534 REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 
CHEIRACANTHIUM ERRATICUM. | 
Clubiona erratica, Blackw. Spid. Gt. Brit. & Ir. p. 135, pl. viii. fig. 86, exclude references to Koch, 
Uebers., and Koch, Die Arach., as well as to Walckenaer. 
Two strong characters, given by Mr. Blackwall in his figures and description of this 
species, appear conclusively to distinguish it from C. carnifex, with which Mr. B. had 
supposed it be identical, viz. the abdomen in both sexes being marked with an oblique 
yellow line on each side, in addition to the normal macule, and the apophysis at the 
outer extremity of the radial joints of the palpi in the male being simply pointed, and not 
bifid or notched or cloven at their extremities. In other respects the two species appear 
to be very nearly allied to each other; but the types from which Mr. Blackwall's 
figures and descriptions were made having been unfortunately lost, it is impossible at 
present to give any more detailed or differential description. A recent communication 
from him, however, assures me that the two characters alluded to above are considered by 
himself to be good specific ones. These characteristics distinguish it from C. nutrix, 
Westr., and C. erroneum, Camb., as well as from C. Pennyi ejusd. 
Dr. Thorell (Syn. Europ. Spid. p. 210) calls attention to the distinctive characters 
furnished by the lateral abdominal stripes and the uncloven radial apophysis, and for this 
reason includes this species doubtfully among the synonyms of C. carnifex, Fabr. & 
Koch, and Cl. erratica, Walck. 
While correcting these proof sheets, No. 4 of Thorell’s ‘Synonyms of European Spiders’ 
has come to hand, at p. 432 of which he decides the present species to be distinct from 
Cl. erratica, Walek., and renames it Cheiracanthium fasciatum; but inasmuch as the 
name erratica, Walck., has become a synonym of C. carnifex, Fabr., there would not 
appear to be any need to give the present species a new name. 
Family DICTYNIDES=UINIFLONIDES (Blackw. ad partem). 
Genus DICTYNA (ERGATIS, BL). 
DICTYNA PUSILLA. 
Dictyna pusilla, Westr. Ar. Suec. p. 385; Thorell, Rec. Crit. Aran. Suec. p. 82. 
Although exceedingly similar in size and general appearance to D. benigna, Bl., 
and .D. uncinata, Westr., the present species may be readily distinguished from both, by 
differences in the relative length of the radial joint of the palpus (in the 3), as well as 
in the length and position of the spur with which the upperside of that joint is 
furnished. am 
An adult male was received in June 1872 from Dr. Capron, by whom it was found at 
Shiere, near Guildford, Surrey, and kindly forwarded to me. This is its first record as a 
British spider—though I have met with it before in England ; but the examples have 
been mislaid, and the exact locality has escaped my memory. 
Family AGELENIDES. 
Genus TEGENARIA, Walk. (BL). 
TEGENARIA CICUREA. 
Tegenaria cicurea, Koch, Die Arachn. viii. p. 40, pl. 264. fig. 620.
