SELIDOSEMIDAE. 

 SiSYROPHYTA, gen. nov. 



Face with tuft of scales. Tongue developed. Antennae in $ bipectinated, simple 

 towards base and on apical third. Palpi rough-scaled. Thorax hairy beneath. 

 Abdomen in $ elongate, hairy beneath. Femora glabrous, posterior tibiae in $ 

 elongate, dilated, containing hair-pencil in groove, posterior tarsi in $ reduced. Fore- 

 wings in $ without fovea, more or less distorted, above with longitudinal supramedian 

 groove, beneath more or less largely clothed with dense rough hairs ; 10 sometimes out 

 of 9, sometimes connected with 9, 1 1 sometimes out of 10 near base, sometimes running 

 into or anastomosing with 12. Hindwings in $ above with median groove or streak of 

 erect hairs. 



Remarkable for the curiously developed secondary sexual characters of the $. 

 The two species have much general similarity ; the $s are obviously distinguished 

 by the differences in these secondary sexual developments ; the $s may be separated by 

 the difference in size and neuration. Type S. gomphias.
