 New synonymy? 



Ogcodes clavatus, Sabrosky, Proc. Roy. Ent. Soc. London, vol. 19, p. 51, 1950., 



Type locality: Africa: British East Africa, clavatus; Mt. Meru, 

 cepisetis; Nyasaland, nyasae; and East Africa, crassitibialis. 



Discussion: This species belongs in gi'oup v. Sabrosky (1950) 

 has given a good account of the variation occuiTing in clavatus. In 

 examining part of his observed series of clavatus, as compared to the 

 original description of crassitibialis Brunetti, I conclude that the latter 

 species is very likely a synonym of clavatus. 



Although clavatus is surely a member of the pallidipeniiis group, 

 the male genitalia show it to be set apart somewhat from all other 

 species of the group (see pi. 8, fig. 48, pi. 13, fig. 110). The wing 

 also shows a definite group relationship; however, it is one of the few 

 species seen that has the r-m crossvein perpendicular to the costa 

 (see pi. 3, fig. 10). 



The relationships of clavatus to other species are not fully under- 

 stood, but colorwise it resembles guttatus Costa. However, the latter 

 is a member of the eugonatus group and is therefore not closely related 

 phylogenetically. Perhaps such species as congoensis, neavei, and 

 trilineatus (all Brunetti, 1926) will be found to be associated species. 



Specimens examined: 



East Africa: 5cf, Naivasha, Kenya, July 1937, September 1939, and April 

 1940 (H. J. A. Turner, USNM, EIS). 



Ogcodes species of Oriental region 



The eight species hitherto recorded from this region are: angusti- 

 marginatus Brunetti, juscus Brunetti, lineatus Brunetti, margini- 

 fasciatus Brunetti, octomaculatus Brunetti, respersus Sequy, rufo- 

 marginatus Brunetti and sexmaculatus Brunetti. All of these species 

 except the Chinese respersus were described from either India or 

 Cej^lon. The name octomaculatus Brunetti is herein synonymized 

 with guttatus Costa (see discussion under guttatus). To this list of
