wet months, is darker in shade than the dry-season specimens, and fresh 

 individuals of that form often have the puipHsh silvery markings bright 

 burnished steely blue in colour. The female also or the whole seems at all 

 times to be lighter in shade than the male, especially on the underside. 

 Exp. 56-77 mm. 



Larni. — The shape of the larva is cylindrical, the anal end rounded and high . 

 the body is set with seven longitudinal rows of spinous softish pedicels, one 

 of each row to each segment 3-l"2. The head is square from front view, the 

 face somewhat convex, divided into two lobes by a considerably depressed 

 central line ; surface covered with small white and yellow conical tubercles 

 bearmg each one hair, one tubercle on the vertex of each lobe being much 

 larger than the rest and yellow, bearing a long hair ; colour black- bronze with 

 the vertex reddish. Segment 2 is not much narrower than the head and has a 

 row of longish, erect, forward-curved hairs and a spiracular pair of small spiny 

 tubercles above the base of the legs which (the tubercles) are about 1 mm. in 

 length. Segments 3 and 4 have got these tubercles at bases of the legs also ; 

 segments 5 an 1 6 hive got them in the place where the legs ought to be but 

 here tbey are both at the same height instead of one below the other as in 

 segments *-4 ; segments 7-1(1 have them like these latter, segment 11 like the 

 former. Segments 5-1 1 have a dorsal, subdorsal, lateral and spiracular spine- 

 bearing pedicel, segments 3 and 4 only a subdorsal and lateral one. segment 12 

 has two dorsal ones, one near front margin, one near hinder maigin (all the 

 other segments having them in the centre) besides the subdorsal, lateial and 

 spiracular oaes; the 13th segment is plainly visible and has the subdorgal pedicels 

 only ; the anal segment only the lateial pedicel near the hindei edge. All 

 the pedicels are swollen at base, of equal length except the ones at the bases 

 of legs which are smaller; the spines are hair-like and disposed iiiegularly 

 along the pedicels and each pedicel ends in a fine, conical hair-like 8{)ine with 

 thickened base. Spiracles are rather small, shiny black, oval, raised. Surface 

 of body covered with minute, conical, white tubercles giving it a velvety 

 appearance. The colour is black and, when full grown, it is lateially reddish 

 brown with an indistinct lightish spiracular line ; dorsally, when full-giown, 

 also, it has a reddish brown tinge with a yellowish shade because of the 

 tubercles between the subdorsal pedicels of each segment ; belly same colour 

 as back ; pedicels dirty watery yellowish, colour of spines brown. L: Sh mm.; 

 B: 7 mm ; L. of pedicels : 2 mm. 



Pupa. — The pupa is of very ordinary nymphaline shape with slight conical 

 proiubeiance in front of each eye, the surface with a few small conical tubercles 

 the colour dirty grey-brown in ^hades. The head is square in licnt and 

 bluuG dorso-ventrally, each eye having a small conical tubercle in front of it 

 pointing straiglit out in front ; the lateral outline ot pupa slopes slightly out- 

 wards from head to shoulders, then hardly at all as far as 8> gment 7-8 

 after which the abdomen narrows to cremaster. The dorsal slope of segment 

 2 and thorax is the same and is about 45° to longitudinal axis ot pupa ;
