 black colour. It is much the rarest of the three. T. stigmata is the 

 only described species of the genus having a male sexual mark on the

[The notes are taken so far as possible from the original descriptions 

 or from Stal, Signoret, Butler, or Distant, &c. where these writers have

 Museum have been converted into millimetres from the recorded measure- 

 ments of the several authors.]

In 1874, Mr. Butler of the British Museum (Cist. Ent. i. p. 245) 

 recorded the species of the genera Gosynoscarta and Thymatostetha, 

 formed by Stal from the genus Gercojpis of Walker {nee Fabricius). He 

 enumerated 104 species of the genus Cosmoscarta and 22 sjjecies of the 

 genus Phymatostetha. Since then, the number of species of the genus 

 Cosmoscarta has been increased by eight of which five, described by Mr. 

 Distant, come from India and the Eastern Archipelago, and three, de- 

 scribed by Mr. Butler, come from Penang and Sumatra. The number
