No. XXXVIII.— THE UNDESCRIBED FEMALE OF AN INDIAN 

 DRAGONFLY, HEMICORDULIA ASIATIC A. 



Whilst looking over a small collection of dragonfiies sent to me from 

 Pusa by Mr. Bainbrigge Fletcher, I was pleased to find a pair of the very 

 rare dragonfly, Hemicordidia asiatica, Seiys, the female of which has 

 hitherto been unknown. Only two specimens of this insect are known, both 

 males, one in the Selys collection, which has been probably looted or 

 destroyed by the Germans and another which was taken by Mr. Stevens 

 in the Abor Expedition. The former specimen was taken in the Khasi 

 Hills, the latter at N. Lakhimpur, Upper Assam, whilst the Pnsa pair were 

 taken in Shillong. 



The (5 and $ are much alike, difl'ering only in the shape of the wings 

 and abdomen ; the following is a description of the $ . Head ; eyes green ; 

 vesicle, frons and upper epistome metallic green, lower part of epistome, 

 the labrum and labium bright yellow. 



Prothorax brown with a large, dorsal, yellow spot. 



Thorax metallic green, with two broad, bright yellow stripes on the 

 sides, one post-humeral and the posterior one involving the whole of the 

 metepimeron. Legs black marked with yellow. 



Wings clear hyaline, thus difl'ering from those of the male which are a 

 little smoky. The anal angle (tornus) rounded. Hind 35 mm. 



Abdomen. Segments 1 and 2 dorso-ventrally dilated, segments 1 to o 

 compressed laterally, the remainder strongly depressed, 7 to 9 moderately 

 dilated. Length 32 mm. Colour black marked with yellow along the 

 sides, the first 3 segments by a continuous fascia, 4 to 8 with elongated 

 spots which reach the base of each segment. The dorsum of the first 2 or 

 3 segments metallic green. 



Genital organs. Distal border of the 8th ventral plate prolonged as two 

 small foliate processes, the 9th with a poorly developed vulvar scale, not 

 overlapping the 10th.

No. XXXIK.—LIJiELLULINES AT ST. THOMAS' MOUNT, 



MADRAS. 



The following notes were made as the result of several excursions, during 

 the months of February and March, of this year, in the neighbourhood of 

 St. Thomas' Mount, Madras. No notes, so far as 1 am aware, have hitherto 

 been published of the species of the Odonatn occurring in this locality. 

 These notes deal only with the LihelliiHne.'<, but I hope to publish a list of 

 some of the other families found in this neighbourhood. The nomenclature 

 is that used by Major F. 0. Eraser, i.M.s., in his articles on Indian Dragon- 

 flies now appearing in the journal. 



Tanks and wells were full in February around the Mount, and the 

 weather was cool and pleasant. Towards the end of March however the 

 weather began to grow unpleasantly hot, and the water-level in the tanks 

 liad fallen about six to eight feet. The change seemed to make no 

 difi^erence in the number of dragonfiies about. Dragonflies were numerous 

 throughout the months of B'ebruary and March, but the number of species 

 was not large. Larvte appeared to be maturing constantly as juvenile 

 forms, of almost all the species taken, were found throughout the period.
