AMERICAN APTERA. 69 



Easily separated from the otlicr banded species of the genus by its 

 small size and peculiar pattern of markings. 



Bol.vplisiiilOM piit'ific'iis nov. sp. — Length %, 2. mm. Ccphalothorax, 

 legs and iialpi wiioUy reddish ; abdomen black, with small pale spots, and a large 

 transvi'i-se wliite one a little above the ])ale spinnerets. Head prominent with 

 some scattered granules above; a large projection just behind the eyes, with sev- 

 eral short hairs and a long, stiff, curved bristle at tip ; ])osterior row of eyes barely 

 recurved ; p. m. e. fully their diameter apart, and about as far from the p. s e. ; 

 in % hardly tlieir diameter aiiart, and closer to the p. s. e. ; a. m. e. small and 

 about their diameter ajnirt ; sternum very broad in front, blunt pointed behind. 

 Legs long and slender; % abdomen more than twice as long as broad: the 9 

 lacks the granules on the head, and the large oval abdomen has no white spot; 

 the ejiigynum shows a i)air of rounded lobes behind, and in front and partially 

 lying upon them is another pair closer together, each outerside of the latter pair 

 there is a small black hole ; the % pali)us is similar to B. dra.ssoides Em. ; the 

 projection to the tibia is not so long and proportionally broader ; the liook of the 

 tarsus extends back to the base of the tibia, but is stouter than in B. drassoides, 

 and there is no other tooth ; the tube starts as in B. drassoides and exteuds upward 

 along the lineated piece.

Plcctaiia voiiiiNfa nov. sp. — Length 7 mm., ceph. in front 1.8 mm. 

 Cei)halotlior;ix jiale yellowish, brown each side; abdomen yellowish, a brown 

 spot near base, a broad whitisli band and behind a triangular brown spot, some- 

 times a whitish stripe from basal s])ine and then a brown folium ; venter brown,

 banded with brown ; ccphalothorax nearly twice as long as broad ; sternum once 

 and a half longer than broad. Abdomen plainly longer than broad, with the 

 same number of jjrojections as in P. stellafa, but four of them very much enlarged, 

 viz., the median one at base, one at each anterior corner, bifid at tip, and the 

 apical one over the spinnerets, on each side are three small humps ; the epigynum 

 has a finger similar to P. stellafa. 



One female and two young, Punta Gprda, Fla. (INIrs. A. T. Slos- 

 son). Related to P. stellata, but easily distinguished by its much 

 narrower body and the enlarged s[)ines on the abdomen above.
