Mr. H. E. Andrew©.? on Oriental Carabidse. 503 



dilated, triangular; in the maxillaries the antepenultimate = 

 apical, which is triangularly dilated, as in the labials, pen- 

 ultimate about half as long. Antenna? with joint 1 large, 

 cylindrical = 11, 2 about half that length, the remainder 

 increasing gradually in length to apex. Labium rounded in 

 front, hardly pointed, the four inner seta? very small, placed 

 close together at apex, the middle pair being just on the 

 under surface. 



Macrochilus impictus, Wied. 



Length 15'0 mm. ; width 4 - 5 mm. 



Ficeous ; mouth-parts (including labrum), joint 1 of an- 

 tennae, legs, and ventral surface testaceous, margin of pro- 

 thorax brown. Head with front depressed, genas large and 

 sloping. Prothorax rather flat, sides strongly rounded in 

 front, hind angles projecting sideways and reflexed, but not 

 very sharp, produced part of base wide, sides emarginate. 

 Elytra immaculate, depressed just before middle, punctures 

 on intervals quite irregularly disposed. Proepisterna smooth, 

 nearly impunctate. Ligula wide, rectangular, with two pairs 

 of seta? beneath near front margin, which is straight, and 

 another pair further back on sides of channel. Maxillge 

 dilated in middle and sharply contracted to apex. Palpi 

 rather obliquely truncate at apex; labials with penultimate 

 joint plurisetose, rather longer than apical, which is short, 

 setose, and triangularly dilated; maxillaries setose, ante- 

 penultimate longest, apical only a little longer than pen- 

 ultimate, and dilated, as in labials. Men turn with narrow 

 elongate lobes and tooth, latter but little shorter than lobes, 

 and bearing a number of long irregularly disposed setse, 

 epilobes very narrow. Labrum with sides parallel at base, 

 then rounded and Insinuate on each side of apex. Antennae 

 with joint 1 longest, 3 = 4 and only a little shorter than 1, 

 2 nearly as long as 5. 



Macrochilus bicolor, sp. n. 



Length 6*5 mm. ; width 2*5 mm. 



Testaceous; elytra piceous, with a faint bluish tinge, sides 

 and last three segments of ventral surface brown, apex both 

 of mandibles and labrum black. Pubescence grey and rather 

 long. 



Head (]'25 mm. wide) convex, moderately and not very 

 closely punctate, genss elongate, joining neck obliquely ; 

 ligula comparatively short, slightly rounded at apex ; tooth
