Cakpenteij — The Apterjjgota of the Seychelhs. 6 



manhilis were collected in mountain-forest regions, olTering in this respect a 

 great contrast in habit to most Machilidae, which delight in stony places. 



Three species from the Seychelles are referable to this new genus ; they 

 may be distinguished by obvious characters. 



A. Insects of the usual Machilid build ; paired ocelli transverse. 



a. Legs and claws short, scopulae large and very dense 



(fig. 17). Maxillary palps longer, 



Cordhromachilis Gardineri. 

 h. Legs and claws long, scopulae less dense (Hg. 44). 



Maxillary palps shorter, . . . . C. hrevipalpis. 



B. Metanotum raised into a great dorsal prominence (fig 45). Head 



with conical process between the eyes, paired ocelli shortly 

 ovoid (figs. 46, 47), ....... C ijihha. 



Corethromachilis Gardineri sp. nov. 

 (Plates I, II, figs. 1-26.) 



Paired ocelli (fig. 2 p-o.) of the usual dumb-bell shape, about a transverse 

 diameter apart. Feelers more than twice as long as body (fig. 1); basal 

 segment (fig. 2) three times as long as broad; regions of flagellum (fig. 3) 

 with 16-18 segments each. Mandible (fig. 4), maxillula (fig. 5 Mxl), tongue 

 (fig. 5 7t./y), galea of lacinia (fig. 6/7), and labium (fig. 12) exceptionally broad 

 in proportion to their length. Maxillary palp one-third lengtli of body. Legs 

 short, claws' remarkably short, and scopulae very dense (fig. 17). Stylet on 

 second abdominal segment (fig. 20) with numerous bristles but without 

 terminal spine. Median tail-process nearly twice as long as body ; cerci half 

 as long as body (fig. 1.). 



Length of body 14mm. Colour (with scalingj, darlv metallic purple with 

 white rings on feelers, cerci, and tail-process. 



Localities. — Mahe : Poret Noire district and Cascade, 1000 feet and over 

 (August, 1905, September and October, 1908) ; Montague Alphonse, Cascade, 

 1800 feet (December, 1905). Silhouette : forest near Mare aux Cochons, over 

 1000 feet (August and September, 1908). Praslin : Cotes d'Or Jungle 

 (November, 190'^). Specimens numerous in all these localities. Mr. Scott 

 records that they all come from mountain forests, mostly among the dead 

 leaves, both fallen and still hanging, of palms and other trees. 



This species is remarkable for the lateral extension of the jaws and 

 tongue The base of the mandible (fig. 4) has a strong prominence on its 

 outer border, while the tungue (fig. 5 hy) and the maxillulae (fig. 5 Mxl) are
