MALAYAN ANTIIRIHIDAE 643 



Tlie head and rostrum are densely covered with a luteous 

 tomentum. The base of the prothorax is nearly bare of luteous 

 hairs except in front of tiie scutellum, while the middle line is 

 anteriorly more densely pubescent than the rest of the disc. On 

 the elytra the tomentum is nearly distributed as in nilidicutis, 

 but the basal, scutellar, dark space is less extended.
