560 BRITISH 0KIBATID7E. 



plate is somewhat sufflexed on to the ventral surface 

 posteriorly, and has a small median point directed 

 forward over the anal plates. 



I am not acquained with the immatm^e stages of this 

 species. 



Distribution. — I have found a few specimens in moss 

 on the ground on the chalk hills near Gomshall, Surrey ; 

 this is the only instance that I know of when it has 

 been taken in England ; it has been recorded in Italy.

[This species is not the Hoplophora decumana of Berlese.] 



Length varies at least from about *5 mm. to about 

 1*30 mm., probably even more. 



Depth, from dorsal to ventral surface, of a specimen 

 1*10 mm. long, about '55 mm. 



This is the original species of Hoplophora, it is also 

 the common kind ; it varies so widely in size that I 

 hesitated to consider all as one species, but I am 

 unable to find any difference except size between the 

 specimens, and every intermediate size between the 

 extremes may be found, and E. anomala varies nearly 



* Dasypus, an armadillo ; from Saavg, hairy, and nov(, a foot.
