plate, a pair toward base on sides of ventral plate, one each 

 side of the anus, and a long one behind on anal plate. Legs 

 long and rather slender, with scattered fine hairs. The peri- 

 treme is outwardly margined by a plate which extends a little 

 behind hind coxae. Ventral plate much broader behind than 

 in front, a little longer than broad, anal plate much broader 

 in front, long-pointed behind; the anus (broader behind) at 

 about middle cf anal plate ; an elongate metapodial plate each 

 side behind the peritremal plate. Length, 1*1 mm.

Body as broad as long or much broader, and very high 

 behind according to amount of distension, broadest at or 

 behind middle. Dorsum shows a shield much longer than 

 broad, and beyond its middle a transverse line, not reaching 

 either side ; dorsum without hair. Venter and margin with 

 many fine short hairs ; genital plate triangular", separated by 

 a line from the ventri-anal plate, latter broader than long, 

 broadest on anterior third, anal aperture at its tip. Legs 

 very short and stout ; first pair nearly as long as body, clothed 

 with many simple hairs, longer ones at tip of tarsus, other 

 tarsi rather blunt. Length, 1 mm.

Probably will form a new genus on account of shape of 

 ventral plate.
