The female sometimes has orange and sometimes wliite 

 markings, but whether seasonally or not there is no evidence 

 to show.

Bourou. 



Allied to T. zarinda. The type should be in Hewitson's 

 collection, but was probably not in good enough condition to 

 induce him to retain it.

This species varies a good deal both in depth of colour 

 above and below and in dusky veining and clouding. T. thyria 

 and T. figulina are both separable as varieties, but whether 

 they ai*e seasonal forms or mere sports remains to be dis- 

 covered.
