MALAYAN ANTHRIBIDAE 635 



to L. dorsalis (1894), I am not yet prepared, on account of the 

 absence of the abdominal tubercle in the </", to regard it as a 

 mere local form of dorsalis.

The fulvous markings on the elytra are somewhat larger 

 than in typical specimens from Perak. There is in Perak and on 

 Mentawei another closely allied form , differing from humeralis 

 in the eyes being less prominent and wider apart, and in the 

 angle of the prothoracic carina being more rounded. 



33. Litocerus mentawensis, spec. nov. 



9 . L. moesto sÌ7nilis, major; rostro fortius ruguloso-pimdato^ 

 carinulis melius expressis, antennarum arliculo 8° nono plus di- 

 midio breviore; prothoracis et elytrorum maculis multo majoribus 

 ac magis lulosis distinguendus. 



The tomentum is clay colour, not white and on the upperside 

 much more extended than in L. moestus, though the arrangement 

 of the spots is nearly the same as in that species ; the elytra 

 bear a spot on tlie suture before the middle, another in the 

 middle on the disc which are slightly larger and less linear than 

 the other markings. In one of the two specimens the lineolae 

 at the base of the elytra are more or less merged together.
