CARABIDAE FROM BURMA 407 



Karin Gheba, alt. 900-1100 m.; Karin Gliecù alt. 1300-1400. 



Two examples, agreeing very well with Schmidt-Goebel's de- 

 scription in regard to the remarkable form of the thorax, whicli 

 is broader behind than before, with porrected anterior, and 

 rectangular hind, angles, and in the two depressions on the 

 sides of the elytra. The margin of the elytra has no trace of 

 denticulation, and the eyes are only moderately prominent; but 

 the species has not the facies of tliose which constitute the 

 restricted genus Thyreopterus in Chaudoir's monograph.

The species has been previously recorded only from Sarawak 

 (Borneo). 



380. Sinurus nitidus, n. sp. 



S. opaco paullo minor, niger nitidus, elytris subtilissime alu- 

 taceis, antennis partibusque oris melleo-rufis, genubus tarsisque 

 obscure fulvo-piceis. Caput breve mox post oculos et cite angu- 

 statum subtilissime alutaceum, fronte juxta oculos pluristriata ; 

 oculis valde prominentibus. Thorax quam in S. opaco brevier 

 magis cordatus angulis posticis baud porrectis lateribus antice 

 rotundatis apud porum setiferum anteriorem leviter angulatis, 

 postico sinuatis angulis posticis obtusis (margine basali versus 

 angulos obliquato), margine laterali explanato-reflexo , postico 

 altieri; supra subtilissime strigulosus. Elytra breviter oblonga 

 (angulis rotundatis) apice sinuato-truncata apice suturali sub- 

 rotundato; subpunctulato-striatis , interstitiis convexis, 3.^*^ post 

 medium bipunctato; margine laterali explanato reflexo, rufe- 

 scenti. Subtus medio piceo-fulvus. — Long. 8-9 millim. 



Karin Gheba, alt. 900-1100 m.; Ascimi Gheba, 1200-1300 m. ; 

 Karin Ghecù, 1300-1400 m. 



The tarsal claws have four denticulations at their base, as in 

 Sinurus opacus; but the lateral margin of the elytra bears no 

 trace of denticulation.
