A HISTORY OF SUFFOLK 

 ARACHNIDA 



spiders, Harvestmen, False Scorpions, and Mites. 



No specialist, so far as I am aware, has ever worked at the Arachnids in Suffolk. Many years 

 ago, while entomologizing in the neighbourhood of Lowestoft and of Bury St. Edmunds, I observed 

 numbers of the commoner species of Araneidea, but at that time — 1849-50 — I had not seriously 

 begun to pay special attention to this group, and unfortunately have no records of the species met 

 with. Both the districts referred to were evidently such as would abundantly repay careful working. 

 The following list has been drawn up almost entirely from various collections of spiders sent to me 

 for identification between 1 90 1 and 1904 by Mr. Claude Morley of Monk Soham, Suffolk, and 

 collected by him during his entomological researches in difiFerent parts of the county. The list con- 

 tains one fiundred species of Araneidea (True Spiders), seven species of Phalangidea (Harvestmen),, 

 three species of Chernetidea (False Scorpions), and two of Acaridea (Mites). This is but a. 

 meagre representation of the British spiders (whose numbers as at present recorded amount to about 

 550 species). Among those now recorded for Suffolk some few are local and rare, and one {Tmeticus 

 commodus) appeared to me to be undescribed at the time I received it ; but the greater number are 

 among the species more commonly and generally distributed. Seven of the Phalangidea are repre- 

 sented out of twenty-four recorded British species, and only three of the twenty or so recorded 

 British Chernetidea (False Scorpions) ; while of the Acaridea (Mites) only two can be named. 



For further information upon the systematic arrangement, nomenclature, synonyms, and other 

 details of the species in the subjoined list, I may refer to the following English publications : — A
