In this species, the figure represents the head rather

 microscope. The first three segments of the tail have 

 the infero-posterior angle produced to a point ; and the 

 inferior margins are furnished with a few equidistant 

 single hairs. The fourth segment of the tail has 

 the posterior dorsal margin produced to a small tooth. 

 The eyes are round. The superior antennae have the 

 first joint of the peduncle distally enlarged, whereas

 so long as the peduncle, and the secondary appendage 

 consists of but one long and one short articulus. The 

 second pair of antennae are imperfect beyond the 

 penultimate joint of the peduncle, but this reaches 

 beyond the extremity of the peduncle of the superior. 

 The first pair of legs are also imperfect. The second
