28 ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 



Upper side of fore wing rich dark brown, nearly black. Towards the apical 

 and hind marginal areas the coloring becomes somewhat lighter, sufficient to 

 show a series of dark interspacial markings along the hind margin. Within 

 this, running from costa towards centre of hind margin, is another series of 

 similar dark markings, forming a band. Still nearer base, and crossing end of 

 discoidal space, is a suggestion of another dark band. These dark markings 

 are so indistinct in a fresh specimen that they would be seen with difficulty. In 

 worn or faded specimens they would, undoubtedly, be quite prominent. 



Upper side of hind wing very rich dark brown. From the upper angle to 

 anal angle extends a series of interspacial lighter dashes, following contour of 

 the margin, and above these, near end of discoidal space, are two slight dashes 

 also. These markings are almost too indistinct to warrant mention. 



Hind margins of both wings have a slight fringe of ground color. 



Under side of fore wing dark brown, but lighter and less rich than upper sur- 

 face. The suggestions of dark markings are repeated. Inner marginal area 

 a little lighter than balance of wing. 



Under side of hind wing the same dark brown, the lighter markings of upper 

 surface being repeated. The basal area has a few indistinct mottlings. 



A colored plate of a species like this is absolutely necessary for 

 anything approaching accurate identification. 



It may resemble Achlyodes castalus, Hew., but that has three sub- 

 apical light spots, which do not appear at all in this, and on close 

 inspection of the scale distribution on under side of hind wing con- 

 siderable difference will be noticed.

Head, palpi, thorax, abdomen, and legs dark reddish brown, lighter beneath. 

 Antennae dark brown, with white annulations at base of each joint, tip white

Upper side of fore wing rich blackish brown. Apex dashed with white. 

 Across discoidal space, near its end, is a prominent transparent white band or 

 mark, and below it in first submedian interspace, but nearer margin, is another
