length, broad, and flat. The rostrum blunt, the tectum large and 

 well marked, its wings (or lamellae) very large, nearly on edge, and 

 projecting far beyond the anterior edge of the horizontal surface of 

 the tectum ; at their anterior termination these lamellas are trun- 

 cated and slightly rounded, from the lower angle of the truncated 

 edge springs a stout spine, which curves forward and downward, 

 and almost touches the tip of the rostrum. A little above this 

 spine, on the same truncated edge, is a much thinner but rather 

 longer spine, or hair, almost parallel to the thicker one. Each 

 lamella increases in width as it nears the abdomen, and terminates 

 suddenly, with a rounded shoulder, just in front of the stigma. 

 The stigmata are placed at the junction of the cephalothorax and 

 abdomen, they are very large and open : the opening faces straight 

 upward. The stigmatic organs (or hairs) are globular, and are 

 sunk in the mouth of the stigmata, which gives each stigma the 

 appearance of being an enormous eye — it is from this effect that I 

 have named the species. This peculiarity alone would be sufficient 

 to distinguish the present species at a glance from every other 

 which I am acquainted with. The interstigmatic hairs are short 

 spines just inside the stigmata. The palpi are subcylindrical, 

 with the first joint much the longest, the third and fourth very 

 short, the fifth conical and densely haired, labium longer than 

 broad, mandibles very small. 



The legs are stout, all joints except the tarsi very rough and 

 irregular in outhne, the second joints much the thickest, the tarsi 

 short and stout. The first two pairs reach considerably beyond 

 the rostrum, the fourth pair only slightly beyond the posterior 

 margin. The tarsi are clothed with numerous very thick hairs^ 

 the other joints have very few hairs on them. 



The abdomen is oval, truncated anteriorly, with the antero- 

 lateral angle produced so as to form short points projecting 

 forward and almost touching the stigmata. There is a broad 

 flattened margin, somewhat raised towards the edge, all round 

 the abdomen, except where it joins the cephalothorax ; this band 

 bears a row of blunt spines, not quite regularly arranged ; icside 

 the band the notogaster is arched, but not very strongly ; it is 

 divided by ridges into irregular strips or bands, of which one or 

 two run nearly parallel to the anterior margin and the rest run 

 more or less longitudinally. There are usually about ten bands in 

 the width ; each band contains two rows of round pits, the position 

 of the pits being alternate, i. e. the pits in one row come between, 

 and not opposite to, the pits in the adjoining row. The anal 

 plates are very large, and the genital plates are close to them ; 

 both sets are sub-oblong in form.
