INDIAN DBAGONFLIES. 683 



Wings hyaline or slightly washed with dirty yellow especially in the female 

 reticulation black ; costa yellow along its anterior border ; stigma short, black 

 (2 J mm.), covers about li cells ; membrane grey ; in the forewing 13 to 14 ante- 

 nodal nervures, 6 jDOstnodals and 2 rows of discoidal cells. In the teneral female 

 the wings are faintly saffronated in their basal half and along the costal border, 

 the extreme base is deeply saffronated as far as the 1st antenodal nervure ; the 

 stigma is brown and the membrane white. 



In some specimens of males, the wings are a bright saffron for about three- 

 fourths of their extent but whether this is a teneral condition or not is 

 doubtful. 



(In one specimen which I have before me, the apices of the forewings are 

 bright saffron as far as the node and for the whole length of the subcostal space. 

 In the hind-n-ings, the saffronation is a little deeper and extends as far as 2 post- 

 nodals from the node but the margin extends obliquely to the termen, which it 

 reaches at the 8th (Cui) nervure. The extreme base is also deeply saffronated in 

 the subcostal and cubital spaces. This specimen was undoubtedly a teneral one.) 



General colour, deep glossy black, variegated \vith yellow. 



Head : labium and labrum yellow, the middle and lateral lobes of former and 

 the edge of labrum bordered with black ; face and frons yellow, the front of latter 

 black, which colour is connected with a black spot lying in the suture above the 

 front so as to form a large T-shaped mark. Vertex, occiput and back of eyes 

 black, the latter a beautiful emerald green. 



Thorax metallic blue marked with yellow as follows : — the antealar sinus, an 

 antehumeral band not extending as far up as the sinus and laterally, a broad, 

 median stripe which ascends between the bases of the wings to traverse the 

 tergum and connect up with its fellow from the other side. 



Abdomen black, ringed with bright, sharply defined yellow rings. On the 

 2nd segment, the ring very broad and occupying nearly the basal half, on the 

 3rd a semi-annule above and a broadish spot laterally, on the 4th to 6th the rings 

 occupy one-fourth of the segments, being complete and nearer the base than the 

 middle of each segment, finally on 7 and 8 the rings occupy the basal half. 



In the male the abdomen is cylindrical, a little tumid at the base and somewha- 

 dilated from 7 to 9 : on the dorsum of the 10th segment is situated a median, 

 short, pointed, stout spine, which appears right-angled in profile. 



In the female the abdomen is stouter, not dilated at the end and markedly 

 compressed laterally. 



Legs slender, bro-miish black or black, the anterior pair yellow on the basal 

 half of their flexor surface. 



Anal appendages of male black, the superior longer than the 10th abdominal 

 segment, a little subcylindrical, the inner border straight, the outer furnished 

 at its middle with a robust spine. The terminal half tapered and ending acutely. 



The inferior appendages of equal length, triangular, a little curved up and 

 blunted at the end. In the female, the appendages are rather longer than the 

 1 0th segment, conical, pointed and black. The vulvar scale slightly cleft. 



Hob. Bengal, the Deccan. Moderately common at Poona. A male taken 

 at Mahableshwar near Bombay. In Poona it is met A\ith, either follomng the 

 course of shallow swift streams, hovering closely over the surface of the water, 

 or else hawking up and down lanes or openings in the jungle and very occasion 

 ally setthng low down on twigs. 



Closely alhed to cincta but smaller, the markings much brighter and better 

 defined and labrum bordered with black.
