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

single hairs. The fourth segment of the tail has

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
