Mimetus inter fector Keyserling (in part, including those fig- 

 ured), Spinnen Amerikas, Theridiidae 2, 1886, p. 6, pi, 11, fig. 137. 



This species is in the female sex at once distinguishable from 

 all the others in having the epigynal pit at the caudal apex and 

 visible as a median notch from below (Fig. 6). The male may be 

 separated from the other species occurring in the eastern and 

 southern States by the presence of two subapical spines on the ectal 

 margin of the cymbium; and from the western hesperus, as indi- 

 cated above, by the position of the more proximal of these spines 

 and the form of the larger lamellar lobe of the bulb, which is unlike 

 that of any other species (Fig. 1).

Mimetus epeiroides Emerton 



Trans. Conn. Acad. Sci., 1882, 6, p. 17, pi. 3, fig. 4. 



Known only from the male which is clearly distinct from the 

 other species in characters of the palpus. In this the ectal margin 

 of the cymbium possesses a single spine toward the basal lobe, in 

 distinction from the two preceding species in which there are two 

 spines on the margin, and from the two following ones in which 

 there is no marginal spine proximad of the distal one. The ectal 

 border is scabrous over its entire length from apex to basal spine. 

 The terminal portion of bulb bears two lamellar lobes, both of which 

 are simple. 



Type Locality. — Mass. : Essex. 



Immature specimens referred to this species have also been 

 taken by Mr. Emerton at other places in eastern Massachusetts and 

 at Providence, Rhode Island. 



Mimetus interfector Hentz 



Journ. Boston Soc. Nat. Hist., 1850, y, p. 3, pi. 4, fig. 12. 13. 



Mimetus tuberosus Hentz, ibid., p. 3, pi. 4, fig. 14. 



Of each of the two species of Mimetus occurring commonly in 

 the southern States, individuals may be found which match the fig- 

 ures of interfector given by Hentz reasonably well. I believe the 

 species to be fixed, however, by the figure of the palpus of the male 

 which, in spite of its general inadequacy, shows two prominent 

 lobes projecting proximad from the bulb that are apparently the 

 two lamellar lobes present in the one species, whereas in the other 

 species, listed below as M. notius, sp. nov., there is but a single
