Ep. diademata. Other writers have by the name Ar. obtextrix or 

 obtectrix meant other, or have confounded several, species: Ar. ob- 

 tectrix Strack ') for example is the same as Pachygnatha DeGeeri 

 Sond. (Vid. inf.: Pack. DeGeeri Westb.). The first who speaks of 

 an "Ar. obtextrix* appears to have been Bechstein 2 ) , who has under 

 that name described certain small spiders, which he (erroneously) 

 considered to be the sole causers of the phsenomenon so well known 

 under the name of "gossamer," "fils de la Vierge," "fliegender Sommer." 

 This Ar. obtextrix Becbst. probably includes divers species of the 

 genera Wabikenaera ( Micryphantes) and Erigone. 



E. lutea C. Koch, adduced by Walckenaee as synonymous with 

 E. diademata, is quite a different species (Vid inf., p. 17).
