Anal ai^pendages very short and pointed, black. Very similar to those 

 of the Agnonines. Vulvar scale conspicuous, acuminate, ridged and 

 transversely striated in its distal part. 



Habits. — This rare insect, of which I only possess one specimen, 

 belongs to the Phyllomacromia and is the first of its genus to be report- 

 ed from India. Its specific characters are the non-prolongation of 

 the trigone with the arc, the entirety of the trigones, the dilatation of 

 the 8th abdominal segment and the single row of discoidal cells. 



The single female specimen was taken in a marsh at the foot of 

 the Nilgiri Hills above Kalar at 2,000' altitude last June whilst in 

 the act of depositing its eggs in very shallow water. Although I 

 visited the same spot frequently afterwards in the hopes of obtaining 

 more specimens, I never saw another. It has a very feeble flight. 



2. HYL^OTHEMIS FRUHSTORFERl, Kirby. 



(Kirby Catalogue of Neuroptera-Odonata, p. 44, 1890.) 



( Tetrathemis fruhstorferi, Karsch.) 



Ris, 1911, in his work on the Libellulines. states that the female of this 

 insect is unknown and I know of no description published since that date. 



In his description of the male, made from dried and obviously faded 

 specimens, he gives the markings of the insect as j^ellow but in the living 

 state yellow marked males are exceedingly rare. 



Blue marked specimens almost invariably fade to a yellowish tint so that 

 Ris may have fallen into a very natural error when describing the males. 

 The following is a description of both sexes made from living specimens. 



Male: Expanse 60 mm. Length 38 mm. 



Head moderately rounded : eyes very shortly contiguous, bottle-green 

 above, yellowish-green beneath : labium bright yellow, its inner border and 

 the middle lobe, black ; front rounded, without a marked rounded anterior 

 border, it and the vesicle a brilliant metallic green, the latter moderately 

 large and almost imperceptibly notched : epistome and lower part of face, 

 bright yellow : sutures moderately deep : occiput black with a spot of 

 bright yellow posteriorly. 



Frothora c : lobe large, projecting, rounded and notched centrally, fur- 

 nished with a fringe of long hairs along its posterior border. Black with a 

 blue collar anteriorly, an angular spot on the mid-dorsum and the whole of 

 the lobe, pale blue. 



Thorax narrow, deep black with pale blue markings as follows : — Two fine 

 parallel lines in mid-dorsum with a sniall T shaped mark between them : an 

 irregular, sinuous, humeral line and 2 broad lateral fascise. Occasionally 

 the lateral blue markings are a greenish-yellow or become quicklj' so from 

 post-mortem changes. The underside of the thorax and often the sides, 

 over-laid with a white frosting which gives the black ground colour a 

 bluish appearance. 



Le(j8 moderately large and robust, black with white frosting on the under 

 surfaces, giving them a bluish appearance : femora 3 with an external row 

 of numerous, very small, triangular, apicalwards directed spines : a longer 

 spine at the distal end : femora 2 with similar spines on its basal half, then 

 more widely separated, three terminal spines. Tibial spines long and 

 slim : claw-hooks robust, the points not meeting. 



Abdomen slim, base very slightly dilated, 3rd to 6th segments triangular 

 on cross section and very slim, 7th to 9th a little dilated and together 

 forming a fusiform enlargement of the abdomen. Black with blue markings 

 as follows : — a triangular spot on the mid-dorsum of the 1st segment, a 

 linear mark on the mid-dorsum of the 2nd, lateral spots on sides of
