Trichoniscus roseus (Koch). — Widely distributed, and some- 

 times found in considerable numbers. This species is very 

 attractive in consequence of its beautiful colour, which I have 

 found to range from light orange to blood red. Some specimens 

 from locality (1) are almost quite white. They were in com- 

 pany with T. pusillus under a decayed log of wood. The 

 situation was in quite open ground, and I cannot, therefore, 

 account for the abnormal coloration. Females with ova during 

 the months of July, August, and September, and many young 

 individuals during these months.
