The female can protrude a long flexible tube in connexion with the eighth segment, carrying the sclerites of the ninth at its extremity, and these sclerites may carry short hairy processes A B D.yrnt,sc/'rle moathd ..
The regions of this cuticle have a markedly segmental arrangement, and the definite hardened pieces (sclerites) of the exoskeleton are in close contact with one another along linear sutures, or are united by regions of the cuticle which are less chitinous and more membranous, so as to permit freedom of movement.
I, 2) is composed of a number of sclerites firmly sutured together, so that the primitive segmentation is masked.
- Legs and Ventral Thoracic Sclerites of Female Cockroach (Blatta).
Ventral cervical sclerites III, Hind leg and metasternum.
Its attachment to the trunk, we find a highly complex series of small sclerites adapted for the varied movements necessary for flight.
In the abdominal exoskeleton the segmental structure is very clearly marked, a series of sclerites - dorsal terga and abdominal sterna - being connected by pale, feebly chitinized cuticle, so that considerable freedom of movement between the segments is possible.
The sclerites of the eighth and ninth being frequently hidden by those of the seventh.
Ing the dorsal with the ventral sclerites of the Lateral thoracic abdomen, lessens t he capacity of the abdo ternal femoral minal region, while the contraction of the power Longit.
The " sclerites " that make up the skeleton of the insect (which skeleton, it should be remembered, is entirely external) are composed of this chitinous excretion.
There is also a pair of narrow tergal sclerites interposed between the anterior and posterior shields.
- Integument soft, strengthened by special sclerites, those on the ventral surface of the prosoma apparently representing the basal segments of the legs embedded in the skin.
A, Lateral view with appendages III to VI removed; 1, plate covering the whole dorsal area, representing the fused tergal sclerites of the prosoma and opisthosoma; 2, similarly-formed ventral plate; 3, tracheal stigma.
Sclerites and the softness of the skin, but with the respiratory system absent.
A, malleate, with crop: this is followed enlarged view of malleus above - the by the crop-gizzard, Y-shaped incus consists of a short median also ciliated except fulcrum bearing two large rami, each of behind, where it is which is in contact with a stout malleus hardened into a set consisting of a toothed uncus carried on a of articulated sclerites long manubrium; b, sub-malleate, with (trophi) to form the enlarged view of malleus - the manubria gizzard or mastax.
