Abstract: | The wings of selected species are here treated as functional deformable aerofoils and their morphology described with this in mind. A novel type of non-tubular vein structure in the forewing and hindwing membranes, a 'channel vein', is described. The presence of small, cuticular membrane thickenings in the hindwing is recorded and their possible functions are discussed. A comparative account of the structure and musculature of the axillae is presented with a view in particular to clarifying some of the associated terminology. A mechanism for wing folding is described and previously unrecorded adaptations for this purpose seen in Notonecta are described and discussed. |
