certain lights, and wliicli are traversed with black nervures. 

 These bands cross the wing, running into the anterior margin, 

 which is lined with the same brilliant colour, leaving a triangular 

 patch at the base, a central oblong transverse space, and a gra- 

 dually diminishing band, broadest at the apex, along the external 

 margin, of the ground colour. Posterior wings rather narrow and 

 terminated with a short blunt somewhat diverging tail ; above 

 purplish black, the tail and external margin purj)li^h blue in cer- 

 tain lights, wiih a narrow crimson band in continuation of the 

 crimson band of tlie anterior wing, running across the middle of 

 the wing nearly parallel with the outer margin, and suddenly 

 bending upwards and gradually vanishing a little below the apex 

 of the abdomen before it reaches the anterior margin. Behind 

 this band, and midway between it and the tip of the tail, is a long, 

 narrow, rather wavy, crescent-shaped patch of crimson colour, 

 nearly crossing the base of the tail, curving upwards before it 

 reaches the outer margin, where it runs into an obsolete bluish 

 band which passes alongside the margin and nearly midway be- 

 tween it and the crimson band ; on the outer margin are four 

 specks of white in the indentations, and two more in like situa- 

 tions at the tip of the tail ; below velvety black, with the base 

 and anterior margin of the same shining blue as that on the un- 

 derside of the anterior wings, and a broad band of the same blue 

 colour on the outer margin, leaving a broad central band, a line 

 along the outer margin, and the interior margin of the tip of the 

 tail, of the ground colour. The blue base of the wing and band 

 of the same colour on the outer margin are crossed with black 

 nervures. Head, antennae, body and legs black, except the an- 

 terior pair, which are steel-blue.

The specimen described is a ^ , which strongly resembles Py- 

 rctas. Cram., but differs in the shorter and blunter tails, in having 

 the crimson bands of the upper surface of the wings narrower, 

 and in the disposition of the metallic blue bands and markings of 

 the underside of the wings. 



Enjcina Colubra, W. W. Saund. (PI. XI. fig. 12.) 



Tlie anterior wings are sharply pointed, with the outer margin 

 somewhat indented ; above black, with a rather broad crimson 

 straight band, crossing the wing from a point on the outer margin 

 a little within the centre and terminating near the centre of the 

 posterior margin, the band being somewhat broader at its termi-
