Zilla x-notata, Z. atrica. 



Z. x-notata described in Trans. Conn. Acad., Vol. VI, 1884 from 

 Woods Hole, Mass. is abundant at Provincetown, on wharves, barns 

 and houses near the shore ; also at Wellfleet and Harwich and at 

 Newport, R. I., on the street fences ; New Bedford on wharves and 

 fish houses ; and Fall River on boat houses, but in small numbers. 

 None were found at Dighton and Taunton. On the same street at 

 Newport where Z. x-notata is found on the fences Z. atrica occurs 

 in hedges. It is also common at Fall River on hedges, fences and 

 garden shrubs. At Taunton this species was absent, as well as 

 x-notata. 



Dictyna terrestris, new. 



2 mm. long and resembling closely D. volupis. The front middle 

 eyes are farther forward than in volupis, so that the middle eye 

 area is longer than wide. PI. IV, figs. 3c, 3d. The male palpus 

 has the tibia short, not longer than wide, except on the outer side. 

 The tarsus and palpal organ are ver)' large and both curved down- 

 ward more than in vobipis. Fig. 3 b. The mandibles of the male 

 are not turned forward at the ends as much as in voltipis.

Argenna obeaa, new. 



Female 2.5 to 3 mm. long. Cephalothorax 1 mm. The whole 

 body pale, cephalothorax a little darker than the abdomen. The 

 hinder half of the abdomen indistinctly marked with angular spots. 

 PI. IV, fig. 4a. The abdomen is oval and longer than the cephalo- 

 thorax. The head is wide and but little elevated. Tlie front middle 

 eyes are smallest, but only a little smaller than the upper middle 

 pair, and the front ej'es form a nearly straight row at equal distances 

 from each other. The sternum is nearly as wide as long, and with 

 a blunt point behind that extends backward between the fourth 

 coxae. The cribellum is small and undivided. Fig. 4. The fourth 

 metatarsus is slightly curved and the calamistrum extends about 

 half its length. 



The male differs fr(jm the female in the smaller abdomen and 

 longer and larger front legs. The male palpi have both the patella 

 and tibia short and wide. The tarsus is nearly as wide as long and 

 pointed at the end. The tibia has a wide process that extends for- 

 ward along the outer side of the tarsus and against this lies a wide 

 pointed appendage of the palpal organ supporting the end of the 

 tube, somewhat as in Dictyna. Figs. 4 c, 4d, 4e.
