222 COLKOl-'t'EKA. 



3rd interstice, ami iK'ai' tin' side' almost unity's with a less distinct lateral 

 mark. 



Rostrum nearly jdane, about lialt' the length of the thorax, in i'l'ont 

 not as broad us the head, much narrowed behind, feebly trisulcate. 

 Eyes flat, with coarse facets, longitudinally oval, situated in front, on 

 the u})per surface, the interval between tlu'm not more than the width 

 of each. Thorax slightly broadet- than long, widest at the base, wliei-e 

 it is obliquely curved towards the sides, gradually narrowed anteiiorly, 

 its surface moderately coarsely and closely punctured. Scutellum in- 

 visible. Elytra twice the length <d' the thorax, the base arcuate- 

 emarginate, closely adapted to the thorax and nu wider than it is tliere, 

 but nearly twice as broad behind the middle, their sides are moderately 

 rounded, but not at all explanate or margined, and considerably 

 narrowed below and near the apices; each Inis 5 dorsal, moderately 

 coarsely punctured but not deep striae, and slightly elevated simple 

 interstices. 



Legs stout, with a few fine, rather short, decumbent grey setae, the 

 hind pairs of tibiae witli yellow outstanding cilia near the exti-emity, 

 the antei'ior pair widest at the middle, and much nan-owed externally 

 towards the extremity, with small terminal spurs; tarsi normal. 



Scape glabrous, implanted just before the middle and reaching the 

 back of the eye, slightly curved, rather slender, but subclavate at the 

 extremity; basal joint of funiculus considerably thicker but hardly 

 longer than the 2nd, 3rd and iih just a little longer than broad, 5th 

 and 6th bead-like, 7th very slightly larger; club oblong-oval, finely 

 pubescent, its 1st joint subtriangular, the next largest and subquadrate, 

 the '-Ivd narrower. 



The pyriform contour, dark elytial marks, and the form and position 

 of the eyes are its distinctive features. 



Length (rostrum inclusive), 2A nnn. ; breadth, H mm.

 the ground, on the 12th April, 1912, by Mr. T. Hall. 



3614. Geochus suffusus sp. nov. 



Subovate, modei-ately convex and shining; sparingly and irregularly 

 clothed with distinct, but not coarse, suberect straw-coloured setae, whicli 

 are most numerous, yet not concentrated, on the after part of the 

 elytra; thorax almost wholly, elytra partly rufescent, the sides and parts 

 of the disc of these latter more or less fusco-piceous, and usually with a 

 fulvescent or reddish band just below the top of the posterior declivity; 

 rostrum dull piceous, legs fuscous, tarsi and antennae fusco-rufous, the 

 latter sometimes fulvescent. 



Rostrum about half the length of the thorax, of normal shape, with 

 3 indistinct carinae which become convergent behind. Eyes moderately 

 large, coarsely granulate, extending to the sides of the head. Thorax 

 rather broadei- than long, widest at the base, gradually narrowed towards 

 the front, only obsoletely constricted thei-e, coarsely and closely punctate, 

 its base oblique towai'ds the sides. Elytra closely ap])lied to the thorax, 

 of the same width as it is at the base, twice its length, their sides 

 rounded, widest near the middle, the declivity subvertical; they are 

 coarsely punctate-striate near the suture, and the interstices there are 

 slightly elevated, near the sides the striae are less distinct. 



Legs rather long, with slender and rather short decumbent greyish 

 setae; anterior tibiae Ijioad above, not angulate below the middle,
