white band around the front and two white spots on each side. 

 The mandibles of the male are much elongated and bent apart 

 at the ends to make room for the long claw. At the inner 

 angle is a large tooth, and there is another one of complicated 

 shape on the middle of the under side. 



Phidippus multiformis. — This is a very common spider on plants 

 throughout the summer. It matures in July, and the males and 

 females are so little alike as to be taken 

 for different species. The males (fig. 

 134) are black, with white and orange 

 markings on the abdomen, while the 

 females are brown mixed with black, 

 white, and yellow scales and small 

 white spots. 



The usual length is about a third of 

 an inch in both sexes. The cephalo- 

 thorax is nearly as broad as long, and 

 the abdomen of the female as wide as 

 the thorax and a little longer. 



The general color of the adult female 

 is yellowish brown, with black and white 

 markings (fig. 133). Around the front 

 of the abdomen is a white band, and on 

 the back are two indistinct longitudinal 

 black stripes in which are four pairs of 

 white spots. The general brown color 



is produced by a mixture of scales and hairs of various colors. 

 The females are most brightly colored just before reaching 

 maturity, and then there is a large proportion of yellow and 

 orange scales in their covering and the black stripes and white 

 spots are more distinct. The hairs and scales are of various 

 shapes, the most common being that of slightly flattened hairs. 

 The yellow and orange scales are wider and less pointed, and
