“…The larger water beetles such as Dytiscus (Hughes 1958), Hydrophilus (Hughes 1958) and Acilius (Nachtigall 1960(Nachtigall , 1974 and the aquatic bugs, e.g. Corixa (Schenke 1963(Schenke , 1965a, Notonecta (Schenke 1965d) and Lethocerus (Lauck 1959), use flattened podomeres with collapsible hairs as oar blades. The whirligig beetle, Gyrinus (Nachtigall 1962), has greatly flattened podomeres and a fringe of collapsible blades, whilst in portunid crabs (Kiihl 1933;Lochhead 1961;Hartnoll 1971;Spirito 1972) the propodus and dactyl of the swimming leg are flattened and bear only fringes of short hairs (Fig.…”

The prosomal morphology of Baltoeurypterus tetragonophthalmus (Fischer) from the Baltic Silurian is redescribed and reconstructed. The first eurypterid labrum and new secondary sexual characters of Baltoeurypterus are described. The radially-arranged coxae of Baltoeurypterus were capable of adduction and abduction for food mastication, but not promotor-remotor movements for locomotion. Joint diagrams are presented for the first time for an extinct arthropod. Promotion and remotion of the limbs occurred about subvertical trochanteral pivots, as in all other chelicerates except xiphosurans. Baltoeurypterus probably walked in a “slow” gait; a method of choosing possible gaits for extinct arthropods is outlined. Swimming in Baltoeurypterus was effected by means of a rowing action of the posterior limb pair, which is provided with complex joints for collapsing the paddle during the recovery stroke. The limb arrangement and joint mechanisms of Baltoeurypterus are intermediate between those of the xiphosurans and the arachnids. It is possible that a sister relationship exists between the eurypterids and some arachnid groups, which would render Merostomata and Arachnida unnatural assemblages.

“…More recently, Cullen (1971) and Govind & Dandy (1970) have adopted a more functional approach. Govind & Dandy applied neurophysiology to their study of the flight musculature of Oncopeltus, a technique used by Barber & Pringle (1966), Dingle (1961) and Lauck (1959) in their respective studies on giant water bugs (Belostomatidae) but otherwise sadly neglected. However, the mixture of disciplines involved in such studies often means that one particular area is favoured at the expense of others and there are many papers where this is evident.…”

The comparative morphology of the wings and axillae of selected Heteroptera

With 4 plates and 16 figures in the text)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 mechaqism for wing folding is described and previously unrecorded adaptations for this purpose seen in Noronecta are described and discussed.

“…However this may not be stated with certainty till further confirmatory work is done as in two separate studies of belostomatid bugs (Heteroptera) this muscle has been assigned different functions. Lauck (1959) states that the dorsal oblique muscle acts as a wing depressor and Barber and Pringle (1966) find that the only clear effect of applying pressure on the insertion of this muscle is supination of the wings. Thus the action of this muscle in Oncopeltus and other heteropterans possessing it remains unresolved.…”

“…Similar studies on the remaining order possessing fibrillar flight muscles, viz. the Hemiptera (subdivided into Homoptera and Heteroptera) are few and incomplete (Lauck 1959;Dingle 1961;McCann and Boettiger 1961; Barber and Pringle 1966;Govind and Burton 1970). T o bridge this gap the present study on the thoracic mechanism of the milkweed bug, Oncopeltus fasciatus (Dallas), was done.…”

“…These publications together with the textbooks of Snodgrass (1935) and Weber (1930) served as the main reference works. Other publications which proved helpful were those of Malouf (1932) on Nezara, Akbar (1957) on Leptocorisa, Rawat (1939) on Naucoris, and Lauck (1959) on Lethocenls. Although the milkweed bug is used extensively in physiological studies, there is no published account of its thoracic mechanism.…”

An illustrated account of the thoracic mechanism of the milkweed bug, Oncopeltus fasciatus (Dallas), is given. The thoracic skeleton including legs and wings is described and this is followed by a discussion of the interaction of these parts with the musculature. The action of the extrinsic and intrinsic leg muscles, being well known, is tabled as are also the origins and insertions of all the thoracic muscles.
