568 COLEOPTERA. 



irregularly distributed, covering the sides of the thorax and forming a 

 streak along the middle ; on the elytra the hairs arc concentrated across 

 and below the shoulders, behind the scutellum a patch is divided by the 

 suture, there a similarly divided one in line with the hind thighs and a 

 larger oblique one a little in advance extends forwards towards the side, 

 there is another, also divided by the suture, farther back and a larger patch 

 at each side of it, the apical portion is covered ; on the head the hairs are 

 more slender and scattered ; legs fusco-rufous, tarsi darker. 



Rostrum a third longer than thorax, gently expanded towards the 

 bidentate apex, obtusely angulate at the antennal insertion, near the base : 

 rather finely punctate, less distinctly in front. Head nearly as broad 

 as thorax, very coarsely and closely punctured, with raised interstices. Eyes 

 large and prominent. Thorax rather broader than long, gradually narrowed 

 towards the truncate apex, base strongly bisinuate ; disc coarsely, very 

 irregularly transversely rugose, punctate. Scutellum transverse, punctate 

 and finely pubescent. Elytra six times the length of thorax, of the same 

 width at the base, strongly bicurvate there, the suboblique shoulders a 

 third broader, curvedly narrowed near the obtuse apices ; their sculpture 

 consists of elevated, somewhat irregular transverse rugae and punctate 

 intervals. 



Antennae somewhat infuscate, second joint shorter than the basal and 

 hardly as thick, joints 3-7 elongate, gradually decreasing in length, eighth 

 elongate-triangular, ninth and tenth oblong, eleventh rather shorter but 

 with a conical terminal appendage. 



Femora covered with slender fulvescent setae, tibiae and tarsi with 

 shorter nigrescent ones. 



Underside with fulvescent vestiture, very dense along the sides of the 

 breag;t, the abdomen with bare shining spots ; metasternum cupreo-violaceous, 

 grooved along the middle. 



The sculpture is coarser than that of P. aenescens (3770), the surface 

 is more brightly coloured, the vestiture is quite differently arranged, joints 

 5-8 of the antennae are shorter, the tibiae are not serrate inwardly, the 

 thorax is less transversal, the rostrum is longer, but its basal punctation is 

 not close. 



Length (rostrum inclusive), 10 mm. ; breadth, 2|- mm.

 4114. Geochus pictulus sp. nov. 



Subovate, broad, narrowed anteriorly, widest behind the shoulders, 

 moderately convex and nitid ; sparingly clothed with decumbent and 

 suberect, yellowish-grey, slender scales ; flavo-castaneous, the thorax with 

 a dark fuscous spot at each side near the base ; each elytron similarly dark, 

 but interruptedly, from the hind thigh towards the apex but not extending 

 to the suture, sometimes prolonged as a streak to the middle of the base ; 

 rostrum dark near the base, rufescent in front ; antennae fulvescent, cluli 

 slightly infuscate. 



Rostrum quite half the length of thorax, stout, broader near the apex 

 than behind, indistinctly sculptured, with four series of small scales
