Mr. W. C. Hewitson on some new species of Butterflies. 263 



the trifid spot between it and the subcostal nervure is whiter and 

 more distinct ; that the portion of it which touches the median 

 nervure, which in the last species is deeply sinuated and crescent- 

 shaped, is here round and entire; that the fulvous band near the 

 tip of the upper wing is composed of six divisions, the two lower 

 of which are large, forming together a triangle which is only se- 

 parated from the first two segments of the white band by a black 

 line ; and that the fulvous lunular spots of the under wing are 

 wanting. Expansion 2 inches 4 lines.

Also closely allied to H. Corcyra, but differs from it in that the 

 white band commences on the upper wing by an oval spot, does 

 not meet equally at its edges in passing from one wing to the 

 other, and is curved inwards on the lower wing, where it termi- 

 nates at the anal angle in the form of a hook ; that in the place 

 of the fulvous spots of the upper wing is a broad red band of 

 equal breadth, which crosses the whole wing parallel to the pos- 

 terior margin and the white band, from which it is only separated 

 by a line of brown ; that the fulvous lunular spots of the lower 

 wing are wanting, and that the underside is much lighter. Ex- 

 pansion 2 inches 2 lines.

Heterochroa Arecosa. PI. XXI. fig. 12. 



Upper wings long and slightly sinuated, under wings deeply 

 dentated with a short tail, light brown with a central band of 

 white common to both, commencing at the subcostal nervure of 

 the upper wing — between which and the margin is a small oblong 

 white spot — and extending to the anal angle of the lower ; broken 

 at its commencement into four distinct spots, the first oval and 

 distant from the rest, the second rounded and nearer, the third 

 and fourth oblong and touching, the rest distinctly intersected 

 by black nervules, the last segment at the anal angle triangular 

 and divided from the rest. Parallel to the margin of the upper 

 wing are two waved lines of dark brown, and also the five black 

 lines across the cell ; the space between the middle line which is 

 very straight, and the next within it which is curved, is red as well 

 as the humeral angle. Parallel to the margin of the lower wing 

 is a waved dark brown line, and within it six large nearly round 

 spots of the same colour ; at the anal angle is a large irregular 

 rufous patch, and in its centre two indistinct dark spots. 



Underside light and indistinct ; the central band crosses the 

 entire wing unbroken; the marginal lines are white; a rufous band 

 crosses the cell of the upper wing, and another marks the posi-
