Carpkntkr — The Apterygota of the Seychelles. l9 



resemble those of Silvestri's species rather closely, even to a characteristic 



difference between the right (fig. 104) and the left jaw (fig. 105) in the form 



and arrangement of the teeth. The lars^e retractor muscle of the mandible 



(fig. 104 re) is broad and strap-shaped ; the fibres of the principal adductor 



(fig. 104 «f^) are gathered into a narrow tendon, whence they radiate to the 



inside of the convex border of the appendage, as in the Lepismatinae. The 



■maxilla resembles that of Nicoletia as figured by Escherich ('04, Plate If, 



fig. 27), but the palp in Lepidospora is relatively much longer. The terminal 



segment of the palp carries at its tip four knob-like sensory prominences 



beset with numerous fine hairs (figs- 107, 110, s.p.) ; it also bears, a little 



behind the tip, a flattened, annular structure (fig. llO.s.i-.), which may also be 



regarded as a sense-organ. At the tip of the remarkably slender galea 



(fig. 107 ga.] are two peg-like spines, probably sensory. The lacinia (fig. 107 L, 



fig. 108) has two teeth at its extremity, and carries on its inner border a most 



beautiful and elaborate "comb-process " (fig. lOSc.^j.). This process is beset 



towards its tip with a double row of strong spines (fig. 109), while at the 



base there is a series of four or five complex, flattened spinose processes, one 



branch of each lieing bifid at the extremity (fig. 108). 



The iongne (fig. 106 hg) is relatively narrower than that of Isolepisma ; 



its tip is emarginate, with a small central prominence. The maxillulae 



(fig. 106 wi-rf.), rather long and narrow in form with rounded extremity, are 



beset with oblique, parallel rows of fine hairs. 



The labium (fig. Ill) resembles rather closely that of Nicoletia as figured 



by Escherich ('04, Plate II, fig. 32), the basal plate, galeae, and laeiniae 



being relatively longer and narrower than the corresponding parts in the 



Lepisminae. In Nicoletia, however, the tip of the lacinia is bifid, while in 



Lepidospora it is simple. The very broad terminal segment of the palp bears 



six circular, cushion-shaped sense-organs, each beset with numerous fine 



hairs (fig. 111). 



A thoracic leg in Lepidospora consists of coxite, trochanter, thigh, shin, 



and three-segmented foot (Plate X, fig. 112). The coxite carries several 



bifid hairs. At the tip of the shin is a strong, claw-like si)ine overhanging the 



base of the foot. At the tip of the foot are two strong claws, beset on the 



basal half with fine short hairs ; between the claws projects a slender 



empodium, bluntly rounded at its extremity (fig. 113). No feature of special 



interest is presented by the sterna of the abdominal segments from the second 



to the seventh. Each carries, as usual in the group, a pair of stylets and a 



pair of protrusible vesicles (fig. 114). 



Turning to the terminal abdominal segments and their reproductive 



processes, we find that those uf the male have been already well figured
