THE SUBFAMILY LIBELLFLIX^. 327 



again connected with another blotch covering the upper part of the triangle and part of 

 the upper cells of the inner triangle, and throwing off another branch towards the base 

 nearly to the cross nervule of the lower basal cell ; on the hind wings the apical patch 

 and the middle band differ only in being more extended ; the basal markings extend 

 to the level of the nodus, and consist of a bar filling the lower antenodal costal space 

 and the lower part of the first, a broader one extending from the membranule (which 

 is white, with a black line in the centre) which narrows outwards, but covers the lower 

 basal cell and the triangle, and then fills up the space between the sectors of the 

 arculus, and fills up the space to the vein of the nodus ; and from the outer side of 

 these confluent basal stripes a band descends nearly to the hind margin, and then turns 

 inwards, again expanding towards the inner margin, but touching neither margin ; the 

 enclosed space is of a slightly yellowish hyaline. Appendages nearly as in C. elisa. 

 Hag., to which this species is allied, but the anal appendages are longer and black, and 

 the upper ones form a more distinct angle beneath before the extremity. 



Immature male. — Head yellow, violet above, the mandibles and the suture of the 

 labium reddish. Thorax reddish brown above, with a yellow stripe on each side ; 

 the sides yellow, with two oblique brown stripes connected above. Abdomen black, 

 shading into reddish brown at the base, with longitudinal yellow dorsal spots on 

 segments 3-7, and with three yellow spots on the side of the first segment, followed 

 by a series of four on the sides of segments 2-4, ending in two small dots at the base 

 of the fifth. Wings paler, the dark markings less extended, and more interrupted by 

 transparent spaces ; the band on the hind wings is broadly interrupted opposite to the 

 hind margin, so that the large spot near the inner margin is entirely disconnected ; all 

 the secondary nervures on and between the dark basal markings of the hind wing are 

 distinctly yellow, which is much less conspicuous in the mature specimen.

Sympetkum pallidinervis. (Neuration, Plate LV. fig. 4.) 

 Long. Corp. 35-37 millim. ; exp. al. 63-G7 millim. ; long. pter. 2^3 millim. 

 Head yellow, vertex violet in the male ; mandibles and suture of the labium black ; 

 occipital triangle brown in the female, the vertex is concolorous, except that the frontal 

 suture is black or bronze ; male with the prothorax yellow above, with a central dark 

 stripe bisected with yellow ; a slender reddish-brown stripe on the pleura before the 

 wings, and three large black sutural stripes on the pleura. Metathorax tessellated 

 with yellow and reddish brown. Abdomen black, the first three segments yellow on 

 the sides, the second with an oval yellow spot on each side above, behind the carina, 

 and the remainder with a long yellow spot on each segment, visible from above, as far 

 as the eighth, tenth segment sometimes partly yellow ; anal appendages a little shorter 

 than the ninth and tenth segments together, pale yellow, tipped with black. Fore 

 wings with 9 antenodal and 8 postnodal nervures, the last antenodal and the first three
