502 Mr. II. E. Andrewes on Oriental Carabida?. 



I may add one or two further characters, though I have 

 unfortunately seen only one example (in the British Museum), 

 and consequently have not been able to dissect the buccal 

 organs. Ligula with two seta? beneath, not far from apex ; 

 palpi much stouter than in trimaeulaius, Oliv., but not dilated 

 at apex, penultimate of labials plurisetose ; labrum more 

 pointed and curving downwards at apex, the two apical seta? 

 (quite abraded in the specimen before me) evidently small, 

 and placed close together almost on the under surface ; joints 

 2-6 of antennae approximately equal (rest wanting), but 3 

 is slightly longer than the others ; tooth of mentutn with a 

 number of irregularly disposed setiferous pores. 



Macrockilus trimaculatus, Oliv. 



Length 15'0 mm. 



This, the commonest Eastern species in the genus, has 

 been described several times. The ligula is wide, thick, 

 slightly emarginate at apex, hardly channelled beneath, with 

 one or two minute seta? only on under surface. Mentum with 

 tooth sharper and a little shorter than lobes, the tooth with 

 some irregularly disposed seta? behind and two or three along 

 margins near base, epilobes narrow. Maxilla? densely ciliate 

 within. Palpi truncate at apex ; labials with apical joint 

 slightly dilated and a little longer than penultimate, which is 

 bisetose ; maxillaries with 1 = 3, 2 about half that length, 

 apical joint a little dilated. Labrum rounded, a seta on each 

 side at about middle, a smaller pair on front margin, and a 

 minute pair just beneath margin at apex. 



Macrockilus chaudoiri, Andr. 



Length lO'O mm. 



In this species the surface is less closely punctate than in 

 its allies, and the form narrower, middle of front smooth, 

 gena? reaching neck rather abruptly, prothorax with sides of 

 base oblique but almost straight, the median part of the body 

 beneath almost smooth. 



Ligula widened and thickened in front, emarginate, 

 glabrous except for a pair of seta? at each side of apex 

 beneath. Mentum with tooth a little shorter than lobes, 

 tooth glabrous, but a seta on each side at base, epilobes very 

 narrow. Maxilla? short, with few but strong spines along- 

 inner margin. Palpi truncate at apex ; last two joints of 

 labials about equal, penultimate bisetose, apical somewhat
