Ccelostomus ruber, sp. n. 



Length 5-0-5-5 mm. ; widtlj 2-0-.2-2 mm. 



Dark red, elytra and metastcrnura a little lighter, joints 

 4-10 of autennfc and middle of venter darker, palpi 

 testaceous. Surface moderately shiny and appearing rather 

 greasy. 



Head rather small, moderately convex behind, flat in front, 

 sides strongly bordered, a distinct rounded angle at each 

 front corner, frontal furrows rather short and deep, divergent 

 behind, and uneven at bottom, eyes small and rather flat, 

 antennffi incrassate towards the apex but hardly moniliforra, 

 reaching a little beyond base of prothorax, pubescent from 

 middle of joint 4. Prothora.r qxia-dnite and rather flat, a good 

 deal wider than head, a third as wide again as long, rather 

 wider at base than apex, base trnncate, apex slightly 

 eraarginate, sides very lightly rounded in front, and equally 

 lightly sinuate before base, only sliglitly contracted behind, 

 border very fine, a pore at hind angle, but no marginal setae 

 are visible on any of the specimens, hind angles projecting 

 a little laterally and slightly acute; median line deep, 

 reaching base but not apex, base depressed between fovea?, 

 which are Avide and deep, converging a little and pointed in 

 front, reaching base behind, which — regarded vertically — is 

 strongly bisinuate; surface nearly smooth, a few punctures 

 near hind angles, and iisually traces of puneturation or 

 crenulation in the def)ressions and marginal channel. Elytra 

 convex, short-ovate, rather pointed behind, where the margin 

 is distinctly sinuate, three-quarters as wide again as prothorax, 

 less than half as long again as wide, sides strongly contracted 

 at base, an obtuse tooth projecting forwards at shoulder, 

 basal border distinct ; striae shallow, deeper at apex, finely 

 and closely punctate, stria 1 continued nearly to basal border, 

 a large pore at base of 3, 1-2 and 7 deep to apex, 3—6 not 

 reaching apex, intervals flat on disk, convex near apex, 

 8 wider near apex, with a series of very large umbilieate pores, 

 Avidely interrupted at middle, surface smooth. Underside 

 smooth along median line, coarseh' punctate at sides, pro- 

 and raetasternum channelled, prosternal process with a 

 large pore at apex, metasternum bordered between themeso- 

 coxae, metepisterna elongate, ventral segments crenulate at 

 base, as in some species of Cruspedophorus. Legs rather 

 short, ])rotibice with one or two minute spines near apex of
