17G AMERICAN SPIDEKS AND THEIR SPINNINGWURK. 



No. 33. Epeira linteata, new species. Plate VIII, Figs. 5, G. 



Fkmai.e: Total length, 4 mm.; alxlomen, 2.0 mm. long, 2.0 wide, narrowing to 1 mm.; 

 ceplialothorax, 2 mm. long, 1.0 wide; about the face, 1 mm. wide. 



Cephalotiiorax : Corselet a rounded oval, peaked in the centre, sloping sharply down 

 behind, with a smooth flat surface, and with almost an equal slope toward the front; fosse 

 almost obliterated; cephalic suture not prominent; corselet grooves indistinct; color yellow, 

 with streaks of brown; caput and face covered with long yellowish-white hairs. Sternum 

 shield shape, truncated in front; sternal cones; yellowish brown ; slightly pubescent ; labium 

 sub-rectangular at base and triangular at tip; maxilUo rounded at margins; as broad as 

 long ; color as the sternum. 



Eyes : Ocular quad without a decided prominence ; its eyes about equal in size ; the 

 front about equal to the length and a little wider than the rear. MF dark colored, sepa- 

 rated by about 1.5 diameter; MR amber, and separated by about one diameter. Side eyes 

 about e(iual in size, placed on a slight tubercle ; SF separated from JMF by about the area 

 of MF; the two eyes contingent, and SR so nearly on a line with SF that they seem to be 

 grouped rather with the front than the rear row. The space between SR and MR equals 

 at least three, perhaps four, times the space between MR. The front row of eyes is almost 

 aligned, being only slightly recurved ; the rear row is much procurved ; clypeus high, its 

 margin separated from IMF eyes by about twice their diameter. 



Legs: 1, 2, 4, 3; stout for so small a species; armored with yellow spines and long 

 bristlelike hairs; the joints appear to lack annuli, but my specimens have been much 

 injured in the alcohol. ^Mandibles subconical, diverging slightly at the tips, a little reced- 

 ing beneath. 



Abdomen: Subtriangular, and without dorsal tubercles. At the widest part it is about 

 as broad as long; is highly arched, rounding from the cephalothorax to the apex, and 

 marked by a broad, white, capelike folium, with denticulate edges, extending from the 

 spinnerets to the base, and overlapping the basal front in a scalloped point. (Plate VIII., 

 Fig. 5b.) This white patch is broken in the centre by a dark interrupted band, dividing 

 on either side of the median line. The sides, like the centre, are yellow brown, marked 

 with reticulations at the venter. The epigynum has a short scapus broadened at the tip 

 (Figs. 5c, 5d), and appears to proceed from a bowl shaped atriolum, that in one specimen at 

 least (5d) seems to pass out beneath. 



Male: The male (Fig. 0) difl'ers little in its markings from the female. It is somewhat 

 smaller in size, and is distinguished by a palpus whose digital bulb is given at Fig. 6b. 



This species resembles in many particulars E. miniata, but differs in the form of the 

 eyes (5f ), especially in the location of the rear lateral eyes. It also lacks the well developed 

 dorsal tubercle upon the base of the abdomen which characterizes E. miniata, and the 

 epigynum is distinctly different. The species is probably a little more closely related to 

 Emerton's Epeira aiboventris. 



DisTRiBUTiox : The only specimens which I have, four females and one male, were col- 

 lected in North Carolina. 



No. 34. Epeira corticaria Emektox. Plate VIII, Figs. 7, 7a-d. 



18S4. JCjieim corticaria, Emertox ... X. E. Ep., p. 300, pi. 33, Fig. 14 ; pi. 35, Fig. 9. 



Female: Total length, 7 mm.; abdomen, 5 mm. long, 5 mm. wide; cephalothorax, 

 2.5 mm. long, 1.5 mm. wide. 



Cephalothorax: Longer than broad; rounded at the edges; cephalic suture deep; 

 somewhat flattened on the top; the fosse well marked; corselet grooves not prominent; 

 color yellow, with a patch of brown around the fosse and on the base of caput; head but 

 little depressed, wide in front. Sternum dark or blackish brown, with decided sternal 

 cones, slightly covered with yellow pubescence ; labium subtriangular ; maxilUe slightly 

 longer than broad, and subtriangular at the tip.
