AMERICAN SPIDERS AND THEIR SPINNINGWORK. 



that one can tear it. Walckenaer found, August 20th, twenty-six spider- 

 Hngs perfectlj'^ developed enclosed within a cocoon. Each M'as about a 

 millimetre long, of a milk white color, the eyes not very distinct. In 

 another cocoon, found at the same period, he counted twenty-three eggs. 

 He saw no web near the tube in the neighborhood of the cocoons.^ Ex- 

 amples of the same mode of treating cocoons by the European Agroeca 

 brunnea have already been given. 



While walking through the fields near the home of Mr. F. M. Camp- 

 bell, at Iloddesdon, Hertz, England, I 

 noticed a number of pretty, spherical 

 nests which had been formed by mass- 

 ing together spikelets of a species of 

 grass. A ball about the size of a hick- 

 ory nut, that is to say, one inch in di- 

 ameter, was thus formed. At first sight 

 I took this to be the work of lepidop- 

 terous larva;, but upon plucking some 

 nests the spinningwork which bound the 

 spikelets together appeared to be spider 

 silk rather than that of a moth larva. 



One of the nests was therefore opened 

 and i)roved to contain a species of Dras- 

 sid which I took to be a Clubiona. 

 Unfortunately, the specimens which I 

 had preserved for further examination 

 Fici. 158. cocooning nest of wcrc lost, and I cau' only give this 

 an English Drassid, woven general identification. The species, as I 



upon tops of grass. (From , , . sr > 



Nature.) remembered it, seemed much like our 



American Clubiona pallcns, or the Eng- 

 lish Clubiona hollosericea. The drawings (Fig. 158) were made 

 from specimens which I brought home, and upon careful ex- 

 amination prove beyond doubt to be the home nest of a spi- 

 der, woven upon heads of a grass somewhat resembling maize, 

 probably Leersia oryzoides Swz., or Rice Cut-grass. When cut 

 open, a hollow sphere of white silk is disclosed, which is the dainty cell 

 in which the aranead lived. A veritable fairy palace ! Among the British 

 Clubionidffi, as described by Blackwall and Staveley, I can only find one 

 species, Clubiona erratica, whose habits would suggest such a nest as this. 

 The cocoon of this species is white and nearly round. The mother places 

 it in a nest, around which she forms a guard by binding together the 

 branches of firs or other plants in the midst of which she is placed. She 

 remains in the nest with her young. ^
