PLATYLABIA. 125 



The colour is invariably bright orange or black ; these two 

 shade into one another insensibly or interchange, and so no 

 weight can be attached to colour in this genus. 



At first glance the single known species of Palex closely 

 resembles this genus, owing to the black and chestnut coloration, 

 build, and strongly depressed body. 



The genus needs revision and a thorough comparison of types.

Burma: Karen-ni, Keba District, 3000-3700 ft., April to 

 December {Genoa Mus.) ; Ceylon {Brussels M us.). 



According to de Bormans, this species is distinguished by the 

 short pygidium of the male, which is not very prominent. It is 

 recorded from Ceylon (Brussels Mus.), but the identification is 

 doubtful ; it is also recorded from Celebes and from Java. 



75. Platylabia gestroi, Duhr. 



Platvlabia gestroi, Dubr. (79) p. 372, fig. in text : Borm. (88) p. 436,

Relatively large, with dense dark pubescence. Antennae with 

 13 segments, the eight basal segments brown, the rest yellow ; all 

 cylindrical. Head black, posterior margin somewhat emarginate, 

 sutures indistinct. Pronotum black, nearly as wide as the head 

 and a little longer, posterior margin gently rounded ; prozona 

 tumid, sides and metazona flat. Elytra twice as long as the pro- 

 notum, black, finely punctulate, truncate posteriorly. Wings 

 long, of the same colour and consistence as the pronotum. 

 Femora fairly stout; legs yellowish, varied with fuscous. Abdo- 

 men reddish chestnut. Last dorsal segment ample, broader than
