The curving ridge just above the lower carina is the lower carnula.
The upper and lower carnulae are separated by an area which shows a herring bone pattern of faint groves or chevrons. On the inner face of the hind femur there is usually a straight inner carnula which in the slant-faced grasshoppers, runs below a row of minute stridulatory pegs.
Orthoptera usually have two pairs of wings ; the narrow forewings covering the fan-like hindwings. The forewings are often leathery and so are known as tegmina. When the wings are spread, the leading edge of the forewing is the costal margin and the trailing edge is the inner margin. Often the wing area immediately behind the costal margin costal area is enlarged and is crossed by a series of parallel veins which run obliquely slant-wise to the margin. This gives the area the appearance of a series of windows or fenestrae.
In many grasshoppers, a raised longitudinal vein can be seen posteriad of the costal area and running parallel to the costal margin. This is the intercalary vein. Bandwing grasshoppers produce sound by rubbing the hind femur across this vein.
The abdomen is essentially cylindrical with a series of dorsally over-lapping plates or tergites and a similar series of ventral plates or sternites.
In the suborder Caelifera, a large blister-like structure or tympanum can be seen near the base of the abdomen. Posteriad, the abdomen has the specialized reproductive structures which are somewhat different for each suborder.
In Caelifera, males have a triangular shield-like supra-anal plate occupying the dorsal surface posteriad. From the tergite at its base there are often two finger-like projections termed furculae.
Laterally and projecting posterio-dorsad on each side is a cercus which is usually flattened but may be tapered from base to apex. Ventrally, the last segment is the subanal plate. This plate or sclerite is usually evenly rounded but may taper to a rounded or bilobed apex. The lateral edges of this plate may be straight or arched. In females, the abdomen terminates in a point which is in fact four closely appressed points.
These are the ends of the paired dorsal and ventral valvulae which together make up the ovipositor. Hidden internally is an additional pair of valvulae which act as egg guides. In side view, the profile of the dorsal valvulae appears as a straight or weakly arched edge followed by the posterior scoop. What is the tympanum? Is Mike Tyson any relation to Cicely Tyson?
