All immature specimen without locality label, apparently belongs to 

 the same species. 



This form differs from P. americana, L., by its darker chestnut tint, 

 by the pronotum being almost uniform in colour, and by the tegmina only 

 slightly exceeding the abdomen. 



Total length ($) 31 mm.; body 28 mm,; pronotum 9X^2 mm,; teg- 

 mina 24 mm. 



Originally described by KRAUSS from Teneriffe, Brazil and New Britain, 

 Rehn recorded this species from Batu Sangkar, Padangsche Bovenlanden, 

 Sumatra. Though now again recorded from Sumatra, it is curious that it 

 has not yet been taken on the Malay Peninsula. The 0. U. M. has spe- 

 cimens from Phuc Son (Annam) and Ecuador.

Brunner described this species first from the Nicobars, and later on 

 from Baram, Borneo '). Rehn recorded it from Trang, Lower Siam; Shel- 

 FORD collected it in Kuching, Sarawak (specimens in the O. U.M.), and 1 took 

 it in the Botanic Gardens, Singapore, from under dead tree trunks (spe- 

 cimens now in the Raffles Museum).

 Brunner's type, viz.

 Brunner's: body (7) 25 mm; pronotum 7.5X9 mm; tegmina 3.5 mm.
