1922.] F. C. Fra.ser : Odonata from the Nilgiris. 9 



that it is phosphorescent and in fact it appears to glow like the 

 lamp of a glowworm. 



The second line on the thorax is ochreous in colour, and the 

 first 6 segments of the abdomen are blood-red. 



Female. Measurements of the two specimens : — 



Abdomen 34 mm. Forewing 35 mm. Hindwing 32 mm. 

 ,, 34-5111111. ,, 36 mm. „ 34 mm. 



The wings are slightly entumed throughout and the apices of 

 both are tipped with brown, especially the hindwing where this 

 colour extends in as far as the proximal end of the stigma. For 

 the rest, the female does not differ from typical P. fraseri except 

 that the antehumeral lines do not meet anteriorly on the thorax, 

 but are parallel throughout. 



Habits. This insect is found perched on plants and twigs 

 overhanging the borders of the streams it . frequents. Unlike 

 most if not all other Calopterygines it is frequently seen settled 

 with the wings outspread and the abdomen raised at an angle 

 like many Labellulines. 



The females are rarely found near water, but penetrate into 

 the neighbouring jungle where they may be found paired with 

 the males. 



Type male and female in my own collection, paratypes in 

 British and Indian Museums. 



The distribution of this insect and P. dispar is extraordinarily 

 local. The two never apparently occur together, but may be 

 found on the same stream at different altitudes. At Gudalur 

 P. dispar is found at an elevation of 4000 to 4500 ft., often in 

 considerable numbers, whilst two miles further down the valley 

 at an elevation of 3500 ft., P. fraseri is quite common. On the 

 opposite side of the Nilgiris P. dispar is met with at elevations 

 varying from 3500 to 6000 ft. at Coonoor, P. fraseri being entirely 

 absent. 



Phyllomacromia nilgiricnsis Fraser. 



Female. A single female, 24 , vii"i92i, near Kalar. 



The type is in the British Museum and was taken in June, 

 1917, by myself at a stream not far above Kalar. I have now 

 secured another specimen, also a female, taken on the same stream 

 at about 100 yards from where the type was caught. 



The wings of this specimen are enfumed throughout, the 

 colouration forming a diffuse network corresponding to the nervui es. 

 The saffronation extends out nearly to the trigones ; otherwise it 

 does not differ from the type. 



Taken whilst ovipositing in wet sand which formed the floor 

 of a small, dark cavern amongst rocks bordering a mountain 

 stream.
