Epeira cincfacta Scudder. 

 Scudder, Tertiary Insects, 1890, p. 85, Plate 11, fig. 16 ( 5 ). 



One male from Florissant, Nos. 8576 (now No. 108) and 8806 

 (now No. 109). 



Scudder's description is correct. The appearance of the speci- 

 men reminds one rather of recent Mangora than Epeira.

Scudder's description is correct. As he omitted to give a figure 

 of the spider it seemed to be advisable to give one now. It may be 

 added that the spinnerets appear as a dark brown disc a little in 

 advance of the posterior end of the abdomen. An interesting fea- 

 ture is the dark line slUM-ounding the disc and reminding one of 

 the circular wall around the spinnerets in recent Gasteracantha.
