M. dermaptera, male genitalia (Text-fig. 101). Uncus well developed, trapezoidal, posterior 

 edge deeply notched ; subunci long, curved, uniformly tapered ; tegumen large, united to the 

 uncus by a lightly chitinized zone ; vinculum broad ; lower fultura with small curved arms ; 

 valves small compared with the dorsal structures, oblong, the edge of the lower process slightly 

 serrated before the apex which has the shape of an open hook ; penis as in M. silenus ; a few 

 hairs on the uncus and on the distal portion of the valves. The male genitalia of M. subornata 

 are identical with those of M. dermaptera ; again I think that they are perhaps two races of the 

 same species. The armature of M. sharpei differs from that of dermaptera only in its shorter 

 and more curved penis. 



The early stages of Myrina are fairly well known. The caterpillars of M. silenus 

 and M. subornata have been described by Farquharson (1911, Trans, ent. Soc. Lond. 

 1911 : 99) ; Lamborn (1913, Trans, ent. Soc. Lond. 1913 : 472) and by Jackson 

 (1937, Trans. R. ent. Soc. Lond. 86 : 212) ; those of M . ficedula and M. dermaptera 

 by Murray (1935 : 14, 66, fig. 18) and Pinhey (1949 : 101). They feed on wild and 

 cultivated Ficus ; they possess dorsal glands and are tended by ants of the genera 

 Camponotus and Pheidole.
