434 Mr. H. Grose Smith on new Batterjlies from Borneo. 



the centre by a concave brown fascia, as in P. hathycles^ but in 

 lieu of it there is a short, narrow, brown fascia from the costa 

 nearly as far as the subcostal nervure, almost divided on the 

 costal nervure by a small orange-red spot, and there is a small 

 triangular silvery spot next the cell between the upper and 

 second discocellular nervules. The dark brown area in 

 which the series of orange-red spots towards the anal angle is 

 situated is broader than in P. hathycles, and the submarginal 

 row of spots is further from the margin. 

 Expanse of wings 2^ inches. 



Papilio macaristus. 



Near to P. macareus, Godart, but differs from it in the fol- 

 lowing respects : — Anterior wings : upperside, in place of the 

 double row of three spots and three short bars in the space be- 

 tween the end of the cell and the upper part of the submarginal 

 row of spots, there are three elongated streaks, slightly clavate at 

 the ends nearest the cell. On the posterior wings the streaks 

 in the area between the cell and the exterior margin are very 

 short and narrow. Underneath, all the streaks on the posterior 

 wings are very indistinct, some being almost obsolete, 

 while in P. macareus they are quite as large and distinct as on 

 the upperside ; the body is black, with a narrow grey stripe 

 on each side. Two specimens of P. macareus in my collection 

 Irom Sumatra have bright brown bodies, and two others from 

 Darjeeling have black bodies broadly striped with grey. 



1 should have been disposed to look upon this insect as a 

 variety only of P. macareus if there had not been in the collec- 

 tion a uniform series of it from the same locality. 



Expanse of wings 3^ inches. 



Appias Whiteheadi. 



Male. Above, approximates to A. pandione, Hiibn., but on 

 the anterior wings the apical area is more extensively black, 

 and in place of the large subquadrate black spot at the end of 

 the cell oi A. pandione^ which is contiguous with the greyish- 

 black costal area, there is a small black spot quite distinct. 

 The second submarginal white spot in the middle of the apical 

 area is almost obsolete. On the posterior wings the black 

 margin is double the width of that oi A. pandione, extending 

 over the exterior third of the wings. Below, it differs from 

 A. pandione on the anterior wings in the spot at the end of 

 the cell being very small and distinct, and the apex being 

 jiinkish grey. On the posterior wings the basal third is light
