156 SPOLIA ZEYLANICA. 
female are not visible on the male, 7.e., the spots on the first and — 
second abdominal segments, the lines bordering the inner orbits 
and branching in above the ocelli. 
Length, 74 mm. 
Habitat: Female, Oddichudan, Ceylon, N. P., Nov., 1908 (O. S. 
Wickwar). Male, Anuradhapura, Ceylon, N.C. P., Nov., 1908

This species would come next to O. diffinis in Bingham’s Key 
(‘‘ Fauna of British India, Hymenoptera,” Vol.I.). 
I have pleasure in naming this species after Mr. O. 8. Wickwar, 
who has done so much to further the study of Aculeate Hymenoptera 
in Ceylon.
