Underside of head and middle of meso- and metasterna 

 more or less smooth, metepisterna exceptionally long and 

 narrow. Fourth joint of tarsi deeply emarginate, almost 

 bilobed — indeed, the species might be put into the genus 

 Creagris quite as appropriately as into Macrochilus. 



Burma: Taung-ngu (G. Q. Corbett), 2 ex. My collection. 



Macrochilus niger, sp. n. 



Length 16-17 mm. ; width 5*5-6 - mm. 



Black, rather dull ; elytra each with a median orange spot, 

 apex of palpi reddish. Body coarsely pubescent, hairs on 

 underside of tarsi dark brown. 



Head (2 - 5 mm. wide) moderately convex, very coarsely 

 punctate (except front, which has only a few punctures), neck 

 smooth, gense sloping gently to neck ; frontal fovese and 

 clypeal suture strongly marked, clypeus slightly emarginate 

 in front, with a row of small closely placed setiferous punc- 

 tures ; labrum with all setae on upper surface, narrowed in 

 front, sides parallel at base, with a short impressed longitu- 

 dinal furrow on each side; labial palpi small, penultimate 

 joint plurisetose, last joint of maxillaries elongate-triangular, 

 slightly flattened, a little shorter than joint 1 of antennae; 

 antennae hardly reaching middle of body, joint 1 longest and 

 thickest, 2 half as long, remainder nearly equal, but 3 a little 

 longer than the others; mandibles short and very sharp, with 

 a rounded tooth at base ; tooth of men turn nearly as long as 

 lobes, with only one setiferous pore on each side at base, both 

 tooth and lobes very long and sharp, epilobes well marked, 

 with upper margin sinuate ; ligula not very wide, apex 

 faintly emarginate, deeply depressed at sides of base beneath, 

 three setse on each side along outer margin of median channel. 



Prothorax slightly convex, transverse, hardly wider than 

 head, half as wide again as long, widest at a fourth from apex, 

 sides rounded in front, sinuate at some little distance from 

 base; front angles rounded, hind angles obtuse and a little 

 reflexed, base slightly but widely produced in middle, the 

 sides distinctly emarginate; median line faint, transverse 

 impressions and basal foveas well marked, surface a little 

 uneven, very coarsely and confluently punctate. 



Elytra elongate, parallel, nearly twice as long as wide, 

 basal area deeply depressed, shoulders square, evenly but 

 brusquely rounded behind, border at base almost dentate over 

 interval 6, where the depressed area commences; punctate- 

 striate, with moderately convex intervals, flatter on disk and 

 towards apex, a row of punctures along each stria, but this
