Affecting the same localities as Philodromus variatus, this spider 

 pairs in May ; and in June the female spins a cell of white silk 

 in which she constructs a lenticular cocoon of a slight texture, 

 measuring |th of an inch in diameter, and deposits in it between 

 60 and 70 spherical eggs of a pale yellow colour, not agglutinated 

 together. A near resemblance may be traced between Philo- 

 dromus mistus and Philodromus cespiticolis, Walck. (Hist. Nat. des 

 Insect. Apt. t. i. p. 555).
