Length, one-seventh of an inch. Colour, greenish yellow, with the 

 head in front blue. This is a remarkably large and stout species. 

 The anterior antennae leave the head at right angles with one another, 

 then bend outward a little, and then again forward, so that the tips 

 are also in lines at right angles with one another. The setae are 

 generally one to three diameters of the organ in length. The penult 

 setae, anterior and posterior, are nearly as long as the corresponding 

 joint, the antepenult are shorter, and the anterior antepenult is very 

 short. The pigment of the inferior eyes in a vertical view forms a small 

 short oval spot behind the superior eyes; and the latter are quite re- 

 mote, appearing nearly marginal. The caudal stylets are very short, 

 and the articulation with the abdominal oblique. The shorter branch 

 of the posterior antennae with its setce, is but little longer than half the 

 other branch. 



The specimen is a female ; and the eggs form two irregular series 

 either side of the body, which appear to meet over the mouth or near 

 it, and then separate into four branches extending towards the head. 

 The colour of the ova was yellowish. The lines did not extend into 

 the abdomen. 



There is also laterally, a blue spot near each of the three posterior 

 articulations of the thorax, on either side.
