The species here regarded as schultzei can be divided into two distinct colour 

 forms, the dark ' schultzei-iorm ', and the pale ' sulphurea-form '. In many collec- 

 tions made by the author in Sudan these two colour forms have been taken in the 

 same flowers. This is also true of collections made in Kenya and Uganda. The 

 pale forms have been compared with pale ' F. dampfi ' from Egypt and ' F. sul- 

 phured ' from India, and the dark forms have been compared with ' F. interocellaris ' 

 from Uganda, and schultzei (det. J. C. Faure) from South Africa. Apart from 

 colour, no other morphological differences have been found between these two 

 forms. It has been suggested that sulphurea can be separated from schultzei on the 

 shape of the base of the internal trichome on antennal VI. In all the material 

 examined by the author in this group this trichome had an elongate base, no speci- 

 mens were seen with a circular base to the trichome. The situation with regard to 

 this species in East Africa and the Nile Valley appears to be similar to that of the 

 colour variants of Frankliniella occidentalis in California (Bryan and Smith, 1956).

Frankliniella setipes Bagnall

This species is very close to fulvipes Bagnall from which it differs in having the 

 tibiae uniformly brown contrasting with the yellow tarsi.
