56 COl-EOPTERA. 



luudcriitcly broad mo.sial depression, its iiuiittatioii ajjpareiitiy clo^e but 

 not coarse. Scutelluin oviform, greyish-yellow. Ebjira nearly twice the 

 lenjjth hut not twice the breadth of the thorax, the shoulders, however, are 

 obli(|uely narrowed, so that at the base they are no wider than the thorax ; 

 their sides, at the shoulder.s particularly, are definitely thoujrh obtusely 

 and only moderately elevated from the base to the hind thij^hs, they are 

 narrowed towards the extremity but i\(jt produced or divergent there ; the 

 ,'ird interstices are somewhat elevated at tlie base but n(jt along the middle, 

 and on to]t of the declivity on each there is a conspicuous nodiform <'leva- 

 tion, there is a snuiUer one below ; the 5th are somewhat interruptedly 

 elevated behind, but not at all at the base, and the terminal elevation on 

 each is longer but not as high as that on the 3rd ; at the suture, on a lower 

 plane than the top of the declivity, there is a pair of elongate contiguous 

 protuberances, which, when examined from al)ove, appear to extend further 

 than the apices : the serial ])un(tures are rather elongate, but not close to 

 one another. 



The broad rostrum, submargnuited sides of the elytra, and the con- 

 tiguous posterior projections are good differentiating characters. The 

 scrobes are as elongate as those of the typical species, P. binodes, but extend 

 lower down. The antennae are sto\iter, the scape reaches the back of the 

 eye ; the basal 2 joints of the funiculus are equal in length ; all the joints, 

 however, are shorter and thicker. The thorax is without tubercular sculp- 

 ture. The eyes are oblique, shorter longitudinally, and rather more promi- 

 nent. The hind pairs of tibiae are not denticulated, as in P. caudata. The 

 posterior corbels have double ciliae and a narrow external truncature. 



Length (rostrum inch), 5 lines ; breadth, nearly 2 Hnes. 



Mount Quoin. A single specimen, off an Astelia ; elevation about 

 3,900 ft. Forwarded bv Mr. O'Connor. 



3120. Platyomida tibialis sp. nov. 



Piceo-niger, antennae ferruginous, legs rather darker ; moderately shining, 

 the squamae de]:)ressed, small and rounded, for the most part of a greenish- 

 grey ; the setae scanty and of a tawnv hue, but greyish on the legs, which. 

 however, also bear many small tawny scales. 



Rostrum rather shorter than thorax, the median carina distinct, its 

 punctation longitudinally rugose. Thorax about a fourth longer than broad, 

 subcylindrical, 1 roadly sulcate medially, punctate, but only moderately 

 rugose-granulate. ScmteUum elongate. Elytra oblong, not at all dilated 

 near the liind thighs, gradually narrowed posteriorly, with dentiform apices ; 

 disc moderately plane, the liind slope not abrupt ; their series of pimctures 

 very distinct and regular, the 3rd interstices slightly elevated but not at the 

 base, strongly nodose behind, the 5th moderately. 



Undi'rsidc nigrescent, sliining. sparinglv and finely squamose, irregularly 

 and rather finely punctate. 5th ventral segment nearly smooth and rather 

 convex in the nuddle. 



Differs from P. binodcn in benig narrower, rather Hatter, and with a 

 longer posterior slope. The thorax and scutellum are longer, the elytra 

 much more distinctly punctate. The tibiae are more tfexuous, the posterior 

 curved inwardly and more strongly produced at the inner extremity. Ir 

 differs also in general appearance and vestiture. 



Length (rostrum incl.). 5 lines ; breadth. 1^ lines.
