YI. — Some Spiders and Mites from the Bermuda Islands. 



By Nathan Banks. 



The following pages contain a list of some spiders and mites 

 collected in the Bermudas by Prof. A. E. Verrill and some of his 

 assistants. Most of them were gathered the past spring, 1901.* 



Several of the spiders are immature, so that they cannot be fully 

 determined. Three of the spiders are described as new. There are 

 twenty-eight spiders in the list, which is more than twice as large as 

 any previous list. They are distributed in sixteen families ; the 

 Theridiidse, with six species, leads in point of numbers ; eleven 

 families are represented by but one species 



John Blackwall recorded six species of spiders from the Bermudas 

 in 1868.f They are as follows : 



1 . Loxosceles rufescens Lucas. + 

 •2. Epe/'ro > f/mcilijH-x Blackw. + 



3. Thomisus pollens Blackw. + 



4. Salticus diver sus Blackw. 



5. Heteropoda venatoria Linn. 



6. Filistata depressa Koch. 



His Epeira gracilipes, which was originally described from Rio 

 Janeiro, is probably the common Epeira theisii Walck. The Filis- 

 tata depressa is the same as F. hibernalis Hentz; while his Salticus 

 diversus is a synonym of Plexippus paykvdli And. and Sav. 



In 1889, Dr. George Marx reported on the spiders collected in the 

 Bermudas by Prof. Angelo Heilprin.J 



He had twelve species, as follows : 



J . ZTloborus zosis Walck. 



2. Wephila clavipes Koch. 

 •">. Cyclosa eaudata Hentz. 



4. Epeira labyrinthea Hentz. -f 



5. Theridium tepidariorum Koch. 



* These collections were made in April and May, 1898, and. from March 10th 

 to May 9, 1901. Probably many other species conld be found in summer and 

 autumn. — A. E. V.

 Proc. Acad. Nat. Sci., Philad., 1889, pp. 98-101, one plate. Heilprin's collec- 

 tion was made in midsummer. Prof. Verrill's in the spring. This may account 

 for part of the difference.
