several sections, which arrangement will, I hope, facilitate to some 

 extent their identification. In this grouping I do not follow exactly 

 de Selys' classification given in the monograph. Having to deal 

 only with oriental forms I have adopted an order which bears more 

 directly on them. 



As usually is the case with collections of Goraphines the 

 males are more abundant and more readily recognizable than the 

 females. Hence in this list, as elsewhere in the paper, I am forced 

 to rely largely on male characters, a practice not by any means 

 theoretically ideal but, at the worst, useful in practice. 



Section I, grammicus. 



Frons and front of head entirely yellow. Dorsal stripes of syn- 

 thorax not meeting mesothoracic collar, antehumeral stripes com- 

 plete. Apex of abdomen of male not dilated. Upper anal ap- 

 pendages about twice as long as branches of lower appendage. A 

 ' xerophilous ' section. 



Onychogomphus grammicus Selys. 



id. Agra. S. Hankin. 



Front of head including the whole of the frons, entirely 

 yellow. Vertex and occiput largely yellow. Synthorax with 

 dorsal yellow stripes not meeting the mesothoracic collar, ante- 

 humeral stripes complete. Femora and tibiae largely marked with 

 yellow. 



Abdomen almost cylindrical ; the eighth segment shows a 

 slight increase in depth compared with the others. The first seg- 

 ment is almost entirely yellow. The second has a trilobed longi- 

 tudinal dorsal mark of yellow enclosed between lateral bands of 

 brownish-black. Segments 3-6 are whitish-yellow as far as the 

 transverse carina and beyond this black, but the black is marked 

 with a prominent yellow spot dorsalty, lying longitudinally. 



Segments 7-10 entirely sandy yellow. Anal appendages of the 

 same colour, upper pair nearly twice as long as branches of lower 

 appendage; very like those of 0. lineatus, but flattened and 

 truncate apically. 



Length of abdomen 325 + 3 mm., of hinder- wing 29 mm. 



Closely allied to 0. flexuosus Schneider, Asia Minor. 



Section II, lineatus. 



Front of head and frons entirely yellow save for a small 

 transverse black line on the crest of the frons. Dorsal stripes of 

 synthorax not meeting mesothoracic collar, antehumeral stripes 

 complete. Apex of abdomen of male but little dilated from side 

 to side, segments 8 and 9 carry leaf-like expansions. Upper anal 

 appendages closely apposed, parallel and strongly decurved apically, 

 lower appendage about one-quarter of the length of upper pair. 



To this group belong the species 0. genei Selys, and 0. ftumilis 

 (Ramb.) Further the two species of Mesogomphus that I have seen
