196 SUPPLEMENT TO 



describes tlie Mentonese form under the name of Ct. 



The females of the true Cteniza fodiens 2iX^i2x\2iX^QY 

 than those of our new Mentonese species, and con- 

 struct their nests in dry and exposed places, instead 

 of in the moist and shady ivy-covered hanks selected 

 by the latter. I have found Cteuiza Mcggridgii at 

 San Eemo and Mentone, and it will probably be also 

 discovered at Nice, but I failed to detect it either at 

 Cannes or Hyeres. 



The Corsican male at the first glance curiously re- 

 sembles that found at Mentone, but differs essentially 

 in details and especially in having the surface of 

 the caput unbroken, whereas the caput of the 

 latter presents a very peculiar character in an 

 impressed line which runs across it from side to side 

 (figs. A 1 and A 2). Both agree, however, in being 

 strangely unlike their females. 



The other builder of a nest of the cork type at 

 Mentone was, as has been already stated, described 

 and figured in Ants a7id Sjndefs under the name of 

 Nemesia camentaria. Now the true N. camentaria of 

 Latreille is found at Montpellier, the classical habitat 

 where the first discovery of trap-door spiders in 

 Europe was made tov/ards the end of the last century, 

 but its true characters have been hitherto but im- 

 perfectly known. 



I have lately been able to secure several specimens 

 at this place, and they certainly differed in their 



naming and describing my collections of trap-door spiders, and the results of 

 his labours will be found at the end of the present work. 



* I take this opportunity of thanking him for the compliment. A descrip- 

 tioa of this new species will he found at p. 254, below.
