CASE Another very curious species like the preceding. It also is a 



XIII 



very common species in the neighbourhood of Paris. We are not 

 aware that these have yet been found in Britain — ^but they are 

 worth looking for on account of their remarkable structure and 

 habits. This one is especially found in damp moss — and no 

 doubt the covering of dirt on its back is designed as a protection 

 from too much dryness or heat. A species has been described by 

 Thorell from Spitzbergen, under the name of Nothrus borealis.

Another curious, heavy, lumpy insect common in the neighbour- 

 hood of Paris. It is distinguished by rows of flat spatula-shaped 

 hairs on its body and legs. It also affects mosses. 



This genus also is represented in Spitzbergen, a species named 

 H. reticulata having been described by Thorell. 



Genus Cepheus {Koch), 



Same character as Notaspis, but the tectum attached to the 

 cephalothorax only by its base.
