 meter of eye. Occiput yellowish brown. Orbitals nearly equally distant from eye margin ; 

 anterior reclinate orbital minute, not distinguished from neighbouring hairs, slightly nearer to 

 proclinate than to posterior reclinate. Proclinate orbital slightly shorter than posterior reclin- 

 ate. Postverticals long. Two long subequal orals, succeeding orals much shorter. 



Mesonotum glossy pale yellowish brown, medially and laterally with obscure fuscous patches.
