NOTASPIS OBLONGA. 375 



Average length of legs (second and third pairs) about 

 •52 mm. 

 Average length of legs (fourth pair) about '68 mm. 



This species may be noticed by the short but con- 

 spicuous ridge-like lamellae near together and almost 

 parallel. It will be observed that previous authors 

 have considered it to be an Eremceus, to which genus 

 it undoubtedly has some analogy ; but I think that, in 

 spite of this, it is more properly included in the genus 

 Notaspis, subject to the remarks which I have made in 

 the introduction to the genus Eremaiis. It is a vary- 

 ing species. 



Colour dull red-brown or yellow-brown ; often with 

 a purple shade. 



Texture dull, without polish, but still smooth. 



Cephalothorax rather large and long, constricted 

 where it joins the abdomen ; the pro-vertex is particu- 

 larly distinct. Rostrum pointed, not very sharply. 

 There are two pairs of rostral hairs, both fine and 

 curved, but the hinder pair are considerably the larger ; 

 possibly these may be the homologues in some way of 

 the absent lamellar hairs ; although the position is not 

 quite consonant with this view. Lamellse two short, 

 nearly but not quite straight, almost parallel bars, 

 near together, and commencing some distance in front 

 of the pseudo-stigmata. Translamella a long bar, appa- 

 rently not quite joined to the lamellee. Pseudo-stig- 

 matic organs rather long, with slender peduncles and 

 fusiform heads ; both peduncles and heads are rough- 

 ened with small spines. Interlamellar hairs cortsider- 

 ahly shorter than pseudo-stigmatlc organs ; they are 

 curved, very close to the pseudo-stigmata, and slightly 

 rough. Tectopedia well developed, the third pair form 

 strong, bifid-headed projections behind the second pair 

 of legs. Apodemata very strong, and distinctly joined 

 to the sternum, which is also large. The dorso-vertex 

 between the pseudo-stigmata is somewhat raised and 

 rough.
