vesicle metallic green above ; occiput small, brown ; eyes emerald green, black 

 behind. 



Prothorax brown. * 



Thorax rich mahoghany red on lower part of the front, metallic green above 

 and at the sides, no humeral stripe but a moderately broad, oblique, bright 

 canary yellow stripe on the middle of the sides, passing up between the bases of 

 the wings to traverse the tergum and connect up with its fellow from the other 

 side. The antealar sinus and a spot behind it, yellow. 



Wings slightly smoky and palely sufEused with saffron in the basal half, poste- 

 rior to the ti'igone and for the basal half of the hindwings posterior to the 8th 

 nervure (Cui) ; costa black anteriorly, 13 to 14 antenodal nervures, and 11 post- 

 nodals to the forewings. 



Abdomen matt black, marked with yellow as follows : — a dorsal spot on the 

 2nd segment, shaped Uke a mushroom with the stalk directed apically, narrow 

 annules on 3 to 5, a little notched basally with black, a broad, basal annule on 

 segmeiit 7 pointed apically on the dorsal crest, remaining segments unmarked. 



Anal appendages short, black, longer than the 10th segment, the superior with 

 a robust spine on its outer side, situated a little beyond the middle, the apex 

 turning out a little ; the inferior of the same length, slightly notched at the apex. 

 A strong keel on the dorsum of the 10th abdominal segment commencing basally 

 with an angulated eminence, on either side of which is a small, conical tubercle. 

 Seen from behind, these appear as three small tubercles. 

 Legs long, slender, black. 



Female differing but little from the male. The yellow markings on abdomen 

 broader, the abdomen compressed laterally, the anal appendages black, conical, 

 pointed, rather longer' than the 10th abdominal segment ; wings slightly smoky ; 

 vulvar scale cleft. 



Hab. Shillong, Assam. Taken by Mr. T. Bainbrigge Fletcher hawking over 

 pebbly streams. Several males and females were taken or seen from the 5th to 

 the 30th September. Oviposition was accompUshed as in the Libelluhnse, by 

 hovering and dipping the end of abdomen in water. 



Closely alhed to M. moorei from which it may be distinguished by the stigma 

 being black instead of yellow, the appendages of equal length instead of subequal , 

 no yellow markings on the 8th and 9th segments and by the character, of the 

 tubercles on the 10th segment. From horneensis, which it resembles closely in 

 colouring, it may be distinguished by the black costa and by the 10th segment. 

 From flavicincta and cingulata by the non-possession of a humeral stripe. 

 Genus — Phyllomacromia, Selys. 



Wings of PJiyllomacromia nilgiriensis. $ (x 3).
