CARABIDAE FROM BURMA 401 



362. Orthogonius? 



Bhamò. A single example. 



363. Orthogonius Baconi, Chaud., Ann. Soc. Ent. Belg., XIV, 

 p. 109. 



Bhamò. 



Two examples, agreeing fairly well with the above-cited 

 description and presenting the same differences from 0. fugax 

 (Chaud.) from Southern India and Ceylon with specimens of 

 which I have compared the Burmese insects ; in these, however, 

 the margin of the presternum is not distinctly carried round 

 the apex. Chaudoir's examples come from Bengal. 



364. Orthogonius angulatus, Schmidt-Goebel, Faun. Birm., p. 58. 

 Karin Chebà, alt. 900-1100 m. Two examples. 



A species omitted from Chaudoir's " Essai Monographique. " 

 It is of similar form to 0. punclicolUs but smaller and distin- 

 guishable at once by the very obliquely truncated elytra, the 

 outer angle of the truncature slightly produced (broadly den- 

 tiform) the suturai angle acute. It does not come within any 

 of Chaudoir's subdivisions of the genus but is nearest the group 

 which includes 0. Hopei and 0. acrogo?ius„ being distinguished 

 from it by the elongated antennae. The elytral interstices 1-6 

 are of subequal widths the presternum immarginate, the outer 

 angle of the anterior tibiae produced, the fourth joint of all the 

 tarsi bilobed and the claws pectinated. The depressions of the 

 anterior part of the head which offer good specific characters in 

 this difficult genus are very different from those of 0. puncticoUis 

 and allies, the centre of the episteme having a large and deep 

 fovea and the sides of the forehead being bi- or tricarinate and 

 the frontal furrows broad, deep and rugose.
