This species has been placed in the genus Alcinms, and so 

 appears in Kertesz's Cat,, doubtless owing to the remark by 

 Wiedemann that the transverse vein is very near the base 

 of the first subraarginnl cell, which is true ; but it is hardly 

 as close as in species of Alcinms, and the species has all 

 the appearance and characters of the genus Philodicus, to 

 which it certainly belongs, though Schiuer states that one 

 female he saw in the Winthem Coll. belongs to the genus 

 Alcimus. The specimens in the Brit. Mus. Coll. from 

 Ceylon answer to Wiedemann's description, his specimens 

 came from Tranquebar, and Roder records it from Ceylon. 

 The genus Alcimus is, therefore, practically confined to the 

 African Region. 



In the Brit, Mus. Coll. are males and females from 

 Trincomalee and Mahagauay, Ceylon (Yerbury Coll.).
