stripe. The form of the epigynum is shown in Fig. 720, a. The 

 male measures one third inch in length; the female, one half inch. 

 The known range of the species extends from Massachusetts to 

 Texas. 



Lycosa cinerea (L. ci-ne're-a). — The body is clothed with 

 white, gray, and black hairs intermixed in spots and streaks; 

 on the cephalothorax the spots radiate more or less from the 

 median furrow; on the abdomen the markings are very irregular. 



This is a European species which has also a wide range in 

 this country. It is found on beaches and in sandy fields, where its 

 colour and markings are protective. 



Genus PI RATA (Pi-ra'ta) 



The anterior tibiae is armed with two or three pairs of spines 

 beneath, but the distal pair is never apical in position, although 

 there may be a subapical pair in the male. The anterior eyes are 

 in a straight or slightly procurved line; they are subequal or 

 the median are a little larger than the lateral. The labium is 

 longer than wide, with the basal excavations short. The epigy- 

 num of the female presents no true guide, but usually bears behind 

 two strongly chitnized lobes or tubercles upon which are the open- 

 ings of the spermathecae (Fig. 724).
