening a little towards the apex, the puncturation 

 irregular and denser than on the thorax, and the scales rather 

 longer. Each elytron has five longitudinal lines or costa? ; the 

 first close to the suture distinctly marked, the others at equal 

 distances apart and scarcely costate, excepting the fifth, which is 

 distinctly raised. The pygidium is triangular with rounded 

 angles, and is densely variolose-punctate. The legs and entire 

 under surface are of a nit-id pitchy brown ; the pro-meso and 

 metasternum clothed in the middle with yellow pile. Fore tibia? 

 with three strong teeth towards the apex externally ; the middle 

 and hind tibia? with three short nearly equidistant teeth on the 

 outer margin. Long. 16 lin. 

 One specimen. Maclay Coast.

 Thorax transverse, a little emarginate in front and sinuate behind, 

 the antei'ior angles rather rounded, and the sides rounded in 

 the middle and narrowed slightly towards the posterior angles. 

 Scutellum rounded behind, its width at the base more than thrice 

 its vertical length. Elytra about the width of the thorax and 

 about three times the length, the callus on the hinder part very 

 conspicuous. 



Under surface dark piceous, the abdominal segments densely 

 clothed with scales, and the mouth pro- and mesosternum with red 

 hair. Fore tibiae strongly tridentate, the other tibia? slight, and 

 minutely armed ; the posterior thighs narrow at the base, swelling
