eyes, the lobe on top yellow, a black line from the hole on each side ; 

 abdomen blackish above and below, the spinnerets pale, sternum yel- 

 lowish, legs and palpi pale, clothed with fine hairs. Just behind the eyes 

 is a large bilobed body with a hole at base each side ; seen from above 

 each lobe is elliptical, and scarcely twice as long as broad, shorter than 

 in D. bituberculatiis. Posterior row of eyes nearly straight ; P. M. E. 

 once and a half their diameter apart, slightly farther from the S. E.; A. 

 M. E. very small and about touching. Sternum as broad as long, 

 triangular ; legs moderately long, no spines above on tibiae, tarsus i. 

 shorter than metatarsus. The tibia of ^ palpus has a long projection 

 above near tip, much as in D. bituberculatus, but it is more slender, 

 more straight and but little curved at tip ; on the outer side of tibia is a 

 very small hook-shaped appendage ; the tube is moderately long, bent in 

 the middle, and the tip supported by a hyaline sheath. The palpi are 

 comparatively small. 



Two males, one from a deep swamp near Ithaca, N. Y., the other 

 from Olympia, Wash. [Trevor Kincaid]. 



Dicyphus tri/obatus., n. sp. 



Length, (J , 2 mm. Cephalothorax yellow-brown, black about the 

 eyes, lobe yellow ; abdomen black, with a few light cross-lines near tip ; 

 sternum and venter black; the spinnerets pale; legs and palpi yellowish, 

 a little brown on the coxae. Posterior row of eyes straight ; P. M. E. 

 twice their diameter apart, much closer to the S. E,; A. M. E. close 

 together, not so very much smaller than the S. E. Just behind the eyes 

 is a large triangular flat body, trilobed in front, the lobes of about equal 

 size. The sternum is broad, projecting between the hind coxae, the sides 

 rounded. Legs moderately long, hairy, no spines on tibife. The S 

 palpi are long and slender, the tibia has above a large bifid process ; 

 there are two tube-like pieces : one, starting from near the middle of the 

 bulb, bends out and then toward the tip of the palpus ; the other, starting 

 from near the inner tip of bulb, extends toward the base of the first one ; 

 on the outer side there is a quite prominent pale-coloured projection — it 

 is somewhat like a sheath or support for the tube. 



One specimen from Ithaca, N. Y. 



The genus Erigonoplus has the head lobed as in the preceding 

 genera, but differs from them at once in having the anterior metatarsi of 

 the male swollen.
