Carpenter — The Apterygotu of the Seychelles. 23 



the two ends of which project the short, unjoiiited, bristly goiiapophyses (go.). 

 The cresceutic opening of the ejaculatory duet is just hidden by the above- 

 mentioned ridge when the organs are seen ventrally. In fig. 132 is shown 

 the shape of the opening, as seen through the thin, transhicent cuticle of the 

 genital plate viewed from the dorsal aspect. 



The genital plate in the female (fig. 130) has the same form as in the 

 male, but its ventral surface is feebly granulated, bears no spines, and carries 

 only a few long bristles. The vulvar opening is between this plate and a 

 transverse ridge which projects dorsal to it; between the two lobes (fig. 130^) 

 which bound this flap the central spermathecal opening (fig. 130 .spc) 

 appears, while e.xternal to the lobes are the gonapophyses (fig. 130 go.), less 

 prominent than those of the male. The lobes and the gonapophyses are 

 evidently the inner and outer " papillae " as figured by Grassi ; their 

 arrangement in Heteroiapyx novae-zeelandiae, as sketched by Yerhoeff ('03, 

 pi. xviii, fig. Ha), is very similar. At the extreme tip of the female gonapo- 

 physis is a bluntly conical papilla, around the apex of which five or six 

 minute bristles form a ring (fig. 131). 



Family CAMPODEIDAE. 



The interesting little insects comprised in this family agree with the 

 lapygidae in their retracted jaws, but differ in the nature of the hindmost 

 abdominal appendages, which are elongate tail-feelers or cerei, as in 

 Thysanura generally. Yery little is as yet known of tropical Campodeidae ; 

 being blind insects living in soil and such concealed surroundings, they are 

 seldom collected, and, being very fragile, imperfect and unrecognizable 

 specimens are commoner than those fit for description. The Campodeidae 

 from the Seychelles are few in number but highly interesting, as the species 

 represented clearly belongs to the little -known genus Lepidocampa 

 (Oudemans, 1890), whose members are distinguished from all other 

 Campodeidae by being partially clothed with scales. 



Lepidocampa Oudemans. 



This genus was established by Oudemans ('90, pp. 76-7) for an Indo- 

 Malayan species L. Weheri, inhabiting Sumatra, Java, and Flores. Silvestri 

 ('99) found what he regarded as this identical species in Argentina, and 

 afterwards ('01, p. 242 ; '05, p. 777) mentioned its presence in other parts of 

 South America — Brazil, Paraguay, and Ecuador. Oudemans gives the 

 number of antennal segments (over thirty), as he observed it in the Malayan 

 insects, as a generic character, but Silvestri states that in the Argentine 

 specimens the number of segments in the feelers varies from 22 to 32.
