corresponding lunnlo of the lino next it on the inner sitle, so that in each 

 interspace the two touching lines of Innules seem to form a series of mark- 

 ings like X'", which is characteristic of the species. 



Lana. — In s/nijx' this larva is somewhat abnormal and rather like that 

 of Arhopala ceutaurus. The breadth gradually increases from segment 3 to 

 segment 10 after which it decreases again to the anal end which has 

 the extermity semi-cireularly ronnded rather broadly ; these last segments 

 12-14 being llatteiied dorsally with the slope at abont 30^ to the longitu- 

 dinal axis of the body : there is, however, nowhere any very great difi'er- 

 enco in breadth : the highest part is about segments 7-9 (varies with the 

 position the larva assumes ; this being the normal one when it is neither 

 stretched nor contracted) ; the segments are not anywhere constricted ; 

 the head is hidden under segment '2, is small, nearly round in shape, shiny 

 green or greenish yellow in colour ; segment 2 is rather small, nearly semi- 

 circular in shape, th<iugh somewhat produced in front, rather abnormally 

 convex transversely, slightly constricted at hinder margin, stretching far 

 down laterally and with no sign of a dorsal depression — another abnor- 

 mality. Sur/acf inclined to be greasy-looking, the segmental margins 

 nowhere well defined ; a central dorsolateral depression on segments 

 4- 0, the segments sightly shallowly corrugated on sides, a depressed line 

 above each spiracle and a dorsal, transverse depression on segments 3, 4 ; 

 the whole body covered with minute, round, white tubercles ; the margins 

 of segments - and 14 very sparsely and shortly haired ; the gland on 

 segment, 11 large, transverse, mouth-shaped ; the organs on segments 12 

 small, circular, white, inconspicuous. tSjiiracles small, flush, round, white, 

 situated on the very margin of the subspiracular, yellow (yellowish green 

 in some specimens) band. Colour either dark rose or grass-green ; when the 

 latter, the sxibspiracular band is yellowish green, bordered above and below 

 by a yellow line ; this band about .|rd the breadth of the body, the gland rust- 

 pink as well as the surroundings for a short distance ; when rose-coloured 

 there is a broad, spiracular, yellow band and a lateral, narrow yellow band 

 both curving towards the gland on segment 12 at the ends ; and there is 

 dark, dorsal line on segments 7-9 ; segment 2 has a dorsolateral, green, 

 longitudinal mark or band on each side of dorsal line in continuation of 

 the general body pattern ; the markings or pattern of this larva recall those 

 f Arhopala cPiitaurus very inuch ; the belly or ventrum is dark green. 

 L : 15 mm.; B : 2*o mm. at segment 2, 4 mm. at segment 10. 



Pupa. — More or less normal in shape except as concerns the anal segment 

 which is here dilated to resemble a horse's hoof though not very accentua- 

 tedly so — in which, as in the larva, this species resembles Arhopala centau- 

 ries ; — with its surface absolutely at right angles to the longitudinal axis 

 of the pupa instead of being turned under as in the majority — nearly all — 

 lyctenines ; front margin of segment 2 square in front, slightly concave 

 perhaps along margin — semi-circular in, outline on the whole — hiding the 

 head from above ; the head with frons fully exposed and not bent 

 under, rather high ; segment 2 very convex transversely, its dorsal 

 slope in the same plane as that of the anterior part of thorax ; this 

 latter humped a little, transversely convex, its apex being the highest 

 part of the body ( or, perhaps it is segment 7, for there is very little 

 difference, if any), the apex slightly depressed, the dorsal line obscurely 

 thin-carinate, its hinder margin produced rather far back in dorsal line, 

 very nearly triangularly, leaving the segment 4 more than usually 

 exposed and long, especially laterally because of the broad, rounded, deep 

 angle at which it meets the wing lines ; constriction behind thorax very 

 slight, the dorsal outline of abdomen only slightly convex, the ventral 

 line of pupa straight. -"Surface pupa is slightly shining and covered all over
