This fine Philodromus has been unusually abundant during 

 the past autumn (1881) on Bloxworth Heatli 5 but, although 

 I have examined numerous examples from time to time up to 

 the 1st of November, no male in the adult state has been yet 

 met with. Some few of the females were adnlt on the 17th 

 and 31st of October ; but all the males had the digital joints of 

 the palpi still in a tumid state. On the day last mentioned I 

 placed four males alive in separate bottles, and have since fed 

 them with flies; they are up to the present time (December 5th) 

 well and active ; but the palpal organs are still undevelo])ed, 

 leading me to conclude that they do not attain complete matu- 

 rity until the early spring.
