 hairs absent. Furcula absent. Abdomen ending in four large 

 rounded tubercles (fig. 4). Head with 12 tubercles (figs. 4, 224) as 

 follows: A small tubercle betweeii the bases of the antennae; a 

 transverse row of five, including the ocular tubercles and a large 

 median tubercle; a transverse posterior series of six, in which the 

 two dorsal tubercles are small. Basal antennal segment with a 

 dorsal tubercle; second segment with a trace of tuberculation. 

 Prothorax with six tubercles, the dorsal pair being minute. Meso-
