INDIAN DRAGONFLIES. 



oil 



subdorsally which meet over the dorsum on the 9th segment. The 10th 

 yellow, with two small, subdorsal spots, black. 



Anal appendages pale yellow. 



Wings hyaline, the basal half from just distal to the node, a pale amber yellow ; 

 this area bordered outwardly by a broad, ragged, smoky brown fascia extending 

 from the costa nearly to the termen and curving inwards towards the base near 

 the termen, in the hindM'ing. The apices of all wings broadly smoky brown, 

 as far inwards as inner end of stigma. The inferior, costal space blackish- 

 brown. 



Sexual organs not differing markedly from the genus. 



Hab. India, Burma and Ceylon in the moist areas. I have taken this 

 insect in Calcutta, Madras, Bombay, Elephanta Island, Nilgiris, Colombo and 

 Bangalore. In the latter district, it is exceedingly local but where found, veiy 

 plentiful. It favours swampy areas such as new paddy fields or low, moist 

 jungles and may on occasions be seen flitting in countless swarms, its flight 

 reminding one strongly of an Hesperid. Variation is not a noticeable char- 

 acteristic. 



42. Neurothemis tullia feralis. 



Male : very similar to tullia tullia, but the white opal band across wings is 

 absent in the male. The base of wing is black as far as 2 cells proximal of the 

 node in the forewing and to the node in hindwiiig. 



Female similar to tullia tullia. A bright yellow at base of wmgs and a dark 

 apex, the dark ray in the subcostal space and the postnodal dark band absent 



Hab. I include this as doubtful from Burma. Malacca, Java, Siam. 



43. Neurothemis intermedia intermedia, Ris. 



Libellula intermedia, Rambur. 

 Trithemis intermedia, Brauer. 

 Neurothemis intermedia, Selys.
