which, beside being circular, has in its midst a zigzag band, 

 which traverses it from top to bottom. This spider is a 

 little larger than the diadema. The abdomen of the female 

 is of a very brilliant yellow, contracted near the corslet 

 where there is a little of a silver color, and it has about ten 

 black bands somewhat slashed. Fig. 9 represents the male 

 of the same species, much smaller than the female. Its color 

 is the same, but the marks caused by the folding of the skin 

 of the abdomen, are more confused. The palpi are larger, 

 and terminated by a somewhat oval protuberance. Fig. 10 

 represents the palpi closed ; fig 1 1 shows all the internal pro- 

 vision for extending itself out with compression. In fig. 12 

 is seen the sexual part of the female, superior at a, inferior, 

 that is toward the abdomen, at 6. Being compressed, it 

 appears to extend itself out, divided into two lobes (fig. 13, 

 a and b), but in a side view it has the figure 66, and is seen 

 tulla uncinata (held grappled). The structure of the 

 cocoon of this spider is also to be seen represented in 

 fig. 14. Villiers, 14 1 know not why, represents the spider, 

 under the name of Aranea formosa, much smaller than the 

 cocoon, but I have represented both of their true dimen- 

 sions. It (the cocoon) is found covered with a gum easily 

 soluble in warm water, but insoluble in cold. The floss, 

 which projects upon the upper part, serves to attach it to 

 the bodies under which the spider conceals it. In fig. 15 

 is seen the same cocoon split open, and it is to be observed 

 that the receptacle for the eggs is in the middle, surrounded 

 by yellowish silk, and in the centre, of the color of coffee, 

 protected on all sides from destructive insects and from 

 water. 



The female of the zucca spider (Aranea cucurbilina L.) 

 is represented in fig. 16, and in fig. 17 the male. In fig. 18 

 is seen one of its palpi, closed at a, and on the side at 6, 

 looking toward the concave part at c, elongated, and at d 

 entirely stretched out during compression. Fig. 19 shows 

 the sexual part of the female. This spider forms small and 

 yellowish cocoons.
