HISTERIDAE PROM BURMA 637 



is abbreviated behind and ends anteriorly at a point correspon- 

 ding to the end of the 5 stria. The pygidium is not bordered 

 and its outline is more semicircular than most Platysoma. 

 Bhamò, Birmania, two specimens. 



21. Platysoma birmanum, Mars. Mon. 1861, p. 151, t. 3, 

 nr. 11, fig. 1 1 . 

 semistriatum, Motsch. Bull. Mosc. II, p. 450, 1863 

 (Mars. Ann. Soc. Belg. 1870, p. 71). 

 Over 20 specimens are recorded from Bhamò and Shwegoo- 

 Myo in Birmania. 



22. Platysoma brevistriatum , n. sp. 



Ovato-parallelum, subdepressum, nigro-nitidum; antennis pedibus- 

 que rufo-brunneis; fronte concava,, stria integra antice recta; pronoto 

 lateribus punctato marginato, stria interna postice valide abbreviata; 

 elytris striis 1-3 integris , 4-5 et suturali abbreviatis; propygidio 

 trans versim impresso, punctato; pygidio basi punctato apice laevi; 

 prosterno haud strialo, lobo tenuissime punctulato; mesosterno mar- 

 ginato stria integra; tibiis anticis 4 dentatis, posticis 4-5 denticu- 

 latis. Long. 4 */ 4 mill. 



This species is similar in general outline to the last, but it 

 may be known from every other described Platysoma by the 

 thoracic stria. The lateral marginal stria cannot be seen from 

 above , as it lies underneath the disc , the internal stria is 

 complete behind the neck, angulate behind the eyes, but runs 

 down towards the base of the thorax only to the extent of a 

 little more than one third of its length. The shortened elytral 

 striae are arranged as in striatiderum Mars. 



Found at Bhamò and Shwegoo-Myo in Birmania. Two examples. 



23. Platysoma dufali, Mars. Abeille I, p. 310. 



Three specimens have been found at Thagatà in Tenasserim 

 and one at Bhamò in Birmania. I have found it at Singapore 

 and in Ceylon. Marseul records it from Malacca.
