MEYRICK— TORTRICTNA AND TTNEINA 303 



much mixed with black dorsally. Abdomen grey. Forewings elongate, costa gently 

 arched, apex obtuse, termen obliquely or very obliquely rounded ; white, somewhat 

 sprinkled with fuscous, in one specimen tinged with fuscous ; markings black ; costal 

 edge black towards base ; a variable spot on base of costa containing a white spot ; 

 an irregular mark from costa about £, sometimes interrupted, preceded and followed 

 by one or two variable costal dots ; a narrow irregular inwardly oblique transverse 

 median fascia, expanded dorsally, sometimes interrupted in disc ; a more or less developed 

 inwardly oblique mark from costa at f ; an irregular streak along termen, rather 

 triangularly dilated on tornus, sometimes rather widely interrupted above this, or 

 forming a series of cloudy dots, sometimes extending round apical part of costa ; in one 

 specimen apical area largely suffused with fuscous : cilia white, sometimes variably 

 sprinkled with dark fuscous on basal half, at apex and beneath tornus with grey spots. 

 Hindwings light grey with brassy reflections ; cilia whitish. 



Mahe, near Morne Blanc and Cascade Estate, 1000 feet; Silhouette, Mare aux 

 Cochons plateau, 1000 feet; from September to December, seven specimens. There is 

 great variability in development of dark markings and fuscous suffusion, and the shape 

 of forewings also varies somewhat, but I am unable to separate any of these forms 

 specifically. I have also six worn specimens taken by Mr T. B. Fletcher from Siren 

 Island in the Cargados group of the Carajos Islands, which I refer to the same species.
