a88 NYMPHALID^. MORnilN.^. AMATHUSIA. 



ocellus next the costa is \ety much larger and more distinct than that near the anal angle. 

 The FEMALE of this species (represented in the Gen. D. L., plate Hi, fig. I, as the female 

 of Z. luxerii) has the outer half of both wings tinged with a blue gloss, with an oblique 

 bluish-white broad bar extending from the middle of the costa to the third branch of the 

 median nervure, where it is broken up into three rows of spots ; the interior conical, 

 the middle row nearly rounded, and the outer ones semicircular. There is a slight trace of 

 these spots continued along the outer half of the hindwing." (IVeshvood, 1. c.) 



The woodcut which accompanies represents the female of Z. douhledaii, and is copied 

 from the figure in the Gen. D. L. It is doubtful whether this species does really occur in 

 India, in any case it is extremely rare ; we have never seen a specimen. 



The four species of this genus referred to above are all very closely allied, and appear 

 to differ mainly in the tone and character of the blue markings on the upperside in the males. 



Z. viasoni has the blue patch on the hindwing extending from the anal margin nearly up 

 to the discoidal nervule. 



Z. atuethystus has the patch extending from the anal margin to the fold in the second 

 median interspace only, 



Z. luxerii has the patch lilac, and at the outer angle only, 



Z. doublcdaii has the patch blue, and extending from the outer angle to the anal angle.

" Body rather small, very hairy. Head rather small [in A. fhidippus, large mA.foit/ieiis], 

 hairy, with a small, frontal, conical tuft of hairs ; neck short. Fal/yi rather slender and com- 

 pressed, porrected obliquely to about the length of the head, and raised at the tip nearly 

 to the level of the top of the eyes, not united into a conical beak, scaly beneath ; the back 

 of the second and third joints hairy, the hairs of the middle joint being erect, and resting 

 on the front of the face and side of the frontal tuft ; terminal joint ovate-conic. [In A. portheus, 

 the palpi are erect, and rise in front considerably above the level of the top of the eyes.] 

 Antennce about three-sevenths of the length of the forevving, slender, not straight ; the 

 joints very distinct ; club long, very gradually formed, and very slender, finely carinated 

 beneath, articulations distinct, the terminal ones gradually acuminate. Thorax ovate, very 

 hairy, neither large nor robust. WiNGS large, hindwing with two ocelli wide apart on the 

 underside. Forewing large, elongate-triangular, costa very much arched, apex rather rounded, 

 vuter margin about two-thirds of the length of the costa, entire, slightly concave ; hinder 

 angle rounded, inner margin nearly straight, rather narrowed towards the base. Subcostal 

 nervure slender, the first branch nearly at the distance of one-third of .the wing from the 

 base, extending to the costa at about three-fourths of its length ; second, third and 

 fourth branches arising close together at about three-fourths of the length of the wing ; the 

 second and third very short, joining the costa ; the fourth longer, extending to the tip ; 

 the remainder of the nervure extending to the apex below the tip. Upper disco-cellular 

 nervule arising from the subcostal at about two-fifths of the length of the wing, extremely 

 short and oblique ; middle disco-cellular twice its length, and transverse ; loxver disco-cellular 

 very long, strongly angulated in the middle, the anterior part continuing in the same line as 

 the middle disco-cellular, the posterior part very oblique, uniting with the median nervure 

 at a distance from its base equal to half the distance between the bases of the first 

 and second branches of the median nervure, thus closing the discoidal cell in an acute 

 point at nearly half the length of the wing ; the third median nervule beyond the 

 junction much arched, or rather angulated, at about the same distance beyond the junction 

 as exists between the first and second median nervules. HiNDWiNG subtriangular, costa arched, 

 apex rounded, outer viargin with wide but not deep scallops, anal angle produced into a 

 broad short tail [in A. phidippus, but into a much longer and narrower one in A. portheus\ 

 extending between the extremity of the first branch of the median nervure and the 

 submedian nervure. The prcccostal nervure is curved at its tip towards the body.
