Lophocarenum Menge. 

 These spiders form the greater part of the genus Lophocaremun of 

 Menge, although so)ne species are included in his LopJiouuna and 

 T'meticits. By Blackwall and Cambridge they are placed either in 

 Neriene or Wcdckenaera^ and by other autliors, with the other small 

 spiders of this family, in Erlgone. I include in tliis genus only those 

 spiders which have cavities in the heads of the males, opening by 

 holes near the eyes. Pis. 12, j3. The heads of the males are usually 

 high and furnished with humps of various shapes, according to the 

 species. The head of the female usually shows some traces of the 

 hump, and they resemble the males in color and form, so that after 

 the males are known the females can usually be identified. Nearly all 

 the species are small, 1 or 2'"'" long, and dull colored. Most of them 

 are short and stout with short legs. They live under leaves or on 

 low plants, though some sjiecies, as L. florens, are found on high 

 bushes in summer. The palpal organs are of various shapes, but the 

 tube is usually smooth and slender and the appendages small. The 

 tarsal hook is small. The tibia is large and of various shapes, accord- 

 ing to the species.

2.5111111 ioi^o\ Cephalothorax dark reddish brown. Legs orange- 

 brown. Abdomen black. The back part of the head is abruptly 

 elevated and carries the hind middle eyes on the front. Each side of 

 this hump is a groove in which are the holes leading to horn-shaped 

 cavities in the head. The palpal organs resemble those of Gornicula- 

 ria. The tarsal hook. Fig. \e^ is curved outward and lias a notch near 

 the middle Avhen seen sidewise. The tube of the palpal organ is long 

 and supported at the end by a flexible process. Fig. \e. 



Only males, from Beverly, Swampscott and Milton, Mass.

A little smaller than the last species, but resembling it very closely. 

 The cephalothorax is slightly narrower than in the last species, the 

 hum]) is indented in front below the upper eyes. The color is 

 yellowish brown on the cephalothorax and gray on the abdomen. 

 The palpi are much as in castaneum. Figs, ib, 2/. The female is 

 colored like the male, but has no elevation on the head. The 

 epigynum is short, with an oblique groove each side. Fig. 2//.
