448 BIllTlSH ORlBATIDiE. 



I have found the species generally distributed and 

 not uncommon. 



The species was originally found in France, and has 

 not to my knowledge been recorded elsewhere, except 

 by myself. 



Nicolet figured and described a closely allied species, 

 which he called H. granulata, which was distinguished 

 from H. arrecta chiefly by the possession of a square 

 plate or shield on the vertex : this species has been re- 

 corded in Italy by Berlese and in Germany by Haller. 

 I have not seen such a plate on any EngHsh specimens, 

 but the two, almost obsolete, rough, longitudinal ridges 

 on the cephalothorax above mentioned, seem a little 

 like a relic of it.

Average length about "82 mm. 

 Average breadth about '50 mm. 

 Average length of legs (first and third pairs) about 

 •38 mm. 



Average length of legs (second pair) about '35 mm. 

 Average length of legs (fourth pair) about "40 mm. 



I cannot say why Nicolet altered the name of this 

 species from Koch's name of "|n'ce?is," with which he 

 identifies it, to " crassipes.^^ Of course Nicolet's name 

 cannot stand. I have followed Nicolet and Haller's 

 synonomy in adopting picea in preference to convexus 



* Piceus, black as pitcli (Caligo picea, Yirg.).
