wing and to the second antenodal in tiie hind wing, instead 

 of ceasing Imlfway to (fore wing) or at (hind wing) the 

 first antenodal ; and (4) the pterostigma abont 1 mm.sliorter 

 and of a darker and redder shade of brovvn. The hanmles 

 of the two forms are barely distinguishable from one 

 another. 



Specimens of Indothemis are still very rare in collections, 

 and the female of /. limbata limbata has never been 

 described. Although the female of /. ccesia, Ramb., was in 

 the possession of De Selys-Longchamps in 1884^ he mistook 

 it for Si/mpetrum meridionale, and the unique specimen 

 remained unrecognised for more thanaqnarter of a century. 

 The undescribed female from Ceylon likewise resembles a 

 Sympetru7n^ and at a cursory glance might easily be con- 

 fused with S. dance, Sulz., $ .

^ (holotype). Trincomali, 6. xii. 1890, Yerbury. 



Closely resembling the ^ of /. limbata limbata, Selys. 



Length of abdomen 23 mm. ; hind wing 27 mm. 



Wings hyaline, except at base. Fore wing with umber- 

 brown streaks in the (1) subcostal space, ending at the 

 first antenodal, (2) cubito-anal space, ending at the anal 

 crossing, and (3) basal cell in the anal field. Hind wing 

 with large umber-brown basal spot_, extending outwards to 

 a point between the first and second antenodals, and con- 

 tinuing posteriorly at about the same level to the end of the 

 first proximal cell in the anal loop : the outline then pro- 

 ceeds obliquely to meet the inner margin of the wing at a 

 point four or five cells beyond the apex of the membranule. 

 Pterostigma 3mm. long, dark reddish brown. Antenodals

with one row of three cells next to the triangle. Triangle 

 of right fore wing free. 



On the dorsum of segments 7 and 8 of the abdomen a 

 pair of conspicuous orange-brown streaks, somewhat less 

 than half the length of the segment. On the ventral surface 

 of segments 5-8 (and perhaps on 4 also) a pair of stripes 

 similar in position, length, and colour to the streaks on the 

 dorsum of 7 and 8, but wider.
