Cornicularia tibialis, new. 



Plate XI, figure 2. 



This is a little smaller than directa. The colors are the same. 

 The horn is shorter and thicker. The tibia of the male palpus is 

 nearly as large as the tarsus. The hook has a large tooth in the niid- 

 dle, which is roughened on the edge and inside. Fig. 2a. Both 

 sexes are alike in size and color. 



From Mt. Tom, Hoi yoke, Mass. 



Cornicularia communis, new. 



Plate XI, figure 3. 



Cephalothorax dark orange, darkened with brown toward the 

 head and nearly black around tlie eyes. Legs brighter orange. 

 Palpi same color, except the tibia and tarsus which are dark brown. 

 Abdomen black with the muscular marks light yellow. Under side 

 of abdomen same color. Sternum dark orange like the back of 

 thorax. 



Horn of male pointing forward, about as long as the distance be- 

 tween the front and back middle eyes, widened at the end where it 

 is covered with stiff hairs directed upward and backward. Although 

 it appears single, the horn really consists of two, pressed closely to- 

 gether, the upper or posterioi- one forming the greater part of it and 

 bearing the terminal hairs. The anterior horn is entirely covered 

 above by the other.

Erigone indirecta, Oamb., Proc. Zool. Soc. London, 18*74. 

 Plate XI, figure 4. 



Cephalothorax and legs bright orange. Head black. Abdomen 

 lighter orange than thorax, both above and below. This species dif- 

 fers from coinmu?iis in the color of the abdomen and in having the 

 dark spot on the head darker and more definite and the palpi and 

 mandibles darker. Both sexes agree closely in size and color. The 

 hinder middle eyes are farther back than in conDminis. 



Horn of male like that of cotnmunis, Fig. 4, with recurved 

 hairs on the end and along the upper side. The palpi of the males 

 are much alike in these two species,
