spiderlings, and at 7.00 there were about twenty upon her. Next day 

 at 9.00 A.M. more young were still emerguig, and at 3.00 P.M. she 

 dropped the cocoon (empty of young) from her spinnerets. The young 

 massed together upon her abdomen and cephalothorax made her 

 appear twice her natural size ; she did not allow them to get upon her 

 eyes, however, but brushed them away gently with her palpi. On 

 July 2 the first of the spiderlings left her, running down her legs to 

 the ground, and on July 4, when I killed her, only five were left upon 

 her; these I endeavored to rear by keeping them in separate tubes, 

 but all of them died within a few days. 



9 No. 211 was found on June 16, at 2.45 P.M., resting her cocoon 

 (attached to her spinnerets) upon the floor; some of the young on 

 emerging from the cocoon got upon the floor, but these quickh' climbed 

 up the legs of the mother. She dropped the cocoon next day, and 

 examination showed that she had ^gnawed it along its whole circum- 

 ference, but at only certain points along the line of the abrasion had 

 holes been made to the interior cavity. In this case, as in the pre- 

 ceding, the young that had left the mother's constructed a network of 

 silken lines through the cage; possibly aeronautic lines, such as young 

 Lycosids normally employ to carry them, with the help of the wind, 

 away from the home of the mother. 

 Lycosa punctulata Hentz. 



One female of this, locally rather rare, species was kept and observed 

 from June 10 until her death on August 3. 



Cocooning. — On July 1 and 2 she was found spinning upon the floor 

 of the cage. On July 3, at 11.00 A.M., I found she had quite a thick 

 sheeting over the floor and for a little distance up the sides of the 

 cage, covering an area of about 25x65 mm. At 1.33 P.M. on that 

 day I found she had constructed an oval disk of white silk (cocoon 

 base) with a diameter about equal to her body length; this base was 

 placed upon the preUminary scaffolding in the corner, and inclined to 

 the floor at a slight angle. From 1.33 to 1.46 she spun a silken wall 

 upon the margin of this base, though when finished it was barely 

 visible to the naked eye. She composed it of looped threads, made 

 by uplifting her spinnerets high at each stroke. She then stood over 

 the centre of the base, and from 1.47 to 1.50 there fell upon the center 

 of the base from her genital aperture a clear drop of viscid fluid, into 

 which fell in succession a number of pale yellowish ova; a second 

 smaller drop from 1.51 to 1.52; and from 1.52 to 1.53 five small drops 

 in succession, each enclosing one ovum. All the drops merged together 

 upon the cocoon base, but the whole mass was small in proportion to
