8 Records of the. Indian Museum. [Voi,. XXIV, 



Male. Abdomen 49 mm. Hindwing 22 mm. 



This species is very closely related to P. gravelyi from which 

 it differs by the greater length of the abdomen and by the 8th 

 abdominal segment having its basal third of half pale blue instead 

 of all black as in P. gravelyi. The dorsal carina of this segment 

 is narrowly black in its basal half. 



Female. Abdomen 37 mm. Hindwing 23 mm. 



Differing from P. gravelyi, which it much resembles, by the 

 difference in the relative lengths of hindwing and abdomen and 

 the markings of the abdomen. The basal annule on segment 7 

 occupies about the basal fourth and there is no basal annule to 

 segment 8 but a lateral, irregular spot. There is also a large 

 diffuse white spot on the outer side of the eye which is not present 

 in P. gravelyi. . . ( 



The ovipositor of this and other species has a large, promi- 

 nent, stout, upward-turned spine on its dorsal apical surface. 



Habits. As for the genus, but bolder and to be seen frequently 

 flying in mid-stream. Large numbers of males were seen on the 

 3rd of Julv all with their heads facing up stream and travelling 

 slowly in that direction. A few were seen paired, but the females 

 as a rule kept to the shelter of the scrub lining the stream, where 

 apparently the males sought them. By the 23rd of July the num- 

 bers had greatly diminished and few were seen.

. Thanks to the kindness of Mr. Laidlaw I have been able to 

 compare the above specimens taken by myself with a paratype of 

 P. fraseri and I find that the differences are so marked as to 

 constitute a very distinct race if not a new species. For the 

 present and until I receive Mr. Laidlaw's opinion I propose to 

 call this race wynaadensis. 



The differences are as tabulated : — 



P. fraseri. 



Length of forewing 35 mm. 



Greatest breadth 6-5 mm. 



Apical third of hindwing 

 opaque, from 85 to 10 mm. 

 long. 



Length of abdomen 38 mm. 



P. fraseri, race wynaadensis. 



Length of forewing 38 mm. 



Greatest breadth 7 mm. 



Considerably more than the 

 apical third opaque, from 12 to 

 13 mm. long. 



Length of abdomen 43 mm. 



In addition to the above the anterior pair of femora are 

 brownish black on the flexor surface, bright yellow on the extensor. 

 The dorsal wedge-shaped line is bright turquoise blue and is so sharp- 

 ly contrasted with the black background as to give the impression
