 (Rye)'; Charlton pit, Kent; Hayling Island (E. Saunders); Watermouth, North

The shape of the head will distinguish this species from all its allies 

 except H. Eichqffi', from which it may at once be separated by its more

Very common throughout the country ; found in flood refuse, haystack refuse, 

 decaying sea-weed, moss, at roots of grass, &c. 



As mentioned above, the elongate first joint of posterior tarsi and the
