lamellar lobe. In the species thus considered to be fixed as the 

 true interfector of Hentz the ectal margin of the cymbium lacks 

 spines ; the scabrous border ends proximally abruptly in a lobe 

 elevated above the general surface and on which the area of 

 prickles is broader, a very characteristic feature enabling one to 

 detect the species at a glance (Fig. 5). The form of the opening 

 of the epigynal pit is similar to that of hesperus, being partly sub- 

 divided by a projection from each lateral margin and thus differing 

 from that of notius. The spermathecae also present a caudal and 

 an anterior larger lobe connected by a narrower, weakly curved, 

 isthmus.

Mimetus notiiis, sp. nov. 



In this species the opening of the epigynum lacks projections 

 from its lateral margins, and the median dorsal strip is broader and 

 more conspicuous than, e. g., in M. interfector or M. hesperus; the 

 spermathecae are essentially longitudinal as shown in fig. 10. The 

 male differs from all the others here considered in having on the 

 distal portion of bulb of palpus only a single lamellar lobe, the ectal 

 one being absent or represented only by a slight tooth at base of the 

 developed lobe. The ectal margin of the cymbium lacks spines 

 proximad of the apex and its scabrous border runs out gradually, 

 not ending in any such abruptly elevated lobe as occurs in inter- 

 fector.
