side of the thorax beneath the wing and may easily be overlooked, 

 but when spread out it is very noticeable, appearing like thistle- 

 down at the base of the costa. The occurrence of this character in 

 both sexes may suggest a different train of thought to those who 

 have enunciated various theories to account for the functional 

 utility of such structures hitherto observed in the male sex only. 



This observation is founded on the examination of many speci- 

 mens belonging to several described and undescribed Transatlantic 

 species.

 outwardly oblique costal streaks, and at the outer end of the cell 

 in an inwardly curved line of which the lower extremity reaches 

 the upper angle of the somewhat indistinct ocelloid patch (con- 

 taining two black dots set in rosy-white preceded by a steel-grey 

 shade); some oblique slender steel-grey lines extend nut wards I nun
