CARABIDAE FROM BURMA 335 



163. Amblystomus punctatus, n. sp. 



Oblongus, cupreo-aeneus nitidus, toto sparsim subtiliter punc- 

 tulatus, thorace quoque ruguloso; antennis articulo basali, palpis 

 apice tibiisque flavo-testaceis. Caput magnum baud vero conspicue 

 abbreviatum , epistomate profonde arcuatim emarginato , baud 

 perspicue asymmetrico; mandibulae normales. Thorax minus 

 transversus, antice perparum rotundatus, deinde usque ad basin 

 angustatus, angulis posticis obsoletis. Elytra striata, striis versus 

 suturam profundis. — Long. 4 mill. 



Mandalay. 



There is one example only of this well-marked species. In 

 its punctuation it resembles, according to the description, A. {Me- 

 garisterus) mcmdibularis ^ Nietner. 



164. Amblystomus tetrastigma, n. sp. 



Ab A. vulnerato, Dej., differt tantum elytris utrinque maculis 

 duabus fulvo-rufis. 



Bhamò ; Teinzò ; Rangoon ; Palon (Pegu). 



An elongate oblong species 4-5 Ya millim. long (2 V2 lignes, 

 Dej.) dark brassy-black, the basal joint of the antennae, palpi 

 and legs reddish-testaceous. The head is moderately large, the 

 left mandible exserted and overlapping the apex of the sinistral, 

 the episteme asymmetrically sinuate-emarginated. The thorax is 

 broad and short (but varying a little in width) strongly rounded 

 on the sides from the apical angle to the base, the hind angles 

 being scarcely indicated. The elytral striae are more feebly im- 

 pressed towards the sides, the posterior spot lies on interstices 

 3 to 6 (sometimes confined to 4-5), the anterior spot on inter- 

 stices 5-6. I can detect no difference in form or sculpture between 

 this and Indian examples of i4. vulneratusj Dej.; it seems there- 

 fore highly probable that it is a variety having a sub-basal red 

 spot in addition to the subapical one. In some examples the red 

 spots are very faint, the anterior less defined than the posterior. 



The species does not differ from A. femoralis except in the 

 unicolorous legs and the spotted elytra and individuals exist in 

 which the femora are a little fuscescent.
