INDIA. 327 sno^e7^bnIeadyuT\theUppe^partSreenei-; °cciput obscurely spotted thorax reddish brown, w.th two yellow lateral stripes edged externa ly with black, and two yellow pleural stripes edged in front by the black sutural lines; legs varied with black, yellow, and reddish; between the wingsi runs a row of yellow markings simihr to hose found m many female Libellulince; abdomen dull reddish tawny, with black lateral carinas and a black dorsal stripe, commencing on the second segment and narrowed at all the sutures. Wings nearly as in the male ; one specimen has thirteen antecubital nervures. Campbellpore, Nov. 14 (d1 $ ) ; Murree ( $ ) , no date; upper slope or Nian Jam, above Kalabagh, about 9000 ft., Sept. 16 (9) Allied to the European O. ccerulescens, Fabr., and O. ramburii, He Selys. ' 7. ORTHETRUM TRIANGULARE, De Selys (nos. 3 and 4). Murree, Aug. 10 and 16 ( J ) , Aug. 16 and 18(?) the male much resembles the inky-black O. carnaticum, Fabr, which we have from Nepal. The females differ considerably in the intensity of colouring of the thorax and abdomen. As in some allied species, the particoloured eyes are remarkable in both sexes the upper portion being reddish and the lower parts dark brown. ' 8. ORTHETRUM NEGLECTUM, Ramb. (no. 3). Hassan Abdal and Campbellpore, Oct. 14 (d $ ) and Nov. 14 The female is very similar to that of O. triangulare, but it lighter in colour; the wings are clear hyaline (rarely the case in £. triangulare) ; and the pleura) are uniform yellowish, with a small black ocellus on the mesopleura. 9. TRITHEMIS AURORA, Burm. (Plate XXXIII. fig. 3.) A somewhat undercoloured male, without date or locality The species, which I take to be T. aurora, has only 10-11 ante cubital and 6-8 postcubital nervures on the fore wings, placed rather widely apart. Like the next species it occurs both in India and Oey on, but seems to be rarer. We have no specimens from the -Philippines, the locality given by Burmeister. 10. TRITHEMIS INTERMEDIA, Ramb. (no. 13). (Plate XXXIII fig. 4.) Hassan Abdal, Oct. 14 ( J1). May be distinguished from T. aurora by the more numerous and crowded nervures-14-15 antecubital and 8-9 postcubital- the markings of the thorax beneath uesemble those of T. rubrinervis De Selys. ' 11. TRITHEMIS FESTIVA, Ramb. (no. 12). Hassan Abdal, Oct. 14 (tf ); Campbellpore, Nov. 14 (c?). |
