GENERA OF AFRICAN LYCAENIDAE 221 



confusing. The penis of all has the same characteristic form and has the carina 

 penis and cuneus typical of the genus. References to figures of genitalia are included 

 in the list of species given below. 



It is worth noting that, whereas most of the species of Syntarucus are widespread 

 throughout Africa and often found flying together, five have very restricted distribu- 

 tions. These are S. socotranus, found only on Sokotra, S. rabefaner, restricted to 

 Madagascar, S. terrenus in Sao Thome" and mayottensis and casca of the Comoro 

 Islands. In the description of Cyclyrius I have already called attention to the close 

 affinities existing between that genus and Syntariicus and the American genus 

 Leptotes. 



The early stages of pirithous have been described by Murray (1935 : 190). In S. 

 Africa the caterpillar feeds on various species of Leguminosae, e.g. Plumbago capensis, 

 Burkea africana, Indigo/era spp., Mundulea sericea and Medicago sativa L. (Legu- 

 minosae). Recently Mr. K. M. Pennington has informed me that at Delagoa Bay the 

 caterpillar of pulcher feeds on Sesbania sesban.
