498 Mr. II. E. Andrewes on Oriental Carabidee. 



18 (17). Ligula rounded in front, penultimate joint of 

 labial palpi bisetose, head and protborax 

 red, elytra piceous, but with a faint bluish 

 tinge. Length 6"5 mm bicolvr, sp. n. 



Macrochilus immanis, sp. n. 



Length 24-26 mm. ; width 7-5-8'5 mm. 

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

 a very faint spot on the median smooth area of vertex, apex 

 of palpi and front trochanters dull red, hind margin of ventral 

 segments (except last one) testaceous. Body coarsely pubes- 

 cent throughout (except where otherwise indicated) but 

 shiny, pubescence at apex of tibiae and on underside of tarsi 

 yellow-red. 



Head (4 - 5 mm. wide) rather flat, very coarsely punctate, 

 neck and a small area on vertex smooth, gense sloping gently 

 lo neck; ligula rather narrow, slightly emarginate at apex, 

 hollowed out above with a median carina ; on under surface 

 with four or five pairs of setse along sides of median ridge 

 and channel ; tooth of mentum bordered, shorter than side- 

 lobes, with five setiferous pores along each side, lobes with a 

 narrow epilobe ; labial palpi small, penultimate bisetose (but 

 with some additional minute hairs), maxillary palpi large, 

 last joint widening gradually to apex, where it is as thick as 

 joint 1 of antennas ; labrum with equidistant setse, all on 

 upper surface, nearly parallel at base, contracted to a rounded 

 point in front, faintly depressed at sides of base; antennse 

 nearly reaching middle of body, joint 1 long and thick, the 

 rest subequal, but 3, 4, and 11 are a little longer than the 

 others. 



Prothorax hardly wider than head and very little wider 

 than long, widest at a fourth from apex, moderately convex, 

 front angles quite rounded, sides with a fine border, rounded 

 in front, sinuate near hind angles, which are sharp, strongly 

 reflexed, and project a little laterally, sides of base oblique 

 and emarginate ; surface coarsely but not very closely punc- 

 tate, median line very faint, but there is a depressed area 

 surrounding it, and the transverse impressions and basal fovece 

 are all strongly marked. 



Klytra elongate, parallel, twice as long as wide, basal area 

 deeply depressed, forming a short peduncle, puuctate-striate, 

 intervals rather flat, a row of punctures along the sides of each 

 stria, but these are not quite evenly disposed and become 

 more irregular towaids apex, interval 8 twice as wide as the 

 others; orange-coloured spots placed just before middle, 

 nearly square, covering intervals 2—7.
