As special facilities existed for doing so, the mouth-parts 

 were examined and compared with the maxilla, hypopharynx, 

 and labium as figured by Hagen for Z '. campanulata (Monogr. 

 Gomph. pi. xiii. fig. 1, p, q, r). The maxilla is much alike 

 in the two species, and so is the hypopharynx, except that in 

 the genotype it is more deeply excavated anteriorly. As to 

 the labium, the end-hook of the lateral lobes is in the new 

 species longer than the movable hook, whereas in Z. cam- 

 panulata it is shorter than the movable hook, [u addition to 

 the maxilla, drawings have been made of the mandible in 

 Z. bodkini, and I am not aware that this organ has ever been 

 figured for any nearly related species. 



The vulvar lamina in Z. campanulata has also been figured 

 by Hagen (loc. cit. fig. 1, t), and is not so deeply bifid at the 

 apex as in Z. bodkini. 



The species is dedicated to Mr. G. E. Bodkin, the Govern- 

 ment Economic Biologist, British Guiana, and the holotype 

 has been presented by him to the British Museum, through 

 the Imperial Bureau of Entomology.

 No. 64 (British Museum). 



Length of abdomen 41 mm. ; length of hind wing 34*5 mm. 



Head moderately large. Labium greenish yellow ; the 

 superior margin of the middle lobe and the internal anterior 

 angle of each lateral lobe black. Base of the mandibles 

 greenish yellow. Labium greenish yellow, bordered all 

 round with black. Clypeus and frons greenish yellow ; the 

 free inferior margins of the postclypeus black. Superior 

 surface of frons with a deep median groove, filled in with 

 black in its posterior two-thirds ; abroad black band crossing 

 the frons transversely in its posterior third. Upper surface 

 of head before the occiput black, except for a pale brownish 

 spot behind the median ocellus. Occiput pale brownish. 



[Piothorax lost.] 



Meso-metathorax chocolate-brown, with five yellow or 

 greenish-yellow stripes on each side of the mid-dorsal crest, 

 increasing progressively in width from above downwards — 

 the first, lying on the dorsum, curved, diverging anteriorly 

 from its fellow, and not quite reaching the mesothoracic half- 

 collar above ; the second running parallel with and lying a 

 little above the humeral suture ; the third crossing the 

 mesepimeron medially ; the fourth occupying the posterior 

 half of the metepisternum, and at about mid-height throwing
