Fig. 8 f. The tibia is widened at the end as in Erigone and Gongy- 

 Hdium. At the base of the tarsus are three stiff bristles like those 

 of Tmeticus longisetosus. Fig. 8e. 



The female is 3 mm. long, colored as in the male, but paler. 

 The eyes have a similar arrangement, but are not elevated above 

 the cephalothorax. The mandibles are large but without unusual 

 processes and have five teeth on the front of the claw groove. 

 The maxillae are wide and project a little beyond the sternum. 

 The sternum is wide in front, widest between the first and second 

 legs, and projects backward between the fourth coxae. The epi- 

 gynum is shown in Fig. 8d. 



White Mountains, N. H., near the Crawford Notch, sifted from 

 leaves, Sept. 25, 1908. Banks described it from Manitoba. 



Tmeticus aestivalis, new. 



1.5 mm. long. Cephalothorax nearly as wide as long and the 

 abdomen narrower and oval. The sternum is as wide in front as 

 it is long, and varies in shape. In some males it is almost triangular, 

 with the sides straight and the widest part just behind the first legs, 

 but usually the sides are slightly curved to the fourth coxce, where 

 the sternum is very narrow and extends between them. The male 

 palpus has the tibia nearly as wide as long and divided at the front 

 end, the outer branch curving outward. The tarsal hook is larg^e 

 and grooved on the outer side with two teeth at the end, the outer 

 one largest and curved toward the other. At the end of the palpal 

 organ is a black forked appendage bent toward the bulb and pointed 

 forward and outward. PI. Ill, figs. 1, la, lb. 



The female is as large as the male, with the cephalothorax not 

 quite as wide. The epigynum appears without magnifying as two 

 parallel dark stripes, at the anterior end of which the small round 

 receptacles show through the skin. Fig. 1 c. 



Mt. Toby and Holden, Mass., in June under leaves. 



Tmeticus tarsalis, new. 



2 mm. long. Cephalothorax nearly as wide as long, with the 

 whole anterior half elevated. PL III, fig. 2. The e3'es are slightly 

 raised above the rest of the head and the front of the cephalo- 

 thorax from the eyes to the mandibles is nearly vertical. The 

 male palpi are as long as the cephalothorax, with the tarsus and 

 palpal organ large and rounded, and a very long tube thick at the 

 liase and coiled entirely around the tarsus. Fig. 2 a. The tibia is 

 short and small, showing above two short teeth. The tarsal hook
