286 Mr. Kenneth J. Morton on 



sent me a few dragon-flies. In this example, on 1st seg- 

 ment of abdomen there is a broad obhque lateral band not 

 reaching quite to the ventral suture. The yellow dorsal 

 band of 2nd segment is not broad but is continuous with 

 the anterior lateral yellow marking; the black dorsal 

 marking of this segment with a prominent middle lobe ; 

 hind lunules well marked, broadly disconnected with the 

 lower lateral posterior marking, which is small; lateral 

 marking on segment 9 basal only ; none on segment 10. 

 Antenodals : forewing 14; hind wing 11. 



II. Race amasinus, nov. 



From Amasia there is a series of 4 males in which the 

 yellow dorsal markings are much more highly developed, 

 being present even on 1st segment in a limited degree. In 

 this segment the lateral markings are variable, in one case 

 at least nearly reaching the ventral suture. Lunules on 

 segments 2, 3 and 4 sometimes not interrupted by the dorsal 

 arete, and may be represented on all the other segments to 

 the 8th or 9th; 9th and 10th showing both anterior and 

 posterior lateral markings. The nasus is entirely yellow. 



In two females presumably from the same locality, there 

 is a trace of the anterior line on the frons, but the virgule 

 on the labrum, though distinctly present, is entirely uni- 

 colorous with the disc. The nasus is very slightly marked 

 with brownish on the anterior margin. 



Antenodals: (^, forewing 16-17; hind wing 11-12; $, 

 forewing 15-16; hindwing 12. 



De Selys in his notes on C. insignis does not refer to the 

 colours of the prothorax. It should be here noted that in 

 form I the posterior yellow line is broadly interrupted and 

 short ; there is also an interrupted median yellow line, with 

 two yellow dots between it and the posterior margin ; the 

 anterior margin is also yellow. In II (omasinus) the pos- 

 terior yellow line is interrupted but much longer, and the 

 other yellow markings on the prothorax are well defined. 



III. Race nobilis, nov. 



At Van, in the extreme east of Asia Minor, near the 

 Persian frontier, there is a still further increase in the yellow 

 markings at the expense of the black ground-colour, if 

 indeed these examples (2 (^ (^, 2 $ $) belong to C. insignis.
