[Mr. Smith's collecting is done at his home in Sherborn, Mass., near the Natick line. 

 The locality is in a farming community (street-lights absent) and presents the usual diver- 

 sity of environment characteristic of the sand-plain area of eastern Massachusetts : — 

 orchards, fields, gardens and shade-trees; gravelly plains and ridges sloping down into 

 sedgy meadows through which wind sluggish, alder-fringed streams ; peat-bogs, bushy 

 swamps, and woodlands consisting now chiefly of a young growth of deciduous trees but 

 formerly containing large tracts of white pine. The elevation is about 170 feet, dropping to 

 140 at the streams, and rising to 260 or even 400 at distances of half a mile to a mile and a 

 half in boulder-strewn hills of unmodified drift, with occasional outcrops or of drumliii for- 

 mation. A. P. M.] 



Change of Marking in the Males of a Spider {Pellenes cristatus). The 

 peculiar markings of the male appear in many species of spiders after the moult 

 before the last when they are not more than half grown, and after the last 

 moult these markings become more distinct and deeper in color. In PeUcnes 

 cristatus, however, the young male before the last moult has a bright red spot on the 

 front of the head below the eyes which disappears entirely when it becomes adult. 

 I first noticed these spiders in the autumn of 1901 in their silk nests under 

 sticks on the edge of the salt marshes at Ipswich, Mass. In the following spring 

 Mr. G. W. Peckham visited Boston and he and I went on June 17 to the same 

 place at Ipswich where we found again the young males with red faces and with 

 them adult males with black faces and dull gray and drab markings. We thought 

 at the time that the young males were Pellenes caecutus, a common species south 

 of New York in which the face has a similar red spot both in young and adult 

 males. Mr. Peckham afterward identified the black males as Pellenes cristatus 

 supposed to be the same species as Attus cristalus described by Hentz. 



In the spring of 1903 I went to the shore earlier in the season and about 

 the first of May found the black males abundant in the dead grass washed up 

 by the tide along the edges of the marsh and with them an occasional young 

 male with a red spot on the face. I took these home alive and one of them 

 soon moulted and came out a black male P. cristatus without any trace of the 

 red marking. — /. H. Emerton.
