Mr. H. E. Andrewes on Oriental Carabidse. 295 



Oz^ENINI. 



Before describing any new species I give a table of the 

 Oriental genera : — 



1 (4). Ligula bisetose or ending in a sharp 



spine, last joint of palpi cylindrical, 

 genie embracing back of eye, mentum 

 toothed, joint 11 of antennae shorter 

 than 9 + 10. 



2 (3). Ligula ending in a sharp spine ; para- 



glossia wide, with setose margins, ex- 

 tending fur beyond ligula, but not' en- 

 veloping it; genas forming a tooth and 

 extending outwardly beyond level of 

 eye*; mandibles with three or four 

 teeth ; both labium and clypeus with- 

 out setae on upper surface Pseudozjena, Cast. 



3 (2). Ligula bisetose, completely enveloped by 



the paraglossae, which are glabrous; 

 geme not extending outwardly beyond 

 eye-level ; mandibles with one or two 

 teeth ; front margin of labrum pluri- 

 setose (8-setose in /. castaneus, Schm. 

 Goeb., and 12-setcse in /. dentatus m.) Itamus, Schm. Goeb. 



4 (1). Ligula quadrisetose, paraglossia wanting 



(or at all events indistinguishable), last 

 joint of labial palpi acuminate, genae 

 not embracing back of eye, joint 11 of 

 antennae equal to or longer than 9+10. 



5 (6). Mentum with an obtuse tooth ; front 



margin of labrum plimsetose but not 

 denticulate (8-setose in I). biotulata m. 

 and 6-setose in D. parallela m.) ; joint 

 11 of antemue = 9+10 Dhanya, gen. nov. 



6 (5). Mentum edentate ; front margin of labrum 



plurisetose and denticulate (8-setose 

 mE, plagiata, Schm. Goeb. ,E.japonica, 

 Bates t, and E. matanga m., 10-setose 

 in E. bnjanti m.) ; joint 11 of antennae 

 = 8+9 + 10 '. '. . . Eustra, Schm. Goeb. 



Itamus dentatus, sp. n. 



Length 15 0-1 7'5 mm.; width 4- 0-5*0 mm. (The further 

 measurements given are those of the larger specimen, which 

 is the type.) 



* Of P. spissicornis, Fairm., of which I have not seen an example, its 

 author says " tuberculo pone-oculari nullo." Mr. Lf sne (Mission Pavie, 

 1904, 62, t. 8. f. 13) says that the species belongs to another genus. 



t In Ann. Soc. Eut. Belg. 1913 (published 2.1.1914), p. 418, Com- 

 mandant Dupuis says that in E.japonica, Bates, joint 11 of the antennae 

 =9 + 10. 1 have numerous cotypes before me and find that 11 = 8+9+10 

 as in the other species of this genus.
