202 Falconer: The Spiders of Wicken, Cambridge. 
in addition to the commoner kinds, which may be expected to 
occur in their season, there is at least one other spider new to 
science, but its generic position is uncertain, a solitary 9 only 
having been taken (June). 
A morning was spent on both occasions in Edmund Fen, 
which adjoins the Burwell side of the ‘Ten Acres,’ and the 
following were met with in addition to the few, which are 
noted elsewhere :—-BoTH SEXxES—Clubiona holosericea Degeer, 
C. reclusa Camb., C. subtilis L. Koch, Prosthesima latreillit C. L. 
Koch, Zora letifera Falcr., Antistea elegans C. L. Koch, Theridion 
bimaculatum Linn., Robertus lividus Bl., Bathyphantes pullatus 
Cambr., Agyneta conigera Camb., Cidothorax gibbosus BL, 
E. tuberosus Bl., Maso gallica Sim., Dismodicus bifrons Bl., Tiso 
vagans Bl., Entelecara onissa Camb., Pocadicnemis pumila BL, 
Tapinocyba subitanea Camb., Pachygnatha degeerit Sund., 
P. clercktt Sund., Pivata piraticus Clerck, Lycosa pullata Clerck, 
L. farreni Camb., L. prativaga C. L. Koch, Neon valentulus 
Falcr., Sztticus caricis Westr., Marpessa pomatia Westr. 
MaLes—FEvigone atra Bl., Araeoncus humilis Bl. FEMALES— 
Leptyphantes ericaeus Bl., Gongylidiellum vivum Camb., G. 
murcidum Sim., Savignia frontata Bl., Wideria antica BL., 
Oxyptila flexa Camb., O. trux Bl., Tibellus maritimus Menge, 
Trochosa spinipalpis F. O. P. Cb. 
Nine species of harvestmen were noted, but only one, 
Oligolophus spinosus Bosc., was of any consequence. O. 
morio Fabr., and O. ephippiatus C. L. Koch were found to be 
frequent visitors in the evenings to the lepidopterists’ “ sugar ’ 
and illuminated sheets, especially the latter, roaming over them 
in search of the flies, etc., which settled on them. 
Several mites were also secured, and for their identification 
I sought the assistance of Dr. George and the Rev. J. E. Hull.
