506 J. H. KEYS. 
40 specimens. July, 1901, 23 specimens; July, 1902, 9 specimens. 
The species is gregarious, but its minute size, 1} mm., makes it 
easily overlooked. Mr. J. J. Walker has taken it on several occasions 
at Falmouth. 
TSIPALIA TESTACEA Bris. Batten beach under stones below high tide, 
and Millbrook Creek in the shingle at roots of rushes at high-tide 
mark. I have taken this rare species from March to September. 
tARENA ocTAviI Fauv. Dawlish Warren, de la Garde, April, 1907, one 
specimen under dry tidal rubbish, and a few specimens in later 
years. 
{*PHYTOSUS SPINIFER Curt. Tregantle in April and May and again in 
August, occasionally in considerable numbers ; Bovisand, one only, 
July, 1912, and one only, May, 1913; Stoke Bay, June, 1916, 
one only. De la Garde, Shaldon, February; Dawlish Warren, 
April. G. C. Champion, August-September, 1907. 
7*P. Batticus Kr. Under seaweed and in the sand below it with the 
above species, often in numbers, at Tregantle. Dawlish Warren, 
plentiful, March, 1907, and later years, de la Garde. August- 
September, 1907, G. C. Champion. 
{P. NIGRIVENTRIS Chevr. With the above at Tregantle, but not so 
abundant. Dawlish Warren, de la Garde, March, 1907, and later 
years. 
{DieLorra MeRSA Hal. Batten, once only, a single specimen in April, 
1892 ; under stones much below high water, Millbrook Creek, very 
sparingly, in May, 1900, 1907, 1909. Dela Garde has taken it freely at 
Dawlish Warren. In June, 1909, at the latter locality I obtained a 
large specimen, 24 mm. long, possessed of fully developed wings, 
the length of each being 2 mm. with a maximum breadth of 1 mm. 
Apparently this form is extremely unusual. Vide G. C. Champion’s 
remarks thereon, Ent. Mo. Mag., Vol. XXXYV., pp. 264-5. 
THETEROTHOPS BINOTATA Er. Jennycliff; Batten; Downderry. 
Shaldon, de la Garde. 
*(QUEDIUS UMBRINUS Er. This uncommon species, which Fowler (Col. 
Brit. Isles, Vol. II., p. 241) says: ‘‘ Appears to be chiefly found in 
wooded and hilly or mountainous districts,” I once found in con- 
siderable numbers at Millbrook Creek in the little salt marsh beyond 
Palmer’s Point in August, 1900. G. C. Champion also records it 
from damp places on the cliffs, Shaldon (Ent. Mo. Mag., 1908, p. 33). 
*(). SEMIHNEUS Steph. Slapton; Tregantle; single specimens fre- 
quently, Millbrook Creek; by the Yealm. Shaldon, de la Garde.
