and the Far West; but the following species is widely distrib- 

 uted. 



Misumessus asperatus (M. as-pe-ra'tus). — The female of

 in colour with dull red markings (Fig. 583) or the ground colour 

 may be greenish. There is a brownish stripe on each side of the

thorax; a median light red band on the basal half of the abdo- 

 men; two bands or rows of spots on the hind half; and a band 

 on each side. 



The male resembles the female in colour and markings but 

 is only about one half as long. The palpus of the male is large; 

 the embolus is long and coiled; in the unexpanded bulb it arises 

 from the distal end of the bulb; it is coiled downward and out- 

 ward over the lower edge of the cymbium, and the terminal 

 portion of it rests in a depression on the lateral face of the cym- 

 bium (Fig. 584). 



GenusOXYPTlLA (Ox-yp'ti-la) 



In this genus the median ocular area is longer than wide. 

 The legs are short and armed with but few spines; the tibiae 

 of the first and second pairs of legs bear only two pairs of inferior 

 spines (Fig. 585). The cuticle is clothed with setae of various 

 types, some of them are pointed while others are clavate or 

 spatulate. 



Seven species are now listed from the United States. In 

 Psyche, May, 1895, Mr. Banks published descriptions of six of
